Astronomers using NASA’s Chandra X-ray Observatory have detected stable titanium, along with chromium and iron, blasting out from the center of the supernova...
As part of the Clusters Hiding in Plain Sight (CHiPS) survey, astronomers have discovered three new galaxy cluster candidates and confirmed two of them:...
Uranus, the seventh planet from the Sun, and its ring system appear to mainly produce X-ray emission by scattering solar X-rays, but some may also come...
The source of the 160,000-light-year-long jet of particles is PSO J352.4034-15.3373 (PJ352-15 for short), a rapidly growing supermassive black hole, or...
Supernova 1987A (SN 1987A) was first observed on February 23, 1987 in a nearby dwarf galaxy, the Large Magellanic Cloud, some 164,000 light-years away....
Sagittarius A East (Sgr A East), a supernova remnant located strikingly close to the central supermassive black hole of our Milky Way Galaxy, resulted...
Astronomers using NASA’s Chandra X-ray Observatory have studied Swift J1818.0-1607, a new magnetar (a type of neutron star with an extremely powerful...
Astronomers using NASA’s Chandra X-ray Observatory are searching for signs of a recoiling black hole in the core of A2261-BCG, the most massive and brightest...
Astronomers using NASA’s Chandra X-ray Observatory have spotted a bubble of ultrahot gas at the center of a planetary nebula called IC 4593.
This composite...
Barnard’s star, a 10-billion-year-old red dwarf just 6 light-years from Earth, is still very active and potentially destructive for the atmospheres of...
In 2017, astronomers detected a gravitational-wave signal, designated GW170817, from the merger of two neutron stars. And since the detection, they have...
Astronomers using NASA’s Chandra X-ray Observatory have detected an extragalactic candidate planet circling a binary system in Messier 51 (also known...
Around five years ago, NASA’s Fermi Gamma-ray Space Telescope detected high-energy gamma rays coming from TXS 0128+554, an elliptical galaxy located...
Astronomers using NASA’s Chandra X-ray Observatory have observed a pair of relativistic jets blasting away from a black hole in the binary system MAXI...
Astronomers using ESA’s XMM-Newton and NASA’s Chandra X-ray observatories have observed a 3-million-light-year-long bridge of hot gas linking two unequal...
Professor Andrew King from the University of Leicester has shown that periodic X-ray eruptions from a galaxy called GSN 069 could result from the core...
Space-based X-ray observations of hundreds of galaxy clusters suggest that the Universe may be different depending on which way astronomers look. The study...
Astronomers using the 8.2-m Subaru Telescope report the first unambiguous detection of a relativistic jet — a beam of charged particles that travels...
Astrophysicists using NASA’s Chandra X-ray Observatory have looked for signs of an as-yet undetected particle predicted by string theory, a set of models...
