Half of Milky Way's mass found in million-Kelvin gas cloud

Scientists have just discovered that the extreme drought bedeviling America's midsection is being caused by a gigantic halo of hot gas surrounding the Milky Way. Okay, okay... We're kidding about the cause of the drought – but not about that gas cloud, which is a few hundreds of thousands of light years in diameter, weighs …

Milky Way DOOMED to high-speed smash with Andromeda galaxy

Observations from the Hubble telescope have shown that the Milky Way is on a high-speed collision course with the nearby Andromeda galaxy and the two will merge into a new elliptical system. Andromeda, also called M31, is about the same mass as the Earth's Milky Way and similar in form. Although it's 2.5 million light years …

Earth receives picture postcard of Milky Way

Astronomers at the European Southern Observatory (ESO) have agreeably given we Earthlings a pretty good idea of what our Milky Way galaxy would look like, were we looking at it from the depths of intergalactic space. The ESO describes its snap of NGC 6744 as "almost a picture postcard" of our home, featuring "striking spiral …

Interstellar space 'full of Jupiter-size orphan planets'

A team of astronomers has identified a novel new kind of galactic wanderer - lone, Jupiter-sized planets expelled from forming solar systems and drifting in the empty void between the stars. The researchers, led by Takahiro Sumi of Japan's Osaka University, spotted 10 such free-floating "orphan planets" in data from a 2006-7 …
