A tale of two pulsars' tails: Plumes offer geometry lessons to astronomers



University Park PA (SPX) Jan 19, 2017
Like cosmic lighthouses sweeping the universe with bursts of energy, pulsars have fascinated and baffled astronomers since they were first discovered 50 years ago. In two studies, international teams of astronomers suggest that recent images from NASA's Chandra X-ray Observatory of two pulsars - Geminga and B0355+54 - may help shine a light on the distinctive emission signatures of pulsars, as well as their often perplexing geometry. Pulsars are a type of neutron star that are born in supernova ex ... read more

Lowell Observatory to renovate Pluto discovery telescope
The instrument at Lowell Observatory used by Clyde Tombaugh to discover Pluto will soon undergo renovation. The year-long project, set to begin on January 12, will include restoration of both the historic telescope and the wooden dome that houses it. While the telescope will be removed from the dome during this work, the dome will be open from time to time for public tours as work allows. ... more

The moon is older than scientists thought
A UCLA-led research team reports that the moon is at least 4.51 billion years old, or 40 million to 140 million years older than scientists previously thought. The findings - based on an analysis of minerals from the moon called zircons that were brought back to Earth by the Apollo 14 mission in 1971 - are published Jan. 11 in the journal Science Advances. The moon's age has been a hotly d ... more

New research by Harvard astronomers shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of o ... more
