On the hunt for new exoplanets
A state-of-the-art instrument called NEID, from the Tohono O’odham word meaning “to see,” has officially started its scientific mission: discovering new planets outside of the solar system.
Giant comet found in outer solar system
The discovery of the comet estimated to 100-200 kilometers across was made by Penn researchers following a comprehensive search of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is the most distant comet ever discovered and possibly the largest seen in modern times.

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.
