Astronomers studying the globular star clusters orbiting the giant elliptical galaxy Centaurus A (NGC 5128) have stumbled upon a fascinating discovery -- the clusters are too massive.
If you ever wanted to take your starship on an intergalactic joyride, astrophysicists have got your back -- they've just created the most detailed cosmic 3-D map to date, spanning an mind-boggling distance of 2 billion light-years.
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.
A new study carried out by the ESO's Very Large Telescope and the NASA/ESA Hubble Space Telescope has revealed for the first time that dark matter may well interact with itself. Continue reading →
New research reveals just how invisible this stuff is, even to itself.
A dwarf galaxy orbiting the Milky Way is humming with gamma rays, leading astronomers to hypothesize that it could be filled with annihilating dark matter particles.
The hunt for the source of dark matter is one of the most hotly anticipated searches of our time and the Higgs boson might be able to light the way to a possible dark matter discovery.
It has long been assumed that the size of a supermassive black hole in a galaxy's core is intimately related to the number of stars that galaxy contains -- but it might not be that simple.
