Hot exozodiacal dust can thwart our efforts to detect exoplanets. It causes what's called coronagraphic leakage, which confuses the light signals from distant stars. The Habitable Worlds Observatory will face this obstacle, and new research sheds light on the problem.
A video that appeared on CGTN's Hot Take details four missions that China will be sending to space in the coming years, including a survey telescope that will search for Earth 2.0.
A powerful geomagnetic superstorm is a once a generation event, happening once every 20-25 years. Such an event transpired on the night of May 10/11, 2024, when an intense solar storm slammed into the Earth’s protective magnetic sheath. Now, a recent study shows just how intrusive that storm was, and how long it took for the Earth’s plasma layer took to recover.
Observations with the SPHERE instrument on the European Southern Observatory's VLT revealed the presence of debris rings similar to structures in our Solar System. SPHERE found rings similar to the Kuiper Belt and the Main Asteroid Belt. Though individual asteroids and comets can't be imaged, these debris rings infer that other solar systems have architectures similar to ours.
It’s been over two years since the samples from Bennu gathered by OSIRIS-REx were returned to Earth. But there’s still plenty of novel science coming out of that 121.6 g of material. Three new papers were released recently that describe different aspects of that sample. One in particular, from Yoshihiro Furukawa of Tohoku University in Japan and their co-authors, has already attracted plenty of attention, including from US Senator (and former astronaut) Mark Kelly. It shows that all of the building blocks for early life were available on the asteroid - raising the chances that planets throughout the galaxy could be seeded with the abiotic precursors for life.
What can mapped drainage systems on Mars teach scientists about the Red Planet’s watery past? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists from the University of Texas at Austin (UT Austin) conducted a first-time mapping study involving Martian river basins. This study has the potential to not only gain insight into ancient Mars and how much water existed there long ago but also develop new methods for mapping ancient river basins on Mars and potentially other worlds.
Scientists have launched COLIS, a special laboratory aboard the International Space Station designed to study how everyday materials like sunscreens, mayonnaise, and medications behave in near zero gravity. Researchers discovered that gravity influences the long term stability of soft matter far more dramatically than previously understood, affecting how these materials age and restructure at the molecular level. This research could fundamentally improve how we design everything from controlled release drugs to self assembling materials, demonstrating that understanding materials in space offers unexpected benefits for life on Earth.
On a summer day in 709 BCE, scribes at the Lu Duchy Court in ancient China looked up to witness something extraordinary. The Sun vanished completely from the sky, and in its place hung a ghostly halo. They recorded the event carefully, noting that during totality the eclipsed Sun appeared "completely yellow above and below." Nearly three millennia later, that ancient observation has helped modern scientists measure how fast Earth was spinning and understand what our Sun was doing at a time when Homer was composing poetry.
Dr. Makary desperately wants everyone to know he is a brave, free-thinker, able to see the world objectively and without bias, smarter than 99% of his peers. However, in reality his brain is cooked.
