The Crab Nebula Seen in New Light by NASA's Webb

Space Telescope Science Institute (STScI) — Mon, 30 Oct 2023 16:05:56 EST

Although the Crab Nebula is one of the most well-studied supernova remnants, questions about its progenitor and the nature of the explosion that created it still remain unanswered. NASA's James Webb Space Telescope is on the case as it sleuths for any clues that remain within the supernova remnant. Webb's infrared sensitivity and spatial resolution are offering astronomers a more comprehensive understanding of the still-expanding scene.

NASA's Webb Captures an Ethereal View of NGC 346

Space Telescope Science Institute (STScI) — Tue, 10 Oct 2023 10:05:57 EST

Within a neighboring dwarf galaxy known as the Small Magellanic Cloud (SMC) lies a dramatic region of star birth - NGC 346, shown here. As the brightest and largest star-forming region in the SMC, it has been studied intensely by a variety of telescopes. NASA's Hubble Space Telescope showed a visible-light view filled with thousands of stars. More recently, NASA's James Webb Space Telescope offered a near-infrared vista highlighting both cool and warm dust. Now, Webb has turned its mid-infrared gaze to NGC 346, revealing streamers of gas and dust studded with bright patches filled with young protostars.

Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b

Space Telescope Science Institute (STScI) — Mon, 11 Sep 2023 10:15:25 EST

Carbon-bearing molecules have been discovered in the atmosphere of the habitable zone exoplanet K2-18 b by an international team of astronomers using data from the NASA's James Webb Space Telescope. These results are consistent with an exoplanet that may contain ocean-covered surface underneath a hydrogen-rich atmosphere. This discovery provides a fascinating glimpse into a planet unlike anything else in our Solar System, and raises interesting prospects about potentially habitable worlds elsewhere in the Universe.

Space Telescope Science Institute (STScI) — Tue, 30 May 2023 11:10:38 EST

Enceladus--a tiny, icy moon of Saturn--is one of the most intriguing objects in the search for signs of life beyond our own planet.

Hubble Monitors Changing Weather and Seasons at Jupiter and Uranus

Space Telescope Science Institute (STScI) — Thu, 23 Mar 2023 10:00:37 EST

New pictures of Jupiter and Uranus from Hubble reveal complex weather activities on these remote gas giant planets. The forecast for Jupiter is blustery winds, while the outlook for Uranus is smoggy as northern summer approaches.

Space dust as Earth's sun shield

University of Utah — Wed, 08 Feb 2023 14:00:00 EST

Dust launched from the moon's surface or from a space station positioned between Earth and the sun could reduce enough solar radiation to mitigate the impacts of climate change.

The canyons on Pluto's moon, Charon, may have formed from the freezing of an internal ocean

Southwest Research Institute — Tue, 07 Feb 2023 17:00:28 EST

"A combination of geological interpretations and thermal-orbital evolution models implies that Charon had a subsurface liquid ocean that eventually froze," said SwRI's Dr. Alyssa Rhoden, a specialist in the geophysics of icy satellites, particularly those containing oceans, and the evolution of giant planet satellite systems.

Webb Detects Extremely Small Main Belt Asteroid

Space Telescope Science Institute (STScI) — Mon, 06 Feb 2023 10:05:18 EST

An asteroid roughly the size of Rome's Colosseum -- between 300 to 650 feet (100 to 200 meters) in length -- has been detected by an international team of European astronomers using NASA's James Webb Space Telescope. The object, shown in this artist's conception, is likely the smallest observed to date by Webb. The detection was serendipitous -- the asteroid was found in calibration images of a different asteroid. The lucky finding suggests Webb can detect many such objects.

MSU expert helps NASA discover new planet that could support life

Michigan State University — Tue, 10 Jan 2023 13:55:55 EST

Working with data from NASA's Transiting Exoplanet Survey Satellite, or TESS, Michigan State University has helped discover an Earth-sized exoplanet -- a planet outside of our solar system.

ALMA and JWST Reveal Galactic Shock is Shaping Stephan's Quintet in Mysterious Ways

National Radio Astronomy Observatory — Mon, 09 Jan 2023 13:15:00 EST

Shockwaves resulting from the violent collision between an intruder galaxy and Stephan's Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST) have revealed that a sonic boom several times the size of the Milky Way has kickstarted a recycling plant for warm and cold molecular hydrogen gas. What's more, scientists uncovered the break-up of a giant cloud into a fog of warm gas, the possible collision of two clouds forming a splash of warm gas around them, and the formation of a new galaxy. The observations were presented today in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.

Largest Potentially Hazardous Asteroid Detected in Eight Years

Association of Universities for Research in Astronomy (AURA) — Mon, 31 Oct 2022 12:00:00 EST

Twilight observations with the US Department of Energy-fabricated Dark Energy Camera at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF's NOIRLab, have enabled astronomers to spot three near-Earth asteroids (NEA) hiding in the glare of the Sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object that is potentially hazardous to Earth to be discovered in the last eight years.
