Astronomers using ESO’s VLT Survey Telescope have produced a spectacularly detailed image of the emission nebula IC 4701.
This OmegaCAM/VST image shows...
It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed...
The members of the LP 413-53AB system are so close that it takes just 17 hours to revolve around each other.

Supernova (SN) 185 occurred in 185 CE in the direction of Alpha Centauri, between the constellations of Circinus and Centaurus, and remained visible to...
X3a is approximately 10 times larger than the Sun, 15 times as massive, and is only several tens of thousands of years old.
Multiwavelength detection of...
An elongated dust and gas feature named X7 has a mass of about 50 Earth masses and is on an orbital path around Sagittarius A*, the supermassive black...
Dr. Lokesh Mishra and his colleagues from the University of Bern and Geneva Observatory propose that the space of planetary system architectures be partitioned...
The Andromeda galaxy (Messier 31), which is located 2.5 million light-years away, is the Milky Way’s nearest large galactic neighbor. By measuring the...
In November 2019, the nearby single, isolated white dwarf LAWD 37 aligned closely with a distant background source and caused a so-called microlensing...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured the reflectance spectrum of the double-ringed centaur 10199 Chariklo and observed...
Magnetars are a special subset of the isolated neutron star family, with X-ray and radio emission mainly powered by the decay of their immense magnetic...
The second data release of the Dark Energy Camera Plane Survey (DECaPS2), which took two years to complete and produced more than 10 terabytes of data...
