Hubble Shows Star Cluster’s True Identity

This Hubble picture shows Messier 28, a globular cluster in the constellation of Sagittarius (the Archer), in jewel-bright detail. It is about 18,000 light-years away from Earth.

NASA Invites Media to 57th Annual Robert H. Goddard Memorial Symposium

Media are invited to the 57th Robert H. Goddard Memorial Symposium on March 20-21.

What Scientists Found After Sifting Through Dust in the Solar System

Two recent studies report discoveries of dust rings in the inner solar system: a dust ring at Mercury's orbit, and a group of never-before-detected asteroids co-orbiting with Venus, supplying the dust in Venus' orbit.

Hubble’s Dazzling Display of 2 Colliding Galaxies

Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies first discovered in 1784. A long time ago gravity drew the two galaxies together into the chaotic state we now observe.

What Does the Milky Way Weigh? Hubble and Gaia Investigate

We can't put the whole Milky Way on a scale, but astronomers have been able to come up with one of the most accurate measurements yet of our galaxy's mass.

Hubble’s Advanced Camera for Surveys Resumes Operations

NASA has recovered the Hubble Space Telescope’s Advanced Camera for Surveys instrument, which suspended operations on Thursday, Feb. 28. The final tests were conducted and the instrument was brought back to its operational mode on March 6.

NASA's Webb Telescope Will Study an Iconic Supernova

The closest supernova in centuries exploded in 1987 and 32 years later astronomers continue to study its remains for clues about how stars live and die.

Hubble Peers into the Vast Distance

This picture showcases a gravitational lensing system called SDSS J0928+2031.

Tiny Neptune Moon Spotted by Hubble May Have Broken from Larger Moon

Scientists using NASA's Hubble Space Telescope have come up with an explanation for a mysterious moon around Neptune that they discovered in 2013.

Citizen Scientist Finds Ancient White Dwarf Star Encircled by Puzzling Rings

A volunteer working with the NASA-led Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf ringed by dust and debris.

Hubble Captures Smoking Gun of a Newborn Star

In this image, the NASA/ESA Hubble Space Telescope has captured the smoking gun of a newborn star, the Herbig–Haro objects numbered 7 to 11 (HH 7–11).

NASA’s Webb Is Sound After Completing Critical Milestones

NASA's James Webb Space Telescope has successfully passed another series of critical testing milestones on its march to the launch pad.

Hubble Gets a Celestial Boost

The NASA/ESA Hubble Space Telescope doesn’t usually get much assistance from its celestial subjects ...

Hubble Reveals Dynamic Atmospheres of Uranus, Neptune

Like Earth, Uranus and Neptune have seasons, which likely drive some of the features in their atmospheres. But their seasons are much longer than on Earth, spanning decades rather than months.

Hubble Spies Stellar Time Capsule with Cosmic Distance Markers

This image from the NASA/ESA Hubble Space Telescope reveals an ancient, glimmering ball of stars called NGC 1466.

Hubble Accidentally Discovers a New Galaxy in Cosmic Neighborhood

The universe is very cluttered. Myriad island cities of stars, the galaxies, form a backdrop tapestry.

Hubble Sees Plunging Galaxy Losing Its Gas

The rough-and-tumble environment near the center of the massive Coma galaxy cluster is no match for a wayward spiral galaxy.

NASA's Hubble Helps Astronomers Uncover the Brightest Quasar in the Early Universe

Astronomers have discovered the brightest object ever seen from a time when the universe was less than one billion years old, with the help of NASA's Hubble Space Telescope.

Young Planets Orbiting Red Dwarfs May Lack Ingredients for Life

Rocky planets orbiting red dwarf stars may be bone dry and lifeless, according to a new study using NASA's Hubble Space Telescope.

Nature’s Magnifying Glass Reveals Unexpected Intermediate Mass Exoplanets

Astronomers have found a new exoplanet that could alter the standing theory of planet formation.

Triangulum Galaxy Shows Stunning Face in Detailed Hubble Portrait

NASA's Hubble Space Telescope has produced this stunningly detailed portrait of the Triangulum galaxy (M33).

NASA's TESS Rounds Up its First Planets, Snares Far-flung Supernovae

NASA’s Transiting Exoplanet Survey Satellite (TESS) has found three confirmed exoplanets, or worlds beyond our solar system, in its first three months of observations.

Citizen Scientists Find New World with NASA Telescope

Using data from NASA's Kepler space telescope, citizen scientists have discovered a planet roughly twice the size of Earth located within its star's habitable zone.

Hubble’s Cosmic Holiday Wreath

The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer wreath of reflective dust illuminated by the glittering star.

NASA's Webb Telescope Wrapped in a Mobile Clean Room

The James Webb Space Telescope got a very special wrapping treatment which acts as a “mobile clean room,” safeguarding the technological marvel from contaminants.
