Massive asteroid 3 Juno shines in opposition on Wednesday (Sept. 7) | Space

Wednesday (Sept. 7), will give sky watchers an exciting opportunity to see a giant silver asteroid shining in the sky when the asteroid 3 Juno (Juno) moves opposite the sun. 

The best time to see the asteroid , an inhabitant of the main asteroid belt between Mars and Jupiter, will be around midnight. The asteroid, which takes its name from a Roman goddess, will appear in the constellation Aquarius remaining above the horizon for the majority of the night.

NASA's Spacecraft to be Crashed into Asteroid

NASA controllers will deliberately crash their $330 million spacecraft traveling at more than four miles per second into Dimorphos, an asteroid, in a few weeks, so as to destroy it.

The purpose of this kamikaze science mission is for space engineers to learn how to deflect asteroids in case one is ever discovered on a collision course with Earth.

Asteroid Twice The Size Of Big Ben To Hit Earth's Orbit This Month, Says NASA

When Leonardo Di Caprio and Jennifer Lawrence tried warning the world about an imminent apocalyptic incident, namely an asteroid crashing into earth in last year's acclaimed film Don't Look Up, most people disbelieved them.

In less than two weeks, a gigantic asteroid, which is estimated to be twice the size of Big Ben, the famous clock tower in London, will collide with the Earth's orbit. The enormous space rock, known as 2008 RW, only approaches the planet once every three to four years.

NASA to crash spacecraft into asteroid in an attempt to change its direction - Science News

In a plan straight out of a sci-fi film, NASA will be deliberately crashing the Dart robot spacecraft into an asteroid in order to determine whether the collision can change the latter's course.

In the past, a number of theories have been put forward which involved using an object to deviate any asteroid from its course.

Science Café examines DART — 'How do we move an asteroid?'

At 7:14 a.m. Sept. 26, the DART satellite will slam into the asteroid Dimorphos, which orbits a larger asteroid named Didymos, at the speed of 15,000 mph. 

Picture a vending machine hitting the pyramid of Giza.

The goal is to slightly change the orbital time of Dimorphos as the first test of planetary defense from asteroid collisions. While neither asteroid is any threat to Earth, it is a proof-of-concept mission.

Asteroids brought water on Earth: Study | Tech News

In a new paper published in the journal Nature Astronomy, scientists said the Ryugu samples could give clues to the mystery of how oceans appeared on Earth billions of years ago.

"The delivery of volatiles (that is, organics and water) to the Earth is still a subject of notable debate," it said.

How asteroids bombarded Earth and built the continents - Big Think

Most researchers think that the formation of continents is related to a massive bombardment of asteroids, some of them as large as hundreds of kilometers in diameter, that plagued the entire solar system between 4.1 billion and 3.8 billion years ago.

Based on crater densities on the moon and other solar system bodies, researchers posit that these impacts began to let up between 3.9 billion and 3.5 billion years ago. They did not form continents on the Moon.
