Scientists Discover New Class Of Exoplanet
Scientists have discovered a new class of exoplanet that is half rock and half water, making them the most water-rich planets ever discovered.
Scientists Find Evidence Of Ancient Ocean On Mars
Scientists have just recently uncovered evidence of a vast, ancient ocean that existed on Mars around 3.5-billion years ago.
What Are Supernovae?
A supernova is a stellar explosion representing the final stage of a star’s life. Supernova generally occur in stars 8 to 15 times the mass of the sun.
How Fast Did The Moon Form?
A new model predicts that it took the moon only a few hours to form after the Earth was impacted by another planet 4.5-billion years ago.
Tree Rings Reveal Evidence Of Radiation Storms
Over the last 10,000 years, the Earth has experienced multiple bombardments of radiation called Miyake Events. The exact cause of these events is a mystery.
Why Do The Gas Giants Spin So Fast?
The gas giants spin significantly faster than the rocky planets, likely due to the amount of angular momentum involved in their formation.
