Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon composition seen to date in a protoplanetary disk, including the first extrasolar detection of ethane and a relatively low abundance of oxygen-bearing species. By including previous similar detections, this finding confirms a trend of disks around very low-mass stars to be chemically distinct from those around more massive stars like the Sun, influencing the atmospheres of planets forming there.

NASA's James Webb Space Telescope has scored another first, detecting evidence of water in a planet-forming disc circling another star where at least two terrestrial-class proto-planets seem to be forming.

Astronomers have discovered water vapor in the planet-forming region of a star, which could help shed light on where Earth's water came from.

Despite closeness to the star, the water vapours have likely survived due to dust shielding which protects it from the star's ultraviolet radiation. | World News
