NASA’s James Webb Space Telescope has detected water vapor in a “planet-forming” area of a distant star, the agency announced Monday.
detected the super-hot water vapor in an inner ring of gas and dust around a distant star known as PDS 70 which shares a remarkable amount of similarities with the sun.
PDS 70 is roughly three-quarters the mass of the sun, and at 5.4 million years old is relatively close in age to the sun, which is roughly 4.6 billion years old. The water vapor, detected using the James Webb Space Telescope’s mid-infrared instrument, was also found at a distance from the star similar to the Earth’s distance from the sun , signaling the area could be conducive to life.that knowledge about PDS 70 provides crucial information about how planets in the sun’s solar system likely formed, and confirms that water is present in a region where “planets similar to Earth may be assembling.
—supermassive stars up to 10 billion times brighter than the sun that had been thought to be purely theoretical.

JWST Sees Newly Forming Planets Swimming in WaterOne big question about Earth’s formation is, where did all the water come from? New data from the James Webb Space Telescope (JWST) shows newly forming planets in a system 370 light-years away are surrounded by water vapor in their orbits. Although astronomers have detected water vapor in protoplanetary disks before, this is the first … Continue reading 'JWST Sees Newly Forming Planets Swimming in Water'
