Connecting a star’s chemical composition and planet formation

Along with developing a new statistical method for studying exoplanets, researchers from Penn found that the majority of stars in their dataset are similar to the sun, implying that many stars in the Milky Way could host their own Earthlike planets.

The largest comet ever discovered in modern times is zooming toward the sun

Gary Bernstein of the School of Arts & Sciences spoke about the giant comet he and Ph.D. candidate Pedro Bernardinelli discovered. "We have the privilege of having discovered perhaps the largest comet ever seen—or at least larger than any well-studied one—and caught it early enough for people to watch it evolve as it approaches and warms up," Bernstein said.
