Bullying Black Holes Force Galaxies to Stay Red and DeadLearn MoreFebruary 25, 2014 • News Release
Herschel has discovered massive elliptical galaxies in the nearby Universe containing plenty of cold gas, even though the galaxies fail to produce new stars. Comparison with other data suggests that, while hot gas cools down in these galaxies, stars do not form because jets from the central supermassive black hole heat or stir up the gas and prevent it from turning into stars.
Herschel Telescope Detects Water on Dwarf PlanetLearn MoreJanuary 14, 2014 • News Release
Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, Ceres. Plumes of water vapor are thought to shoot up periodically from Ceres when portions of its icy surface warm slightly.
NASA and ESA Telescopes Help Solve Mystery of Ultra-Compact, Burned-Out GalaxiesLearn MoreJanuary 22, 2014 • News Release
Astronomers using NASA's Hubble and Spitzer Space Telescopes, Europe's Herschel Space Observatory, and many ground-based telescopes have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe.
The Rise and Fall of Galactic CitiesLearn MoreDecember 18, 2013 • Feature
In the fable of the town and country mice, the country mouse visits his city-dwelling cousin to discover a world of opulence. In the early cosmos, billions of years ago, galaxies resided in the equivalent of urban or country environments. Those that dwelled in crowded areas called clusters also experienced a kind of opulence, with lots of cold gas, or fuel, for making stars.
