What's the difference between the Swift and GLAST satellites? Both missions look at gamma-ray bursts (GRBs), but in different ways. Swift can rapidly and precisely determine the locations of GRBs and observe their afterglows at X-ray, ultraviolet, an...d optical wavelengths. GLAST will provide exquisite observations of the burst over the gamma ray spectrum, giving scientists their first complete view of the total energy released in these extraordinary events. Beyond GRB science, GLAST is a multipurpose observatory that will study a broad range of cosmic phenomena. Swift is also a multipurpose observatory, but was built primarily to study GRBs.

The Universe is home to numerous exotic and beautiful phenomena, some of which can generate inconceivable amounts of energy. GLAST will open a new window on this high-energy world. With GLAST, astronomers will have a superior tool to study how black ...holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists will be able to search for signals of new fundamental processes that are inaccessible in ground-based accelerators and observatories. GLAST's spectacular high-energy gamma-ray "eyeglasses" will reveal hidden wonders, opening our minds to new possibilities and discoveries, expanding our understanding of the Universe and our place in it.

In this interactive activity adapted from NASA, learn about gamma rays and how astronomers use them to study the universe. Explore the electromagnetic spectrum and investigate how the wavelength, frequency, and energy of a wave are related. Learn how... gamma rays interact with matter and how the Fermi telescope works. Look at false-color gamma ray images of supernova remnants, pulsars, Earth, and gamma ray bursts.

Somewhere out in the vast depths of space, a giant star explodes with the power of millions of suns. As the star blows up, a black hole forms at its center. The black hole blows two blowtorches in opposite directions, in narrow jets of gamma rays. NA...SA's Gamma-ray Large Area Space Telescope, or GLAST, will catch about 200 of these explosions, known as gamma-ray bursts, each year. GLAST's detailed observations may give astronomers the clues they need to unravel the mystery of what exactly produces these gamma-ray bursts, which are the brightest explosions in the universe since the Big Bang.

The Nuclear Test Ban Treaty (1963) of the Cold War lead to the launching of several satellites to detect nuclear energy blasts. Satellites did detect blasts, not from the earth or our moon as expected, but from random places all over the sky. This se...gment from Swift: Eyes through Time covers the accidental discovery of gamma-ray bursts and the 30-plus years quest to understand them. Closed captioning included.

This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes. Building on prior models showing that colliding neutron stars could ...themselves produce a black hole, the video captures cutting-edge research being addressed through modeling, simulation, and visualization.
