The current estimate for the number of stars with Earth-sized planets orbiting in the habitable zone is about one in four, according to Dr. Daniel Apai Principal Investigator for Project EOS. Other researchers estimates range from as few as 5 percent to more than 100...
A closer look at dust particles Young planet-forming disks contain trillions of tiny microscopic dust particles. Even in the tenuous protoplanetary disk, these particles bump into each other every now and then, sticking together and growing larger and larger with...
“Usually the first thing you find in astronomy are the freaks,” said Dr. Travis Barman, Project EOS co-investigator and associate professor at the University of Arizona. “And the freaks tell you about the exceptions not the rule.” Exoplanets are illusive objects. They...
How do planets form? This is a question that scientists have asked themselves for centuries. Kant (in 1755) and Laplace (in 1796) postulated the nebular hypothesis, which states that the solar system planets formed from a rotating disk of material. Over the years...
A strange and new extrasolar system was discovered by graduate research fellow and Project EOS collaborator Kevin Wagner, principal investigator for Project EOS Daniel Apai, and assistant professor of astronomy at the University of Arizona Kaitlin Kratter, announced...
