However, it wasn’t until the work of Edwin Hubble (for which the famous telescope is named) that astronomers realized objects like Messier 83 are actually other galaxies outside the Milky Way.

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 ...

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 ...

When you point a telescope toward the Pegasus constellation, you can discover a scene where the Milky Way stars and distant ...

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 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 ...

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 ...

Current models suggest that these massive structures form as clumps of dark matter and the galaxies that form within them are pulled together by gravity to form groups of dozens of galaxies ...
