Just like archaeologists, who rely on radioactive carbon to date the organic remains from past epochs, astronomers have exploited the radioactive decay of an isotope of aluminum to estimate the age of stars in the nearby Scorpius-Centaurus association, the closest group of young and massive stars to the Sun.

Atlantis launched from Kennedy Space center on April 5, 1991 at 9:22 AM EST and landed at Edwards Air Force Base on April 11 at 6:55 AM EST. The shuttle orbited 93 times at an altitude of 248 nautical miles at an inclination of 28.45 degrees and travelled 2.5 million miles. The mission lasted 5 days, 23 hours, 32 minutes, and 44 seconds. The first spacewalk since 1985 was performed by two astronauts to test the ability to move themselves and equipment about while working on the planned...

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...

Hypernova -- A hypernova is a theoretical type of supernova produced when exceptionally large stars collapse at the end of their lifespan. In a hypernova, the core of the star collapses directly into a black hole and two extremely energetic jets of plasma are emitted from its rotational poles at nearly light speed. These jets emit intense gamma rays, and are a candidate explanation for gamma ray bursts. Theorists have come up with several plausible explanations for hypernovae. It may...

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
