为什么一天24小时长:天体物理学家梦吗al Why Earth's Day Was a Constant 19.5 Hours for Over a Billion Years

Astrophysicists have revealed how the slow and steady lengthening of Earth's day caused by the tidal pull of the moon was halted for over a billion years. They show that from approximately two billion years ago until 600 million years ago, an ...

Life After Death: Astronomers Find a Planet That Shouldn't Exist

The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...

Molecular Filament Shielded Young Solar System from Supernova

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially destroyed the nascent Solar System. New calculations shows that a filament of molecular gas, which is ...

Earth Was Created Much Faster Than We Thought: This Makes the Chance of Finding Other Habitable Planets in the Universe More Likely

Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that water and other essential ingredients for life ...
