Hubble Spots a Stunning Spiral

Galaxies come in many shapes and sizes. One of the key galaxy types we see in the universe is the spiral galaxy, as demonstrated in an especially beautiful way by the subject of this Hubble Space Telescope image, NGC 2985. NGC 2985 lies over 70 million light-years from the solar system in the constellation of Ursa Major (the Great Bear).

NASA’s Webb Telescope Shines with American Ingenuity

Sending humans to the Moon is similar to building the worlds most complex and powerful space telescope, the James Webb Space Telescope. Both require surmounting countless hurdles, inventing new technologies while staring into the face of the unknown.

New Hubble Constant Measurement Adds to Mystery of Universe’s Expansion Rate

Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors.

Hubble Peers at Galactic Cherry Blossoms

The galaxy NGC 1156 resembles a delicate cherry blossom tree flowering in springtime in this Hubble image. The many bright "blooms" within the galaxy are in fact stellar nurseries — regions where new stars are springing to life.

Hubble Uncovers Black Hole Disk that Shouldn't Exist

As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

Hubble Watches Stars in Bloom

This Hubble Space Telescope image shows bright, colorful pockets of star formation blooming like roses in a spiral galaxy named NGC 972.

Atmosphere of Mid-Size Planet Revealed by Hubble and Spitzer

Two NASA space telescopes have teamed up to identify, for the first time, the detailed chemical "fingerprint" of a planet between the sizes of Earth and Neptune.

Hubble Captures the Galaxy's Biggest Ongoing Stellar Fireworks Show

Imagine slow-motion fireworks that started exploding 170 years ago and are still continuing. This type of firework is not launched into Earth's atmosphere, but rather into space by a doomed super-massive star called Eta Carinae. A new Hubble view, which includes ultraviolet light, shows its hot, expanding gases glowing in red, white and blue.

Hubble Catches a Bounty of Stars and Cosmic Dust

This Hubble Space Telescope image shows the spiral galaxy Messier 98, which is located about 45 million light-years away in the constellation of Coma Berenices (Berenice's Hair). Messier 98 is estimated to contain about a trillion stars.

NASA’s Webb Telescope Tech Improves Patients’ Vision

The James Webb Space Telescope is scheduled to launch in 2021, but NASA technology developed for this upcoming innovative observatory is already hard at work here on Earth, helping improve LASIK eye surgery.

Hubble Finds Tiny “Electric Soccer Balls” in Space, Helps Solve Interstellar Mystery

Scientists using the Hubble telescope have found electrically-charged molecules in space shaped like soccer balls, shedding light on the mysterious contents of the gas and dust that fills interstellar space.

Hubble Captures Elusive, Irregular Galaxy

IC 10 is a remarkable object. It is the closest-known starburst galaxy, meaning that it is undergoing a furious bout of star formation fueled by ample supplies of cool hydrogen gas.

NASA’s Webb Telescope Will Survey Saturn and its Moon Titan

Hubble Sets Sights on an Explosive Galaxy

When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous — so much so that it forms what looks like an especially bright new star that slowly fades away over time.

NASA's Webb Sunshield Undergoes Rocket Fitting, More Testing

NASA's James Webb Space Telescope’s spacecraft element, which consists of the observatory’s spacecraft bus and the sunshield, was put in the same folded-up configuration that it will be in when mounted on atop a rocket for launch in 2021.

Mature Galaxy Mesmerizes in New Hubble View

NGC 7773 is a beautiful example of a barred spiral galaxy. A luminous bar-shaped structure cuts prominently through the galaxy's bright core, extending to the inner boundary of NGC 7773's sweeping, pinwheel-like spiral arms. Astronomers think that these bar structures emerge later in the lifetime of a galaxy.

How the Webb Telescope Will Explore Mars

When NASA's James Webb Space Telescope, launching in 2021, reaches its destination a million miles from Earth, it will be able to see the whole disk of Mars every two years. If a global dust storm envelops the Red Planet at a time when Webb could see it, the powerful space telescope could gather information about the storm.

Hubble Sees a Galaxy Bucking the Trend

This luminous orb is the galaxy NGC 4621, better known as Messier 59. Located in the 2,000-strong Virgo cluster of galaxies within the constellation of Virgo (the Virgin), Messier 59 lies approximately 50 million light-years away from us.

NASA’s James Webb Space Telescope Emerges Successfully from Final Thermal Vacuum Test

NASA’s James Webb Space Telescope has successfully cleared another critical testing milestone, taking this ambitious observatory one step closer to its 2021 launch.

Hubble Spies Curious Galaxy Moving a Little Closer

This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong.

Galaxy Blazes With New Stars Born From Close Encounter

The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.

10 Years Ago, Hubble’s Final Servicing Mission Made It Better Than Ever

Ten years ago today, astronauts aboard the space shuttle Atlantis launched into space to visit Hubble one last time. During this mission, they would integrate new instruments, repair broken equipment and replace critical components of the famed telescope.

Hubble Peers at an Ancient Galaxy Cluster

Dotted across the sky in the constellation Pictor is this galaxy cluster, one of the farthest observed to cause gravitational lensing.

Hubble Spots Stunning Spiral Galaxy

NGC 2903 is located about 30 million light-years away in the constellation of Leo (the Lion), and was studied as part of a Hubble survey of the central regions of roughly 145 nearby disk galaxies.

NASA Scientist to Discuss “Solving the Puzzles of Planet Formation in the Modern Era of Planet-Hunting” at Library of Congress Lecture

The public is invited to a free talk called Solving the Puzzles of Planet Formation in the Modern Era of Planet-Hunting,' with Elisa Quintana, NASA Astrophysicist. The talk will occur in the Pickford Theater, third floor, Madison Building, 101 Independence Avenue SE, Library of Congress, Washington, D.C., on Thursday, May 9 from 11:30 a.m. to 12:30
