The Moon is Older Than Scientists Thought

   01 Aug 01:00:01  |  Universe Today

The most comprehensive and widely-held theory of how the Moon formed is called the ‘giant impact hypothesis.’ That hypothesis shows that about 150 million years after the Solar System formed, a roughly Mars-sized planet named Theia collided with Earth.

What Did the Early Milky Way Look Like

   28 Jul 01:00:01  |  Universe Today

In the very early days of our Universe, just over 13 billion years ago, there was very little structure. There were stars, and they were forming at a rapid rate, kicking off what’s known as the Stelliferous Era. But the enormous, majestic galaxies that we see today, including our Milky Way galaxy, hadn’t formed yet. …

Fossilized Clams Had Evidence of a Meteorite Impact Inside Them

   27 Jul 01:00:01  |  Universe Today

When an extraterrestrial object slams into the Earth, it sends molten rock high into the atmosphere. That debris cools and re-crystallizes and falls back down to Earth. Tiny glass beads that form in this process are called microtektites, and researchers in Florida have found microtektites inside fossilized clams. This story starts over 10 years ago …
