Mysterious gaseous & # 39; Forbidden Planet & # 39 ;, discovered that 920 light years from the Earth should not exist so close to its host star, because the atmosphere of 1,832 ° F should have burned down, experts say

  • & # 39; Forbidden & # 39; is the nickname for the planet formally known as NGT & # 39; s-4B
  • Is 3 times as big as the earth, 20 times the mass and found 920 light years away from you
  • The atmosphere is hotter than that of Mercury with temperatures above 1000 ° C
  • Found in a & # 39; Neptunian Desert & # 39 ;, a region around a star where Neptune-size planets did not exist

A gaseous planet about the size of Neptune that was recently discovered is referred to as an astrological anomaly because it should not exist.

NGTS-4B, also known as the & # 39; forbidden planet & # 39; was found in a region that at 920 light years from Earth is referred to as a heavenly & # 39; desert & # 39 ;.

The planet has a surface temperature of 1800 ° C and defies all previous studies by being so close to its star that the atmosphere should have evaporated.

This wasteland around a star caused by immense levels of radiation was supposed to create a strip of space devoid of random gaseous planets.

But & # 39; Forbidden & # 39; is spotted in the middle of this zone that revolves around a star every 1.3 days, 920 light years away from the Earth.

The Neptunian planet, formally known as NGT & # 39; s-4b, was found by University of Warwick telescopes in an international collaboration of astronomers.

It is 20 percent smaller than Neptune, about three times the size of the Earth and has a surface temperature of more than 1000 ° C (1,800 ° F) – hotter than Mercury.

Renamed by researchers as & # 39; The Forbidden Planet & # 39; it revolves around the star in just 1.3 days and is the first exoplanet of its kind found in the Neptunian desert.

It was thought that a large planet as large as NGTs-4b would not be as close to a host star as the immense radiation would cause the gases to evaporate and disappear, leaving only a rocky core.

Researchers from the University of Warwick do not know why the planet defies logic and exists at its current location.

WHAT IS A & # 39; NEPTUNIAN DESERT & # 39 ;?

The Neptunian desert is the region close to the stars where no planets of Neptune have been found.

This area gets a strong appearance from the star, which means that the planets do not retain their gaseous atmosphere when they evaporate and only leave a rocky core.

However, NGTS-4b still has its gas atmosphere.

They speculate that the planet has recently descended to its current position – over the past millions of years or so – or it was previously even larger than its current circumference and the atmosphere is still evaporating.

Experts discovered it when it circled in front of the star and caused the brightness to fall by only 0.2 percent.

Dr. Richard West, from the Physics Department at the University of Warwick, says: & This planet must be hard – it is precisely in the area where we expected that Neptune's planets could not survive.

& # 39; It is really remarkable that we have dimmed a transit planet by less than 0.2 percent through a star – this has never been done before by telescopes on the ground, and it was great to have a year.

& # 39; We are now looking into data to see if we can see more planets in the Neptune desert – perhaps the desert is greener than ever thought. & # 39;

WHAT IS NGTS-4B?

It is a planet with a mass that is twenty times the size of the earth.

It is a large planet with a radius of 20 percent smaller than Neptune – about three times the size of the Earth.

The atmosphere is around 1000 degrees Celsius.

It circles around the star in just 1.3 days.

NGTS-4 is approximately 920 light-years away from the earth.

It exists in a so-called & # 39; Neptunian Desert & # 39; – a region around a star thought the planets of Neptune did not exist.

This unusual behavior led to the nickname & # 39; Prohibited & # 39 ;.

It was detected by Warwick University telescopes as it passed in front of the big star and the brightness dropped by only 0.2 percent.
