Hubble Spotlight on Irregular Galaxy IC 3583

Irregular galaxy IC 3583 sits some 30 million light-years away in the constellation of Virgo.

Tangled Threads Weave Through Cosmic Oddity

New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before.

NASA's Webb Telescope Clean Room 'Transporter'

What looks like a teleporter from science fiction being draped over NASA's James Webb Space Telescope, is actually a "clean tent." The clean tent protects Webb from dust and dirt when engineers at NASA's Goddard Space Flight Center transport the telescope out of the relatively dust-free cleanroom and into the vibration and acoustics testing areas.

Hubble Spies Spiral Galaxy

Spiral galaxy NGC 3274 is a relatively faint galaxy located over 20 million light-years away in the constellation of Leo (The Lion).

NASA's John C. Mather Named Honorary Member of the Optical Society

Dr. John Mather, NASA's Nobel Prize-winning scientist, has received another honor to add to his many accolades -- he has been named an honorary member of the Optical Society.

Hubble Nets a Subtle Swarm

This Hubble image shows NGC 4789A, a dwarf irregular galaxy in the constellation of Coma Berenices.

Hubble Steals a Look at a Hungry Giant

Astronomers think that this lenticular galaxy, NGC 1222, is in the process of swallowing up two much smaller dwarf galaxies that strayed too close to it.

Hubble Takes Flight with the Toucan and the Cluster

NGC 299 is an open star cluster located within the Small Magellanic Cloud just under 200,000 light-years away.

James Webb Space Telescope Mirrors Will Piece Together Cosmic Puzzles

The primary mirror of NASA's James Webb Space Telescope that consists of 18 hexagonal mirrors looks like a giant puzzle piece standing in the massive clean room of NASA's Goddard Space Flight Center in Greenbelt, Maryland. The telescope will help piece together puzzles scientists have been trying to solve throughout the cosmos.

NASA Completes Webb Telescope Center of Curvature Pre-test

Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb’s fully assembled primary mirror, called a Center of Curvature test.

Final Sunshield Layer Completed for NASA’s James Webb Space Telescope

The last of the five sunshield layers responsible for protecting the optics and instruments of NASA’s James Webb Space Telescope is now complete.

Hubble Admires a Youthful Globular Star Cluster

The globular cluster shown in this Hubble, NGC 362, is one of the more unusual ones.

A Dead Star's Ghostly Glow

The eerie glow of a dead star, which exploded long ago as a supernova, reveals itself in this NASA Hubble Space Telescope image of the Crab Nebula.

NASA Missions Harvest a Passel of ‘Pumpkin’ Stars

NASA's Kepler and Swift missions have found rapidly rotating stars producing more than 100 times our own sun's peak X-ray emission. Spinning so fast they resemble pumpkins, the stars likely formed by mergers of sun-like stars.

Hubble Spins a Web Into a Giant Red Spider Nebula

Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula, located some 3,000 light-years away in the constellation of Sagittarius.

NASA, Citizen Scientists Discover Potential New Hunting Ground for Exoplanets

Via a NASA-led citizen science project, eight people with no formal training in astrophysics helped discover what could be a fruitful new place to search for planets outside our solar system – a large disk of gas and dust encircling a star known as a circumstellar disk.

Hubble Sees Cassiopeia’s Unusual Resident

Hubble found a spiral galaxy with unusual star formation going on, some 38 million light-years away in Cassiopeia.

Hubble Reveals Observable Universe Contains 10 Times More Galaxies Than Previously Thought

The universe suddenly looks a lot more crowded than previously though thanks to a deep sky census by Hubble and major observatories.

Hubble Peers Into the Center of a Spiral

This Hubble image shows the central region of a spiral galaxy known as NGC 247.

Hubble Detects Giant 'Cannonballs' Shooting from Star

Hubble detected superhot blobs of gas ejected from a dying star so fast it would take only 30 minutes for them to travel from Earth to the moon.

NASA’s TESS Mission Will Provide Exciting Exoplanet Targets for Years to Come

NASA's search for planets outside of our solar system has mostly involved very distant, faint stars. The upcoming Transiting Exoplanet Survey Satellite, by contrast, will look at the brightest stars in our solar neighborhood.

X-ray Telescopes Find Evidence for Wandering Black Hole

Astronomers have used NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton X-ray observatory to discover an extremely luminous, variable X-ray source located outside the center of its parent galaxy.

Hubble Explores the Hidden Dark Side of NGC 24

This shining disk of a spiral galaxy sits approximately 25 million light-years away from Earth in the constellation of Sculptor.

NASA's Fermi Finds Record-breaking Binary in Galaxy Next Door

Scientists have found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system is in a small nearby galaxy and contains a massive star and a crushed stellar core that interact to produce a flood of gamma rays, the highest-energy form of light.

NASA’s Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa

Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.
