NASA’s Hubble Space Telescope captured this image of Comet ISON on Oct. 9, 2013. The image suggests that the comet is intact, a good sign that it will survive perihelion next month when it dives to within one million miles of the Sun’s surface.

After 32 months of agony and introspection, the Kennedy Space Center was again rocked by the roar of shuttle main engines and Solid Rocket Boosters on the morning of 29 September 1988. It was the dawn of a new era. Photo Credit: NASA

Twenty-five years have now passed since STS-26, the mission which laid the ghosts of Challenger to rest and opened the gates for a second Golden Age of shuttle operations. Photo Credit: NASA
Twenty-five years have now passed since the voice of launch commentator Hugh Harris exulted “Americans return to space” on the morning of [...]

This Tuesday, Oct. 1, NASA will again attempt to do something that has never been done before: photograph a comet from another world. Various spacecraft on the surface and in orbit around [...]
The Hubble Space Telescope has imaged what appears to be more than 160,000 star clusters in a group of galaxies known as Abell 1689. Image Credit: NASA, ESA, J.

In an effort to understand how black holes shape the evolution of galaxies, astronomers spent eight months creating a series of time-lapse movies from 400 observations made by NASA’s Hubble Space Telescope. The movies, taken from observations conducted over a 13-year period from 1995-2008, show a 5,000-mile-long jet [...]

Astronomers using NASA’s Hubble Space Telescope have solved a 40-year mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy.

NASA’s Hubble Space Telescope recently provided the strongest evidence yet that short-duration gamma ray bursts are produced by the merger of two small, super-dense stellar objects.

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.
