Using data from the James Webb Space Telescope, astronomers traced how Milky Way–like galaxies formed and changed over time.

Measuring the energy of hot gas within a remote group of galaxies reinforces the importance of giant black holes in forming ...

'This galaxy was developing bars 2 billion years after the birth of the universe,' says a researcher.

Research led by Daniel Ivanov, a physics and astronomy graduate student in the Kenneth P. Dietrich School of Arts and Sciences at Pitt, uncovered a contender for one of the earliest observed spiral ...

Astronomers have discovered a rare starless galaxy-like cloud known as a RELHIC, providing the strongest evidence yet for a cornerstone prediction of the Lambda CDM model: that many small dark matter ...

Cloud-9 entered the picture in 2023, when astronomers using the Five-hundred-meter Aperture Spherical Telescope (FAST) in ...

An object spotted in deep space is the strongest candidate yet for a galaxy arrested during early development.

Astronomers have identified Cloud 9, a nearby dark matter halo filled with gas but no stars. The discovery supports key predictions about how galaxies form and why some never do.
