The coldest planet he sees at all is the rotation of a stars

Astronomers who use the James Web telescope for space directly discovered the faint glow of the most cold of any world that has been directly appeared – a stunning discovery that reveals the harsh conditions of some worlds in our world.

The external planets, WD 1856+534 B, were, I was first monitored In 2020, he is weakened by our solar system. The world is about the size of Jupiter, but about six times more large and cooler, recorded at moderate temperature only -125 degrees Fahrenheit (-87 ° C). This makes it colder than a planet outside the surveillance planets directly through the emitted light. The team’s research describes the external planets and their thermal emissions It is currently hosted On Preprint Arxiv server.

The outer planets revolve around a white dwarf, the ghost of the dead star. In fact, this is what made the detection of the object possible; The stars are usually so bright that they drown in the glow of the dull planets. WD star 1856 B is so diminished that the external planets themselves were visible to a web look. Astronomy Marie Ann Limbach of the Department of Astronomy at the University of Michigan contributed to the study.

What can be said is the strangest place where this planet is hanging on. WD 1856 B revolves around 0.02 astronomical units of the white dwarf star – Klauser from Mercury to Shamsa. “WD 1856+534 B is now the first planet outside the proven sound planets in the forbidden area of ​​the white dwarf,” a region that the planets could have been overwhelmed during the giant stage of the giant star, “the team explained in the paper, adding that” its presence provides direct evidence that planetary migration to documentary degrees – including in return – safely. “

The team’s work also puts WD 1856 at the top of the cold in the cold world. Behind it only Epsilon Indi ABPlanet was studied by Web only last year, which made it at the time the coldest photography planet outside our solar system at a temperature of 35 degrees Fahrenheit (2 ° C). Suffice it to say, WD 1856 B is cooler.

The results also settle the outstanding identity crisis. To date, WD 1856 B could have been a low -mass brown dwarf. But at a faded temperature and estimates of the revised mass (not more than 5.9 blocs of Jupiter), it is an official part of the catalogs of thousands of external planets that have collected over the past few decades.

The research is also a major evidence of the concept of JWST’s ability to study the ripe cold planets-and remind that even the worlds that revolve around the burnt core of dead stars are still glowing, no matter how faded.
