The Astroholic Explains ·

2023/06/01

When we think of asteroid impacts, we often just picture Chicxulub and the mass extinction of three-quarters of the plant and animal species on Earth, 66 million years ago. But asteroid impacts can be less impactful to life, like the Popigai and Chesapeake impactors - not as big as Chicxulub but still big enough to create craters of over 80 kilometers across, way back around 35 million years ago. Cosmic material could even actually help life bloom.

The Astroholic Explains ·

Measuring the length of a day on Earth is relatively easy thanks to the Sun and stars. But it isn't as easy on some of the other planets, and astronomers had to get pretty clever to actually achieve those measurements. We spoke to Dr Chris Mankovich who was able to measure the length of a day on Saturn via an ingenious method.
