“Venus analog” tested for suitability for life KXan 36 Daily News

The Webb Space Telescope Exploration Mission took infrared measurements of the putative atmosphere of the exoplanet TRAPPIST-1 c. It’s been dubbed the “Venus Twin,” but a new study has found that this world probably doesn’t look as much like Venus as previously thought.

The study was published in the journal Nature, and Phys.org talks about it briefly. Using infrared instruments aboard the Webb Space Telescope, scientists have successfully measured the thermal radiation of the exoplanet TRAPPIST-1 c. This world is located in the TRAPPIST-1 star system, which has long puzzled astronomers.

This system is only 40 light years from Earth. TRAPPIST-1 c is one of seven rocky, rocky planets orbiting an ultracool red dwarf. The planets are similar in size and mass to the rocky inner planets in our solar system. Thus, the intriguing star system, until recently, was considered by many to be one of the leading contenders for the discovery of life.

But it has not yet been established whether these planets have an atmosphere similar to the atmosphere of the planets of the solar system. The researchers tried to find the answer to this question. Daytime temperatures on the surface of TRAPPIST-1 c hover around 107 degrees Celsius. It’s too hot for life as we know it. On the other hand, this planet turned out to be the coldest of all those planets whose thermal radiation could be measured by infrared instruments.

The results of the analysis, the researchers say, will disappoint those who expected the TRAPPIST-1 system to be a true analogue of our solar system.

“TRAPPIST-1 is interesting because it is essentially a twin of Venus: it is about the same size as Venus, and it receives the same amount of radiation from its host star that Venus receives from the Sun,” says co-author Laura Kreidberg. “We think it might have a thick carbon dioxide atmosphere, like Venus.”

However, the measurement data showed that TRAPPIST-1 c is unlikely to have a thick carbon dioxide atmosphere. This suggests that the planet itself, and possibly the entire star system as a whole, could have formed with very little water. In short, the result of the study suggests that the planet’s atmosphere, if it exists at all, is extremely thin. And it’s unlikely to be capable of supporting life as we know it.

The scientists note that these initial measurements do not provide conclusive information about the nature of TRAPPIST-1 c, but help narrow down likely scenarios. “Our results are consistent with whether the planet is a bare rocky world with no atmosphere, or a planet with a very thin carbon dioxide atmosphere (thinner than on Earth or even Mars) with no clouds,” said the author. Principal Sebastian Zieba. . In his opinion, if the colder and warmer planets in the TRAPPIST-1 system formed under similar conditions, then they, too, at an early stage of their formation, should have had very little water and other necessary components to make them fit for life. life. .
