NASA’s Kepler space telescope was responsible for the discovery of over 2,700 confirmed extrasolar planets, more than half of the total number of exoplanets...
As Enceladus orbits rapidly around Saturn with a period of only 1.37 Earth days, the ejected water vapor is spread along and around its orbit, forming...
Astronomers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is a...
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...

The newly-discovered planet has a radius of 1.03 Earth radii and a temperature between 27 and 127 degrees Celsius (81-261 degrees Fahrenheit), with the...
The gravitationally lensed Supernova (SN) Refsdal was discovered by University of Minnesota astronomer Patrick Kelly in 2014 in the field of MACS J1149.6+2223,...
Saturn’s ring system may well have formed when dinosaurs were still walking on the Earth, and will last only another few hundred million years at most,...
The new observations from the Near-Infrared Spectrograph (NIRSpec) aboard the NASA/ESA/CSA James Webb Space Telescope show that the main-belt comet 238P/Read...
AT2021lwx occurred nearly 8 billion years ago and was more than 10 times brighter than any known supernova explosion. The event was likely caused by the...
Using the NASA/ESA Hubble Space Telescope, astronomers have captured a striking new photo of the densely packed globular cluster NGC 6325.

Astronomers at Newcastle University and Colby College have developed a new technique to determine how likely it is that two galaxies are very close together...
Gliese 1214b is a so-called mini-Neptune, a smaller, denser version of Neptune that consists of a rocky core surrounded by a thick blanket of gas.
This...
The Hubble team has released a beautiful new image of two massive galaxies, NGC 545 and NGC 547, collectively known as Arp 308.
