James Webb telescope finds evidence of carbon dioxide on another planet

researchers from NASA and ESA revealed this Thursday, August 25, the opening carbon dioxide in the atmosphere from exoplanet WASP-39b. The discovery has been made James Webb Space Telescopethe most powerful telescope made by mankind and having equipment capable of determining the composition of the Earth’s atmosphere. planets light years from earth.

Carbon dioxide detected in WASP-39b

O OSA-39bwhich is located at a distance of 700 light years from Earth and is located in the constellation Virgo. exoplanet type Jupiter a hot, gas giant that is very close to its star – it orbits its star in just four days. It was discovered in 2011, and studies of its characteristics have already confirmed the presence of hot water molecules in its atmosphere, the chemical composition of which should be unbalanced.

The discovery of carbon dioxide – CO2 – on a planet outside the solar system is surprising for several reasons: first, it shows the ability James Webb in determining the chemical composition of distant atmospheres with incredible accuracy – something that has never been done before – and even on small rocky planets. This is possible thanks to NIRSpets, an acronym for Near Infrared Spectrography Instrument. When Telescopehe identified carbon dioxide using wavelengths from 4.1 to 4.6 microns, which is much more accurate than Hubble and Spitzer.

Second, the composition of the atmosphere is the basis for studying how the planet formed. Role JWST Now we have to accumulate a “portfolio” of the atmosphere so that researchers can conduct more detailed studies of planetary formations.

Thirdly, this discovery confirms the words of Bill Nelson, administrator NASAthe biggest role of the agency, on the day of the first images JWST were revealed. Nelson said James Webb will bring us closer to the discovery of life or a habitable planet in the universe. This new discovery shows Telescope can answer our big question: are we alone in the universe?

James Webb must study another curious planet

Scientists from the University of Montreal in Canada announced the discovery exoplanet which can be completely covered with water. baptized from TOI-1452 bThe “ocean planet” – or true “water planet” – is located 100 light years from Earth, which is a relatively small distance in the astronomical world.

The researchers responsible for the study have already indicated that they will try to schedule a period of use JWST study the composition atmosphere TOI-1452 b. They want to use the tools James Webb to determine if the planet has an atmosphere that is thought to contain hydrogen and helium.
