The photos capture Mars passing below two objects known as the Lagoon and Trifid nebulas, both in the constellation Sagittarius.
An extraordinary amount of ultraviolet light appears to be missing from the universe, scientists have found.
Scientists studying more than 140,000 extremely bright galaxies have calculated the expansion of the universe with unprecedented accuracy.
Astronomers have added an ultraviolet perspective to an ultra-deep field view of the universe taken by the Hubble Space Telescope over the past decade. Continue reading →
What happens when two neutron stars collide? Using a sophisticated computer simulation, NASA scientists have visualized this violent scenario in awesome degenerate-matter-crushing detail. Continue reading →
After 3 months of number-crunching, 8,000 computer processors working in parallel have recreated the evolution of our Universe in unprecedented detail. Continue reading →
It's a big, big universe out there and the Hubble Space Telescope bores a hole over halfway out into it with this image, showing a gathering of galaxies near and far. Continue reading →
Last month's BICEP2 discovery of gravitational waves is compelling evidence for the inflationary period just after the Big Bang. But what if there's another explanation? Continue reading →
