Hubble’s scientific bounty has benefited a wide range of astronomical and astrophysical fields, including the study of planets, moons and small icy bodies in the outer solar system and the cosmological history of the universe. Here’s a look at a few of Hubble’s greatest hits.
New research reveals just how invisible this stuff is, even to itself.
Tonight at 7 p.m., live via Discovery News, we're streaming special public lecture by cosmologist Kendrick Smith, of the Perimeter Institute for Theoretical Physics, in Ontario, Canada.
Scientists studying more than 140,000 extremely bright galaxies have calculated the expansion of the universe with unprecedented accuracy.
A space station particle detector is closing in on a comic ray mystery.
The mysterious dark energy that's driving the universe's accelerated expansion may have its roots in the background 'vacuum energy' that pervades all of the cosmos.
A new experiment buried deep underground has proven itself to be the most sensitive dark-matter detector ever built -- but the first results from the high-tech instrument have turned up empty in its search for elusive dark matter.
A trio of relatively young astronomers won the prestigious Nobel Prize for Physics today, not for solving a problem, but for making an observation: our universe is expanding faster now than it did in the past.
