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 percent, which means that more than one exist per star. Despite even the most optimistic statistics, the only life found in the universe is that which is found on Earth....

Methods for Hunting Exoplanets


Posted By on Aug 3, 2016

“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 are difficult to detect using even the most powerful telescopes because they are dim and cool relative to objects such as galaxies and stars, according to Dr. Daniel...

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 July 7, 2016 in a paper published in the journal Science. The system contains a total of three stars. Two stars, one sun-like in character and the other less massive,...

Planet-Forming Disks


Posted By on Jul 7, 2016

The solar system formed when an enormous cloud of gas and dust began to collapse and rotate. As it spun faster and faster, it formed a disk which helped feed into forming the young sun in the center of it all.  From this disk, small particles of dust started sticking together, and continued to grow into objects that were centimeters, then meters, and kilometers in size. Eventually some of these planetary embryos collided, resulting in...

  The planets of our solar system formed out of a swirling disk of gas and dust billions of years ago. The material that accreted to become the Earth lacked water and organic material because it formed at a distance that was too close to the sun for such materials to condense and collect on the new-born planet. Despite Earth’s rocky start, life organized, evolved, and now dominates this small, terrestrial planet orbiting 93...
