All good things come to an end and the European Space Agency’s Herschel Space Observatory mission is no exception. After more than three years in orbit, the most powerful infrared telescope ever flown in space has ceased scientific operations after the last of the liquid helium used to supercool its instruments ran out...

The European Space Agency says its flagship Herschel telescope, the most powerful infrared observatory ever put in orbit, has run out of coolant and stopped working.

New telescopic findings help shed light on a black hole physics mystery. Nothing can escape a black hole, even light, because to wrench away from its titanic gravitational pull, you’d have to move faster than light is capable of traveling. And nothing can do that, as far as anyone knows. As matter falls into a black hole’s gaping maw, it superheats to millions of degrees,...

The Hubble Space Telescope has been in orbit for 23 years and, to celebrate this milestone, the space telescope has revisited the famous Horsehead Nebula in the constellation of Orion.

Chomp chomp, guuulp. Later this year, the supermassive black hole at the center of the Milky Way will dine on a small passing cloud of gas, which wandered too close and is now spiraling toward the black hole’s maw. But that may only be a first course, according to new observations. The Herschel space telescope spotted a vast amount of surprisingly hot molecular gas near the...

The Kepler space telescope has already found thousands of exoplanets orbiting other stars, and now the next space telescope to join the search has been announced.The Transiting Exoplanet Survey Satellite (TESS), a project of MIT, was selected by...

Nasa may have discovered the youngest black hole in the Milky Way. The agency's Chandra X-ray Observatory caught the remnant galaxy W49B with what appears to be a black hole at its centre. The "highly distorted" cloud of gas and material pictured by the telescope is all that's left of a supernova which occurred about 1,000 years ago (as seen from Earth). The remnant is...

A black hole and an ill-fated red dwarf star make for the fastest binary orbit ever observed, with the star traveling at a staggering two million kilometers per hour. Continue reading →

A high-tech NASA telescope in orbit escaped a potentially disastrous collision with a Soviet-era Russian spy satellite this month in a close call that highlights the growing threat of orbital debris around Earth. NASA's $690 million Fermi
