NASA has a new shocking SECRET about asteroids! Know all about it here

NASA's OSIRIS-REx mission again came up with interesting information about the age of the asteroids. A recent report revealed that scientists learned that surface regeneration of some asteroids happens a lot quicker than on Earth. The results emerged by analyzing rock fractures on the famous asteroid Bennu taken by the OSIRIS-REx spacecraft. The scientists found that heat from the Sun fractured rocks on asteroid Bennu in just 10,000 to 100,000 years. NASA's scientists used a computer model and fracture measurements to calculate this timeframe for thermal fractures.

This huge timeframe might sound slow, but senior scientist Marco Delbo has to say, “We were surprised to learn that the aging and weathering process on asteroids happens so quickly, geologically speaking.” The rapid temperature changes on asteroid Bennu built up the internal stress which resulted in fractures and breaking down rocks. NASA compared it to how a cold glass breaks under hot water. You would be surprised to know that the Sun rises every 4.3 hours on Bennu, and even at the equator, during the daytime, the highest temperature can reach almost 260 Fahrenheit. During the night-time, the lowest temperature can go down to around minus 10 Fahrenheit.

The team of scientists from the OSIRIS-REx mission found cracks in the rocks from the first surveys of the asteroid. These fractures follow the same path, and predominantly align in the northwest-southeast direction. According to Delbo, “a distinct signature that temperature shocks between the day and the night could be the cause.” The same pattern indicates that they were caused by the Sun.

These thermal fractures on Bennu caused by the Sun are quite similar to what we find on Earth or even Mars, a scientist
