Cassini Spacecraft And Ground Telescope See Violent Saturn Storm

Source:  NASA RELEASE: 11-151

Excerpt:  ...NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope tracked the growth of a giant early-spring storm in Saturn's northern hemisphere so powerful it stretches around the entire planet. The rare storm has been wreaking havoc for months and shot plumes of gas high into the planet's atmosphere. ...The storm produced a 3,000-mile-wide (5,000-kilometer-wide) dark vortex, possibly similar to Jupiter's Great Red Spot, within the turbulent atmosphere. "Nothing on Earth comes close to this powerful storm," says Leigh Fletcher, the study's lead author....  See alsowww.nasa.gov/home/hqnews/2011/jul/HQ_11-220_Cassini_Big_Storm.html

Early universe’s ‘little red dots’ may be black hole stars

By -
By Daniel Clery , Science.  Excerpt: It’s as if the baby universe had caught a case of measles. Since NASA’s JWST observatory began peering into the distant universe in 2022, it has discovered a rash of “little red dots”—hundreds of them, shining within the first billion years of the 13.8-billion-year-old universe, so small and red that they defied conventional explanation. Only in the past few months has a picture begun to emerge. The little red dots, astronomers say, may be an entirely new type of object: a colossal ball of bright, hot gas, larger than the Solar System, powered not by nuclear fusion, but by a black hole. ...JWST couldn’t resolve the dots into a recognizable shape, which meant they must have been tiny—less than 2% of the diameter of the Milky Way....  Full article at https://www.science.org/content/article/early-universe-s-little-red-dots-may-be-black-hole-stars .

The Moon Was an Inside Job

By Robin George Andrews , The New York Times.  Excerpt: New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun. ...A study published Thursday in the journal  Science  ...looking at chemical clues hidden in Earth’s rocks, meteorites and moon matter, scientists have found ghostly remnants of Theia. And they show that Theia and the early Earth were built from the same construction materials....  Full article at https://www.nytimes.com/2025/11/20/science/moon-collision-earth-theia.html .

The Vera Rubin Observatory is ready to revolutionize astronomy

By -
By Lisa Grossman , Science News.  Excerpt: Perched on a high, flat-topped mountain called Cerro Pachón, the Rubin Observatory ...can investigate some of the universe’s slowest, most eternal processes, such as the assembly of galaxies and the expansion of the cosmos. And by mapping the entire southern sky every couple of nights, it can track some of the universe’s fastest and most ephemeral events, including exploding stars and  visits from interstellar comets . ...Rubin data will be made available online to anyone in the world, from professional astronomers to elementary school students. ...the observatory has what’s now the  largest digital camera ever built ...at 1.65 meters wide...It combines 189 individual CCDs...roughly the same number of pixels as 260 smartphone cameras. ...In June, the telescope hit another big milestone:  releasing Rubin’s first images  to the public. ...the Rubin team shared videos made up of hundreds of individual images from...
