After possible signs of life, James Webb Space Telescope to gaze at a planet in another solar system
The Times, scientists have discovered a gas in a planet's atmosphere which could be "only produced by life". The planet is called K2-18b and is located beneath a constellation Leo and on a star K2-18. K2-18 is believed to be roughly half the size of the Sun.
This planet is around 2.6 times bigger than the Earth. The scientists, according to the report, have found dimethyl sulphide (DMS) gas in the planet's atmosphere and it may have been produced by a "phytoplankton in marine environments". The researchers are more than 50 per cent confident that DMS is present in the planet's atmosphere.
Scientists have been yet unable to prove that DMS could be produced in the absence of living beings. But it is not a "conclusive evidence". K2-18b is located 124 light years away from the Earth, making the planet one of its close neighbours.
To get to the planet, it would take around 2,175.44 years in human years for a probe travelling at the speed of the Voyager spacecraft. Voyager spacecraft travels at the speed of 38,000 mph. The telescope, which was launched from the Guiana Space Centre in 2021, conducts infrared astronomy.
It has revealed several wonders since its launch, including the breathtaking pictures of the space it famously sends to NASA. JWST was made at the cost of $10 billion and a 6.5-metre, gold-plated mirror and several complex instruments cooled to temperatures only a few degrees above zero. It has discovered a planet Wasp-107b, 1,300 light years away from Earth.
