Using the James Webb Space Telescope, asthronic detection of a planet that is more cold in every world that is colder – astonishing detection in our universe.
Exoplanet, WD 1856 + 534 B, first stained In 2020, it is twice older than our solar system. The world is the size of the Jupiter, but a total of -125 ° Fahrenheit (-87 ° Celsius) is about six times more massive and very chili. This makes it the coldest explanet observed directly with its spreadlight. Exoplanet and his heat emission is the team’s review Currently the landlord Archive on a pre-prepared server.
Exoplanet brings an imaginary fragrance of a white dwarf and a dead star. In fact, this is what the object is possible; Typically, the stars are so bright that the planets are drowning a very boring gloom. The star of WD 1856 B is so dark that Exoplanet himself appeared on the webb. Astronomer Mary Anne Limbach, astronomer in the University of Michigan, helped to investigate.
It is controversial, because this planet is hung. WD 1856 b Orbits, compared to mercury, only 0.02 astronomical unit, more astronomical unit sun compared to mercury. “WD 1856 + 534 B Now the White Dwarf Zone,” An area where the planets are explained in paper “,” On paper “, a region that includes the orbits on paper – white dwarfs present a planetary evidence. “
The team puts the work of the cold world in 1856 at the beginning of the rain order. Just in the back Epsilon nowLast year, a planet learned by Webb, then at the time of 35 degrees Fahrenheit (2 degrees), made the coldest images of the coldest view of our solar system. It’s enough to say, WD 1856 B is colder.
The findings also solve the stretching personality crisis. So far, WD could have been 1856 b a low mass brown. However, weak temperature and revised mass calculations (more than 5.9 yupiter mass), this is an official part of thousands of scientists in the last few decades.
Research is also the main proof of the concept for a reminder that JWST’s cold, mature planets can still hide the burning nucleus orbit of dead stars.
