Apr 14, 2014 — Audie Cornish speaks with Fred Espenak, scientist emeritus at NASA Goddard, also known as "Mr. Eclipse," about the lunar eclipse that will happen Monday night.
Mar 23, 2014 — Astrophysicist Neil deGrasse Tyson is everywhere these days. And his current stature is remarkable, in part because he's a black astrophysicist — seemingly as elusive a phenomenon as the Higgs boson.
Mar 6, 2014 — An astrophysicist is using something called the Z machine at Sandia National Lab to recreate the conditions on a white dwarf star — only for a few nanoseconds, but still, enough to study.
Feb 27, 2014 — The astrophysicist says that participating in a "great unfolding of a cosmic story" should make us feel large, not small. This spring, Tyson hosts a TV series called Cosmos: A Space-Time Odyssey.
Feb 14, 2014 — Twenty-six percent in a survey of 2,200 people conducted in 2012 answered that the Sun revolves around the Earth, and fewer than half correctly answered a question about human origins.

Dust off the binoculars: Comet Panstarrs cometh

The days are lengthening, but there's still plenty to see in the night sky. St. Lawrence University astronomer Aileen O'Donoghue joins Todd Moe to talk about the Snow Moon, the meteor that landed in Russia and Comet Panstarrs on the horizon.  Go to full article

Saturn, Jupiter...and comets on the way

Clear nights in the forecast, and the waning crescent Moon make for a great opportunity to bundle up and get outside for some sky-watching.

St. Lawrence University physics professor Aileen O'Donoghue tells Martha Foley that Jupiter and Saturn are high and bright in the sky these days. Aileen's advice: bring good binoculars because there's a good chance you could see Jupiter's famous moons.

And she has news for later this winter, too. There are two comets on our way.  Go to full article

Natural Selections: Cosmic Rays

Martha Foley and Dr. Curt Stager discuss cosmic rays. While many people may think cosmic rays only affect astronauts or satellites--objects in space--computers and other electronic equipment on Earth can be affected too.  Go to full article
