Using Chandra X-ray Observatory, astronomers detect X-ray emission from Uranus
One theory is that the Sun is behind the emission of the X-rays while another theory suggests that the rings are causing them.
Elusive neutron star remnants of famous Supernova 1987A finally found, scientists claim
In a decade, scientists expect to be able to see emissions from the pulsar better, to back their hypothesis with evidence.
NASA shares image of supernova remnant RCW 103 captured by Chandra
Data from Chandra, Swift and ESA's XMM-Newton confirmed that 1E 1613 has properties of a magnetar, making it only the 30th known magnetar.
Stunning images from NASA's Chandra X-ray Observatory show cosmic objects, stars, supernovas
While Chandra captures X-rays in the outflow of stellar explosions in some images, Hubble throws light on galaxies.
Hubble peers deep into the universe, finds 'missing link' evidence of mid-sized black hole
Black holes are extreme environments and are a testing ground for the laws of physics and our understanding of how the Universe works.
Clumpy-looking supernova remnant Tycho captured by NASA's Chandra X-ray Observatory
Did the explosion itself cause this clumpiness, or was it something that happened afterward?
Three black holes on a collision course imaged by multiple telescopes in a first
The observation is 'the best evidence yet' of a trio of supermassive black holes in apparently merging galaxies.
Strange green flash of light in 'Fireworks' galaxy picked up by NASA satellite
The flash could be a rare, more extreme case of matter falling into a black hole or neutron star.
NASA's Chandra spots 'Star Trek Enterprise' in colliding galaxy clusters far, far away
Trekkies can now rest easy in the know that there will always be an Enterprise (or 2) out there.
NASA's Chandra X-ray Observatory back in action after glitchy gyroscope woes
NASA expects observations from Chandra to resume as per usual by the end of this week.
Happy 15th birthday Spitzer! NASA's telescope completes fifteen years in space
NASA's Spitzer Telescope is the youngest member of the Great Observatory programme.
NASA deploys HaloSat to search for the "missing matter" that makes the universe
A NASA-sponsored CubeSat mission called HaloSat was deployed from the ISS on 13 July.
Merger of neutron star may have led to birth of the lowest mass black hole ever found reveal NASA scientists
If it is indeed a black hole, astronomers expect it to continue to become fainter that has recently been observed as the shock wave weakens.
NASA discovers rare neutron star outside of Milky Way and releases a stunning image of it
The neutron star discovered using data from NASA's Chandra X-ray Observatory is a rare variety that has both a low magnetic field and no stellar companion.
Sun-like stars tend to calm down after a violent youth allowing evolution of life, claims study
The findings published online in the journal Monthly Notices of the Royal Astronomical Society showed that older stars drop in activity quickly.
Nasa scientists discover cosmic tsunami of hot gas twice the size of the Milky Way
For the study, the researchers combined data from Nasa's Chandra X-ray Observatory with radio observations and computer simulations.
Nasa's Chandra X-Ray observatory discovers a brand new type of 'cataclysmic event'
A mysterious flash of X-rays probably resulting from a "completely new type of cataclysmic event" in space has been discovered by Nasa's Chandra X-ray Observatory, a study says.
Supermassive black hole sets record for duration and size of meal by eating a star for a decade: Nasa
Nasa astronomers have detected a giant black hole that ripped apart a star and then gorged on its remains for an unusually long time.
NASA's Chandra and India's GMRT discover a natural particle accelerator in deep space
At least one supermassive black hole next to a pair of colliding galaxies, Abell 3411 and Abell 3412 has resulted in a natural particle accelerator.
