Search for New Worlds at Home With NASA’s Planet Patrol Project

Help NASA find exoplanets, worlds beyond our solar system, through a newly launched website called Planet Patrol.

Hubble Views a Galaxy on the ‘Dark Side’

The stellar disk of this galaxy, NGC 5585, extends over 35,000 light-years across. When compared with galaxies of a similar shape and size, NGC 5585 stands out by having a notably different composition: it contains a far higher proportion of dark matter.

NASA's Webb Will Explore the Cores of Merging Galaxies

Researchers will study four nearby merging galaxies in unprecedented detail.

Hubble Locks Eyes With a Snake

This stunning barred spiral galaxy, NGC 2835, has a width of just over half that of the Milky Way. The twisting patterns created by the multiple spiral arms of NGC 2835 create the illusion of an eye. This is a fitting description, as this magnificent galaxy resides near the head of the southern constellation of Hydra, the water snake.

Hubble Captures Crisp New Portrait of Jupiter's Storms

Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the famous Great Red Spot region gearing up to change color – again.

NASA Missions Spy First Possible ‘Survivor’ Planet Hugging White Dwarf Star

An international team of astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope has reported what may be the first intact planet found closely orbiting a white dwarf, the dense leftover of a Sun-like star, only 40% larger than Earth.

NASA’s Partnership Between Art and Science: A Collaboration to Cherish

NASA has long used art to represent everything from abstract astrophysical concepts to presentations of satellites in orbit.

Hubble Stows a Pocketful of Stars

Globular cluster NGC 1805, a tight grouping of thousands of stars is, located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. In the dense center of one of these clusters, stars are 100 to 1,000 times closer together than the nearest stars are to our Sun.

Hubble Observations Suggest a Missing Ingredient in Dark Matter Theories

In measuring how dark matter's gravity distorts space, researchers found that small-scale concentrations of dark matter in clusters produce distortions 10 times stronger than expected. This evidence is based on observations of several massive galaxy clusters by Hubble and the European Southern Observatory's Very Large Telescope (VLT) in Chile.

Hubble Targets Tilted Galaxy

The blue and orange stars of the faint galaxy named NGC 2188 sparkle in this Hubble image. NGC 2188 is estimated to be about 50,000 light-years across, which would make it roughly half the size of our Milky Way galaxy.

Primary Mirror for NASA’s Roman Space Telescope Completed

The Nancy Grace Roman Space Telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, has been completed.

Hubble Views Edge of Stellar Blast

This Hubble Space Telescope image depicts a small section of the Cygnus supernova blast wave, the result of the "death" of a star 20 times more massive than our Sun 10,000 to 20,000 years ago. Light from this supernova takes around 2,400 years to reach Earth.

NASA’s Webb “Powerhouse” Solar Array Reconnects to the Telescope

One kilowatt is about what it takes to heat up some leftovers in a microwave — or to power the largest and most technically advanced telescope ever built. Thanks to its solar array, NASA’s James Webb Space Telescope will stay energy-efficient more than 1 million miles (1.5 million kilometers) from Earth.

Hubble Maps Giant Halo Around Andromeda Galaxy

In a landmark study, scientists using NASA's Hubble Space Telescope have mapped the immense halo of gas enveloping the Andromeda galaxy, our nearest large galactic neighbor.

NASA Missions Explore a ‘TIE Fighter’ Active Galaxy

Not so long ago, astronomers mapped a galaxy far, far away using radio waves and found it has a strikingly familiar shape. In the process, they discovered the object, called TXS 0128+554, experienced two powerful bouts of activity in the last century.

Ground Segment Testing a Success for NASA’s James Webb Space Telescope

Testing teams have successfully completed a critical milestone focused on demonstrating that NASA’s James Webb Space Telescope will respond to commands once in space.

Hubble Hooks a Supernova Host Galaxy

Galaxy NGC 2442, seen here by the Hubble Space Telescope, is nicknamed the Meathook galaxy owing to its extremely asymmetrical and irregular shape.

Hubble Snaps Close-Up of Celebrity Comet NEOWISE

The Hubble Space Telescope has snapped the closest images yet of the sky's latest visitor to make headlines, comet NEOWISE, after it passed by the Sun. This is the first time Hubble has photographed a comet of this brightness at such resolution after this close of a pass by the Sun.

Unveiling Rogue Planets With NASA’s Roman Space Telescope

New simulations show that NASA’s Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets – freely floating bodies that drift through our galaxy untethered to a star.

NASA's Webb to Study Quasars and Their Host Galaxies in Three Dimensions

Shortly after the launch of NASA’s James Webb Space Telescope, scientists plan to study the effect of three carefully selected quasars on their host galaxies in a program called Q3D.

Citizen Scientists Discover Dozens of New Cosmic Neighbors in NASA Data

We’ve never met some of the Sun’s closest neighbors until now. In a new study, astronomers report the discovery of 95 objects known as brown dwarfs, many within a few dozen light-years of the Sun.

Hubble Catches a Ring of Stellar Wildfire

NGC 1614 is an eccentrically shaped galaxy ablaze with activity. NGC 1614 is the result of an active galactic merger, which creates its peculiar appearance, including a tidal tail. The cosmic collision also drives a burst of star formation that started in the core and has slowly spread outward through the galaxy.

Hubble Finds That Betelgeuse's Mysterious Dimming Is Due to a Traumatic Outburst

Observations by NASA's Hubble Space Telescope are showing that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse's surface.

NASA’s Webb Telescope is an International Endeavor

The James Webb Space Telescope is an international endeavor with widespread global contributions and experts in more than a dozen countries dedicated to the build, launch, and future science of this flagship NASA space observatory. The cooperation and collaboration on Webb is an incredible testament to what is possible with worldwide teamwork.

NASA’s Planet Hunter Completes Its Primary Mission

NASA's TESS has completed its primary mission, imaging about 75% of the starry sky during a two-year-long survey. TESS has found 66 new planets, nearly 2,100 candidates, and much more.
