Latest Space Telescope Science Institute Stories
In honor of its upcoming 25th anniversary, NASA’s Hubble Space Telescope has revisited the site where it captured one of its most iconic images, the three giant columns of cold gas known as the “Pillars of Creation.”
A titanic eruption took that took place at least two million years ago forced gases and other materials outward at speeds of up to two million miles per hour, and astronomers are just now witnessing the aftermath of the explosion thanks to NASA’s Hubble Space Telescope.
Astronomers using NASA’s Hubble Space Telescope have completed the largest and most sensitive visible-light imaging survey of dusty debris disks around other stars.
Every year, NASA’s Chandra X-ray Observatory looks at hundreds of objects throughout space to help expand our understanding of the Universe. Ultimately, these data are stored in the Chandra Data Archive, an electronic repository that provides access to these unique X-ray findings for anyone who would like to explore them.
Out of every four proposals submitted to gain observation time on the Hubble Space Telescope, three are denied. You might think that these denials are based strictly on the merits of the study being proposed and the current viewing patterns of the telescope, but you would be wrong.
WASHINGTON, Sept. 9, 2014 /PRNewswire-USNewswire/ -- Using NASA's Hubble Space Telescope, astronomers have discovered a companion star to a rare type of supernova.
Using NASA’s Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a “zombie star” after an unusually weak supernova explosion.
NASA's James Webb Space Telescope and Chandra X-ray observatory have something in common: a huge test chamber used to simulate the hazards of space and the distant glow of starlight.
Space Telescope Science Institute -- STScI mission statement: We bring the cosmos to Earth We carry out this vision by empowering the astronomy community to produce new scientific discoveries and by bringing the benefits of this research to the public. We make the best astronomical facilities productive for the largest number of scientists, and we promote new missions with the greatest potential for unlocking the secrets of the universe. We have done this with HST, and we will do the...
Hubble Space Telescope -- The first large orbital optical observatory. Built from 1978 to 1990 at a cost of $1.5 billion, the HST (named for astronomer E. P. Hubble) was expected to provide the clearest view yet obtained of the universe. Using a Ritchey-Chrtien design that affords wider and flatter fields of view than traditional Cassegrain systems, the telescope has a 7.9-ft (2.4-m) primary mirror that can observe 24 hours a day (but usually observes less than 20% of the time) in a sky...
