One hundred years ago, one star changed our view of the universe, proving that the Andromeda “nebula” was a galaxy like our Milky Way.
We are in the Milky Way. If you travelled on an extremely fast spaceship for more than two million years, you would reach our neighbour, the Andromeda galaxy. All other galaxies are even further away.
Extragalactic astrophysicists want to know how and why galaxies stop forming stars, change their shape and fade away. With help from citizen scientists, they’re figuring it out.
A titanic eruption in our neighbouring galaxy, Andromeda, has sent shockwaves through the astronomical community here on Earth. NASA’s Swift satellite detected a flood of gamma rays at 21:15 UTC yesterday…
Deep images of the sky reveal that the universe contains billions of galaxies. Some, such as our own Milky Way, are immense, containing hundreds of billions of stars. Most galaxies, however, are dwarfs…
After nearly a century of speculation, the Hubble Telescope can now predict with certainty: the titanic collision of the…
