The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from...
SGR 0501+4516 is the likeliest candidate in our Milky Way Galaxy for a magnetar that was not born in a supernova explosion as initially predicted; the...
The mass of the supermassive black hole in the center of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, is about 600,000 solar...
The candidate planetary system, detected with the microlensing method, is thought to move at least 540 km per second (1.2 million mph).
An artist’s impression...
Launched on December 19, 2013, the fuel tank of ESA’s star-mapping satellite Gaia is now approaching empty, but this is far from the end of the mission....
Binary asteroids have attracted the attention of the scientific community due to their interesting properties and the significant impact they have on our...
Using data from ESA’s Gaia mission, astronomers have found a large number of metal-poor stars older than 13 billion years on orbits similar to that of...
This discovery was made possible by ESA’s Gaia spacecraft, which is mapping more than a billion stars throughout the Milky Way Galaxy and beyond, tracking...
Astronomers at MIT have discovered thee extremely ancient stars in the Milky Way’s halo, a cloud of stars that envelopes the entire main Galactic disk....
Using data from ESA’s Gaia mission, astronomers have discovered a nearby binary system composed of a giant star orbiting a dormant black hole of of stellar...
Dubbed Shakti and Shiva, the newly-identified structures are between 12 and billion years old — so ancient they likely formed before even the oldest...
The new map, dubbed Quaia, includes around 1,295,502 quasars from across the visible Universe and could help astronomers better understand the properties...
Our Sun lies within 300 parsecs (around 1,000 light-years) of the 2,700-parsec- (around 9,000-light-year-) long sinusoidal chain of dense gas clouds known...
In a new study, astronomers from Yale University and MIT examined the joint spin-orbit and orbit-orbit distribution for exoplanets residing in binary and...
Technosignatures are any measurable property that may provide evidence of extraterrestrial technology. The search for extraterrestrial intelligence (SETI)...
Be-type stars make up almost 20% of the B star population, and are rapidly rotating stars surrounded by a disk. Although these stars have been known for...
A team of U.S. astronomers has discovered that two-thirds of the planets around M dwarfs (red dwarf stars) could be roasted by extreme tidal forces, sterilizing...
Using the NASA/ESA Hubble Space Telescope and other space and ground-based observatories, astronomers have discovered SDSS J0749+2255, a closely bound...
The newly-discovered dormant black hole, named Gaia BH2, is orbited by a red giant star, and has a mass of 8.9 solar masses.
The location of Gaia BH2 and...
