Artist concept of a galaxy inside of a glowing hydrogen “blob.” Image credit: Nasa/CXC/MWeiss The “coming of age” of galaxies and black holes has been pinpointed, thanks to new data from Nasa’s Chandra X-ray Observatory (Chandra) and other telescopes. This discovery helps resolve the true nature of gigantic blobs of gas observed around very young …

19 October 2009 Article from Popular Mechanics website Nasa’s Interstellar Boundary Explorer (IBEX) spacecraft has made it possible for scientists to construct the first comprehensive sky map of our solar system and its location in the Milky Way galaxy. The new view will change the way researchers view and study the interaction between our galaxy …
1 October 2009 The European Space Agency’s most sophisticated gravity satellite, the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE), has begun mapping Earth’s gravity in unprecedented detail. This image is the first gravity gradient map from GOCE data that ESA has released. Launched on 17 March, GOCE has been through three months of …
