Scientists Observe Carbon Dioxide on Planets Outside the Solar System for the First Time

Contains carbon dioxide For the first time we have been identified on any planet outside the solar system. The James Web Space Telescope in four observes the gas directly ExoplanetsAll HR 8799 systems belong to the Earth’s 130 light-year. CO detection₂ These four giant planets are similarly strong that strong Jupiter And SaturnThrough the slow formation of the hard core. Were in search Published In the recent issue of the astronomical journal.

“We have identified these powerful structures of carbon dioxide and show that these planets have enough fractions of heavy ingredients such as carbon, oxygen and iron,” said William Balmer, an astronomer at the University of Johns Hopkins, and William Balmer, an astronomer at the University of Johns Hopkins, said in a statement. NasalThe “They are given what we know about the orbital stars, it likely indicates that they were formed by original synthesis, which we see directly for the planets, this is an exciting conclusion.”

HR 8799 is a system that was born 30 million years ago and it is younger than our solar system, which exists for 4.6 billion years. Still hot from their violent structure, the planets of HR 8799 emit a lot of infrared light. It provides valuable data on how scientists compare them or with it with their structure Brown dwarfThe word given to large aerial planets that fail to develop into stars.

“With this kind of research, our hope is that our burden is compared to our own solar system, life and other exoplanetary systems, so that we can make our existence relevant,” Balmer said. “We want to take pictures of other solar system and see how they are different or different from us. From there we try to understand how strange our solar system is, or how normal it is.”

Carbon dioxide has become an essential ingredient for the development of life in the world, it has turned it as the main goal of the search for life elsewhere.

Plus, because the reason₂ In the deep cold of the space, the synthesis of small ice particles, its presence can shed light on the planet’s formation. Jupiter and Saturn are believed to have been formed through a process where a small ice particles were assembled for the formation of a solid core, which we know today absorb gas to increase gas giants.

“We have other lines of evidence that these four planets are on the formation of these four planets,” said Laurent Pwio, a astronomer at the Space Telescope Science Institute and a colleague of the paper. “How common can we figure out directly to the long-time planets?

James unlocks the possibility of the web space telescope

The James Web Space Telescope should also be given its flowers, as it has shown that it is capable of doing more than the atmospheric composition of the exoplanets from the sterlight measure; In fact, it has demonstrated its power Direct analysis The chemical combination of the atmosphere away like them.

Generally, JWST can barely detect an exoplanet because it crosses the front of its host star, due to great distances that separate us. On this occasion, however, the JWST’s coronagraphs – otherwise, directly observed by the acts that blocked the starlight to reveal the hidden worlds.

Balmer said, “When you look at the sky, your thumb is like keeping in front of the sun.” This setting, similar to a solar eclipse, allows the team to look for infrared light at the wavelength from the planet, which reveals specific gas and other atmospheric details.

“These giant planets have very important effects,” said Balmer. “If these huge planets act like bowling balls through our solar system, they can disrupt, protect or, in one sense, both the planets like us.
