Whitney Clavin, NASA Jet Propulsion Laboratory A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos. In one of the longest surveys the telescope will have ever performed, astronomers have begun a three-month expedition trawling for faint galaxies billions of light-years away. The results are already yielding surprises. "If you think of our survey as fishing for galaxies in the cosmic sea, then we are finding...

firestorm of star birth
2014-08-28 10:04:02

NASA/Space Telescope Science Institute/ESA Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate. The discovery was made possible through combined observations from NASA’s Hubble and Spitzer space telescopes, the W.M. Keck Observatory in Mauna Kea, Hawaii, and the European Space...

Hubble Reveals First Visual Evidence Of Milky Way's Formative Years
2013-11-14 16:35:20

HubbleSite NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years. "For the first time we have direct images of what the Milky Way looked like in the past," said study co-leader Pieter G. van Dokkum...

New Hubble Data Reveals Ancient Dusty Galaxies
2012-10-10 09:08:37

April Flowers for redOrbit.com - Your Universe Online Dust can be the bane of any good housekeeper or computer technician. However, it is an important building block for stars and planets, and astronomers need to understand how cosmic dust forms over time. This understanding is an integral step in figuring out the evolution of galaxies and the stars and planets that they´re made of. Assistant professor Steven Finkelstein, of the University of Texas at Austin, and his colleagues are...

Spitzer And Hubble Telescopes Discover Furthest Galaxy Ever
2012-09-19 19:01:35

Lee Rannals for redOrbit.com — Your Universe Online A long time ago, in a galaxy far, far away, light took off, then traveled 13.2 billion light-years until it was finally picked up by NASA's telescopes. Astronomers have identified the furthest galaxy ever using NASA's Spitzer and Hubble space telescopes. The light captured by the telescope was from when the universe was just 500 million years old, according to NASA. "This galaxy is the most distant object we have ever...

The following is a statement from NASA's Chief Scientist, Waleed Abdalati, on the Space Telescope Science Institute naming its astronomical database the Barbara A. Mikulski Archive for Space Telescopes (MAST). MAST holds science data from the Hubble Space Telescope and 14 other NASA missions. "The Space Telescope Science Institute's decision to name its database for Senator Mikulski is an honor very much deserved. She is a tremendous advocate and supporter for science, NASA and the...

Image 1 - VISTA Stares Deep into the Cosmos
2012-03-22 07:52:34

[ Watch the Video ] Treasure trove of new infrared data made available to astronomers ESO's VISTA telescope has created the widest deep view of the sky ever made using infrared light. This new picture of an unremarkable patch of sky comes from the UltraVISTA survey and reveals more than 200 000 galaxies. It forms just one part of a huge collection of fully processed images from all the VISTA surveys that is now being made available by ESO to astronomers worldwide. UltraVISTA is a...

Young Dwarf Galaxies Found Bursting With Stars
2011-11-10 10:17:24

[ Video 1 ] | [ Video 2 ] Using its near-infrared vision to peer 9 billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation. While dwarf galaxies are the most common type of galaxy in the universe, the rapid star-birth observed in these newly found examples may force astronomers to reassess their understanding of the ways in which galaxies form. The galaxies are a hundred times less massive,...

Image 1 - New Black Hole Anatomy Revealed
2011-09-29 07:15:57

A fleet of spacecraft including ESA's XMM-Newton and Integral have shown unprecedented details close to a supermassive black hole. They reveal huge 'bullets' of gas being driven away from the 'gravitational monster'. The black hole that the team chose to study lies at the heart of the galaxy Markarian 509, 500 million light years away in space. This black hole is colossal, containing 300 million times the mass of the Sun and growing more massive every day as it continues to feed....
