Mega Galaxy Merger

Science • nhsc2013-017v1 • Wednesday, May 22nd, 2013

This simulation shows the merging of two massive galaxies, sped up to cover 1.5 billion years of time. The merging galaxies are split into two views: a visible-light view is on the left, in which blue shows young stars and red indicates older stars and dust. The view at right shows emission from dust, which is what infrared telescopes like the Herschel Space Observatory see. When the galaxies finally merge, the strong burst of star formation can be seen best in infrared views.

ESA Euronews: Hot from Cold

Science • nhsc2011-010v1 • Thursday, June 16th, 2011

Over 1.5 million kilometres from Earth, ESA's Herschel space telescope has been observing the Universe for the last two years, studying the infrared radiation emitted by the coldest bodies in the cosmos. See the invisible in this edition of Space.

Herschel: One Year After Launch

Science • nhsc2010-005v1 • Thursday, May 14th, 2009

After only its first year in space, ESA's Herschel infrared space observatory is changing the way scientists view the Universe. From nearby celestial objects to distant ones, from the smallest molecules to the largest galaxies, Herschel is revealing new details about how the Universe behaves.
