The Hubble telescope is back in business after its latest service mission. Here are some images taken with the new WFC3, which can look even deeper into space and time with exposure times of many hours.
Peering much farther away, astronomers have ambitious plans to use Hubble to make the deepest-ever portrait of the universe in near-infrared light. The resulting picture may reveal never-before-seen infant galaxies that existed when the universe was less than 500 million years old. Hubble also is now significantly more well-equipped to probe and further characterize the behavior of dark energy, a mysterious and little-understood repulsive force that is pushing the universe apart at an ever-faster rate.
The ending animation shows the explosion of a super massive star. Stars greater than eight times the mass of our Sun will self-detonate as supernovae. Supernovae can briefly outshine an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova radiates as much energy as the Sun could emit over its life span. The star is shredded and blown into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant. Hubble Space Telescope spectroscopic observations yield the chemistry cooked up by the supernova, including oxygen, nitrogen, and carbon — the materials of life as we know it.
