Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

Take a journey through the Milky Way galaxy, exploring the wonders of our solar system and the distant stars that illuminate the night sky. The Milky Way is home to over 100 billion stars, each with ...

Astrophysicists suggest our galaxy may lie inside a "cosmic void" - offering a new explanation for the universe’s conflicting ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, ...

We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

Fresh evidence claims that the Earth and the surrounding galaxy are suspended inside a cosmic void based on echoes from the ...

When looking up at the sky, you might think galaxies have always looked the way they do today. But a new study from Princeton ...

Astronomers using the Green Bank Telescope spotted surprisingly cold, dense hydrogen clouds embedded inside the Milky Way’s ...

Hopkins and Lintott are two of the six authors of a new paper that uses the new model to trace the origin of Comet 3I/ATLAS, and it appears to be coming from a completely different region of the ...

Astronomers have turned the Atacama Large Millimeter/submillimeter Array (ALMA) into a time machine to peer back in cosmic time to 1 billion years after the Big Bang.

Particular stars called Cepheid variables allow astronomers to determine distance, and Hubble spotted one of these within M31.

Galaxies, including the Milky Way, grow from thick, turbulent disks into layered structures. JWST’s images show this process ...
