Powerful Explosion Since Big Bang Seen

Powerful Explosion Since Big Bang Seen ~ Bathed in bright blue and fluorescent pink light, the galaxy cluster in this image is home to the most powerful explosion since the big bang. What’s more, the explosion is ongoing and has been continuing for the last 100 million years, releasing as much energy as hundreds of millions of gamma ray bursts. The blast is generated by the largest black hole in the known universe, a gravitational monster over 10 billion times the mass of our sun.

Hubble Space Telescope composite image
This is a Hubble Space Telescope composite image of a supernova explosion designated SN 2014J in the galaxy M82. At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. NASA, ESA, A.Goobar (Stockholm University), and the Hubble Heritage Team (STScI/AURA).

Hubble’s scientific bounty has benefited a wide range of astronomical and astrophysical fields, including the study of planets, moons and small icy bodies in the outer solar system and the cosmological history of the universe. Here’s a look at a few of Hubble’s greatest hits.

Astronomers calculate this behemoth has consumed almost 600 million times the mass of the sun in order to generate such a powerful explosion. To create the image, X-ray and radio wave data was combined with optical images from the Hubble Space Telescope. The X-rays are shown in blue and were detected by NASA’s Chandra X-Ray Observatory. They indicate the hot gas that makes up most of the mass of this enormous galaxy cluster.
 
Herschel's Coolest Infrared
Herschel's Coolest Infrared Hotshots.

On April 29, the European Space Agency announced that its premier infrared space observatory had run out of coolant and the mission had come to an end. Observing the cosmos in far-infrared wavelengths, the space telescope has given us some of the most striking views of cool nebulae, star forming regions, comets being pulverized around nearby stars, even asteroids buzzing around our own solar system. As we say goodbye to the historic mission, and astronomers continue to analyze the huge wealth of data Herschel has left us with, it's time to have a look back at some of the mission's most spectacular observations. In this picture, embryonic stars feed on the gas and dust clouds deep inside the Orion Nebula. This image combines far-infrared data by Herschel and mid-infrared data by NASA's Spitzer space telescope.

Shown in pink are vast cavities each over 600,000 light-years in diameter, blasted out by powerful supersonic jets from the gargantuan galaxy at the very heart of this image. These cavities have displaced a trillion suns’ worth of mass and have been filled with magnetized, extremely high-energy electrons emitting radio waves, which were detected by the Very Large Array radio telescope. Most, if not all, galaxies are thought to contain supermassive black holes at their centers. Astronomers are still trying to determine which forms first — the black hole, or the galaxy around it. Galaxy cluster MS 0735.6+7421 is located 2.6 billion light-years away in the constellation Camelopardalis, the Giraffe.
