Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA's Great Observatories. This rare galaxy cluster, located 10 billion light-years from Earth, is almost as massive as 500 trillion suns.
In this diagram, the Vega system, which was already known to have a cooler outer belt of comets (orange), is compared to our solar system with its asteroid and Kuiper belts. The ring of warm, rocky debris was detected using NASA's Spitzer Space Telescope,
This artist's concept illustrates an asteroid belt around the bright star Vega. Evidence for this warm ring of debris was found using NASA's Spitzer Space Telescope, and the European Space Agency's Herschel Space Observatory.
NASA's Spitzer Space Telescope and ESA's Herschel mission combined to show this view of the Orion nebula, found below the three belt stars in the famous constellation of Orion the Hunter, highlights fledgling stars hidden in the gas and clouds.
