When a massive star runs out of fuel and approaches the end of its life, it explodes in a huge outpouring of energy called a supernova. These events can be so bright that they outshine entire galaxies ...

This NASA/ESA Hubble Space Telescope image features the galaxy LEDA 857074, located in the constellation Eridanus. LEDA 857074 is a barred spiral galaxy, with partially broken spiral arms. The image ...

Rich with detail, the spiral galaxy NGC 1309 shines in this NASA/ESA Hubble Space Telescope image. NGC 1309 is about 100 million light-years away in the constellation Eridanus. This stunning Hubble ...

The red oval highlights galaxy cluster Abell 370 as seen by Hubble. Abell 370 allowed the telescope to see three different stages of an ancient supernova. A supernova is a spectacular example of a ...

Recently, the Hubble Space Telescope captured a before-and-after image of a star exploding brightly. With the images one year apart, the contrast shows how bright a supernova is, and how that ...
