May 17, 2013 — Generations of physicists have claimed that time is an illusion. But not all agree. In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists—and he says time is key to understanding the evolution of the universe.
May 10, 2013 — The SETI (Search for Extraterrestrial Intelligence) Institute's Jill Tarter has spent decades searching for the signals that would tell us we aren't alone in the cosmos. Tarter discusses the hunt, and what the presence of intelligent life elsewhere might tell us about our own future on Earth.
May 10, 2013 — Saul Perlmutter shared the 2011 Nobel Prize in physics for his discovery that the universe was expanding at an accelerating rate. Perlmutter explains how supernovae and other astronomical artifacts are used to measure the expansion rate, and explains what physicists are learning about "dark energy" — the mysterious entity thought to be driving the acceleration.
May 7, 2013 — Turns out our solar system — with its medium sized sun, its four small rocky planets, its four big gassy ones farther out — isn't like the others. We are unusual. Very unusual. Says one prominent astronomer, we are "a bit of a freak."
Apr 26, 2013 — The James Webb Space Telescope will succeed Hubble in 2018, boasting modern computers and a mirror with seven times the viewing area. Bob Hellekson, ATK Program Manager for the telescope, discusses the telescope's newly constructed wings, designed to support the telescope's folding mirror, and astrophysicist Stacy Palen talks about what the telescope may reveal about the cosmos.

Natural Selections: the Pleaides
Paul Smiths, NY, Jun 21, 2012 — The Greeks called them "The Seven Sisters," but a look at the Subaru logo shows the Japanese saw them differently. This familiar star cluster constellation actually contains thousands of stars when viewed through a telescope, as well as brown dwarf proto-stars and dust nebulae and newly-forming solar systems. Martha Foley and Curt Stager look at the night sky. Go to full article
Earthlings watch the Venus Transit
Canton, NY, Jun 06, 2012 — Yesterday evening Venus made its last journey across the face of the sun, as seen from Earth, until the year 2117. People of all ages covered the southeast corner of the St. Lawrence University practice fields to get their look at earth's closest neighboring planet, peering through one of the big telescopes or a pair of safe solar glasses.
