“The Euclid data clearly confirm the presence of the extremely faint, diffuse light of CDG-2, revealing the galaxy behind the ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass.

Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

Using the Hubble Space Telescope, astronomers have discovered what seems to be a galaxy that is the most heavily dominated by ...

Astronomers discover galaxy CDG-2 that's 99% dark matter using Hubble, Euclid, and Subaru telescopes working together to detect this cosmic ghost 300 million light-years away.

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

A tight clump of four star clusters sits in the Perseus galaxy cluster, and at first glance it looks like nothing special. No ...

Deep beneath the planet’s surface at the Sanford Underground Research Facility in South Dakota, scientists are waiting for something that may never happen – the interaction of weakly interacting ...

New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the ...

One third of the galaxy’s entire stellar output is locked away in just a few dense balls of stars. The rest is just a thin, cold “field” of stars barely clinging to existence. It is, for all intents ...
