NASA's Hubble Space Telescope has taken the deepest view yet of the gassy, dusty, Tarantula Nebula, located some 160,000 light-years away.
An expected collision between a gas cloud and a supermassive black hole at the center of our Milky Way will help us better understand the evolution of the entire galaxy, say scientists.
Astronomers say they've spotted a new class of stars speeding to the galactic exit, but not flung out from the galactic core by a black hole. Their origin and the reason for their haste are mysteries.
Hand of God: NASA's Nuclear Spectroscopic Telescope Array has spotted a pulsar wind nebula that resembles a gigantic ethereal right hand.
Aurora Borealis: A powerful solar flare is shaking up the Earth's magnetic field, producing a light show in the sky for much of North America.
A major solar flare has prompted the spaceflight company Orbital Sciences to delay its resupply mission to the International Space Station.
The Gemini Planet Imager (GPI), an intricate astronomical instrument the size of a small car can see planets a million times fainter than their parent stars. The technology is a step closer to finding a habitable planet beyond our solar system.
Scientists looking for clues into how supermassive black holes form might have found some at the heart of dwarf galaxies. These middleweight black holes could be 'seeds' of the bigger ones.
NASA's Hubble Space Telescope has snapped images of a cluster of galaxies some 3.5 billion miles away, whose mass helps magnify galaxies 12 billion miles away.
The atmosphere of a brown dwarf 6.5 light-years from Earth rains molten iron and has hurricane-force winds. Here's how astronomers know that – and why that information is useful.
