Astronomers noticed changes in the asteroid dimorph, which has been monitored since September. In the fall, NASA rammed it during a historical experiment to change the orbits of space bodies capable of encountering the ground, foreign media write.
According to the researchers, two days after the ram, the Hubble telescope noticed that the asteroid had “grown” with a tail of more than 10,000 kilometers. On new images of dimorph, the second “comet -like tail” from dust and debris.
Scientists have not yet been able to explain why this happened. This may be due to the influence of the solar wind on the material thrown from the surface of the asteroid or with the rotation of the cosmic body.
