Once you can accept the Universe as matter expanding into nothing that is something, wearing stripes with plaid comes easy.

The Milky Way Could be Surrounded by 100 Satellite Galaxies

Universe Today - Wed, 07/16/2025 - 7:27pm

The Milky Way is surrounded by about 60 satellite galaxies. The famous ones are the Large and Small Magellanic Clouds. But according to a new simulation, the Milky Way could have 80 and even 100 satellite galaxies that we haven't detected so far. These galaxies will be hard to find. They've had most of their mass stripped by the gravity of the Milky Way's halo. But new telescopes like Vera Rubin should be able to spot them.

A Solar Gravitational Lens Telescope Is The Only Feasible Way To Get High Resolution Pictures Of A Habitable Exoplanet

Universe Today - Wed, 07/16/2025 - 7:27pm

Sometimes in order to support an idea, you first have to discredit alternative, competing ideas that could take resources away from the one you care about. In the scientific community, one of the most devastating ways you can do that is by making the other methods appear to be too expensive to be feasible, or, better yep, prove they wouldn’t work at all due to some fundamental limitation. That is what a recent paper by Dr. Slava Turyshev, the world’s most prominent proponent of a Solar Gravitational Lens (SGL) telescope mission, does. He examines how effective alternative telescope technologies would be at creating a 10x10 pixel map of an exoplanet about 32 light years away. Unsurprisingly, there’s only one that is able to do so without giant leaps and bounds in technology development - the SGL telescope.

Scientists Unlock Secrets of Matter Under Extreme Conditions

Universe Today - Wed, 07/16/2025 - 7:27pm

Scientists have recreated the universe's first moments by smashing atomic nuclei together at near-light speeds, generating temperatures 1,000 times hotter than the Sun's core and briefly forming the same "soup" of fundamental particles that existed microseconds after the Big Bang. In this groundbreaking research, heavy particles act like tiny cosmic detectives, moving through this primordial matter and revealing how the chaotic early universe transformed into the structured reality we see today. By understanding how these massive particles behave under the most extreme conditions imaginable, researchers are essentially reading the universe's origin story written in the language of fundamental physics.
