The scientific team shows that the brown dwarf system, whose origins are still poorly understood, can have very low mass and very far, but is still closely related. the bizarre pairing of two brown dwarfs.
Astronomers will conclude that brown dwarfs separated by billions of kilometers will be destroyed as they move through galaxies over time, the researchers said.
The Backyard Worlds project allows anyone with a computer and an internet connection to search for images taken with NASA’s WASE (Wide Field Infrared Survey Explorer) and help astronomers identify new worlds outside our solar system. . If an object is close enough to Earth, it looks “cracked” when comparing several pictures taken in the same place in the sky for several years.

The goal of Backyard Worlds volunteers, numbering more than 50,000, is to mark the moving objects they see in this digital flip book for further study by the science team.
So far, volunteers have seen more than 4 million flip books.
In June 2018, civil scientists saw an unusual pair when looking at backyard drawings: an object that looked faint but quickly removed the mark from a new brown dwarf, and other light objects that moved nearby and at the same speed.
The Backyard Worlds science team was surprised and immediately enthusiastic about this rare observation of space.
Brown dwarfs, sometimes called “failed stars”, are common in the Milky Way. They don’t have enough mass to maintain stable fusion, but they are hot enough to shine bright in the spectrum of infrared light.
While brown stars and dwarfs appear in pairs or in larger groups, it is not common to find pairs with small overall masses and very large distances from each other.
In December 2018, Backyard Worlds science team members used the FIRE Baade Magellan telescope equipped with FIRE in Chile to confirm that the weaker source was actually a member of one of the coldest brown dwarf classes: T8.
Lighter objects are also confirmed as low temperature objects: L1.
They also learned that L1 had previously been observed with the European Space Agency’s Gaia telescope and was only 78 light-years from the Sun.
The researchers used the distance calculated by Gaia to accurately measure the brightness of each source and obtain mass estimates. They found that the T8 object was about 34 times bigger than Jupiter and L1 about 72 times bigger than Jupiter. now the citizen Scientists have uncovered a bizarre pairing of two brown dwarfs.
They are separated by 341 astronomical units (1 astronomical unit is the estimated distance between the Sun and Earth, about 93 million miles).
This system is estimated to run for billions of years.
Although there are a number of young couples competing for this mass and separation, no old system is known to be able to compete with it, which raises the question: how and why these space pairs survive, the researchers said.
Researchers say: We are still looking for clues about how the shape of a brown dwarf is formed, and this system is a provocative example of what might happen at the end of the Milky Way’s survival.
