Is this ET? Mystery of strange radio bursts from space
Mysterious radio wave flashes from far outside the galaxy are proving tough for astronomers to explain. Is it pulsars? A spy satellite? Or an alien message? Bursts of radio waves flashing across the sky seem to follow a mathematical pattern. If the pattern is real, either some strange celestial physics is going on, or the bursts are artificial, produced by human – or alien – technology.

Our sun came late to the Milky Way's star-birth party
Astronomers compiled a story of our Milky Way's growth by studying galaxies similar in mass to our galaxy, found in deep surveys of the universe. Stretching back more than 10 billion years, the census contains nearly 2,000 snapshots of Milky Way-like galaxies.

NASA’s Hubble Finds Pluto’s Moons Tumbling in Absolute Chaos
If you lived on one of Pluto’s moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA’s Hubble Space Telescope shows that two of Pluto’s moons, Nix and Hydra, wobble unpredictably.

Here be dragons: the supermassive black hole that's growing impossibly fast
“Here be dragons” was a phrase once used on ancient maps, often accompanied by mythical sketches, to highlight an unexplored or potentially dangerous area. Astronomers might want to borrow this warning to label the centre of galaxies, which contain supermassive black holes. There’s a lot we don’t know about these monsters – and scientists have just found one that even defies the laws that are meant to govern its growth.

Spactacular Centaurus A galaxy
Centaurus A, also known as NGC 5128, is well known for its dramatic dusty lanes of dark material. Hubble’s new observations, using its most advanced instrument, the Wide Field Camera 3, are the most detailed ever made of this galaxy. They have been combined here in a multi-wavelength image which reveals never-before-seen detail in the dusty portion of the galaxy.

What It Looks Like To Leave Our Solar System At The Speed Of Light
There is no better way to grasp the enormity of space than hitching a ride on a photon from the Sun. Take an hour, and just let the sheer vastness of our universe sink in. And this video stops at Jupiter.

Too big for its boots: black hole is 30 times expected size
The central supermassive black hole of a recently discovered galaxy is far larger than should be possible, according to current theories of galactic evolution. New work, carried out by astronomers at Keele University and the University of Central Lancashire, shows that the black hole is much more massive than it should be, compared to the mass of the galaxy around it. The scientists publish their results in a paper...

The Galaxy That Got Too Big
We can’t help ourselves—we’re crazy about big things. We’ll venture miles out of our way to see the world’s “largest” rifle (33.3 feet long; Ishpeming, Michigan), high-heeled shoe (6.1 feet tall; New York City), or ball of twine (7.8 million feet unraveled; Cawker City, Kansas).

A 'dead' galaxy full of dark matter is lurking close to home
At the edge of the Milky Way, there's a small galaxy called Triangulum II. It has just 1,000 stars, compared to the 100 billion estimated in our own galaxy, and its days of star formation are over, leaving it "dead." But Triangulum II may have a dark secret - one that makes it the most interesting ghost town in space.

Scientists get first glimpse of black hole eating star, ejecting high-speed flare
An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light. The finding reported Thursday in the journal Science tracks the star—about the size of our sun—as it shifts from its customary path, slips into the gravitational pull of a supermassive black hole and is sucked in, said Sjoert van Velzen, a Hubble fellow at Johns Hopkins.
