Researchers Detects Carbon Dioxide in Exoplanet Atmosphere

-

UK (CU)_ Researchers at the University of Warwick together with international scientists have confirmed with no doubt the presence of carbon dioxide in a planetary atmosphere beyond our solar system, which consists of the sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

The James Webb Space Telescope which uses infrared astronomy caught an extremely detailed rainbow of near-infrared starlight filtered via an environment of a hot gas-giant planet 700 light-years away.

Researchers revealed 3 new vital findings that included Webb’s first official scientific observation of an exoplanet, the first detailed exoplanet spectrum covering this range of near-infrared colours, and the first indisputable evidence for carbon dioxide in the atmosphere of a planet orbiting a distant star.

These finding demonstrate the telescopes’ ability to note key molecules such as carbon dioxide among many different exoplanets, such as smaller, cooler, rocky planets indicating the composition, formation, and evolution of the planets.

Professor Peter Wheatley of the University of Warwick, Centre for Exoplanets and Habitability, stated that it was inspiring as the initial discovery was found in the environment of WASP-39b, as they found the planet back in 2011 with the UK-led SuperWASP telescopes. He further added that the WASP-39b is a hot planet in close proximity to the parent star which is 900 °C and has a volume more than double that of Jupiter, however the mass was only a quarter of Jupiter making it significantly less dense.

Transiting planets like WASP-39b, whose orbits are viewed from the edge as opposed to the top view, can be an excellent area for researchers to study the planets and as different gases absorb a unique set of colours, researchers can distinguish minor differences in brightness of light transmitted across a spectrum of wavelengths to conclude the specifics of what the atmosphere is made of.

As carbon emissions are a key focus in many nations the impact of carbon dioxide in exoplanets could possibly be an area for future researchers to explore.
