Atmospheric ozone and oxygen protect the biosphere of our planet against harmful ultraviolet radiation. In new research, astronomers modeled atmospheres...
Astronomers using ESO’s Very Large Telescope have captured the most detailed image yet of the young stellar object 244-440 and the bipolar jet associated...
Hercules X-1 is an X-ray binary system in which a neutron star is drawing material away from a Sun-like star. This neutron star’s accretion disk is unique...
Located 6,500 light-years away in the constellation of Taurus, the Crab Nebula and its pulsar formed in a supernova whose light reached Earth in July 1054.

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...
Observing magnetic star-planet interactions offers promise for determining the magnetic fields of exoplanets. Models of star-planet interactions predict...
The newly-observed stellar explosion, named AT2018cow, occurred approximately 180 million light-years away from Earth and belongs to a special class called...
The NASA/ESA Hubble Space Telescope have produced a beautiful image of the side-on spiral galaxy UGC 2890.
This Hubble image shows UGC 2890, a small spiral...
Astronomers have provided vital information in the global effort to understand GRB 221009A, one of the nearest and possibly the most-energetic gamma-ray...
In unveiling the nature of the first stars, the main astronomical clue is the elemental compositions of the second generation of stars, observed as extremely...
Gas giants, like other planets, form from protoplanetary disks of material around protostars. According to core accretion theory, they first form a core...
NASA has released a brilliant photo taken by the NASA/ESA Hubble Space Telescope of the globular cluster Messier 55.
This Hubble image shows a portion...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
Wolf-Rayet stars are in the process of casting off their outer layers, resulting in their characteristic halos of gas and dust. The new Webb images of...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
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.
An artist’s rendering of two brown dwarfs....
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...
