First evidence of galaxy metamorphosis detected
Many galaxies in the universe have undergone a dramatic transformation from flat discs into spherical shapes over the past 8 billion years or so, say researchers.

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.

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.

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.

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.

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.

Astronomers Find A Supermassive Black Hole In A Tiny Galaxy
An international team of astronomers have announced that they’ve discovered a supermassive black hole at the center of the galaxy M60-UCD1. This is the smallest known galaxy to have a supermassive black hole.

Milky Way Punier Than We Thought
Looks like our home galaxy, the Milky Way, has gone on the ultimate weight-loss program, according to astronomers. According to a new supercomputer simulation, it turns out that the entire mass of our Milky Way galaxy is about half that of the great Andromeda galaxy, our nearest neighbouring spiral galaxy some 2.6 million light-years away from us. Astronomers had long thought the galaxies were twins.

Why Aliens and Volcanoes Go Together
The novelist William Golding suggested to James Lovelock that he name his now-famous hypothesis after the Greek goddess of the Earth, Gaia. It was a good fit: Lovelock believed that the living and inanimate parts of the Earth formed a single, interacting, and self-regulating system. Lovelock’s work grew, in part, out of research he had done for NASA, and published in a 1965 Nature paper, about the signs of life we might look for on other planets.

Nearly Every Star Hosts at Least One Alien Planet
The vast majority of stars in our Milky Way galaxy host planets, many of which may be capable of supporting life as we know it, a new study suggests. Astronomers have detected eight new exoplanet candidates circling nearby red dwarf stars, which make up at least 75 percent of the galaxy's 100 billion or so stars.

Here's why the Europa mission is real, and could very well happen
How is this possible? Especially in a time of very tight budgets? After all any credible mission to fly a large robotic mission to Europa, land and possibly penetrate the ice to see if life is indeed there would be incredibly expensive. And NASA has said it can afford no more Flagship-class science missions.

Could Some Alien Worlds Be More Habitable Than Earth?
Planet hunters have always been keen to find Earth's twin, but an astrobiology team now suggests that "superhabitable" planets may be even better places to look for alien life.
