In astronomy, the rule was if you can’t see it, it’s not real. Tell that to the astronomers who discovered dark energy or dark matter … or, more recently, Planet 9. Find out how we know what we know about the latest cosmic discoveries – even if we can’t see them. Plus, did dark matter do in the dinosaurs? And the winner of the 2015 Nobel Prize in physics explains why neutrinos may hold clues to the origin of the universe.
The dramatic fall reentry of a piece of space debris has served as a dress rehearsal for researchers who observe small asteroid entries and impacts. The object, tagged as WT1190F, reentered Earth’s atmosphere near the coast of Sri Lanka on Nov. 13, 2015.
It’s long been thought that most stars would be similar to the Sun – sporting only relatively weak magnetism. But an international group of astronomers, including SETI scientist Daniel Huber, has discovered that strong magnetic fields are actually common for stars.
The fall meeting of the AGU – the American Geophysical Union – is being held from December 14 though 18 in San Francisco. Among its 24,000 attendees are many SETI Institute scientists, giving talks and presenting posters.
Applications are now CLOSED for the Summer 2016 Research Experience for Undergraduates Program. Life in the Universe – Astronomy and Planetary Science at the SETI Institute. Work on projects spanning the field of astrobiology from microbiology to planetary geology to observational astronomy. Thanks to everyone to who applied.
Using the Gemini Planet Imager (GPI) as well as the Hubble Space Telescope, Kalas and his colleagues examined a star known as HD 106906 ... the remarkable thing about this stellar system is the discovery that a planet in its outer regions (16 times as far from the star as Pluto is from the Sun) may have been expelled from its birthplace.
