When we look up at the night sky, most of us see stars, most of which are relatively close: less than 5,000 light-years from ...

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology.

The reason that teams on multiple telescopes in all different directions could hear this noise is that this annoying sound was actually the Cosmic Microwave Background (CMB)—radiation left over from ...

In the direction of Pisces, approximately 560 million light-years from Earth, scientists have discovered a particularly ...

This powerful side-by-side comparison shows just how bright a star explosion is. Recently, the Hubble Space Telescope captured a before-and-after image of a star exploding brightly. With the images ...

The Hubble Space Telescope is one of the most famous scientific instruments that has ever existed. It’s given the world an unfathomable amount of data and allowed for never-before-imagined exploration ...

As the sun sets, the Summer Triangle is straight overhead. To the north, the Big Dipper dominates as always, its cup sitting nearly parallel to the horizon late in the evening. Malan is astronomy ...

Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars in the Milky Way’s stellar halo. The most distant of these stars is more than a million light years from Earth, ...

A comet known as 3I/ATLAS made news when it was confirmed to be the 3rd-ever object observed to have originated outside Earth's solar system. Though the object poses no threat to Earth, astronomers ...
