Last week a rare image captured by the Hubble Space Telescope, which can be seen above, was shared by NASA. It's about the asteroid (6478) Gault, a celestial body that attracts attention by the double tail of the comet.
This peculiar asteroid that is in orbit between Mars and Jupiter – at a distance of 345 million kilometers from the Sun – is spinning at a speed as great as self-destruction as the dust blowing from its surface formed two tails.
The larger tail of this "deformed" comet covers a distance of 800 thousand kilometers, while the short one measures a quarter of that measure and does not have much luminosity. The asteroid was discovered in 1988, but it was only in January of this year that it began to transform itself into this peculiar comet.
What was your luck?
For the researchers who studied the case, the theory that most resonates is the YORP effect. This phenomenon (which was only observed twice in history) occurs when sunlight strikes the asteroid unevenly, which causes the surface to heat irregularly, and the star begins to rotate.
What happens then is that the celestial body begins to disintegrate because of the speed that gradually increases. It is possible that the asteroid impacted another body, which could have caused (6478) Gault to eject space dust.
