Peering ever further back in space and time, the Hubble Space Telescope has glimpsed the largest known group of the faintest and youngest primordial galaxies ever—over 250—some of which are estimated […]

The Coming of the Cosmic Old Age: New Survey Finds the Universe's Energy Output Is Decreasing With Time

A composite image of a galaxy as seen in different wavelengths by the GAMA survey. The results of the survey, which studied more than 200,000 galaxies in the local Universe, revealed that the latter’s total energy output has decreased by at least 50 percent during the last 2 billion years.

Astronomers today announced an exciting discovery: the first direct evidence for what happened during the first few seconds or so of the birth of our […]

'End of Days' for Europe's Ambitious GOCE and Planck Missions to Explore Earth and the Cosmos

 

The European Space Operations Centre (ESOC) in Darmstadt, Germany, will bid a fond farewell to the GOCE and Planck missions this week. Both missions have contributed enormously to our understanding of Earth and the Universe. Photo Credit: ESOC

Two ambitious science missions—one circling Earth closer than any other research satellite, the other orbiting […]
