NASA’s James Webb Space Telescope Completes Comprehensive Systems Test

07.13.2020
Now that NASA’s James Webb Space Telescope has been assembled into its final form, testing teams seized the unique opportunity to perform a critical software and electrical analysis on the entire observatory as a single, fully connected vehicle.

Hubble Sees Sculpted Galaxy

07.10.2020
Captured by the Hubble Space Telescope, this image shows NGC 7513, a barred spiral galaxy. This galaxy is moving at the astounding speed of 972 miles per second, and it is heading away from us.

Two Bizarre Brown Dwarfs Found With Citizen Scientists’ Help

07.10.2020
With the help of citizen scientists, astronomers have discovered two highly unusual brown dwarfs, balls of gas that are not massive enough to power themselves the way stars do.

Hubble Spots Feathered Spiral

07.02.2020
NGC 2275 is classified as a flocculent (or fluffy-looking) spiral galaxy, located 67 million light-years away in the constellation of Cancer. Millions of bright, young, blue stars shine in the complex, feather-like spiral arms, interlaced with dark lanes of dust.

NASA’s TESS Delivers New Insights Into an Ultrahot World

06.30.2020
KELT-9 b is one of the hottest planets known. New measurements from NASA's Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of this bizarre world.

Hubble Captures Galaxy on Edge

06.26.2020
We don’t see the beautiful spiral arms of galaxy NGC 5907 in this Hubble image because we are viewing it edge-on, like looking at the rim of a plate. It is for this reason that NGC 5907 is also known as the Knife Edge galaxy.

Hubble Sees Cosmic Flapping ‘Bat Shadow’

06.25.2020
NASA’s Hubble Space Telescope observed a young star’s unseen, planet-forming disk casting a huge shadow across a more distant cloud in a star-forming region – like a fly wandering into a flashlight beam shining on a wall. The feature was dubbed the “Bat Shadow” because it resembles a pair of wings. Now, scientists see the Bat Shadow flapping!

NASA’s TESS, Spitzer Missions Discover a World Orbiting a Unique Young Star

06.24.2020
Astronomers using data from NASA's TESS and retired Spitzer Space Telescope have discovered a planet as large as Neptune circling the young star orbiting AU Microscopii.

Mapping the Early Universe with NASA's Webb Telescope

06.24.2020
Although many other observatories, including NASA's Hubble Space Telescope, have previously created "deep fields" by staring at small areas of the sky for significant chunks of time, the Cosmic Evolution Early Release Science (CEERS) Survey, led by Steven L. Finkelstein of the University of Texas at Austin, will be the first for Webb.

Young Giant Planet Offers Clues to Formation of Exotic Worlds

06.22.2020
Jupiter-size planets orbiting close to their stars have upended ideas about how giant planets form. Finding young members of this planet class could help answer key questions.

Hubble Provides Holistic View of Stars Gone Haywire

06.18.2020
As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Hubble has dissected such crazy fireworks in two nearby young planetary nebulas.

Hubble Makes a Bright Find

06.16.2020
Seen here in incredible detail, thanks to the NASA/ESA Hubble Space Telescope, is the starburst galaxy formally known as PLCK G045.1+61.1. The galaxy, which appears as multiple reddish dots near the center of the image, is being gravitationally lensed by a cluster of closer galaxies, also seen in the image.

Hubble Glimpses a Galaxy Among Many

06.12.2020
Looking deep into the universe, the Hubble Space Telescope catches a passing glimpse of the numerous arm-like structures that sweep around this barred spiral galaxy, known as NGC 2608. Appearing as a slightly stretched, smaller version of our Milky Way, the peppered blue and red spiral arms are anchored together by the prominent horizontal

Gravity Assist: Puffy Planets, Powerful Telescopes, with Knicole Colon

06.12.2020
NASA astrophysicist Knicole Colon describes her work on the Kepler, Hubble, TESS and Webb missions, and takes us on a tour of some of her favorite planets.

Tower Extension Test a Success for NASA’s James Webb Space Telescope

06.09.2020
To test the James Webb Space Telescope’s readiness for its journey in space, technicians successfully commanded it to deploy and extend a critical part of the observatory known as the Deployable Tower Assembly.

Hubble Catches Cosmic Snowflakes

06.05.2020
The stars of the globular cluster NGC 6441 sparkle peacefully in the night sky, about 13,000 light-years from the Milky Way’s galactic center.

Hubble Makes Surprising Find in Early Universe

06.03.2020
the formation of the first stars and galaxies in the early universe took place sooner than previously thought, suggest new Hubble results. A European team of astronomers have found no evidence of the first generation of stars, known as Population III stars, as far back as when the universe was just 500 million years old.

Intense Flash From Milky Way's Black Hole Illuminated Gas Far Outside of Our Galaxy

06.02.2020
About 3.5 million years ago, the supermassive black hole at the center of our Milky Way galaxy unleashed an enormous burst of energy. Now, eons later, astronomers are using NASA's Hubble Space Telescope's unique capabilities to uncover even more clues about this cataclysmic explosion.

NASA’s Webb Telescope is an International Endeavor

06.01.2020
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.

Hubble Grabs a Stellar Latte

05.29.2020
Far away in the Ursa Major constellation is a swirling galaxy that would not look out of place on a coffee made by a starry-eyed barista. NGC 3895 is a barred spiral galaxy that was first spotted by William Herschel in 1790 and was later observed by the Hubble Space Telescope.

In Planet Formation, It's Location, Location, Location

05.28.2020
Astronomers using NASA's Hubble Space Telescope are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2.

Hubble Sees Stellar Glitter in a Cosmic Void

05.22.2020
Unlike a spiral or elliptical galaxy, the galaxy KK 246 looks like glitter spilled across a black velvet sheet. KK 246, also known as ESO 461-036, is a dwarf irregular galaxy residing within the Local Void, a vast region of empty space. This lonely galaxy is the only one known for certain to reside in this enormous volume.

NASA’s Webb Will Study the ‘Building Blocks’ of Our Solar System

05.21.2020
With James Webb, researchers will observe far-flung asteroids, some with moons, to learn more about the makeup and history of our solar system.
