Astronomers have been aware of cosmic vampires, dead stars that hungrily strip plasma from victim stars, for some time. New ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite ...

Farewell to Gaia, the Milky Way’s Cartographer After more than a decade of mapping the stars, the European spacecraft was shut down on Thursday. But its legacy lives on.

Astronomers bid an emotional farewell to Gaia, expressing their gratitude for its more than decade-long mission that gave us groundbreaking insights into our home galaxy, the Milky Way.

As Gaia continues to collect data, the ability of machine-learning models to handle the vast datasets quickly and sustainably makes them an essential tool for future astronomical research.

The European Space Agency's Milky Way-mapper Gaia has completed the sky-scanning phase of its mission, racking up more than 3 trillion observations of about 2 billion stars and other objects over ...

Gaia, Europe’s Milky Way–mapping spacecraft, shut down earlier this year. It was arguably the most important—and most overlooked—astronomy project of the 21st century ...

Astronomers using the Gaia space telescope have located two ancient streams of stars that helped the Milky Way galaxy grow and evolve more than 12 billion years ago.

The Gaia data show the speed at which more than 30 million Milky Way objects (mostly stars) are moving toward or away from us – the so-called radial velocity.
