Hubble Captures Cluster of Galaxies and Homeless Stars

This sparkling picture features a massive galaxy cluster named RXC J0232.2-4420.

NASA’s Fermi Satellite Celebrates 10 Years of Discoveries

The Fermi Gamma-ray Space Telescope celebrates 10 years of using the highest-energy form of light in the universe to observe phenomenon from black holes to cosmic rays and thunderstorms.

Hubble Images a Galaxy with Threads of Blue

A ripple of bright blue gas threads through this galaxy like a misshapen lake system.

Engineers Solve Excessive Heat Removal from NASA’s Webb Telescope

To keep heat away from the sensitive instruments, a majority of the electronics used to power and operate the instruments are housed in a compartment below ISIM, where specially designed baffles direct the heat safely into space and away from any cold surfaces of the observatory.

Hubble Spots a Green Cosmic Arc

This Hubble Space Telescope image shows a cluster of hundreds of galaxies located about 7.5 billion light-years from Earth.

Fermi Status Update

Both instruments aboard NASA’s Fermi Gamma-ray Space Telescope have resumed science observations.

Hubble’s Galaxy Cluster Cornucopia

The swirling spiral to the lower left of the frame is far from the most interesting spectacle here — behind it sits a galaxy cluster.

NASA Awards Contract for Space Telescope Mission

NASA has awarded a contract to Ball Aerospace and Technologies Corporation, Boulder, Colorado, for the primary instrument components for the Wide Field Infrared Survey Telescope (WFIRST).

Hubble Catches a Spiral Galaxy in Disguise

NGC 1032 cleaves the quiet darkness of space in two in this image from the NASA/ESA Hubble Space Telescope.

NASA’s New Planet Hunter Snaps Initial Test Image, Swings by Moon Toward Final Orbit

After launching April 18, TESS has completed its lunar flyby to put it on track for its final science orbit, and has released a first test image.

Astronomers Release Most Complete Ultraviolet-Light Survey of Nearby Galaxies

An international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.

Hubble Spies Glowing Galaxies in Massive Cluster

In the darkness of the distant universe, these galaxies resemble glowing fireflies, flickering candles, charred embers floating up from a bonfire, and light bulbs softly shining.

NASA’s NICER Mission Finds an X-ray Pulsar in a Record-fast Orbit

Scientists analyzing the first data from NICER have found two stars that revolve around each other every 38 minutes, the shortest-known orbital period for a certain class of pulsar binary system.

NASA’s Webb Observatory Spacecraft Element Environmental Testing Update

The spacecraft element of NASA’s James Webb Space Telescope recently completed its first two major launch environmental tests at Northrop Grumman Aerospace Systems in Redondo Beach, California, and will soon undergo further tests to ensure it will handle the rigors of launch and the harsh environment of space.

Hubble Finds a Monster in the Deep

Though the bright, light-speckled foreground galaxy in the lower left is eye-catching, it is far from the most intriguing object in this NASA/ESA Hubble Space Telescope image.

X-ray Navigation Considered for Possible CubeSat Mission; NASA Studies as a Technique for Human Exploration

A team led by the Smithsonian Astrophysical Observatory plans to include the technology on a proposed CubeSat mission to the Moon, and NASA engineers are now studying the possibly of adding the capability to future human-exploration spacecraft.

NASA's Rossi X-ray Timing Explorer Leaves Scientific ‘Treasure Trove’

NASA's Rossi X-ray Timing Explorer (RXTE) satellite has fallen back to Earth. From 1996 to 2012, RXTE provided scientists with an unprecedented look into the extreme environments around neutron stars and black holes.

Hubble Sights Galaxy Stuck in the Middle

This pretty, cloud-like object may not look much like a galaxy but it is in fact something known as a lenticular galaxy.

Stellar Thief Is the Surviving Companion to a Supernova

This picture is the most compelling evidence that some supernovas originate in double-star systems.

NASA’s James Webb Space Telescope Could Potentially Detect the First Stars and Black Holes

The first stars in the universe blazed to life about 200 to 400 million years after the big bang.

NASA’s Rossi X-ray Timing Explorer Spacecraft to Re-enter Over Tropics

Fragments of the Rossi X-ray Timing Explorer (RXTE) spacecraft, a NASA mission to observe the time variation of astronomical X-ray sources, are expected to fall to Earth on or about May 1. The mission was terminated and the spacecraft decommissioned on Jan. 12, 2012.

2020 Decadal Survey Missions: At a Glance

Any telescope that reaches the launch pad in the 2030s likely will look much different than the concepts four teams are currently studying to inform the 2020 Decadal Survey for Astrophysics, but the studies do offer a roadmap.

NASA Teams Study the Agency’s Future in Astrophysics; Tackle Formidable Technology Challenges

As in past decades, the agency won’t make that decision in a vacuum or without understanding the technical obstacles, which are formidable.

NASA Planet Hunter on Its Way to Orbit

NASA’s Transiting Exoplanet Survey Satellite (TESS) has launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life.
