☆ Unlocking the clues of a metal world
  + stars: | 2023-10-06 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +5 min
CNN —For the first time, a NASA mission is setting off on a distant journey to visit a metal world in our solar system. This illustration depicts how scientists envision the Psyche asteroid. Over time, Psyche likely collided with other rocky objects, losing its outer crust and mantle until only its metal core remained. “We have never seen the surface of a metal world up close. “If you brought back as much metal as likely exists in Psyche, then the metals would no longer be rare and the price would plummet,” Metzger said.

☆ Earth-size exoplanet may be covered in volcanoes
  + stars: | 2023-05-17 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +6 min
Instead, the exoplanet, called LP 791-18 d, is likely covered in volcanoes and may experience eruptions with the same frequency as Jupiter’s moon Io, the most volcanically active place in our solar system, according to researchers. LP 791-18 d is located about 90 light-years from Earth in the Crater constellation, where it orbits a small red dwarf star. And astronomers believe the massive planet LP 971-18 c might be contributing to the newly detected exoplanet’s possible volcanism. As the two objects orbit their star, LP 971-18 c and the newfound exoplanet LP 791-18 d closely pass each other, allowing the gravitational pull of the larger planet LP 971-18 c to tug on planet d and reshape its orbit. The discovery of LP 971-18 d points to the importance of data collected by space telescopes.
☆ Webb telescope detects mysterious water vapor in a nearby star system
  + stars: | 2023-05-02 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +5 min
CNN —The James Webb Space Telescope has detected water vapor around a rocky exoplanet that orbits a star located 26 light-years away from Earth. The presence of water vapor could suggest that GJ 486 b somehow has an atmosphere, despite its heat and proximity to the star. “Water vapor in an atmosphere on a hot rocky planet would represent a major breakthrough for exoplanet science. The results from the Webb data analysis pointed to water vapor being present around GJ 486 b. Future observations of the planet using different instruments on the Webb telescope could reveal additional details about the source of the water vapor.
☆ James Webb telescope: New data on WASP-39b is a 'game changer,' scientists say
  + stars: | 2022-11-24 | by ( Taylor Nicioli | ) edition.cnn.com   time to read: +4 min
CNN —The James Webb Space Telescope has captured a detailed molecular and chemical portrait of a faraway planet’s skies, scoring another first for the exoplanet science community. This “hot Saturn” was one of the first exoplanets that the Webb telescope examined when it first began its regular science operations. Bocaprins’ close proximity to its host star makes it an ideal subject for studying such star-planet connections. The planet is eight times closer to its host star than Mercury is to our sun. … We are already getting very exciting results,” Nestor Espinoza, an astronomer at the Space Telescope Science Institute, told CNN.
☆ Jupiter's aurora triggered a planet-wide heat wave, a map animation reveals, solving a mystery that's puzzled scientists

An astronomer's map of a heat wave on Jupiter helped solve the planet's "energy crisis" mystery. Solar plasma triggered an aurora at Jupiter's north pole, which sent a heat wave spilling down the planet. He's still studying the features of the heat wave, which he presented at the Europlanet Science Congress in September. O'Donoghue published his team's first research linking Jupiter's aurora to planet-wide heating in 2021. They think the aurora storm and resulting heat wave came from a surge of plasma from the sun.
