What attracts the attention of experts is the enormous amount of dust clouds, which are larger than expected from a small object.

An international team of researchers recently published in The Journal of Astronomy Study In it they claim to have discovered a strange cosmic object Emitting large dust clouds In space with varying intensity.

Observations were made from data analysis from the Transiting Exoplanet Survey Satellite (Des, Its abbreviation in English), a modern device launched in 2018 with the aim of locating planets beyond our solar system. So far, TESS has identified 172 exoplanets, and 4,703 applicants are awaiting approval.

Astronomers have noted that an object named TIC 400799224, consisting of two stars orbiting each other, is usually featured. Fluctuation in its brightness, Whether it is a large asteroid or even a small planet orbiting one of the stars and emitting dust clouds that obscure light from TESS view.

This process occurs approximately every 19 days, but the duration and intensity of the glow will fade Will vary a lot.

The team believes that the culprit for the decrease in brightness is not often the asteroid or planet, but rather the occasional dust clouds emitted by that object.

However, the large amount of dust clouds that strike the attention of astronomers is much larger than expected from a small object such as the TIC 400799224.

“The nature of one’s own body in orbit Is mysterious because the amount of dust emitted is high; If it were produced by the decay of an asteroid like Ceres in our solar system, it would only survive about 8,000 years before disappearing. Points out The Harvard-Smithsonian Center for Astrophysics reports that the institute is owned by astronomer Karen Collins, one of the authors of the study.

“However, surprisingly, in the six years that this material has been observed, the time interval has been drastic and The dust-emitting material is apparently intact“Adds text.

This is a mystery, and for the time being there is no answer, but researchers plan to constantly monitor the object and combine historical observations from that area of ​​space to determine how brightness varies over the decades.
