Discovery of a giant Earth with a dense atmosphere – what experts say – Newsbomb – News

the Super-Earth, known as 55 Cancri eIt is one of the few rocky planets outside our solar system With great atmosphereWrapped in a “blanket” of carbon dioxide and carbon monoxide.

The exact amounts are unclear. Earth’s atmosphere consists of a mixture of nitrogen, oxygen, and other gases.

“This is perhaps the strongest evidence yet that this planet has an atmosphere,” he said. Ian Crosfield, an astronomer at the University of Kansas Who studies exoplanets. Boiling temperatures on this planet can reach 2300 degrees Celsius, i.e. planet It is unlikely to host life.

Overall this discovery It is the best evidence yet of a rocky planet with an extra-molar atmosphereFrom our solar system!

Researchers use NASA’s James Webb Space Telescope They may have detected atmospheric gases around 55 Cancri e, a hot, rocky exoplanet located 41 light-years from Earth.

the Renew is from NASA’s Gas Propulsion Laboratory in Pasadena, California He is lead author of the study published today in the journal Nature. “Webb is expanding the boundaries of exoplanet characterization to include rocky planets,” Hu said. “It really allows for that A new kind of science.

What do scientists say?

However, scientists say this discovery is a hopeful sign that there may be other rocky planets with thick atmospheres that may be more habitable.

This planet is 41 light-years away from the solar system, its mass is eight times that of Earth, and its surface is covered with oceans of magma.

The research was published in the journal Nature.
