☆ Astronomers surprised to find planet 'too massive for its star'
▼ + stars: | 2023-12-01 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

[1/2] An undated handout image shows an artistic rendering of the mass comparison of the star LHS 3154 and its planet LHS 3154b, and our own Earth and Sun. The mass ratio of this planet with its star is more than 100 times greater than that of Earth and the sun. "We discovered a planet that is too massive for its star," said Penn State astronomer Suvrath Mahadevan, one of the leaders of the study published this week in the journal Science. The planet, called LHS 3154 b, orbits at about 2.3% of Earth's orbital distance from the sun, circling its star every 3.7 days. So a very low mass star should have a disk that is also low mass.

☆ Ukraine and the US are mixing weapon systems that weren't built to play together to up Kyiv's defenses, and apparently they work

They've seen success in using US missiles with Buk-M1 systems and HARM missiles on Soviet fighter jets. AdvertisementWith its air defenses working overtime to defend against constant Russian strikes, Ukraine is working with the US to create new capabilities by cobbling together Western and Soviet systems that weren't built to play together. Reporting earlier this year indicated Ukraine had found ways to modify the Soviet Buk air defenses to fire the RIM-7. The US and its Western allies have offered Ukraine air defenses like Patriot batteries, IRIS-T, NASAMs, and Gepard anti-aircraft guns, but Ukrainian forces continue to operate a number of Soviet air defenses, the Buk and the S-300 being among the most prominent. AdvertisementThe new capability was promising for Ukraine and indicated future modifications to its Soviet systems could be made, like firing US missiles from Soviet Buk vehicles, which are self-propelled, mid-range surface-to-air missile systems.

Those Big East titles, automatic. Neptune's second season has all the potential to not only surpass his first one, but to stake the No. A big season from Moore -- who has plenty to prove to NBA scouts -- should mean a big season for Villanova. THE SCHEDULELong the dominant team in the Big East, the Wildcats are again looking up. There are games against Maryland, a potential matchup with North Carolina at the Battle 4 Atlantis tournament, Kansas State and UCLA on the slate before Big East play.

CNN —A 22-year-old German man has been detained in Florence accused of damaging a statue in the 16th-century Fountain of Neptune in the Piazza della Signoria, city authorities said in a statement. The city estimates the damage to the statue is around €5,000 ($5,400). The fountain features a statue of the Roman sea god Neptune atop a shell-shaped carriage pulled by horses. The mayor of Florence tweeted a photo of the 22-year-old German tourist, whose face was blurred, posing on the 16th-century Fountain of Neptune in Piazza della Signoria in Florence. In August, German tourists were accused of spray-painting soccer graffiti on a wall of the historic Vasari Corridor nearby.

☆ Neptune’s disappearing clouds linked to solar cycle
▼ + stars: | 2023-08-22 | by ( Kristen Rogers | ) edition.cnn.com time to read: +6 min

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.

The deal fits the Italian group's plan to increase the share of gas in its total hydrocarbon production and is expected to boost its earnings immediately, Eni said in a statement. Eni, which is controlled by the Italian government, owns 63% of Vaar and is the main beneficiary of cash dividends from the Oslo-listed unit. VAAR EXPANDING IN NORWAYUnder the agreement, Eni will acquire Neptune's entire portfolio other than its operations in Germany and Norway. The German operations will be carved out prior to the Eni transaction and the Norwegian operations will be acquired by Vaar directly from Neptune in a separate deal, the two groups said in a statement. The Vaar transaction will close immediately prior to the Eni deal with the proceeds from the Norway sale remaining with the business purchased by the Italian group.

Two little-known US intelligence agencies have made significant contributions to countering Russia in Ukraine. The National Geospatial-Intelligence Agency and the National Reconnaissance Office have gathered and distributed valuable information about Russian activity.

US Air Force/Senior Airman Ian DudleyThe US response to Russia's war in Ukraine has pulled the National Geospatial-Intelligence Agency (NGA) and the National Reconnaissance Office out of the shadows. NRO satellites have many customers, but the NGA is probably the most reliant on the satellites operated by the NRO.

☆ In its first 100 days, the James Webb telescope peered deep into space, took beauty shots of faraway galaxies and glittering nebula, and saw a spacecraft slam into an asteroid

In its first 100 days of observation, Webb has captured mind-blowing images, reaching astonishing cosmic distances. Webb captured violent interactions in a star system more than 5,000 light years awayWebb captured a series of 17 concentric dust rings spawned by the Wolf-Rayet 140 binary system. Webb took a 'deep field' image that filled astronomers with wonderThe James Webb Space Telescope's first deep field infrared image, released on July 11, 2022. Webb captured detailed views of the king of our solar system – JupiterWide-field view of Jupiter, captured by Webb. Webb snapped a beauty shot of the Carina NebulaThe star-forming region NGC 3324 in the Carina Nebula, captured in infrared by Webb.

The observatory's views, released Wednesday, include rare looks at Neptune's rings, providing some of the sharpest images of these ghostly features seen in more than 30 years, according to NASA. I ugly-cried when I saw THE FIRST JWST NEPTUNE IMAGES!" The images are the first that have been taken of Neptune's rings at infrared wavelengths, which can pierce through dust and gas that might otherwise obscure celestial targets. The Webb telescope's infrared instruments allow it to see planets, stars and galaxies beyond the range of human sight and other telescopes that see primarily in visible light. Along with its bright rings, the Webb observatory spied Neptune's fainter dust bands and seven of the planet's 14 known moons.

☆ Saturn's gravitational pull shredded an ancient moon, creating its iconic rings and unusual tilt, new research suggests

New models suggest Saturn's gravity shredded a moon, Chrysalis, about 160 million years ago. The ancient moon could explain two long-standing mysteries: Saturn's iconic rings and dramatic tilt. Cassini captured five of Saturn's moons in a single frame, on July 29, 2011. Saturn's rings display their subtle colors in this view captured by NASA's Cassini spacecraft, on August 22, 2009. NASA/JPL-Caltech/Space Science InstitutePlanetary scientists have long suspected Saturn's tilt may have come from gravitational interactions with Neptune.
