Leonardo Testi and team investigate the initial conditions for planet formation in this special astronomy focus ...

The galaxy cluster appears hotter and more mature than it should for its young age, challenging what we think we know about ...

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

How do you find a galaxy that never formed? The standard cosmological model predicts the existence of "failed" galaxies - clumps of dark matter that captured gas but never birthed a star. Because they ...

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, ...

Light takes time to travel through space. Because of this, the light we see from distant objects in the night sky represents ...

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.

An inexplicably hot, fast-growing cluster of galaxies in the early universe has scientists questioning theories of galactic ...

A potential new type of celestial object has all the makings of a normal small galaxy. It’s rich with the same hydrogen gas ...

Astronomers have captured the most detailed look yet at faraway galaxies at the peak of their youth, an active time when the adolescent galaxies were fervently producing new stars.

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

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