A meteor that exploded in the sky over Chelyabinsk, Russia in 2013 could have also been somehow involved in the giant impact that formed the Moon. This tantalizing finding comes thanks to a new way of dating collisions between rocks in space, based on microscopic analysis of minerals within meteorites. Although further investigation is warranted, … Read more
China’s Yutu-2 mission has made another fascinating discovery on the far side of the Moon. Glistening amid the dry, gray dust, the rover’s panoramic camera picked out two small intact spheres of translucent glass. Such spherules can record information about the Moon’s history, including the composition of its mantle and impact events. Yutu-2 was … Read more
Nothing on Earth can live without water. The origin of water on Earth, therefore, is the origin of life in the Solar System (and the Universe) as we know it. Figuring out where and how our world obtained its water might be key to finding life on other worlds, but the truth is we don’t … Read more
There are few bigger questions than how life first got started on Earth, but trying to put in the detective work almost 4 billion years after the event is understandably hard going for scientists. Now it looks as though we might have found another clue. New research focuses specifically on peptides, smaller versions of … Read more
A pair of asteroids orbiting the Sun formed less than 300 years ago, a new study has revealed. This makes them the youngest pair of asteroids ever discovered in the Solar System, by a factor of 10. The discovery could tell us more about how asteroids crumble, while raising some intriguing new questions. “It’s … Read more
We don’t know how life emerged on Earth, but one thing is certain: life as we know it on our planet wouldn’t exist without the water that wraps around the surface, runs in rivulets, and falls from the sky. Our planet is the only one known to have life, and the only one on … Read more
The moon formed a hundred million years after the creation of the solar system. This has left scientists wondering what was the cause of our planet’s satellite to birth if it didn’t come from the events that formation of the planets. Here are just three of the most plausible explanations. Giant impact hypothesis The prevailing … Read more
The moon’s crust might have formed from an unevenly layered “slush” of magma that once covered the entire body, a new study reports. It’s the latest turn of the wheel on scientists’ picture of how the moon and its features formed, a picture that’s been continually changing ever since Apollo astronauts brought moon rocks back … Read more
Before Earth and the other planets in our Solar System existed, the Sun may have been surrounded by giant rings of dust similar to Saturn’s, according to a new study. Those rings of dust may have prevented Earth from growing into a “super-Earth” – a type of planet that is about twice the size of Earth and … Read more
Scientists have observed a stunning demonstration of classic physics giving way to quantum behavior, manipulating a fluid of ultra-cold sodium atoms into a distinct tornado-like formation. Particles behave differently on the quantum level, in part because at this point their interactions with each other hold more power over them than the energy from their movement. … Read more
