The 10-million-year-old young star HD 166191 that NASA was able to find via the Spitzer Space Telescope.
Since 2015, NASA has been observing this young star. Astronomers found a cloud covering the star HD 166191.
NASA astronomers are still observing where the thick cloud came from.

Clouds Around Young Stars HD 166191
NASA is an American astronomical agency. They have contributed greatly to the discovery of outer space.
NASA’s space agency has always successfully studied many objects in the solar system and the universe. One of the objects that NASA has produced for a long time is HD 166191.
HD 166191 is a young star whose existence was identified in November 2013. Astronomers call it a young star because it is only about 10 to 15 million years old.
NASA is observing this young star with their advanced space telescope called the Spitzer Space Telescope.
With the help of the Infrared Telescope Facility (IRTF) at the top of Mauna Kea, Hawaii, NASA classified HD 166191 into the Stellar classification and has an active temperature of around 6,170 to 50,000 Kelvin.
In 2015, NASA discovered a cloud of debris that blocked the light from the young star. Of course the cloud has a very large size.
Astronomers finally re-examined what was the cause of the cloud was created. They predict that the cloud was formed as a result of a mixture of two large objects the size of an asteroid.

The Forerunner of a New Planet
The Spitzer telescope had previously found evidence of a collision around the young star HD 166191. For this reason, NASA began looking for other evidence using the Spitzer telescope.
In a period of four years, namely 2015 to 2019, NASA has managed to collect more than 100 observations.
When objects are very small and too far away to be observed through a telescope, collisions around stars form dust infrared which is very helpful.
Spitzer detects light infrared as dust that is included from the debris of protoplanetary collisions.
In 2018, the HD 166191 system got brighter and produced more wreckage. At that moment Spitzer detected a cloud of debris already covering the star.
Astronomers estimate the size of the cloud to be about three times the size of the star itself. If you look at the size of the cloud, the possibility of colliding objects is also very large.
The object is at least the same size as a dwarf planet, such as Vesta in our solar system which is an asteroid measuring 330 miles or 530 kilometers.
In 2019, the clouds covering HD 166191 are no longer visible covering the star.

However, the star system detected was creating more dust than Spitzer observed before the cloud.
Astronomers and NASA researchers have revealed that the collision has the potential to create new planets around the young star HD 166191. However, astronomers have not been able to determine the exact time of formation. (R10/HR-Online)
