CNN —An ultrahot exoplanet that zips around its host star every 19 hours is the shiniest exoplanet ever discovered. The scorching world, dubbed planet LTT9779b, has reflective metallic clouds made of silicates and metals like titanium. An artist's illustration shows an exoplanet, called LTT9779b, orbiting its much larger host star. The side of the exoplanet that faces its host star likely reaches 3,632 degrees Fahrenheit (2,000 degrees Celsius). And LTT9779b is so piping hot that it shouldn’t have any clouds, even those made of metal or glass.

CNN —A Jupiter-like planet located 520 light-years from Earth may be an unlikely survivor after its host star had a temper tantrum. The gas planet is known as 8 UMi b and was named Halla after its initial discovery by Korean astronomers in 2015. The exoplanet orbits a giant star larger than our sun named Baekdu, located in the Ursa Minor, or “Little Bear,” constellation. Halla orbits Baekdu at a distance about half that between the Earth and the sun at 0.46 astronomical units, or 42,759,659 miles (68,815,020 kilometers). While our solar system only has one star, many stars across the universe exist in binary pairs.

☆ 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.

In our solar system, Earth and Venus are volcanically active, as are some of Jupiter's moons. Planets beyond our solar system are called exoplanets. Here, water from the nightside glacier can melt and possibly form liquid surface water. In addition, there is likely volcanism all around the planet, even under the ice on the nightside and possibly under the water near the terminator," Benneke said. The planet is located in the Milky Way about 86 light-years away from our solar system in the direction of the constellation Crater.

Fomalhaut, a star just 25 light-years away, is so dazzlingly bright that it blots out the faint light of other stars around it. Stargazers have been enraptured by its secrets for thousands of years. Now, with the help of the James Webb Space Telescope, astronomers have documented evidence that Fomalhaut is a dynamic star wreathed in cosmic chaos. The powerful observatory’s infrared vision is letting astronomers better understand Fomalhaut’s features, including a mysterious ring unlike anything found in our solar system. “It’s the first time we’ve seen such structures in an evolved system.”The findings could contribute to the solution to an existential puzzle: How weird, or ordinary, is our solar system?

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.

☆ Repeating radio signal leads astronomers to an Earth-size exoplanet

CNN —Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. The signal suggests that the Earth-size planet may have a magnetic field and perhaps even an atmosphere. The researchers believe the radio signal was created by interactions between the planet’s magnetic field and the star. How strong radio waves occurIn order for the radio waves to be detectable on Earth, they must be very strong, the researchers said. “This research shows not only that this particular rocky exoplanet likely has a magnetic field but provides a promising method to find more.”

CNN —Google’s much-hyped new AI chatbot tool Bard, which has yet to be released to the public, is already being called out for an inaccurate response it produced in a demo this week. Bard’s blunder highlights the challenge for Google as it races to integrate the same AI technology that underpins Microsoft-backed ChatGPT into its core search engine. In trying to keep pace with what some think could be a radical change spurred by conversational AI in how people search online, Google now risks upending its search engine’s reputation for surfacing reliable information. Like ChatGPT, Bard is built on a large language model, which is trained on vast troves of data online in order to generate compelling responses to user prompts. The executive said AI technology would pave the way for the “next frontier of our information products.”

☆ How exoplanet hunters find alien worlds hundreds of light-years away and figure out if they have water

In the journal Nature Astronomy, astronomers announced that the two exoplanets — Kepler-138 c and Kepler-138 d — could be made up of mostly water. NASA AmesSince the first worlds outside our solar system were discovered in 1992, astronomers have searched for other planets orbiting sun-like stars. Astronomers have already captured direct evidence of 5,241 planets beyond our solar system, according to NASA's Exoplanet Archive. Water worlds beyond our solar system could be abundant in the universeWorlds rich in liquid water might not be as rare as astronomers previously thought, Piaulet said. But by discovering and studying new worlds, astronomers can hone in on what makes a world habitable beyond a sample size of one — Earth.

There's a new heavy hitter in the hunt for planets beyond our solar system. NASA’s James Webb Space Telescope — the next-generation observatory that has already beamed back some of the clearest and most stunning views of the universe — was used for the first time to confirm the existence of an exoplanet, scientists announced Wednesday. The exoplanet confirmation marks an important milestone for the $10 billion Webb telescope, which launched into space in December 2021 and began science operations less than a year ago. “These first observational results from an Earth-size, rocky planet open the door to many future possibilities for studying rocky planet atmospheres with Webb,” Mark Clampin, director of the astrophysics division at NASA headquarters in Washington, D.C., said in a statement. “Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is only just getting started.”

The first full-color image released from the next-generation James Webb Space Telescope is the sharpest infrared image of the distant universe ever produced, according to NASA.
