NASA continues to surprise the world more and more and on this occasion, it revealed that the James Webb telescope detected atmospheric gases surrounding the rocky and fiery exoplanet 55 Cancri e.

The new discovery of the space agency’s super visual tool is the best evidence they have of an atmosphere of a rocky body very far from our solar system.

“Researchers using @NASAWebb may have found atmospheric gases surrounding a rocky, though likely molten, exoplanet 41 light-years away – the best evidence yet for a rocky planet atmosphere outside our solar system,” NASA published in X.

55 Cancri e is also known as Janssen and is one of the five planets that orbit a star similar to our sun, although with the slight difference that it is located in the constellation of Cancer.

Its diameter is almost double that of the Earth and its density is slightly greater.

55 Cancri e is classified as a ‘super Earth’, that is, larger than our own planet but smaller than Neptune.

It is so close to its sun that it is quite likely that its surface is molten, to the point of being a bubbling ocean of magma.

A long road since its discovery in 2011

It has been 13 years since exoplanet 55 Cancri e was discovered, a date since which astronomers have dedicated themselves to considering a question: does it have an atmosphere?

Diana Dragomir, an exoplanet researcher at the University of New Mexico and co-author of a paper published in Naturedeclared that she was happy with this discovery after several years without a response.

“It’s been really frustrating that none of the observations we’ve been receiving have solidly resolved these mysteries. I’m delighted we’re finally getting some answers!” Dragomir expressed.

The atmospheres of gas giant planets are to some extent easier to detect by NASA’s Hubble Space Telescope, unlike the atmospheres of rocky planets, which are thinner and denser, making them more difficult to discover. .
