Humanity will eventually need somewhere to live on the Moon. While aesthetics might not be the primary consideration when deciding what kind of habitat to build, it sure doesn’t hurt. The more pleasing the look of the habitat, the better, but ultimately, the functionality will determine whether or not it will be built. Dr. Martin Bermudez thinks he found a sweet synergy that was both functional and aesthetically pleasing with his design for a spherical lunar habitat made out of blown glass. NASA apparently agrees there’s potential there, as he recently received a NASA Institute for Advanced Concepts (NIAC) Phase I grant to flesh out the concept further.

Bermudez’s vision’s artistic design looks like something out of an Arthur C. Clarke novel: a glass sphere rising off the lunar surface that could potentially contain living and work areas for dozens of people. His firm, Skyeports, is founded on creating these blown glass structures in space.

The design has some challenges, as Dr. Bermudez discusses in an interview with Fraser. First is how to build this thing. It’s far too large to ship in any conventional lunar lander. However, there’s also no air on the Moon to use as the blown gas to create the spherical shape. Dr. Bermudez plans to utilize argon, which would initially be shipped up from Earth to fill the sphere. Argon has several advantages in that it’s a noble gas and not very reactive, so it’s unlikely to explode in the furnace while the glass is blown.

Surprisingly, the lack of outside air pressure actually makes it easier to form a sphere than it would be on Earth since less pressure would be necessary to expand the sphere outwards. There are some nuances in the glass as well, with it being more like a glass lattice with embedded titanium or aluminum to make it stronger. Specific kinds of glass, such as borosilicate glass, could potentially add to the strength of the glass itself.

Most of the materials required to create such a structure could already be found on the lunar surface. Lunar regolith is full of the raw building materials required to make the structure work. Some of it has already been blasted into glass-like structures called agglutinates when micrometeoroids hit the lunar surface.

Those micrometeoroid impacts pose another risk to the glass sphere. Dr. Bermudez suggests having multiple layers of glass protecting the habitat, each with a layer of argon between them, like modern-day double-glazed windows. He suggests that spinning the outer layer might also provide some advantage, as will the spherical shape itself, as the impact force will dissipate better into the structure than it would on a flat surface.

3D printing is one of the fabrication technologies the blown glass sphere will have to compete with, as Fraser discusses.

Dr. Bermudez’s dreams don’t stop at the Moon, though. He suggests such a glass-blown structure could be useful on Mars or asteroids, where the microgravity would make it even easier to create these structures. On Mars, such a habitat might be limited to the top of Olympus Mons, where the atmosphere is thinner, and there isn’t as much wind and dust that could erode away the outer layers.

Many use cases exist for a structure like this, though many technical challenges remain. NIAC is the place for novel ideas that could potentially impact space exploration, and this one certainly fits that bill. As Dr. Bermudez works through de-risking his design, we get closer than ever to a future of aesthetically pleasing habitats on the Moon and everywhere else in the solar system.

In lieu of readers’ wildlife today, I’ll show some drawings and photos in honor of Darwin’s Birthday.  (Note to those malcontents who think that evolution is a religion that worships Darwin as a God: no, we do not think Darwin is infallible. He made a lot of errors, and his neglect of genetics and of how species really arise are big lacunae. Nevertheless, he’ll gone down in history as perhaps the most influential biologist ever.)

A big Darwin Award for this:

Darwin was born in Shrewsbury on this day in 1809 and attended Shrewsbury School as a boarder beginning at age 8. He went to the University of Edinburgh Medical School in 1825, but couldn’t stand the sight of blood and preferred collecting beetles. He dropped out and attended Cambridge University until 1831, when he started on the epic five-year voyage of the Beagle.  Here is his statue is in front of Shrewsbury School:

Darwin was pretty well off, and became more so when he married Emma Wedgwood, heiress of the Wedgwood pottery company. He married Emma in 1839 and in 1842 they moved to Down House in Kent (visit it; it’s not far from London!).  The couple had ten children, seven of whom survived. Darwin lived at Down House the rest of his life (he died in 1882), and it was there that he wrote On the Origin of Species and all his subsequent books. Here’s his study in Down House, which is pretty much as it was when he worked there.  I understand that he wrote in the chair, using a board placed over the arms. There’s also a basin behind a screen where Darwin would go to vomit, for he was often ill with a disease that we still don’t understand.

It’s me at Down House: August 19, 2008. You can see that Darwin had a nice mansion:

My friend Andrew Berry, who went to Shrewsbury School, and Janet Browne, who wrote the definitive biography of Darwin (two volumes). It is magnificent and written beautifully: a must-read. Janet showed us around Down House, which was a rare opportunity! I understand she’s revising it into one volume, perhaps because people lack attention spans these days, but I’d read the two-volume bio.

A cat I photographed at Down House. Darwin didn’t have much truck with cats and preferred d*gs. However, there are cats there now:

A groundbreaking study has uncovered how specific genetic mutations influence cancer treatment outcomes -- insights that could help doctors tailor treatments more effectively. The largest study of its kind, the research analyzed data for more than 78,000 cancer patients across 20 cancer types. Patients received immunotherapies, chemotherapies and targeted therapies.

How can a geologic map of a lunar impact crater created billions of years ago help future human and robotic missions to the lunar surface? This is what a recent study published in The Planetary Science Journal hopes to address as an international team of researchers produced arguably the most in-depth, comprehensive, and highest resolution geologic maps of Orientale basin, which is one of the largest and oldest geologic structures on the Moon. This study has the potential to help scientists, engineers, and mission planners develop sample return missions that could place absolute ages on the Moon’s geology, resulting in better understanding the formation and evolution of our Moon and the Earth.

For the study, the researchers created a 1:200,000-scale geologic map of the Moon’s Orientale basin while focusing on identifying what are known as impact melt deposits, which are molten rocks created from a high-speed impact and intense heat that cooled and is now frozen in time, thus preserving its geologic record of when it was formed billions of years ago. The 1:200,000-scale means the map is 200,000 times smaller than in real life. Additionally, one pixel on the geologic map is equal to 100 meters, or approximately the size of an American gridiron football field, which improves upon previous Orientale basin geologic maps that were created at 1:5,000,000-scale.

“We chose to map Oriental basin because it’s simultaneously old and young,” said Dr. Kirby Runyon, who is a Research Scientist at the Planetary Science Institute and lead author of the study. “We think it’s about 3.8 billion years old, which is young enough to still have its impact melt freshly exposed at the surface, yet old enough to have accumulated large impact craters on top of it as well, complicating the picture. We chose to map Orientale to test melt-identification strategies for older, more degraded impact basins whose ages we’d like to know.”

The goal of the study is to not only create an improved geologic map of Orientale basin, but to provide a foundation for future missions to potentially obtain surface samples of the impact melt and return them to Earth for analysis. Such analyses would reveal absolute ages of the impact melt through radiometric dating since these samples have been frozen in time for potentially billions of years. These results could help scientists unravel the Earth’s impact history, as both the Earth and Moon were potentially formed around the same period.

Along with the targeted impact melt, the team successfully identified and mapped a myriad of geologic features within Orientale basin as part of the new geologic map, including smaller craters within Orientale, fractures, fault lines, calderas, crater ejecta, and mare (volcanic basalt deposits), while also constructing a top-to-bottom map of Orientale basin, also called a stratigraphic map, that shows the most recent layers on top with the oldest layers on the bottom.

Unlike Earth, whose surface processes like plate tectonics and multitude of weather processes have erased impacts from billions of years ago, the preserved lunar geologic record could provide incredible insight into not only Earth’s impact history, but both how and when life first emerged on our planet. This is due to Orientale basin’s crater size and age, as such a large impact on Earth billions of years ago could have postponed or reset how and when life first emerged on the Earth.

“Giant impacts – like the one that formed Orientale – can vaporize an ocean and kill any life that had already started,” said Dr. Runyon. “Some recent modeling has shown that we probably never totally sterilized Earth during these big impacts, but we don’t know for sure. At some point our oceans could have been vaporized from impacts, then recondensed and rained out repeatedly. If that happened a number of times, it’s only after the last time that life could have gotten a foothold.”

While Orientale basin is one of the most striking features on the lunar surface, more than approximately 75 percent of it is not visible from Earth due to its location at the lunar nearside and farside boundary on the western limb of the Moon as observed from the Earth. Therefore, studying the Orientale basin is only possible with spacecraft. Despite this, Orientale basin was first suggested to be an impact crater during the 1960s when scientists at the University of Arizona’s Lunar and Planetary Laboratory used groundbreaking techniques to “image” the sides of the Moon not visible to Earth using telescopic images taken from the Earth.

While NASA is focused on returning astronauts to the lunar surface with its Artemis program with the goal of establishing a permanent human presence on the Moon, returning scientific samples from Orientale basin could provide enormous scientific benefits for helping us better understand both the age of the Moon but also how and when life emerged on Earth billions of years ago.

How will the Orientale basin geologic map help us better understand the Moon’s and Earth’s history in the coming years and decades? Only time will tell, and this is why we science!

As always, keep doing science & keep looking up!

We have the transit method to thank for the large majority of the exoplanets we’ve discovered. When an exoplanet transits its star, the dip in starlight tells astronomers that a planet is present. Analyzing the light can tell them about the planet’s size and atmospheric properties. However, a star’s surface isn’t always uniformly heated. There can be hotter, brighter spots and colder, dimmer spots that change over time.

New research says these temperamental stars are distorting our understanding of exoplanets.

The number of confirmed exoplanets is approaching 6,000. Astronomers want to understand these planets better in all their bewildering variety. The only way to do that is to examine light and how it changes in exquisite detail. When an exoplanet transits in front of its host star, astronomers can ‘read’ the starlight as it passes through the planet’s atmosphere.

However, new research shows that the stars that host all these planets can pollute the light signal from their orbiting planets, giving us a distorted view of their sizes, temperatures, and atmospheres.

The research is “A Population Analysis of 20 Exoplanets Observed from Optical to Near-infrared Wavelengths with the Hubble Space Telescope: Evidence for Widespread Stellar Contamination,” and it’s published in The Astrophysical Journal Supplement Series. The lead author is Arianna Saba from the Department of Physics and Astronomy at University College London.

A star’s surface is defined in large part by its temperature, which is influenced by the star’s powerful magnetic fields. Magnetic fields can inhibit the heat flow from a star’s interior to its surface, creating a cooler, dimmer region. Conversely, it can channel more heat into other areas, creating brighter regions.

“Some stars might be described as ‘patchy’ – they have a greater proportion of colder regions, which are darker, and hotter regions, which are brighter, on their surface. This is due to stronger magnetic activity,” said study co-author Alexandra Thompson.

“Hotter, brighter regions (faculae) emit more light, and so, for instance, if a planet passes in front of the hottest part of the star, this might lead researchers to over-estimate how large the planet is, as it will seem to block out more of the star’s light, or they might infer the planet is hotter than it is or has a denser atmosphere,” Thompson explained. “The reverse is true if the planet passes in front of a cold starspot, making the planet appear ‘smaller.’

These temperamental stars can also produce false positives.

“On the other hand, the reduction in emitted light from a starspot could even mimic the effect of a planet passing in front of a star, leading you to think there might be a planet when there is none. This is why follow up observations are so important to confirm exoplanet detections,” said Thompson.

The question is, how much of our understanding of these exoplanets is polluted by these patchy stars? Is stellar contamination creating a bias in our understanding of the exoplanet population?

To find out, Saba and her co-researchers examined the archival data from 20 exoplanet atmospheres previously observed with the Hubble’s Space Telescope Imaging Spectrograph (STIS) and Wide Field Camera 3 (WFC3) instruments. These workhorse instruments “see” in UV, infrared, and visible light. They wanted to know if observations taken with the same instruments at different times produced different results and if any differences were confined to observations in specific wavelengths.

“To obtain spectral information from the near-ultraviolet to the near-infrared, we reanalyzed 16 WFC3 and over 50 STIS archival data sets with our dedicated HST pipeline,” the authors write in their paper. “Across our target sample, we observe significant divergence among multiple observations conducted with the same STIS grating at various epochs, while we do not detect variations in the WFC3 data sets.”

This suggested that stellar contamination is an issue, but the researchers dug deeper to understand how. Using Bayesian tools and other analytic models, they found that stellar activity had contaminated about half of the exoplanet atmospheres in their sample to varying degrees. Six of the exoplanets had pronounced contamination, and six others had lesser degrees of contamination.

“These results were a surprise – we found more stellar contamination of our data than we were expecting,” said lead author Saba. “This is important for us to know. By refining our understanding of how stars’ variability might affect our interpretations of exoplanets, we can improve our models and make smarter use of the much bigger datasets to come from missions including James Webb, Ariel and Twinkle.” Twinkle is a low-cost mission that will study exoplanet atmospheres from Low-Earth Orbit.

This figure from the paper illustrates some of the divergent results from observing exoplanets in different epochs. There was significantly more divergence among STIS observations than among WFC observations. STIS G430 and G750L are different gratings, and G102 and G141 are different WFC grisms. Image Credit: Saba et al. 2025.

Stellar contamination of exoplanet observations is no small matter. It can skew results in very pronounced ways. “Accounting for stellar activity can significantly alter planetary atmospheric parameters like molecular abundances (up to 6 orders of magnitude) and temperature (up to 145%), contrasting with the results of analyses that neglect activity,” the authors write in their paper.

According to the researchers, there are two ways to determine if stellar variability is affecting exoplanet data.

“One is to look at the overall shape of the spectrum – that is, the pattern of light at different wavelengths that has passed through the planet from the star – to see if this can be explained by the planet alone or if stellar activity is needed,” said Saba. “The other is to have two observations of the same planet in the optical region of the spectrum that are taken at different times. If these observations are very different, the likely explanation is variable stellar activity.”

One of the key findings concerns optical and UV observations. Since stellar activity is much more visible in optical and UV, exoplanet observations based on these wavelengths are more likely to reveal the contamination. Conversely, IR observations may overlook the contamination.

“Our results emphasize the importance of considering the effects of stellar contamination in exoplanet transit studies; this issue is particularly true for data sets obtained with facilities that do not cover the optical and/or UV spectral range where the activity is expected to be more impactful but also more easily detectable,” the paper states.

“The risk of misinterpretation is manageable with the right wavelength coverage,” said Thompson. “Shorter wavelength, optical observations such as those used in this study are particularly helpful, as this is where stellar contamination effects are most apparent.”

This issue clearly needs more investigating, and the researchers say they’ve identified stars that need more follow-up. They also explain that previous exoplanet atmosphere studies should be revisited, especially ones that lacked broad optical or UV coverage. By the same token, future exoplanet atmospheric studies should be multi-wavelength.

According to the authors, the active stars identified in this research should also be studied more thoroughly. This will increase astronomers’ understanding of how they influence observations of exoplanet atmospheres. Better models and analytic tools are also needed.

We’re still in the very early days of examining exoplanet atmospheres, so these results aren’t exactly surprising. The JWST is probing some exoplanet atmospheres, and future missions like the ESA’s ARIEL (Atmospheric Remote-Sensing Infrared Exoplanet Large survey) will do the same. ARIEL will perform the first large-scale survey of the chemistry of exoplanet atmospheres, highlighting the significance of these results.

“Our findings demonstrate the significant role that stellar contamination may have in all exoplanet spectra observations,” the authors write in their conclusion. “Therefore, comprehending, modeling, and correcting for the impact of stellar activity is important for a complete characterization of exoplanet atmospheres.”

Critics have been calling for NASA to cancel its extremely pricey Space Launch System rocket for ages, but now that it seems to be facing the axe from Elon Musk’s government efficiency task force, it may be time to think again

During the 1970s, while probing distant galaxies to determine their mass, size, and other characteristics, astronomers noticed something interesting. When examining the rate at which these galaxies rotated (their rotational curves), they found that the outer parts were rotating faster than expected. In short, their behavior suggested that they were far more massive than they appeared to be. This led to the theory that in addition to stars, gas, and dust, galaxies were surrounded by a “halo” of mysterious, invisible mass – what came to be known as Dark Matter (DM).

It was famed astronomer Vera C. Rubin, for whom the Vera C. Rubin Observatory (formerly the LSST) is named, who first proposed that DM played an important role in galactic evolution. Astronomers have since theorized that DM haloes must have existed shortly after the Big Bang and were integral to the formation of the first galaxies. In a recent study, an international team examined the core regions of two galaxies that existed 13 billion years ago. Their observations confirmed that DM dominated the haloes of these quasars, offering fresh insight into the evolution of galaxies in the very early Universe.

The research team was led by Qinyue Fei, a graduate student and visiting researcher from Peking University, and his colleagues from the University of Tokyo’s Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU). They were joined by researchers from Peking University’s Kavli Institute for Astronomy and Astrophysics (KIAA-PKU), the Center for Astrophysical Sciences at John Hopkin’s University, the Kavli Institute for Cosmology, Cambridge (KICC), multiple observatories and universities. Their study was published on February 5th in The Astrophysical Journal.

Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), the team was able to visualize the emission line of ionized carbon (C II) in two galaxies located 13 billion light years away. Like the “hydrogen line” (H I), this refers to the spectral line created by the transition of elemental carbon into ionized carbon. This way, they were able to study the gas dynamics within the Active Galactic Nuclei (AGNs, or quasars) of these very early galaxies. The active nature of these galaxies indicates that they have supermassive black holes (SMBH) at their centers.

They then employed numerous models to determine the velocity of the gases (nonparametric) the mass distribution (parametric) of the galaxies. This was assisted by DysmalPy and 3DBarolo, two software tools specifically designed to measure the rotation curves of galaxies. According to their results, which captured the rotation curves from the inner regions to the outskirts, DM accounted for about 60% of these early galaxies. “Vera Rubin provided the first evidence for dark matter using the rotation curves of nearby local galaxies. We’re using the same technique but now in the early Universe,” said Kavli IPMU Professor (and study co-author) John D. Silverman.

Interestingly, previous studies of galaxies in the early Universe revealed a low mass fraction of DM in their outskirts. However, the data obtained by Fei and his colleagues showed a flat rotational curve, similar to massive disk galaxies observed in the local Universe. The team’s findings shed light on the intricate relationship between DM matter and SMBHs and offer crucial hints as to how galaxies evolved from the early Universe to what we observe today.
