Webb discovered an early cosmic boom of "red monster" galaxies, surprising even seasoned researchers who thought they knew ...

Intriguingly, ultralight dark matter might be able to turn into photons (light) — and it's through this process that the research team hopes to eradicate molecular hydrogen and allow gas clouds to ...

Everything we visualize about space, including stars, planets, gases, and even galaxies, make up just a small fraction of the ...

Here are a few key lines of evidence for dark matter: 1. Galaxy rotation curves When astronomers measure how fast stars orbit the centers of galaxies, they find something strange. The stars at the ...

In such an event, the gas separates from the dark matter, and subsequent star formation in the expelled gas forms one or more dark-matter-free galaxies. Previous research found that the two ...

"This would appear as a brightening of stars in stellar surveys like OGLE. The effect we identified is similar—visible light can be scattered or absorbed by the dark matter compact objects ...

Although we’re still searching for observational evidence of dark matter, scientists haven’t been able to account for about 15 percent of the regular matter in the universe with just stars ...

First spotted in 2024, FCC 224 is a dwarf galaxy that boasts a dozen luminous, tightly bound clusters of stars — an unusually rich population for its size, typically seen in larger, dark-matter ...
