Astronomers have discovered that a scorching hot lava planet, believed to be made of diamond, grew a second atmosphere after its star destroyed its first atmosphere.

The discovery was made using the James Webb Space Telescope (JWST).

The planet, called 55 Cancri e or Janssen, is about 8.8 times more massive than Earth, with a diameter about twice that of our planet in the nearby solar system, according to NASA.

The super-Earth planet orbits its star at one-25th the distance between Mercury, our solar system's innermost planet, and the Sun.

55 Cancri e is one of the few rocky planets outside our Solar System that has a significant atmosphere, blanketed in carbon dioxide and carbon monoxide.

This exoplanet is 41 light years away from Earth and orbits its star Copernicus so closely that it has permanent days and nights.

One light year is approximately 6 trillion miles.

“We measured thermal emissions from this rocky planet and the measurements indicate that the planet has a substantial atmosphere,” said Renyu Hu, a researcher at the California Institute of Technology (Caltech), a member of the team behind the discovery. space.com,

“This atmosphere is likely supported by gases escaping from the rocky interior of 55 Cancri e, and we think this is the first measurement of a secondary atmosphere on a rocky exoplanet. It's very exciting,” Reneau said.

The gases released from its magma oceans can play an important role in keeping its atmosphere stable.

In 2016, the Hubble Space Telescope determined that the atmosphere of 55 Cancri e contained hydrogen and helium.

55 Cancri e has a surface temperature of approximately 3,140 °F (1,725 ​​°C/2,000 °K).

The boiling temperature on this planet can reach 4,200 degrees Fahrenheit (2,300 degrees Celsius), which means that life is not possible on it.

“55 Cancri e is so close to the host star that it receives a lot of heat in the form of radiation. That heat keeps the temperature on the planet very high,” Hu said. “At this temperature, everything on the planet is molten. If it is rock, it is molten lava, which helps in the process of releasing gases that support a secondary atmosphere due to the molten surface.”
