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.

Let the moon be your guide

So much to see in the sky these nights, including a view into the center of our galaxy. That's where radio astronomers can see a bunch of stars orbiting the big black hole at its heart.

St. Lawrence University physics professor and astronomer Aileen O'Donoghue gives Martha Foley the low down on the summer sky. Planets: Mars, Saturn and Venus; constellations: Scorpius and Sagittarius; and stars: Antares, Arcturus, Zubenelgenubi and Zubeneschamali, among others.

She says the Moon is our guide for lots of the highlights, once the evening light fades. It lingers long these days. Enjoy while you can; we're just past the latest sunset of the year and we should notice a real "gain" in darkness in the coming weeks.  Go to full article

In the summer night sky: Solstice, aphelion, planets and skywatching events

The Summer Solstice is this Saturday, and there's plenty to see in the summer night sky. St. Lawrence University astronomer Dr. Aileen O'Donoghue joins Todd Moe for a chat about the start of summer and a great season to view various planets in the pre-dawn and dusk skies.  Go to full article
Half the planets are visible right now--the back row (Jupiter and Saturn) and the front (Mars and Mercury). Aileen says five are visible, actually, if you just look down.

Planets, planets, planets: who's up and where

St. Lawrence University physicist Aileen O'Donoghue says the planets are the big news of the night sky just now. Between Mercury (just up in the northwest), Jupiter in the west, Saturn in the east, and Mars in the middle, there are four visible these nights. And Earth (just look down, she says) makes five.

This, plus how we're losing dark as spring gives over to summer next month, and much more from Aileen's monthly stop in our studios this morning.  Go to full article
