As a NASA astronaut, Mike Massimino spacewalked four times to repair the Hubble Space Telescope. When he retired in 2014 and began giving talks about his experiences, he assumed audiences would want to hear about the thrills of those exploits. Instead, he found himself fielding questions that were broader and deeper: How did he weather disappointments? Why didn’t he give up when NASA rejected him three times before accepting him? “The space stories just help them remember the takeaways, the lessons I learned from making mistakes.”

But Webb has obtained even better data on galaxies a bit further along in development. The gas detected in star-forming regions - stellar nurseries - of teenage galaxies was much hotter, at about 24,000 degrees Fahrenheit (13,350 degrees Celsius), than observed in galaxies today. The galaxies were observed glowing with eight elements - hydrogen, helium, oxygen, nitrogen, sulfur, argon, nickel and silicon. Incidentally, oxygen is also the third-most abundant element in the universe (behind hydrogen and helium)," Strom said. The new study presents the first results from the CECILIA Survey that uses Webb to scrutinize the chemistry of distant galaxies.

New details of the celestial feature have emerged in the colorful image, which unites the observational powers of Hubble Space Telescope in visible light and the James Webb Space Telescope in infrared light, which is invisible to the human eye. Hubble has long been used to search for faint, distant galaxies across different wavelengths of light. This cosmic effect occurs when closer objects — such as the galactic clusters — act like a magnifying glass for distant objects. The Webb and Hubble composite image includes "Mothra," a star system magnified by the galactic cluster pair as well as another unseen object. NASA/ESA/CSA/STScIThe team nicknamed the star system Mothra due to its extreme magnification and brightness.

PARIS, Nov 7 (Reuters) - European astronomers on Tuesday released the first images from the newly launched Euclid space telescope, designed to unlock the secrets of dark matter and dark energy - hidden forces thought to make up 95% of the universe. Scientists believe vast, seemingly organised structures such as Perseus could only have formed if dark matter exists. "The rest of the universe we call dark because it doesn't produce light in the normal electromagnetic spectrum. Tell-tale signs of the hidden force exerted by dark matter include galaxies rotating more quickly than scientists would expect from the amount of visible matter that can be detected. We think there's lots of dark matter in that cluster and pulling these galaxies together," she added.

CAPE CANAVERAL, Fla. (AP) — Scientists on Tuesday unveiled the first pictures taken by the European space telescope Euclid, a shimmering and stunning collection of galaxies too numerous to count. The photos were revealed by the European Space Agency, four months after the telescope launched from Cape Canaveral. Although these celestial landscapes have been observed before by the Hubble Space Telescope and others, Euclid's snapshots provide "razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant universe," the agency said. In one picture, Euclid captured a group shot of 1,000 galaxies in a cluster 240 million light-years away, against a backdrop of more than 100,000 galaxies billions of light-years away. Although the Hubble Space Telescope previously observed the heart of this galaxy, Euclid’s shot reveals star formation across the entire region, scientists said.

☆ Webb telescope spots never-before-seen jet stream in Jupiter’s atmosphere
▼ + stars: | 2023-10-24 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

The astronomers spied a high-speed jet stream in Jupiter’s lower stratosphere, an atmospheric layer about 25 miles (40 kilometers) above the clouds. “What we have always seen as blurred hazes in Jupiter’s atmosphere now appear as crisp features that we can track along with the planet’s fast rotation,” he said. Jet stream revelationsResearchers compared winds detected by Webb at high altitudes with those within the lower layers picked up by Hubble and tracked changes in wind speed. Both space observatories were necessary to detect the jet stream, as Webb spotted small cloud features and Hubble provided a look at the equatorial atmosphere, including storms not related to the jet. Future observations of Jupiter using the Webb telescope may uncover more insights into the jet stream, such as whether its speed and altitude shift over time, as well as other surprises.

"We concluded that the largest marsquake seen by InSight was tectonic, not an impact. "Most of the marsquakes we've detected thus far have been associated with a region called Cerberus Fossae, located eastward of InSight. The energy it released surpassed the cumulative energy from all the other marsquakes InSight recorded. With future human missions to Mars in mind, a greater understanding of Martian seismic activity is pertinent. Charalambous said the location of the majority of the marsquakes detected by InSight remained uncertain, with a poor understanding of the mechanisms that triggered them.

CNN —A building block of life may exist inside the global ocean on Europa, one of Jupiter’s icy moons. Scientists have long questioned whether Europa’s ocean contained carbon and other chemicals necessary for life. Astronomers used the Webb telescope to observe Jupiter's icy moon Europa. Carbon dioxide appears to be concentrated in a region of “chaos terrain” on Europa called Tara Regio. Future observations of Europa with the Webb Telescope could help astronomers determine whether there are other concentrated regions of carbon dioxide on the surface, Trumbo said.

CNN —Astronomers have spotted a large and mysterious dark spot within Neptune’s atmosphere, and it has an unexpectedly bright companion. “Since the first discovery of a dark spot, I’ve always wondered what these short-lived and elusive dark features are,” said lead study author Patrick Irwin, professor of planetary physics at the University of Oxford, in a statement. Gas giants and dark spotsGiant gaseous planets in our solar system, including Neptune, are known for the dark spots that appear in their atmospheres, such as Jupiter’s Great Red Spot, a centuries-old storm. The Great Dark Spot on Neptune, the nickname given to the largest storm witnessed by Voyager 2, was so large that it could contain Earth. The unusual cloud appeared in the observation as a smaller bright spot next to the larger dark spot, and both are on the same atmospheric level.

The findings are “extremely exciting and unexpected, especially since Neptune’s previous period of low cloud activity was not nearly as dramatic and prolonged,” Chavez added. The findings also contradict the idea of the clouds being affected by Neptune’s four seasons, which each last about 40 years. Additionally, Neptune storms rising from the deep atmosphere do influence the planet’s cloud cover — but aren’t related to clouds formed in the upper atmosphere. That variable could interfere with studies looking at correlations between photochemically produced clouds and the solar cycle. More research could also suggest how long the near absence of clouds on Neptune might last.

Earendel was first discovered by the Hubble Space Telescope last year. Webb is 100 times more powerful than Hubble, though, and it captured previously unseen colors of the distant star. Those colors reveal that being the farthest star we've ever detected does not make Earendel lonely — scientists believe it has a companion star beside it. Stars as massive as Earendel do typically have companions, but Hubble was unable to detect one for Earendel. Thanks to the Webb Telescope's powerful infrared vision, though, scientists believe they can see, for the first time, a "cooler, redder companion star" beside Earendel.

CNN —The Hubble Space Telescope captured an unexpected observation of a nearby planet that’s having its atmosphere blasted away by energetic outbursts from its star. As the planet is blasted by radiation, its atmosphere heats to the point that it escapes the planet’s gravity and puffs out into space. The planet gets hit with flares, X-rays and stellar wind, or a charged stream of particles released from the star. “This creates a really unconstrained and frankly, scary, stellar wind environment that’s impacting the planet’s atmosphere,” Rockcliffe said. Astronomers will conduct more follow-up observations of the system with Hubble to track how the planet changes in the future.
