Lightning Strikes Can Look an Awful Lot Like Meteors

Lightning Strikes Can Look an Awful Lot Like Meteors But when we look back through the geological record, we’re separated from the event by tens of thousands, if not millions of years.This puts a lot of strain on the rock and creates a special type of crystal known as shock quartz.

A huge asteroid named Florence is zipping by Earth today, but don't freak out A huge asteroid with an old-fashioned name is passing by Earth today, but don't worry.The asteroid known as Florence — named for Florence Nightingale, of course — is about 2.

Astronomers Will Photograph Asteroid Probe During Earth Flyby

Astronomers Will Photograph Asteroid Probe During Earth Flyby NASA’s OSIRIS-REx probe is currently on its way to an asteroid to do some very cool science, but it has to make a quick stop by Earth first.As the probe executes a flyby of its home planet in the next few weeks, astronomers around the world will be watching the sky to get one last look at OSIRIS-REx before it heads off to the asteroid Bennu.

Ancient Meteorite Impact Produced Highest Natural Temperature Ever On Earth

Ancient Meteorite Impact Produced Highest Natural Temperature Ever On Earth This 17-mile (28-kilometer) depression contains Mistastin Lake, which is quite obviously an impact crater when seen from above.There’s an arcuate central island in the lake, which is the central uplift of the original impact crater, and the lake itself is roughly circular.

Scientists Propose Studying Hundreds of Asteroids with Nanoprobe Fleet

Scientists Propose Studying Hundreds of Asteroids with Nanoprobe Fleet Scientists have been able to examine a few asteroids close up, and the OSIRIS-REx mission will soon grab a sample from one asteroid and return it to Earth.However, it would take ages to get a full overview of the wide variety of asteroids by visiting one at a time.

Hubble Discovers a New Type of Asteroid

Hubble Discovers a New Type of Asteroid There’s usually a stark difference between asteroids and comets, but so-called “active asteroids” blur the line.This object is stuck in the asteroid belt between Mars and Jupiter, but its orbit occasionally leaves it in the same general neighborhood as Earth.

The Oldest Rocks on Earth Could Contain Signs of Life

The Oldest Rocks on Earth Could Contain Signs of Life A team of Japanese scientists studying the oldest rocks on Earth has found new evidence to support the existence of life during the “Late Heavy Bombardment” period.These rocks are as old as 4 billion years, only half a billion younger than the Earth itself.
