Astrophysicists make stellar discovery about galaxies far, far away

A new study observes 13 smaller satellite galaxies orbiting around the immense Andromeda galaxy in a way similar to how the planets in our solar system orbit around the sun. The galaxies are orbiting on a thin, pancake-like plane at a scale 900 million times larger than our own solar system.

An image gallery gift from NASA's Swift satellite

Of the three telescopes carried by NASA's Swift satellite, only one captures cosmic light at energies similar to those seen by the human eye. Although small by the standards of ground-based observatories, Swift's Ultraviolet/Optical Telescope (UVOT) plays a critical role in rapidly pinpointing the locations of gamma-ray bursts (GRBs), the brightest explosions in the cosmos.

New free e-books available about two famous NASA space telescopes

NASA's Hubble Space Telescope has been providing astounding images of the universe since April 1990 and has led to remarkable discoveries. NASA's James Webb Space Telescope is the next-generation telescope that will peer even deeper into space and unveil even more mysteries. Both of these extraordinary telescopes are now the topics of two free e-books available from the Apple iBookstore.
