Astronomers Spot a High-Speed Star That May Carry a Planet With It
A celestial object, possibly a small star with a massive exoplanet, has been observed moving through the Milky Way at an extraordinary speed of over 1.2 million mph. The discovery…
T Tauri’s Great Dimming: Astronomers Study Young Star’s Potential Disappearance
The bright protostar T Tauri, situated 471 light-years away in the Taurus constellation, is expected to vanish from view for decades. This dimming phenomenon, triggered by a thick disk of…
Astronomers Seek Binary Supermassive Black Holes in Galactic Centers
Supermassive black holes are believed to exist at the centre of most galaxies, including our Milky Way. However, in certain cases, two such black holes are thought to orbit one…
Astronomers Uncover New Details of CIZA0107 Galaxy Cluster Merger with VLA
An international team of astronomers has studied a nearby galaxy cluster merger, offering new insights into the processes of galactic collisions. Observations of CIZA J0107.7+5408, a post-core passage binary cluster…
Astronomers witness the in situ spheroid formation in distant submillimetre-bright galaxies
An international team of researchers including The University of Tokyo Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) has found evidence showing that old elliptical…
How astronomers are using pulsars to observe evidence of dark matter
Tantalising evidence of potential dark matter objects has been detected with the help of the Universe’s ‘timekeepers’. These pulsars — neutron stars which rotate and emit lighthouse-like beams of radio…
A hidden treasure in the Milky Way — Astronomers uncover ultrabright x-ray source
X-ray binaries are intriguing systems consisting of two celestial bodies: a normal star and a compact, dead object such as a black hole or a neutron star that sucks material…
Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior
At the heart of a far-off galaxy, a supermassive black hole appears to have had a case of the hiccups. Astronomers from MIT, Italy, the Czech Republic, and elsewhere have…
Astronomers spot oldest ‘dead’ galaxy yet observed
A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, an international team of astronomers…
Astronomers detect seismic ripples in ancient galactic disk
A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old,…
