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 — 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 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 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.

Great Lakes Radio Consortium: Women Astronomers
Feb 20, 2002 — Astronomy historically has been dominated by men, but women have left their mark over the years. A new planetarium show is trying to shine a little light on advances in astronomy that were made by women. The Great Lakes Radio Consortium's Tamar Charney reports. Go to full article
Light Pollution: Taking Back the Night Sky
Feb 13, 2002 — The invention of electric lights at the end of the 19th Century ended the ancient tyranny of darkness over our lives. Turning on the lights at night has allowed us to make every hour count. But while nighttime lighting has given us unprecedented security and uncountable opportunities, we may be reaching the point where we have too much of a good thing. The Great Lakes Radio Consortium's Ed Janus reports on two people involved in an international effort to turn the lights down a little and take back the night. Go to full article
