The astronomers were mapping space's background glow of gamma rays, the brightest and most energetic type of light on the electromagnetic spectrum. They were surprised to find way more gamma rays coming from one part of the sky than anywhere else. AdvertisementAn artist's concept shows the entire sky in gamma rays, with the plane of our galaxy across the middle. Magenta circles indicate the area where astronomers found more high-energy gamma rays than average. Some unknown object or process out there in the universe may be producing both the gamma rays and the UHECRs.

☆ ‘Magic islands’ mystery on Saturn’s moon Titan may be solved
▼ + stars: | 2024-01-11 | by ( Ashley Strickland | ) edition.cnn.com time to read: +7 min

CNN —The disappearing “magic islands” on Saturn’s largest moon Titan have intrigued scientists since NASA’s Cassini mission spotted them during flybys a decade ago. Titan, larger than both our moon and the planet Mercury, is the only moon in our solar system with a thick atmosphere. The sea is 50% larger than Lake Superior and is made up of liquid methane, ethane and nitrogen. An artist's illustration shows a lake at the north pole of Saturn's moon Titan, including raised rims spied by Cassini. Liquid methane slowly seeps into the frozen clumps, eventually causing them to disappear from view.

☆ A giant, boiling, shrinking planet has a tail stretching 350,000 miles into space, astronomers discover

Astronomers have nabbed a rare opportunity to watch a planet shrink in real-time. The Jupiter-sized planet, located 160 light years away, is orbiting its host star so closely that the star is boiling the planet's atmosphere. The boiling is so intense, that the world has developed a comet-like tail stretching 350,000 miles behind it, scientists announced on Tuesday. Don't retire on this planetThe planet, called WASP-69b, circles very closely to its star, completing an orbit in under four days. Because it's so large, it takes much longer to lose its atmosphere, giving scientists plenty of time to study it.

☆ NASA mission achieves most distant demo of laser communications across space

CNN —An innovative experiment flying aboard NASA’s Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo was designed to be the US space agency’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser. NASA/JPL-CaltechIt’s not the first time laser communications have been tested in space. The first test of two-way laser communication occurred in December 2021 when NASA’s Laser Communications Relay Demonstration launched and went into orbit about 22,000 miles (35,406 kilometers) from Earth. And the Artemis II spacecraft will use laser communications to return high-definition video of a crewed journey around the moon.

The technological feat, using NASA's Psyche probe, broke new ground for deep space communications. AdvertisementNASA has achieved a world-first after sending a laser-beamed message to Earth from nearly 10 million miles away within 50 seconds. While the space agency has long been able to communicate with spacecraft using radio waves, it had never before been able to send information using lasers from that far into space. The feat, achieved using NASA's Deep Space Optical Communications (DSOC) experiment on board the Psyche spacecraft, could someday allow humans to stream video calls on Mars. The spacecraft then beamed back information using its laser.

☆ NASA scientists think some planets are shrinking because powerful radiation from their cores is pushing away their atmospheres
▼ + stars: | 2023-11-17 | by ( Sebastian Cahill | Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +4 min

Planets beyond our solar system have a size gap, where worlds seem to shrink past a certain range. Scientists think this is because some sub-Neptunes shrink — losing their atmospheres and speeding through the size gap until they are as small as a super-Earth. AdvertisementThe planets themselves may be pushing their atmospheres awayShrinking exoplanets may lack the mass (and therefore the gravity) to hold their atmospheres close. AdvertisementThe other hypothesis, called photoevaporation, says that a planet's atmosphere is dissipated by the radiation of its host star. AdvertisementThe scientists found that most of the planets there retained their atmosphere, making the core-powered mass loss a more likely cause of eventual atmosphere loss.

Eris has a diameter of about 1,445 miles (2,326 km), slightly smaller than Pluto's 1,473 miles (2,370 km). Because of its greater concentration of rock, which is denser than ice, Eris has about 25% more mass than Pluto. "Just like the Earth-moon system, tides on Eris slowly push Dysnomia away and slow down the spin of Eris.

☆ Solar conjunction halts communications between Mars missions and NASA

CNN —Robotic explorers investigating Mars are currently out of touch with space agencies on Earth after hitting a giant communications roadblock. Mission controllers at NASA won’t send any commands to its fleet of orbiters and rovers, including Perseverance and Curiosity, for the next 10 days due to the Mars solar conjunction. During the roughly two-week period, the hot, energized gas continually spewed by the sun from its outer atmosphere can interfere with the radio signals that NASA uses to communicate with its Martian robotic explorers. A Mars solar conjunction occurs every two years when the sun moves between Mars and Earth. The Ingenuity helicopter, which has largely served as the Perseverance rover’s aerial scout, will also lie low and won’t conduct any flights during this time.

Data from NASA's Magellan spacecraft and Pioneer Venus Orbiter is used in an undated composite image of the planet Venus. Its thick and noxious atmosphere is dominated by carbon dioxide - 96.5% - with lesser amounts of nitrogen and trace gases. In fact, with Venus getting far less scientific attention than other planets such as Mars, the direct detection of its oxygen has remained difficult. They noted that this atomic oxygen, which consists of a single oxygen atom, differs from molecular oxygen, which consists of two oxygen atoms and is breathable. "The Venus atmosphere is very dense.

☆ Relics of Huge Primordial Collision Reside in Earth's Deep Interior
▼ + stars: | 2023-11-01 | by ( Nov. | At P.M. | ) www.usnews.com time to read: +4 min

By Will DunhamWASHINGTON (Reuters) - Seismologists have recognized since the 1970s that two mysterious continent-sized blobs reside in the deepest part of Earth's mantle, one under Africa and the other under the South Pacific region. Based on these simulations, they proposed that most of Theia was absorbed into Earth, forming the blobs, while residual debris formed the moon. If the study's conclusions are correct, these blobs would represent the first direct evidence of the hypothesized moon-forming collision. "It is incredible because we can uncover relics of another planet - Theia - if we dig deep enough in Earth's mantle," added planetary scientist and study co-author Hongping Deng of the Chinese Academy of Sciences' Shanghai Astronomical Observatory. Asimow said that if their conclusions are correct some volcanic rocks that reach Earth's surface may provide samples of a vanished planet.
