Einstein's theory of general relativity predicted that the universe wasn't static, but rather expanding. This was a revolutionary idea at the time, and it wasn't until astronomer Edwin Hubble's ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is ...

Hubble’s updated view of NGC 3370, richer in light and detail than ever before, deepens our understanding of both the galaxy and the cosmos itself. This new Hubble Picture of the Week highlights a ...

In October 1923, Edwin Hubble utilized the 100-inch Hooker telescope to photograph the Andromeda Nebula, identifying a variable star within it. Hubble applied the known period-luminosity relationship ...

After a century of observations spanning the breadth of the cosmos and theoretical insights that push humanity's vision of the universe to its utmost limits, we can finally, confidently say that the ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

The most distant galaxies in this deep field image from the James Webb Space Telescope appear as small, faint dots—and are receding from us faster than the speed of light due to cosmic expansion. If ...

Hubble captured a breathtaking view of NGC 6000, a spiral galaxy where blue newborn stars shine beside golden, aging ones. The image also reveals traces of ancient supernovae still glowing faintly ...

The Hubble Space Telescope, a cornerstone of modern astronomy, has been providing breathtaking images and invaluable data for over three decades. As a collaboration between NASA and the European Space ...

The UC Davis department of physics and astronomy, together with the College of Letters and Science, will host a free reception and public lecture on Tuesday, Nov. 4 from 6 to 8:30 p.m. at the UC Davis ...

Astronomers from the International Centre of Radio Astronomy Research (ICRAR) have created the largest low-frequency radio ...
