After years of searching astronomers have found a secret companion hidden in the aftermath of a star that exploded. This is an artist’s impression of supernova 1993J, which exploded in the galaxy M81. Using the Hubble Space Telescope, astronomers have identified the blue helium-burning companion star, seen at the center of the expanding nebula of debris from the supernova.
We are used to Hubble capturing astonishing images of supernovae and planetary nebulae created by huge explosions of dying stars. In this image this star went out with a whimper, at least that's how NASA put it. None the less it still is an amazing and gorgeous image.
Far away, deep in space, a new baby star has been born in the universe. Hubble and ESA teamed up to bring us this remarkable image. This young star is zooming through the cosmos at supersonic speed with a tail made up from the very star that made it. The the gas and dust that surrounds it will eventually become planets and moons of this newborn alien sun.
It's hard to believe the captivating and gorgeous nebula in this image was created by one tiny sun-like star that exploded. Planetary nebulas are kind of like snowflakes, they are extremely intricate and beautiful and no two are exactly alike. Scattered throughout the universe these dazzling cosmic marvels give scientist a glimpse into our own star's distant future.
Resting about 200,000 light-years away from our own Milky Way galaxy are two smaller galaxies teaming with millions of stars. They are the Large and Small Magellanic Clouds and can only be seen in the Southern Hemisphere as the trail beside the Milky Way. Now astronomers have the best most detailed ultraviolet light surveys ever thanks to NASA's Swift satellite.
How many rings do you see in this striking new image of the galaxy Messier 94 (NGC 4736) as seen by the infrared eyes of NASA's Spitzer Space Telescope? While at first glance one might see a number of them, astronomers believe there is just one.
