A Gold Mine of Galaxy NuggetsLearn MoreMarch 31, 2015 • News Feature
One telescope finds the treasure chest, and the other narrows in on the gold coins. Data from two European Space Telescope missions, Planck and Herschel, have together identified some of the oldest and rarest clusters of galaxies in the distant cosmos. Planck's all-sky images revealed the clumps of bright galaxies, while Herschel data allowed researchers to inspect the galactic gems more closely and confirm the discovery.
NASA played a key role in the Planck and Herschel missions. NASA's Jet Propulsion Laboratory in Pasadena, California, helped develop science instruments and process data for both missions, which ended, as planned, in 2013.
Planck Mission Explores the History of Our UniverseLearn MoreFebruary 5, 2015 • News Release
Hot gas, dust and magnetic fields mingle in a colorful swirl in this new map of our Milky Way galaxy. The image is part of a new and improved data set from Planck, a European Space Agency mission in which NASA played a key role.
Planck spent more than four years observing relic radiation left over from the birth of our universe, called the cosmic microwave background. The space telescope is helping scientists better understand the history and fabric of our universe, as well as our own Milky Way.
Gravitational Waves from Early Universe Remain ElusiveLearn MoreJanuary 30, 2015 • News Release
A joint analysis of data from the Planck space mission and the ground-based experiment BICEP2 has found no conclusive evidence of gravitational waves from the birth of our universe, despite earlier reports of a possible detection. The collaboration between the teams has resulted in the most precise knowledge yet of what signals from the ancient gravitational waves should look like, aiding future searches.
