CNN —Astronomers have discovered a “super-Earth,” or a world larger than our planet, orbiting a star about 137 light-years away. The super-Earth exoplanet, known as TOI-715b, orbits a red dwarf star that is cooler and smaller than our sun. “This discovery is exciting as it’s the first super-Earth from TESS to be found within the conservative habitable zone,” Dransfield said. If the Earth-size planet is confirmed, it will become the smallest planet yet that TESS has found in a habitable zone. TOI-715b’s star has only shown a couple of flares within the past two years and isn’t considered active, making it an old star, Dransfield said.

☆ Saturn’s ‘Death Star’ moon is hiding an internal ocean, scientists say
▼ + stars: | 2024-02-07 | by ( Ashley Strickland | ) edition.cnn.com time to read: +6 min

CNN —Astronomers have uncovered additional evidence that one of Saturn’s smallest moons, Mimas, is hiding a global ocean beneath its icy surface. Discovered in 1789 by English astronomer William Herschel as a tiny dot near Saturn, Mimas was first imaged from space by the Voyager probes in 1980. Craters cover the surface of Mimas, but the largest one is 80 miles (about 130 kilometers) across and causes the moon to resemble the Death Star from the “Star Wars” films. But Saturn’s Enceladus appears younger because active geysers have contributed to resurfacing, or depositing of new, fresh material on that moon’s surface. “Mimas certainly demonstrates that moons with old surfaces can be hiding young oceans, which is pretty exciting,” Rhoden said.

CAPE CANAVERAL, Fla. (AP) — Astronomers have found the best evidence yet of a vast, young ocean beneath the icy exterior of Saturn’s Death Star lookalike mini moon. Barely 250 miles (400 kilometers) in diameter, the heavily cratered moon lacks the fractures and geysers — typical signs of subsurface activity — of Saturn’s Enceladus and Jupiter’s Europa.

Co-author Nick Cooper of Queen Mary University of London said the existence of a “remarkably young” ocean of liquid water makes Mimas a prime candidate for studying the origin of life.

"For your typical brown dwarf just traversing the galaxy in solitude, your brown dwarf is very mysterious.

☆ ‘Magic islands’ mystery on Saturn’s moon Titan may be solved

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.

CNN —Astronomers have discovered surprising details about Saturn’s atmosphere, using a new image captured by NASA’s James Webb Space Telescope. In the image, Saturn itself appears extremely dark due to the near-total absorption of sunlight by methane gas. The image was taken with Webb’s Near-Infrared Camera, known as NIRCam, as part of a Webb program that involves several exceptionally deep exposures of Saturn, according to NASA. This latest detailed image comes just weeks after the Webb telescope spotted a record-breaking water plume erupting from Saturn’s moon Enceladus, which feeds Saturn’s diffuse E ring, according to NASA. In the future, additional and deeper exposures from Webb will help astronomers examine fainter rings around Saturn, according to NASA.

☆ Saturn's icy moon Enceladus harbors essential elements for life

The discovery was based on data collected by NASA's Cassini spacecraft, the first to orbit Saturn, during its 13-year landmark exploration of the gaseous giant planet, its rings and its moons from 2004 to 2017. The same team previously confirmed that Enceladus' ice grains contain a rich assortment of minerals and complex organic compounds, including the ingredients for amino acids, associated with life as scientists know it. Another is Jupiter's larger moon Europa, which also is believed to harbor a global ocean of liquid water beneath its icy surface. "This key ingredient could be abundant enough to potentially support life in Enceladus' ocean," said co-investigator Christopher Glein, a planetary scientist at Southwest Research Institute in San Antonio, Texas. "Whether life could have originated in Enceladus' ocean remains an open question," Glein said.

CNN —A key chemical building block of life has been found on Saturn’s moon Enceladus. An ocean exists beneath the thick, icy surface of Enceladus, and plumes of material regularly release from geysers at the moon’s south pole. “Previous geochemical models were divided on the question of whether Enceladus’ ocean contains significant quantities of phosphates at all,” Postberg said. “This key ingredient could be abundant enough to potentially support life in Enceladus’ ocean; this is a stunning discovery for astrobiology.”Some of the additional ocean world moons around Jupiter and Saturn include Europa, Titan and Ganymede. Although the building blocks of life and conditions for habitability exist on Enceladus, no actual life has been detected yet.

Enceladus — the sixth-largest of Saturn’s 146 moons — has a liquid ocean with a rocky floor under its bright, white and frosty surface. They found them using data from Cassini, a joint NASA-European orbiter that concluded its study of Saturn, its rings and moons in 2017. The results, which add to the prospect that Enceladus is home to extraterrestrial life, were published on Wednesday in the journal Nature. Phosphorus is a key ingredient in human bones and teeth, and scientists say it is the rarest bio-essential ingredient in the cosmos. Planetary researchers had previously detected the other five key elements on Enceladus: carbon, hydrogen, nitrogen, oxygen and sulfur (the last of which has been tentatively detected).
