1/2 This spectacular image, taken by Cassini spacecraft on 24 Dec. 2011, shows one of the largest & longest lived storms ever recorded in our Solar System. The cloud formation, in the northern hemisphere of Saturn, was first seen in late 2010. #scritturebrevi #VentagliDiParole

It looks like someone painted the sky with a mix of chaos and beauty in this breathtaking image released 12 July 2023 on NASA Webb Telescope Telescope's first anniversary of first images revealed. The image displays only a tiny region of the Rho Ophiuchi cloud complex, which, located

Breathtaking timelapse, from Maciej Libert, showing Comet C/2020 F3 (NEOWISE) with noctilucent clouds. Comet  NEOWISE is a long period comet discovered on 27 March 2020, during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope. Its orbital

This mind-blowing composite features the northern part of Saturn's disk (upper left) as seen through Titan's upper dense atmosphere. The dark lines are shadows cast upon the gas giant by its rings. The composite's images were captured by Cassini less than 20 minutes after its

This Hubble image shows UGC 12591, classified as an S0/Sa type isolated galaxy. It is a giant, hybrid-morphology galaxy, i.e. belonging to an intermediate typology between a lenticular (denoted S0) and a spiral (denoted Sa). The galaxy spins at about 500 km/s, the highest

How wonderful! You're seeing a photo of the lit face of Saturn's B-ring, which was taken 25 Aug. 1981 by Voyager 2 from a distance of 743,000 km, one day before the spacecraft's closest approach to the ringed planet. The structure's complexity of the B-ring, with its multiple

Happy birthday to Edward Witten (born August 26, 1951), one of my idols ever. He is universally recognized as one of the most influential theoretical physicists of our time that has made fundamental contributions in various fields of theoretical physics and mathematics. This

1/2 Astrophotographer Dandan Huang captured this bright and green fireball, on 12 Aug 2018 above a valley in Yichang (Hubei, China), as it moved speedily across the sky. The Red Planet appears on the lower left. Given the day when the photo was taken, probably the fireball was

1/2 NASA Webb Telescope just released this breathtaking mosaic of images featuring NGC 1333, a reflection nebula and a young region of very active star formation, located roughly 960 ly away in the Perseus molecular cloud. A research team, led by Adam Langeveld from Johns Hopkins

1/2 I've written about NGC 346 in the past, but I couldn't leave out this new gem, recently released by Hubble, that gives us a unique ultraviolet view. Observations in ultraviolet light are useful because they help researchers understand more about star formation and evolution.

What an amazing movie! You are seeing the surface of the Sun through the "eyes" of the Daniel K. Inouye Solar Telescope (DKIST), which produced the highest resolution observations ever made. The turbulent gas covering the entire Sun appears "to boil" into cell-like structures,

1/2 Here is SS 433, the first discovered microquasar. It is about an exotic star system, consisting of a stellar-mass black hole (BH) and its companion, a giant star. The star is about 30 solar masses, the BH about 10 to 20. The two objects orbit each other with a period of 13

1/2 A JWST near- and mid-IR imaging survey, using NIRCam and MIRI, has taken this recently released image of I Zwicky 18 (I Zw 18), a dwarf irregular galaxy with starburst regions, which is located some 59 Myr away. In the image, I Zw 18 hosts a luminous region (surrounded by

Mind officially blown

1/2 Here is another Hubble gem! This image, released in 2023, features Z 229-15, one of the most interesting cosmic objects due to its multifaceted nature. In fact, it is defined as a ring galaxy, as an active galactic nucleus (AGN), as a quasar, and as a Seyfert galaxy...all

1/3 Exceptional! You're looking at the JWST’s wide-field view* of the massive galaxy cluster MACS-J0417.5-1154, known for its impressive gravitational lensing effects and complex merging dynamics. MACS-J0417.5-1154, located some 4.65 billion light-years away in the

On THURSDAY, SEPTEMBER 12, at 5:30PM Eastern Time, I'll be giving an in-person talk at the Philadelphia Museum of Art (Philadelphia Museum of Art ) on: "The Quest for Cosmic Life." philamuseum.org/calendar/event…

1/2 2024 RW1 was a small asteroid (roughly 1 meter in diameter), discovered in the first hours of 4 September 2024 by Jacqueline B. Fazekas from the Catalina Sky Survey at Mount Lemmon Obs. 2024 RW1 hit the Earth's atmosphere and burned up harmlessly the same day, at around
