Hellish 'one-of-a-kind' alien planet is rocky 'Super Earth' with its own atmosphere and deadly oceans of molten magma

SCIENTISTS have discovered that a fiery hell planet may have its own atmosphere and is covered in a sea of ​​molten magma.

55 Cancer was discovered in 2004 and has remained a mystery to scientists who have been studying it for two decades.

Also known as Janssen, the planet is located about 40 light-years away from Earth and is one of five known planets orbiting the Sun-like star 55 Cancri, according to NASA.

The exoplanet is classified as a “super-Earth” as it is twice the diameter of Earth and sits between the size of our home planet and Neptune.

It orbits so closely to its star, about 45 of the distance between Mercury and the Sun, that the entire surface of the planet is a bubbling ocean of hot magma with temperatures hot enough to melt iron, according to Live Science.

Researchers have pondered what kind of rocks could live on a planet with such hot temperatures.

“The planet is so hot that some of the molten rock should evaporate,” explained Renyu Hu from NASA's Jet Propulsion Laboratory, according to NASA.

So they still believed, even with the extreme heat, 55 Cancri e was bare except for vaporized rock, rich in elements like silicon, iron, aluminum, and calcium.

NASA also observed that because it orbits so closely to its star, the planet may be tidally locked, meaning it cannot spin, so one side of the planet is always blanketed with light while the other is in never-ending darkness.

Questions regarding the planet included its orbit cycle, its density, but mostly whether or not it had an atmosphere.

NEW INFORMATION

The James Webb Space Telescope has shared groundbreaking evidence pointing to the boiling hot planet having a unique atmosphere.

Scientists used multiple techniques to suggest that it exists.

They used JWST's Near-Infrared Camera and Mid-Infrared Instrument to measure 4-to-12-micron infrared light coming from the planet.

The technology isn't able to take a picture of the planet, but it has the ability to measure small changes in light as it orbits 55 Cancri.

Researchers used secondary eclipse spectroscopy to determine whether an atmosphere was present.

They subtracted the star's brightness during the secondary eclipse, as it passes behind the star, from the planet and star's brightness when they are side by side.

What is an exoplanet?

Here's what you need to know…

  • An exoplanet is a planet that is located outside of our solar system and is orbiting its own star, like how Earth orbits the Sun.
  • They are very hard to see with telescopes because they are often hidden by the brightness of their star
  • Nasa sent the Kepler space telescope into orbit to find Earth-sized exoplanets that might support life
  • Over 5,500 exoplanets have been discovered so far, and more missions to find even more exoplanets are planned.
  • A good way to spot an exoplanet is to look for wobbly stars, because a disruption to starlight can indicate that a planet is orbiting it and therefore blocking out light on occasion.
  • Exoplanets are very common in the universe, and the more we find that look like Earth, the closer we get to knowing whether we're alone out there.

By doing so, scientists were able to find infrared light coming from the day side of the planet.

Another way they suggested there was an atmosphere was from the planet's thermal emission in the form of inferred light.

If the planet is how they believe with dark molten rock and floating vaporized rock, the side of the planet that faces the star should be about 4,000 degrees Fahrenheit.

“Instead, the MIRI data showed a relatively low temperature of about 2,800 degrees Fahrenheit [~1540 degrees Celsius],” said Hu, per NASA.

“This is a very strong indication that energy is being distributed from the dayside to the nightside, most likely by a volatile-rich atmosphere.”

The new readings also recorded the planet's infrared light during a secondary eclipse which allowed scientists to do calculations.[/caption]

They also observed using the NIRCam data that there is a drop in the spectrum between 4 and 5 microns suggesting that there is carbon monoxide or carbon dioxide which absorbs the wavelengths of light, according to NASA.

A planet with no atmosphere or only one of vaporized rock wouldn't have that feature.

The scientists also considered the molten lava on the planet as they discussed the possible atmosphere.

They believe that magma is bubbling from the interior because any outside gas would be long gone.

Although the planet is uninhabitable, researchers think it could be a tool to study interactions between atmospheres, surfaces, and the inner workings of rocky planets.

“Ultimately, we want to understand what conditions make it possible for a rocky planet to sustain a gas-rich atmosphere: a key ingredient for a habitable planet,” said Hu, according to NASA.
