"Galactic Growth Rate Unveiled by Heat Spots from 12 Billion Years Ago"

Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to draw a temperature map of the dust within one of the oldest spiral galaxies in the universe, revealing two distinct heat sources: a supermassive black hole at the center of the galaxy and the heat generated by newly-formed stars in the surrounding rotating disk. The research provides new insights into how fast the galaxy is growing and a clearer picture of how galaxies and central massive black holes form and grow in the early universe.

Webb Telescope Discovers Water in Atmosphere of Super-Hot Exoplanet

The James Webb Space Telescope has detected water vapor in the atmosphere of WASP-18 b, a super-hot gas giant exoplanet that orbits its star in less than one Earth day. The planet is 10 times more massive than Jupiter and is located some 400 light-years away from Earth. Due to its close proximity to the parent star, temperatures in WASP-18 b's atmosphere reach up to 5,000 degrees Fahrenheit. The Webb measurements enabled scientists to map temperature differences across the planet's surface and found that the most intensely illuminated parts of the planet can be up to 2,000 degrees F hotter than those in the twilight zone.

Webb telescope detects water in atmosphere of super-hot exoplanet.

NASA's James Webb Space Telescope has discovered water vapor in the atmosphere of WASP-18 b, a gas giant exoplanet 10 times more massive than Jupiter. The planet's orbit lasts just 23 hours, and one side always faces the sun while the other is always in darkness. The temperature map of the planet showed a difference of up to 1,000 degrees between the hottest and coolest points, with temperatures changing based on elevation by hundreds of degrees. Despite the high heat, the Webb telescope found multiple small water features in multiple elevations, which could help researchers find similar water vapor in other atmospheres.

Webb Space Telescope Discovers Water on Ultra-Hot Exoplanet

Scientists have used the James Webb Space Telescope to create the first detailed temperature map of exoplanet WASP-18 b and identified water vapor in its extremely hot atmosphere. The planet is an ultra-hot gas giant 10 times more massive than Jupiter, and one orbit around its star takes just 23 hours. The temperature map shows a huge change in temperature from the hottest point facing the star to the terminator, where day and night sides of the tidally-locked planet meet in permanent twilight. The discovery is providing valuable insights into the planet's formation, suggesting it likely emerged from the leftover gas after its star's birth.
