NASA telescopes track 170-foot asteroid charging towards Earth for a close approach

[ad_1] We've heard the tale of an asteroid crashing on Earth nearly 65 million years ago and wiping out the dinosaurs since our childhood. But did you know that it is backed up by a hypothesis? According to the Alvarez hypothesis, this extinction was caused by a massive asteroid that crashed on Earth. Scientists have also discovered the origin of the asteroid. It would've originated between the orbit of Mars and Jupiter. The asteroid terraformed the planet and is likely the reason that started the extinction of dinosaurs. Scientists have even found the impact crater of the asteroid in Chicxulub, near the Yucatan Peninsula in Mexico. Can a similar asteroid strike Earth today? Although experts say an asteroid could again impact the Earth, it is a 250-million-year cycle and is very likely ...

NASA lab hopes to find life’s building blocks in asteroid sample

[ad_1] Eager scientists and a gleaming lab awaits.A sample from the asteroid Bennu, which could be key to understanding the formation of the solar system and our own planet, is set to be analyzed at NASA's Johnson Space Center in Houston after it reaches Earth in late September. The precious cargo is currently aboard OSIRIS-REx, a US space probe launched in 2016 to Bennu, which orbits the Sun at an average distance of about 105 million miles (168 million kilometers). Long white sleeves hang from the huge metal and glass box in which the sample will be handled.Scientists will separate pieces of the rock and dust for study now, while carefully storing away the rest for future generations equipped with better technology -- a practice first started during the Apollo missions to the Moon."We...

Can a dangerous asteroid strike Earth and destroy humanity? Know here

[ad_1] How dangerous are asteroids for Earth? Can a dangerous asteroid strike Earth and destroy it? Get an answer to these questions here. Can asteroids be dangerous for Earth? Tens of millions of years ago, a single asteroid collided with the planet, which is said to be the reason behind the extinction of dinosaurs. Though the collision was destructive, our planet survived! Does this mean that Earth cannot be destroyed by an asteroid even though living things on it may go extinct? That cannot be said! Due to the gravitational pull, Earth tends to attract certain objects like asteroids and meteors towards it leading to crashes. However, there is no potential harm caused by these objects until and unless they are large such as...
