Chandra's wandering black hole

Stripped of its galaxy, this black hole is wandering naked in the cosmos

Boffins analysing old Chandra x-ray telescope data have spotted a rarity indeed: an X-ray source that seems to be a black hole, but without a galaxy to surround it. At an estimated 100,000 times the mass of the sun, the black hole in question – at the edge of lenticular galaxy SDSS J141711.07+522540.8, about 4.5 billion light …

Pluto's emitting X-rays, and NASA doesn't quite know how

The Chandra space telescope has spotted X-rays emanating from Pluto. What? That's “cold, dead, former planet Pluto with no magnetic field”, to most of us: orbiting between 4.4 billion km and 7.4 billion km from the sun out in the Kuiper belt, with no way to generate heat. That Pluto. Since we don't suppose the former-planet …

Mystery black hole hides by curbing its appetite

A well-known radio source has turned out not to be the galaxy it's been classified as for 20 years, but a surprisingly quiet black hole. The discovery is causing a bit of buzz among astrophysicists because it suggests there could be thousands or millions more “covert” black holes out there waiting to be discovered. It took …

Supernova bubble clocked at 19,000,000 km/h

Astronomers have produced a fetching animation of the inexorable outwards expansion of the remains of the Tycho Type Ia supernova - a white dwarf in a binary star system which went bang in spectacular fashion back in 1572. The explosion was so bright it was visible from Earth during the day, even at a distance of some 10,000 …

SPLAT! STAR THWACKED, GUTS flung into space at 15 per cent of LIGHTSPEED

In perhaps the most violent punch that has ever been witnessed by humanity, a speeding pulsar has smashed right through a disk of matter bulging from the middle of a hefty star and blown a massive chunk of it guts into interstellar space at a significant fraction of light speed. That's according to top space boffins peering …

'Sterile neutrinos' re-ignite 'we found dark-stuff' debate

Astro-physicists remain cautiously (around media) excited (among themselves) about an unexpected X-ray signal discovered in a survey of galactic clusters. Having first put their findings in the public sphere in March, as reported by The Register at the time, the work has now passed peer review to hit the presses in the …

GIANT FLIP-FLOP IN SPACE switches between X-ray and radio emissions

Video An unusual pairing of objects called a “low mass X-ray binary” has been spotted by astronomers in which a pulsar shifts between emitting fast radio pulses and X-rays. Dubbed the “Transformer Pulsar” in some quarters and the “missing link” pulsar in others, the 18,000-light-year-distant binary in the M28 cluster works like this …

KABOOOM! Space-faring dwarf's galactic pile-up snapped by X-ray boffins

Pics Astronomers have spotted a huge collision between a plucky little dwarf galaxy and a massive spiral rival that goes by the snappy name of NGC 1232. NASA stargazers using the orbiting Chandra X-ray Observatory were alerted to the intergalactic pile-up after spotting a cloud of super-heated gas in the huge spiral galaxy, which …

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 …

Undead galaxy cluster spews 700 zombie baby stars A YEAR

Astroboffins have spotted a galaxy cluster that's breaking all the cosmic rules, including coming back to life to spawn stars at an enormous rate. The Phoenix cluster is spewing out the celestial bodies at the highest rate ever observed for the middle of a galaxy cluster; it's the most powerful producer of X-rays of any known …

Crazy old black hole's X-ray ultra-belch makes galaxy blush

A powerful blast of X-rays - equivalent to the energy emitted by a MILLION Suns - has been fired out of a black hole in the spiral galaxy M83, lighting up the space around it.

Chandra tags ancient black holes

Black holes may have been all over the early universe, according to new findings announced by NASA. A starfield gathered by its Chandra X-ray observatory, known as Chandra Deep Field South (CDFS), and analyzed in conjunction with the Hubble Space Telescope, has turned up a mass of previously-undiscovered black holes from when …

Ancient pulsar still radiating like a young 'un

NASA's Chandra X-ray Observatory has detected what the agency describes as a "surprisingly active" ancient pulsar - the oldest such body ever spied in the X-ray band and still radiating after around 200m years. PSR J0108-1431, aka J0108 for those in a hurry, lies at around 770 light-years from Earth. It's an "isolated" pulsar …

Scientists discover galaxy's youngest supernova

Where have all the Milky Way's supernovas gone? Contrary to what would seem a basic survival instinct, many astronomers are positively keen to get more catastrophic, solar-system-busting explosions in our home galaxy. But until recently, a good Jerry Bruckheimer space opera hasn't appeared to reach Earth since the seventeenth …
