Are the planets of the solar system sprouting invisible dark matter 'hairs'? If so, does this indicate an interplanetary trend of dark matter 'beards'?
While measuring the speed of stars whirling around a nearby dwarf galaxy, astronomers have realized that a reservoir of dark matter may be lurking within.
Shimmering deep inside a cosmic supervoid is MCG+01-02-015, a pristine galaxy that is the undisputed galactic loner of the universe.
Scientists are taking initial steps in a long-term effort to learn as much as they can about gravitational waves -- mysterious undulations in the fabric of space-time that have so far evaded clear detection.
Our universe is actually really simple, it's just our cosmological theories that are getting needlessly complex, argues one of the world's leading theoretical physicists.
The great cosmologist Bruce Springsteen once sang "everything dies, baby, that's a fact," but does that assertion include the little universe we call home? Julian takes us through the current theories on what will happen to our space and time.
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.
