A new study based on Gaia satellite data reveals that dwarf galaxies around the Milky Way are likely transient and not as dark matter-rich as…
Gaia is creating an extraordinarily precise three-dimensional map of more than a billion stars throughout our Milky Way galaxy and beyond. It is mapping their…
ESA’s star-surveying Gaia mission has released a treasure trove of new data as part of its ‘focused product release’. As part of this data release,…
The location of the first two black holes discovered by ESA’s Gaia mission in the Milky Way. This map of our galaxy was also made…
Astronomers made a groundbreaking discovery by detecting a dormant stellar-mass black hole, the closest one to Earth yet found in the Milky Way. This first…

Astronomers using the International Gemini Observatory, operated by NSF’s NOIRLab, have discovered the closest-known black hole to Earth. This is the first unambiguous detection of…
One of the surprising discoveries coming out of Gaia data release 3, is that Gaia is able to detect starquakes – tiny motions on the…
This illustration is an artist’s impression of the thin, rocky debris disc discovered around the two Hyades white dwarfs. Rocky asteroids are thought to have…
This image shows the Milky Way as seen by Gaia. The squares represent the location of globular clusters, the triangles the location of satellite galaxies,…

[embedded content] The stars are constantly moving across the sky. Known as proper motion, this motion is imperceptible to the unaided eye but is being…
Gaia’s stellar motion for the next 400 thousand years. The stars are in constant motion. To the human eye this movement – known as proper…
Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution…
An artificial intelligence (AI) system analyzing data from the Gaia space telescope has identified more than 2,000 large protostars, young stars that are still forming…
