Fermi's Large Area Telescope (LAT)
Fermi’s Large Area Telescope (LAT) is the spacecraft’s main scientific instrument. This animation shows a gamma ray (purple) entering the LAT, where it is converted into an electron (red) and a positron (blue). The paths of the particles point back to the gamma-ray source. The LAT maps the whole sky every three hours. (Credit: NASA/Goddard Space Flight Center Conceptual Image Lab)

Hubble- 20 Years of Discovery
Hubble's discoveries have revolutionized nearly all areas of current astronomical research from planetary science to cosmology. Actor and writer Brent Spiner narrates a visual journey back in time and into the farthest reaches of the cosmos.

JWST Mirror Installation
The first six of 18 hexagonal shaped segments that will form NASA’s James Webb Space Telescope’s primary mirror for space observations were readied this week to begin final cryogenic testing at Marshall Space Flight Center in Huntsville, Ala. Testing in Marshall's X-ray and Cryogenic Facility will confirm the mirrors will respond as expected to the extreme temperatures of space.

On the Wings of Webb
The James Webb Space Telescope is designed to unfold after it is deployed and in orbit. The primary mirror with its 18 segments is held in place by a honeycomb-like structure called a backplane. This has three parts -- a center section and two wings. 'Behind the Webb' video series host Mary Estacion travels to ATK in Magna, Utah, where the backplane and, in particular, the wings are built.

Pegasus to Launch NuSTAR from Pacific
The Nuclear Spectroscopic Telescope Array, NuSTAR, will launch on a Pegasus rocket into Earth orbit where it will detect high-energy X-rays to uncover hidden black holes, exploded stars and other features of the universe.

SOFIA’s GREAT Spectrometer Collects First Imagery
The German Receiver for Astronomy at Terahertz Frequencies, or GREAT, is a high-resolution far-infrared spectrometer that finely divides and sorts light into component colors for detailed analysis. Mounted on the 2.5-meter infrared telescope installed in the SOFIA flying observatory operated by NASA and German Aerospace Center, GREAT collected its first science spectra on April 6, 2011.

SOFIA Observatory Finishes Open-Door Flight Tests
NASA's SOFIA flying observatory recently completed the second series of envelope-expansion flight tests with its telescope door open. The SOFIA is now fully cleared for astronomy missions at altitudes up to 45,000 feet and telescope elevations up to 58 degrees. After installation and checkout of remaining systems, the airborne observatory will begin infrared astronomy missions late this year.

Spitzer's Warm Mission
After more than five years, Spitzer is completing its original assignment to study the cool universe and is now moving on to a new 'warm' career.

Stretching Webb's Wings
'Behind the Webb' shows how the James Webb Space Telescope's protective sunshield will be folded up inside the rocket that carries it into orbit. Engineers explain to 'Behind the Webb' how the sunshield will be unfurled from a million miles away.

Swift's 500th Gamma Ray Burst
On April 13, 2010, NASA's Swift Gamma-ray Burst Explorer satellite discovered its 500th burst. Swift's main job is to quickly localize each gamma-ray burst (GRB), report its position so that others can immediately conduct follow-up observations, and then study the burst using its X-ray and Ultraviolet/Optical telescopes. Some notable bursts are identified in the video.

Testing the Webb Mirror Segments
Engineers at the Goddard Space Flight Center test the robotic-like fixture that will place the primary mirror segments of the Webb Telescope onto the telescopes back plane.

The Camera That Saved Hubble
Two of the unsung heros of NASA's Hubble mission are a camera and the team from JPL that put it all together.

The Day NASA's Fermi Dodged a 1.5-ton Bullet
On March 29, 2012, the science team for NASA's Fermi Gamma-ray Space Telescope learned that a defunct Cold-War spy satellite would pass too close for comfort on April 4. The two spacecraft were expected to occupy the same point in space within 30 milliseconds of each other, which meant that Fermi had to get out of the way.

The Hubble Legacy- Exoplanets
Three astronomers in NASA Goddard's Exoplanets and Stellar Astrophysics Laboratory discuss how Hubble's coronagraph and resulting images have helped scientists find planets orbiting distant stars.

The Hubble Legacy- Galaxy Evolution
Three astronomers explain how Hubble acts like a time machine by detecting which galaxies are moving toward and away from us.

Webb FAQ
Astrophysicist Dr. Amber Straughn takes you on a quick journey of facts and images to explain what the James Webb Space Telescope will tell us about the cosmos

Webb Mirrors Arrive at NASA Goddard
James Webb Space Telescope's secondary mirror, along with a primary mirror segment arrived at NASA's Goddard Space Flight Center in Greenbelt, Md., on Nov. 5, 2012.

Webb Telescope- Evolution of the Universe
Galaxies congregate in clusters and superclusters, and at larger scales superclusters seem to blend into chains and filaments that span vast distances. This so-called cosmic web seems to be the foundation on which the universe is built. Webb will explore how stars, young galaxies and dark matter worked to create large-scale cosmic structure.
