But Hubble's about far more than just pretty pictures. The mission has gathered dozens of terabytes of data over the decades, providing key insights into the universe, from objects as close asthe moonto the most remote galaxies, with observations of supernovas and nebulas in between. Here we...

The shear force of the matter rubbing together releases a tremendous amount of energy, causing a supernova explosion. Supernovas are some of the most energetic phenomena in the universe, a fitting end to the majestic life of a star. Michael Anissimov Michael is a longtime contributor who s...
NASA's Chandra X-ray Observatory has taken space-based images of the universe in X-ray light since 1999. See spectacular photos by the Chandra space telescope here.

A planetary nebula is a phenomenon that occurs when a small to medium-sized star approaches the end of its life cycle. While very large stars end their lives in an explosion of light called asupernova, smaller stars fade out more gradually as gases and radiation exit their core. The first...
Scientists uncover hydrogen-poor stars behind spectacular supernovas, addressing a longstanding cosmic mystery, marking a breakthrough in understanding stellar evolution and cosmic phenomena.

expanding at a rate of 4,000-6,000 km/s. It has a temperature of about 50 million degrees Fahrenheit. The explosion of Cassiopeia A occurred at an estimated distance of 11,000 years from our planet. The first light of the supernova is believed to have reached Earth about 300 years ...
Stellar nucleosynthesis is a process in which most of the elements on the periodic table are created. The way that nucleosynthesis...
