Dark Matter Could Create Dark Dwarfs at the Center of the Milky Way

Universe Today - Thu, 07/10/2025 - 7:47am

Although dark matter doesn't seem to interact with regular matter or itself, if it has particle-like properties, it could self-annihilate if packed into a tight space. In a new paper, researchers have proposed that dark matter could make its way into brown dwarfs near the Galactic Center, where everything is packed more closely together. The dark matter could annihilate inside the brown dwarfs, creating Dark Dwarfs that could be detected.

High Frequency Gravitational Waves Could Be Detect By Changing The Angle Of A Mirror

Universe Today - Thu, 07/10/2025 - 7:47am

Gravitational waves come in all shapes and sizes - and frequencies. But, so far, we haven’t been able to capture any of the higher frequency ones. That’s unfortunate, as they might hold the key to unlocking our understanding of some really interesting physical phenomena, such as Boson clouds and tiny block hole mergers. A new paper from researchers at Notre Dame and Caltech, led by PhD student Christopher Jungkind, explores how we might use one of the world’s most prolific gravitational wave observatories, GEO600, to capture signals from those phenomena for the first time.

Planets Can Trigger Damaging Flares

Universe Today - Thu, 07/10/2025 - 7:47am

We all know what it's like when Earth is on the receiving end of a solar flare. Things get spicy in the upper atmosphere, and the outbursts have the potential to disrupt technology here at home. Catastrophic flares of radiation devastate planets around other stars, too. Now it looks like scientists have found that planets orbiting close to their stars can trigger the flares that threaten to harm them.

How the Chemistry of Mars Both Extended and Ended Its Habitability

Universe Today - Thu, 07/10/2025 - 7:47am

NASA's Curiosity Rover has been exploring Gale Crater and found that carbonate materials make up to 11% of rocks in the region. These are important because carbonates formed by pulling CO2 out of Mars's atmosphere. A new paper suggests that Mars once had a self-regulating climate system that created oases of liquid water on its surface over billions of years, keeping the planet barely habitable with alternating wet and dry periods. The atmosphere is thin because its CO2 was locked away in rocks.
