The universe never ceases to amaze. Research published on Wednesday in the journal Nature gave the news of the incredible discovery of an atmosphere composed of carbon dioxide and carbon monoxide that envelops a super Earth – so defined due to its size – very close to us. The study was possible thanks to the observation of the images captured by the Webb space telescope before and after the passage of the celestial body behind Copernicus, its star.
The exoplanet known as 55 Cancri e is among the few rocky planets outside our solar system to be surrounded by it. Its identity card has already been drawn up: larger than our planet, but smaller than Neptune, it is 41 light years away from us and is covered by oceans of magma from which the gases probably responsible for the stability of the atmosphere escape. The surface can reach boiling temperatures (4,2000 degrees Fahrenheit), which is why it is unlikely to host life.
Geomagnetic solar storm on Earth, here’s when it arrives and what it can cause: scientists are alarmed
But scientists are confident. This discovery is a promising sign that there may be other planets with similar, but much more hospitable, atmospheres. In itself 55 Cancri and represents a special case in science: «It is a rarity, because we can observe the evolutionary phase of a planet», said Renyu Hu, researcher at NASA’s Jet Propulsion Laboratory. Furthermore, studying this star could provide clues to the cooling of both our planet and Mars, which were also born covered by oceans of magma.
