Last week, the European Space Agency (ESA) announced that it will delay the launch of its ambitious Gaia mission to observe and catalog around 1 billion astronomical objects—or approximately 1 percent […]

Herschel Links Water Around Jupiter to Comet Impact

This map shows the distribution of water in the stratosphere of Jupiter as measured with the Herschel Space Observatory. White and cyan indicate highest concentration of water, and blue indicates lesser amounts. The map has been superimposed over an image of Jupiter taken at visible wavelengths with the NASA/ESA Hubble Space Telescope. Image credit: […]

Herschel Discovers Some of the Youngest Stars Ever Seen

Astronomers have found some of the youngest stars ever seen thanks to the Herschel space observatory, a European Space Agency mission with important NASA contributions. Dense envelopes of gas and dust surround the fledging stars known as protostars, making their detection difficult until now. The discovery gives scientists a window into the earliest and […]
