Aug 16, 2014 — For those willing to travel a bit, venture out and allow your eyes to adjust to the darkness, many places still offer the chance to enjoy the soul-lifting sight of a starry night sky.
Aug 10, 2014 — The second of three so-called "supermoons" this year can be seen under clear skies Sunday night, but some argue the term is a bit of a stretch.
Aug 4, 2014 — The European Space Agency's Rosetta Mission has taken the long way to reach Comet 67/P. Later this week, it will finally arrive.
Jun 23, 2014 — On Titan, summer is almost three years away. But in a dark, placid ocean of natural gas, scientists have spotted something that could be the first inkling of springtime.
May 20, 2014 — Fifty years ago today, two astronomers in New Jersey accidentally discovered the Big Bang's afterglow. The roaring space static their hilltop antenna detected came from the birth of the universe.

Clear skies, longer nights offer great star-gazing

The days are getting shorter, by about three minutes every 24 hours now, and that's welcome news for Aileen O'Donoghue. It means more time for looking at the night sky.

O'Donoghue teaches physics, including astronomy, at St. Lawrence University, and stopped by the NCPR studios this morning to deliver an update on the current highlights in what she calls the wilderness above us.

She tells Martha Foley about Venus (hanging in the west at sundown), Saturn (nearby, but fainter and MUCH farther away), and the waning crescent, and Jupiter (both in the morning sky). And then there's the new crescent, coming Monday.  Go to full article

Catch a glimpse of falling stars: the Perseid meteor shower

St. Lawrence University astronomer Aileen O'Donoghue turns our attention to the wonders of the night sky, including the peak week of the Perseid meteor shower.

Also, look for Venus near the horizon at sunset, with Saturn to its left. The moon will be in Scorpio tonight, and in the morning, look for Jupiter next to Orion in Gemini.  Go to full article

Tracking the planets this spring

We're gaining about three minutes of daylight every day now, and the winter constellations such as Orion are starting to slip below the horizon. Jupiter will be the brightest object in the sky other than the moon. Look in the southwest sky in the early evening near the Pleiades. This weekend, the crescent moon will be paired up with Jupiter in the early evening.

Look for Saturn in the morning sky in the southwest. In May we will start to see Venus in the western sky close to Jupiter. Martha Foley talks with St. Lawrence University astronomer Aileen O'Donoghue.  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.
