A New Neutrino Detector In China Is Coming Online

Universe Today - Sat, 09/13/2025 - 7:27am

Neutrinos are one of the most enigmatic particles in the standard model. The main reason is that they’re so hard to detect. Despite the fact that 400 trillion of them created in the Sun are passing through a person’s body every second, they rarely interact with normal matter, making understanding anything about them difficult. To help solve their mysteries, a new neutrino detector in China recently started collecting data, and hopes to provide insight on between forty and sixty neutrinos a day for the next ten years.

Young Stars Hold the Key to Solar Storms

Universe Today - Sat, 09/13/2025 - 7:27am

Just as Earth has its four familiar seasons, our Sun experiences its own version of seasonal cycles that affect life on our planet. But unlike Earth's yearly rhythm, the Sun's "seasons" unfold over an 11 year magnetic cycle that scientists are now understanding in entirely new ways.

Predicting the Green Glow of Aurora on Mars

Universe Today - Sat, 09/13/2025 - 7:27am

For the second time in history, the gentle glow of the aurora has been captured in Mars's night sky. It’s a phenomenon we enjoy here on Earth and we can, to a varying degree of success predict its appearance. Now a team of scientists are learning how to predict when these spectacular light shows will happen on Mars too. It's a breakthrough that could one day help protect future astronauts on the red planet while also helping us to understand these beautiful displays work in alien skies.

Enceladus, The Life Signs That Weren't

Universe Today - Sat, 09/13/2025 - 7:27am

I still remember the first time I saw Saturn through a 10 inch telescope when I was ten years old. It looked just like it did in pictures, a pale yellow disk circled by its stunning ring system. What I couldn't see then were Saturn's moons, including the small, icy world of Enceladus that has since become one of the most exciting targets in the search for life beyond Earth. This tiny moon shoots spectacular plumes of water from cracks in its frozen surface, plumes that contain organic molecules. But a new study suggests we shouldn’t get too excited about what these molecules actually tell us about the possibility of life.

This Star Is Consuming Its Companion And Could Explode Brilliantly

Universe Today - Sat, 09/13/2025 - 7:27am

A binary star that has puzzled astronomers for decades may finally be explained. The accretor star is sucking material from its donor star so rapidly that it can't contain it all and is forming a bright, circumbinary ring.

Stellar Slingshots Launch the Galaxy's Fastest Stars

Universe Today - Sat, 09/13/2025 - 7:27am

It’s really quite reasonable to assume the stars don’t move! Indeed that was the opinion of our ancestors however we now know they are far from stationary. Imagine a star racing through space so fast it could travel from Earth to the Moon in just three minutes. These are known as hypervelocity white dwarfs and they have puzzled astronomers for years. Now, a team of researchers have finally cracked the mystery of how they get launched at such incredible speeds.

Where Did The Interstellar Comet 3I/ATLAS Come From?

Universe Today - Sat, 09/13/2025 - 7:27am

When an interstellar object (ISO) travels through our inner Solar System, the immediate question is "Where did it come from?" There are only fleeing opportunities to study these, since their trajectories take them out of the Solar System pretty quickly. A new research effort aims to understand where the most recent ISO, 3I/ATLAS, originated.

Hunting for Aliens in the Galaxy's Most Promising Neighbourhood

Universe Today - Sat, 09/13/2025 - 7:27am

Are we alone in the universe? It’s a question that has, despite extensive and sometimes ingenious attempts, yet to be answered. In one of the most ambitious searches for extraterrestrial intelligence ever conducted, Chinese scientists have used the world's largest radio telescope to scan the famous TRAPPIST-1 star system for signs of alien technology. The Five hundred metre Aperture Spherical Telescope is the world's largest single dish radio telescope, and the search for extraterrestrial intelligence (SETI) is one of its five key science objectives.

JWST Finds An Exoplanet Around A Pulsar Whose Atmosphere Is All Carbon

Universe Today - Sat, 09/13/2025 - 7:27am

Science advances through data that don’t fit our current understanding. At least that was Thomas Kuhn’s theory in his famous On the Structure of Scientific Revolutions. So scientists should welcome new data that challenges their understanding of how the universe works. A recent paper, available in pre-print on arXiv, using data from the James Webb Space Telescope (JWST) might just have found some data that can do that. It looked at an exoplanet around a millisecond pulsar and found its atmosphere is made up of almost entirely pure carbon.

This Wandering Black Hole Has Left Its Galactic Center

Universe Today - Sat, 09/13/2025 - 7:27am

Traditionally, black holes are usually thought to reside at the centers of galaxies. However, a research team led by Dr. An Tao from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has discovered a wandering black hole in a dwarf galaxy located about 230 million light-years away.

One Wrong Hit Could Send an Asteroid on a Collision Course with Earth

Universe Today - Sat, 09/13/2025 - 7:27am

It was a chilly night when I peered through my 10” Meade LX200 telescope from Norfolk in the UK! I wasn’t completely convinced it would appear nor even be visible but bang on the prediction, asteroid 2002 MN drifted by my field of view and I was amazed at how accurately we could predict its path! That precision in tracking asteroid trajectories has become even more critical now that we're actively exploring how we can deflect them. A team of scientists have made a discovery about asteroid deflection that's both fascinating and sobering at the same time. Hit an asteroid in the wrong spot, and you might accidentally steer it through a "gravitational keyhole" that sending it back toward Earth years later.

A Bi-Directional Plasma Thruster Could Deorbit Space Junk Safely

Universe Today - Sat, 09/13/2025 - 7:27am

There are plenty of labs working on solutions to Kessler Syndrome, where there’s so much debris in low Earth orbit that rockets are no longer capable of reaching it without being hit with hypersonic parts of defunct equipment. While we haven’t yet gotten to the point where we’ve lost access to space, there will come a day where that will happen if we don’t do something about it. A new paper from Kazunori Takahashi of Tohoku University in Japan looks at a novel solution that uses a type of magnetic field typically seen in fusion reactors to decelerate debris using a plasma beam while balancing itself with an equal and opposite thrust on the other side.

Makemake's Secret Finally Revealed

Universe Today - Sat, 09/13/2025 - 7:27am

As someone who has lectured for more years than I care to remember and written books about space, I've grown accustomed to constantly rewriting sections as new discoveries emerge. The discovery of the dwarf planet Makemake led to such rewrites, but until now we didn't know much about this elusive world. A team of scientists at the Southwest Research Institute has recently changed that with their detection of methane gas on Makemake using the James Webb Space Telescope. It's exactly the kind of discovery that sends authors like me back to the drawing board, because this finding doesn't just add another detail to Makemake's story, it fundamentally changes how we view these distant worlds.

The Gemini South Telescope Takes A Turn Imaging The Interstellar Comet 3I/ATLAS

Universe Today - Sat, 09/13/2025 - 7:27am

Interstellar comets are rare, and astronomers don't like to miss an opportunity to observe one. Now the Gemini South Telescope has taken a turn at imaging Comet 3I/ATLAS, the visitor from another star system. The images help show that the comet's tail is growing as it approaches the Sun.

The Universe's Early Star Formation Wasn't Much Different Than Now

Universe Today - Sat, 09/13/2025 - 7:27am

A team of Japanese astronomers has detected protostellar outflow jets in the outer regions of the Milky Way. This is the first detection of this type of jets in this part of the galaxy. Since this part of the galaxy is similar to the more ancient Universe, it's evidence that star formation in the modern Universe is similar to star formation in the ancient Universe.
