SwRI contributed to new Cycle 1 JWST findings that show the plume of water escaping from Saturn’s moon Enceladus extends 6,000 miles or more than 40 times the moon’s size. In light of this discovery, SwRI’s Dr. Christopher Glein was awarded a NASA JWST Cycle 2 allocation to study the plume as well as the icy surface of Enceladus, to better understand the potential habitability of this ocean world.

A Hubble Space Telescope image of the globular star cluster, Messier 4. The cluster is a dense collection of several hundred thousand stars. Astronomers suspect that an intermediate-mass black hole, weighing as much as 800 times the mass of our Sun, is lurking, unseen, at its core. Credits: ESA/Hubble, NASA

This image of the dusty debris disk surrounding the young star Fomalhaut is from Webb’s Mid-Infrared Instrument (MIRI). It reveals three nested belts extending out to 14 billion miles (23 billion kilometers) from the star. The inner belts – which had never been seen before – were revealed by Webb for the first time. Labels at left indicate the individual features. At right, a great dust cloud is highlighted and pullouts show it in two infrared wavelengths: 23 and 25.5 microns. Credits: NASA, ESA, CSA, A.

New modeling shows that there likely is an ocean layer in four of Uranus’ major moons: Ariel, Umbriel, Titania, and Oberon. Salty – or briny – oceans lie under the ice and atop layers of water-rich rock and dry rock. Miranda is too small to retain enough heat for an ocean layer. Credit: NASA/JPL-Caltech

This illustration depicts asteroid Phaethon being heated by the Sun. The asteroid’s surface gets so hot that sodium inside Phaethon’s rock likely vaporizes and vents into space, causing it to brighten like a comet and form a tail.

Members of NASA’s OSIRIS-REx curation team work with a glove box at the agency's Johnson Space Center in Houston. The curation team will be among the first to see and handle the sample OSIRIS-REx is returning from asteroid Bennu. They are also responsible for storing and distributing the sample to science team members around the world. Most of the sample will be stored for future generations.

NASA’s Curiosity Mars rover captured these “sun rays” shining through clouds at sunset on Feb. 2, 2023, the 3,730th Martian day, or sol, of the mission. It was the first time that sun rays, also known as crepuscular rays, have been viewed so clearly on Mars. Credit: NASA/JPL-Caltech/MSSS

This artist's illustration shows how the gravity of a foreground white dwarf star warps space and bends the light of a distant star behind it. Astronomers using NASA's Hubble Space Telescope have for the first time directly measured the mass of a single, isolated white dwarf (the surviving core of a burned-out Sun-like star) – due to this optical trick of nature. The greater the temporary, infinitesimal deflection of the background star's image, the more massive the foreground star is. (This deviation is so small that it is equivalent to observing an ant crawl across the surface of a quarter from 1,500 miles away.) Researchers found that the dwarf is 56 percent the mass of our Sun. This effect, called gravitational lensing was predicted as a consequence of Einstein's theory of general relativity from a century ago. Observations of a solar eclipse in 1919 provided the first experimental proof for general relativity. But Einstein didn't think the same experiment could be done for stars beyond our Sun because of the extraordinary precision required.
