ESA’s Gaia satellite has looked beyond our galaxy and explored two nearby galaxies to reveal the stellar motions within them and how they will one day interact and collide with the Milky Way — with ...

New findings from the Gaia space telescope indicate the Milky Way may have cannibalized a small galaxy not too long ago, cosmically speaking. In fact, the last major collision between our galaxy and ...

Taken together, these studies illustrate that the Milky Way’s spiral arms are not just smooth arcs of stars, but dynamic, ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds ...

ESA’s Gaia mission has made a major breakthrough in unraveling the formation history of the Milky Way. Instead of forming alone, our galaxy merged with another large galaxy early in its life, around ...

Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The so-called "sleeping giant," named Gaia BH3, has a mass that ...

Our Milky Way galaxy never sits still: it rotates and wobbles. And now, data from ESA's Gaia space telescope reveal that our galaxy also has a giant wave rippling outwards from its centre. (Nanowerk ...

Star chemistry reveals two spiral arms and a faint bridge in the Milky Way, offering a clearer view of hidden structure in ...

A team led by Pasquale Panuzzo discovered Gaia BH3, a stellar-mass black hole approximately 33 times the mass of the Sun, using data from the Gaia observatory. Located 1,926 light-years from Earth in ...
