Spiral galaxies are perhaps the most famous kind of galaxy, but sometimes they collide with other spirals and form elliptical galaxies. We see these three-dimensional egg-shaped blobs as two ...

Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate. Hubble was ...

A new astronomical instrument has had its first outing observing the velocities of colliding galaxies in the famous Stephan’s Quintet. It has revealed the rate at which one of these galaxies is ...

This breakthrough, the result of collaboration between powerful telescopes in Chile and an international team of scientists, sheds light on events in the early Universe that influenced star formation ...

It's explored our own solar system, studied the atmospheres of distant planets in search of signs of life and probed the farthest depths to find the very first stars and galaxies formed in the ...

"This discovery poses a challenge to the Lambda Cold Dark Matter model, which may struggle to account for the formation of such small, aligned groups of galaxies in isolated environments.

Our estimate of the number of stars and galaxies has steadily increased. In 1990, NASA launched the famous Hubble Space Telescope, sending it 353 miles out from the Earth. The photos from the ...

Light from the very distant and ancient galaxies is shifted towards very long wavelengths by the famous red shift of the expanding universe, as explored by Edwin P. Hubble himself. Light that was ...
