The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calculated from different models of the galaxy cluster whose immense .
NGC 1333 is a star cluster populated with many young stars that are less than 2 million years old, a blink of an eye in astronomical terms for stars like the Sun expected to burn for billions of years.
Hubble Maps the Temperature and Water Vapor on an Extreme Exoplanet
A super-hot planet 260 light-years from Earth is showing signs of water vapor in its atmosphere, despite scorching temperatures that are hot enough to melt steel, according to the best weather map ever created of an alien world.
Smiley face This photo taken of the galaxy cluster SDSS by the Hubble Space Telescope appears to show a smiling face at the center. The two eyes are bright galaxies and the smile lines are arcs caused by an effect known as strong gravitational lensing.
