SNAPPY CubeSat Takes Flight to Test Space-Based Neutrino Detectors

Universe Today Feed - Thu, 05/21/2026 - 5:26am

Neutrinos, the second most common fundamental particles in the universe, are notoriously difficult to detect. So far we’ve only been able to do so by building giant vats of water far underground with hundreds of photodetectors watching for brief flashes of light. But a new CubeSat mission hopes to change that dynamic and enable the neutrino detectors of the future a much less constrained and expensive existence - in space.

Women’s better memories may delay Alzheimer’s diagnosis by years

Scientists discover strange “narwhal” waves that trap light beyond known limits

Matter and energy from Science Daily Feed - Thu, 05/21/2026 - 4:22am
Physicists at Peking University have uncovered a new way to confine light far beyond conventional limits — without relying on metals and their inherent energy dissipation. By formulating the singular dispersion equation, the team discovered narwhal-shaped wavefunctions that trap light at deep-subwavelength volumes in purely dielectric materials. The advance, dubbed singulonics, could pave the way for ultra-efficient photonic chips, new quantum technologies, and imaging tools with unprecedented resolution.

Physicists finally solve the strange mystery of “breathing” lasers

Matter and energy from Science Daily Feed - Thu, 05/21/2026 - 1:28am
Scientists have finally figured out how mysterious “breather” laser pulses work, solving a puzzle that has frustrated laser physicists for years. These unusual ultrafast lasers produce light pulses that rhythmically grow and shrink instead of staying steady, almost like they’re breathing.

Jupiter’s lightning may be 100x more powerful than Earth’s

Space and time from Science Daily Feed - Wed, 05/20/2026 - 11:46pm
Jupiter’s storms aren’t just gigantic — they may unleash lightning far more powerful than anything on Earth. Using NASA’s Juno spacecraft, scientists discovered that some lightning bolts on the gas giant could pack up to 100 times the punch of Earth’s lightning, and possibly much more. The findings reveal that Jupiter’s atmosphere works very differently from our own, with massive storms building enormous amounts of energy before erupting in violent flashes across cloud tops towering more than 100 kilometers high.

Scientists discover a strange “inside-out” planetary system that shouldn’t exist

Space and time from Science Daily Feed - Wed, 05/20/2026 - 11:09pm
Scientists have discovered a bizarre planetary system where a rocky world orbits farther out than giant gas planets, defying long-standing theories of planet formation. The finding hints that some planets may form much later than expected — and that our Solar System might not be as typical as we thought.

New quantum sensor could count individual photons and hunt dark matter

Matter and energy from Science Daily Feed - Wed, 05/20/2026 - 7:42pm
Researchers have built an ultra-sensitive sensor capable of detecting unimaginably small amounts of energy — below one zeptojoule. The breakthrough relies on fragile superconducting materials that react to even the slightest temperature change. This level of precision could improve quantum computers, enable photon counting, and even help scientists detect elusive dark matter particles from space.

Future Mars Rovers Could Mimic a Swimming Motion to Traverse the Planet's Surface

Universe Today Feed - Wed, 05/20/2026 - 3:33pm

Some animals can move efficiently beneath granular surfaces. These include the sandfish (Scincus scincus), a lizard native to the Sahara. It can burrow into the sand and then literally "swim" through the desert sand to hunt or escape predators. German researchers are working on a rover wheel design that mimics that swimming motion. In testing, the wheel system outperformed regular wheels.

Hellish Venus-Like Planets May Be More Prevalent Than True ExoEarths

Universe Today Feed - Wed, 05/20/2026 - 3:08pm

Exoplanet hunters are keen to find the next extrasolar earthlike planet, one that may harbor life as we know it. But preliminary results from a new study indicate that our galaxy may be filled with a plethora of exo-Venuses. Yet as one exoplanetary researcher notes: the template for such exo-worlds --- our own Venus --- has been ‘criminally underexplored.’

NASA's Psyche Mission Says Goodbye to Mars and Heads for its Metal-Rich Target

Universe Today Feed - Wed, 05/20/2026 - 1:42pm

Spacecraft often use planets for gravity-assist or "slingshot" maneuvers. NASA's Psyche mission used Mars for that purpose during a May 15th flyby. The flyby accelerated the spacecraft and aimed it at its eventual destination, the asteroid 16 Psyche. The flyby was also an opportunity to take some pictures of Mars, and to test and calibrate the spacecraft's science instruments.

Joni!

Why Evolution is True Feed - Wed, 05/20/2026 - 11:30am

Here’s an entire BBC concert by Joni Mitchell, filmed in September, 1970. I’ve always thought that BBC concerts were the best, as they will always live and without accompaniment.  This one is 48 minutes long, and she had long career after this with some great albums (“Blue,” “For the Roses” and “Court and Spark”).

I have nothing to add to this music save to say that I think she’s the greatest combination of singer, songwriter, and instrumentalist of our time, and like most boys my age (I was 21), I was hopelessly in love with her. James Taylor, who also had a BBC concert that same year, rivals her on the male side for the trio of talents, but Joni has the overall edge.

Oh, and some of my favorite songs here are “Chelsea Morning” (at the start), “My Old Man” (16:47), “Woodstock” (25:10), “All I Want” (31:00, on the dulcimer), “All I Want” (31:45), “California” (36:45), and of course “Both Sides Now” (44:25)

Can you imagine being in the audience and hearing these songs for the first time?

The first comment is ineffably poignant:

I am at the end of my life, 68 years old and in hospice…dying with leukemia. I remember owning my first JONI MITCHELL album with clouds and Michael from mountains, Nathan la frenier, etc…. it changed my life and initiated my music career. I have lived lifetimes since then and changed careers several times. Now, resting on my couch, I listen to this old concert and remember how I felt when I was 13 years old and just hearing these songs for the very first time. at the time she was the older wiser woman whom I wanted to emulate…. now, watching this, she is dewy youth and I the rusk, ready to blow away on the wind with a song in my heart

It Looks Like Europa Doesn't Have Plumes of Water Vapour After All

Universe Today Feed - Wed, 05/20/2026 - 11:12am

In 2014, researchers presented the discovery of water vapour plumes being emitted from Jupiter's moon Europa. This caused quite a stir; it meant that the moon's buried ocean was accessible without contending with the thick ice shell that concealed it. But new research by the same researchers questions those detections.
