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.

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

The Hubble Space Telescope has captured an image of an object in the ultraviolet part of the spectrum, which appears similar in size to our Milky Way. Researchers have been puzzled by this object for some time, but recently found similarities between it and a nearby galaxy known as IC 5249, which lacks a bulge and is observed edge-on. The images in ultraviolet and visible light of both objects are strikingly similar and suggest that the object could be a galaxy without a bulge viewed edge-on. Credit for the images goes to HST.

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.

The Hubble Space Telescope has captured images of gas-and-dust disks around the young star TW Hydrae. These images show shadows moving across the disks surrounding the system. Scientists believe that these shadows are being cast by inner disks that are slightly tilted and blocking the light from reaching the outer disk. This tilt is due to the gravitational pull of unseen planets that are changing the structure of the disks.
