Fireworks in the Early Universe
External • September 14, 2012
Galaxies in the early universe grew fast by rapidly making new stars. Such prodigious star formation episodes, characterized by the intense radiation of the newborn stars, were often accompanied by fireworks in the form of energy bursts caused by the massive central black hole accretion in these galaxies. This discovery by a group of astronomers led by Peter Barthel of the Kapteyn Institute of the University of Groningen in the Netherlands is published today in the Astrophysical Journal Letters.
Herschel Sees Intergalactic Bridge Aglow with Stars
News Release • May 17, 2012

Overfed Black Holes Shut Down Galactic Star-Making
News Release • May 9, 2012
The Herschel Space Observatory has shown galaxies with the most powerful, active black holes at their cores produce fewer stars than galaxies with less active black holes. The results are the first to demonstrate black holes suppressed galactic star formation when the universe was less than half its current age.

Herschel Finds Oceans of Water in Disk of Nearby Star
News Release • October 20, 2011
Using data from the Herschel Space Observatory, astronomers have detected for the first time cold water vapor enveloping a dusty disk around a young star. The findings suggest that this disk, which is poised to develop into a solar system, contains great quantities of water, suggesting that water-covered planets like Earth may be common in the universe.
Space Observatory Provides Clues to Creation of Earth's Oceans
News Release • October 5, 2011
Astronomers have found a new cosmic source for the same kind of water that appeared on Earth billions of years ago and created the oceans. The findings may help explain how Earth's surface ended up covered in water.
Herschel Telescope Detects Oxygen Molecules in Space
News Release • August 1, 2011
The Herschel Space Observatory's large telescope and state-of-the-art infrared detectors have provided the first confirmed finding of oxygen molecules in space. The molecules were discovered in the Orion star-forming complex.
Herschel Helps Solve Mystery Of Cosmic Dust Origins
News Release • July 7, 2011
New observations from the infrared Herschel Space Observatory reveal that an exploding star expelled the equivalent of between 160,000 and 230,000 Earth masses of fresh dust. This enormous quantity suggests that exploding stars, called supernovae, are the answer to the long-standing puzzle of what supplied our early universe with dust.
Young Star Shooting Water Bullets
External • June 21, 2011
Observations with Herschel-HIFI of water in a young Sun-like star reveal high-velocity bullets moving at more than 200,000 kmh from the star. This can be compared to the velocity of a bullet from an AK47 rifle, which is 2500 kmh or 80 times slower.
Herschel Space Observatory Discovers the Clearing Out of Star-Forming Gas in Mergers of Gas-Rich Galaxies
External • May 9, 2011
Herschel Space Observatory has detected massive amounts of molecular gas gusting at high velocities - in some cases in excess of 1000 kilometers per second - from the centers of a sample of merging galaxies.
Caught in the Act: Cascading Material Pours onto a Young Star

Herschel Finds Water in a Cosmic Desert
Feature • September 1, 2010
The Herschel infrared space observatory has discovered that ultraviolet starlight is the key ingredient for making water in space. It is the only explanation for why a dying star is surrounded by a gigantic cloud of hot water vapor. Herschel is a European Space Agency mission with important participation from NASA.
