NASA’s Webb Hints at Possible Atmosphere Surrounding Rocky Exoplanet
Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside…
Former NASA Center Director, Scientist to Receive Presidential Medals
President Joe Biden will present Dr. Ellen Ochoa, former center director and astronaut at the agency’s Johnson Space Center in Houston, and Dr. Jane Rigby, senior project scientist for NASA’s James Webb Space Telescope, each with the Presidential Medal of…
NASA’s Webb Maps Weather on Planet 280 Light-Years Away
An international team of researchers has successfully used NASA’s James Webb Space Telescope to map the weather on the hot gas-giant exoplanet WASP-43 b. Precise brightness measurements over a broad spectrum of mid-infrared light, combined with 3D climate models and…
Webb Captures Top of Iconic Horsehead Nebula in Unprecedented Detail
NASA’s James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show the top of the “horse’s mane” or…
NASA’s Webb Probes an Extreme Starburst Galaxy
Amid a site teeming with new and young stars lies an intricate substructure. A team of astronomers has used NASA’s James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation…
That Starry Night Sky? It’s Full of Eclipses
Our star, the Sun, on occasion joins forces with the Moon to offer us Earthlings a spectacular solar eclipse – like the one that will be visible to parts of the United States, Mexico, and Canada on April 8. But…
Cheers! NASA’s Webb Finds Ethanol, Other Icy Ingredients for Worlds
Editor’s Note: This article was updated March 13, 2024, to clarify the likelihood that chemicals found around IRAS 2A were present in the first stages of development of our solar system. What do margaritas, vinegar, and ant stings have in…
NASA’s Roman Team Selects Survey to Map Our Galaxy’s Far Side
NASA’s Nancy Grace Roman Space Telescope team has announced plans for an unprecedented survey of the plane of our Milky Way galaxy. It will peer deeper into this region than any other survey, mapping more of our galaxy’s stars than…
NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists
NASA’s Hubble and James Webb Space Telescope have tag-teamed to produce definitive measurements of the universe's expansion rate.
Peering Into the Tendrils of NGC 604 with NASA’s Webb
The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA’s James Webb Space…
What Are Hubble and Webb Observing Right Now? NASA Tool Has the Answer
It’s not hard to find out what NASA’s Hubble and James Webb space telescopes have observed in the past. Barely a week goes by without news of a cosmic discovery made possible using images, spectra, and other data captured by NASA’s…
Webb Unlocks Secrets of One of the Most Distant Galaxies Ever Seen
Looking deeply into space and time, two teams using NASA’s James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Initially detected with NASA’s Hubble…
Webb Finds Evidence for Neutron Star at Heart of Young Supernova Remnant
NASA’s James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at…
NASA Astronomer Sees Power in Community, Works to Build More
Science is often portrayed as a solitary affair, where discoveries are made by lone geniuses toiling in isolation. But Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says solving problems with the people around…
What is Dark Energy? Inside our accelerating, expanding Universe
Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay…
Discovery Alert: A ‘Super-Earth’ in the Habitable Zone
A newly discovered 'super-Earth' dwells in the habitable zone of its parent star – and might have a roughly Earth-sized companion.
NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies
It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes. Only NASA’s…
How NASA Chases and Investigates Bright Cosmic Blips
Stephen Lesage’s phone started vibrating just after halftime on Oct. 9, 2022, while he was watching a soccer game in Atlanta with a friend. When Lesage saw the incoming messages, the match no longer seemed important. There had been a…
