Mercury Is Shrinking Faster Than Scientists Expected
Original: Mercury is shrinking faster than anyone thought
New findings indicate Mercury is contracting more quickly than previous estimates suggested. The smallest planet in the solar system has been cooling and shrinking for billions of years, causing its crust to wrinkle and crack. The updated measurements challenge existing models of how the planet's interior cools, prompting discussion among planetary scientists about what this reveals about Mercury's geological evolution.
Why now: Fresh research suggests Mercury's rate of shrinkage is greater than previously believed, capturing scientific interest
