A ‘Tail’ of Two Comets

A ‘Tail’ of Two Comets

Two comets that will safely fly past Earth later this month may have more in common than their intriguingly similar orbits. They may be twins of a sort. Comet P/2016 BA14 was discovered on Jan. 22, 2016, by the University of Hawaii’s PanSTARRS telescope on Haleakala, on the island of Maui. It was initially thought […]

Our Solar System May have Once Harbored Super-Earths

Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths–planets larger than Earth but smaller than Neptune. If so, those planets are long gone–broken up and fallen into the sun billions of years ago largely due to a great inward-and-then-outward journey that Jupiter […]
