Study led by University of Bonn finds galaxy clusters contain about twice as much normal matter as previously estimated, based on recalculated stellar populations and survey data.

Scientists discovered a distant jellyfish galaxy with star-forming "tails" stretching back 8.5 billion years.

When you gaze up at the night sky, you’re looking back in time. Light from the stars takes years, sometimes millennia, to ...

It was based on observations from the James Webb Space Telescope, Gemini North Telescope, and NASA/ESA Hubble Space Telescope ...

Using data from the Hubble Space Telescope, ESA’s Euclid space observatory, and Hawaii’s Subaru Telescope, the researchers discovered faint light emitting around the clusters. That light was clear ...

An international collaboration using the Low Frequency Array (LOFAR) has published an exceptionally detailed radio sky map, ...

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

A team of astronomers has identified an extremely faint galaxy called CDG-2, located roughly 300 million light-years from Earth, where an estimated 99% of its total mass is made of invisible dark ...

For decades, astronomers knew something was wrong — about 40% of the universe’s visible matter was missing. Galaxies, ...

A multifractal spectrum called a weighted Cantor set model can describe how galaxies cluster, which is similar to other ...
