Astronomy topic is ‘Other Worlds’
"Other Worlds" will be the topic of a Frontiers of Astronomy Community Lecture by University of Hawaii astronomer John A. Johnson at 7:30 p.m. Monday at the Institute for Astronomy, 2680 Woodlawn Drive.
Astronomers have identified nearly 300 planets orbiting stars in our galaxy but few known planetary systems resemble Earth's solar system, the IFA said.
Johnson will review knowledge of exoplanets and describe such examples as a hot-Neptune in a two-day orbit around a red dwarf star and a super-Jupiter orbiting a dying giant star.
He earned his doctorate degree last year from the University of California, Berkeley, where he studied with one of the world's foremost discoverers of exoplanets, Prof. Geoffrey Marcy.
