Space News Update - February 13, 2015 In the News Story 1: The View from New Horizons: A Full Day on Pluto-Charon Story 2: A New Way to View Titan: 'Despeckle' It Story 3: Exploded Star Blooms Like a Cosmic Flower Departments The Night Sky ISS Sighting Opportunities Space Calendar NASA-TV Highlights Food for Thought Space Image of the Week The View from New Horizons: A Full Day on Pluto-Charon Click image to view video on YouTube A New Way to View Titan: 'Despeckle' It Exploded Star Blooms Like a Cosmic Flower The Night Sky Friday, February 13 After dusk at this time of year, four carnivore constellations climb upward low in a row across the northeast to southeast. They're all seen in profile, with their noses pointed to the upper right and their feet (if any) to the right: Ursa Major in the northeast with the Big Dipper as its brightest part, Leo in the east, Hydra the Sea Serpent in the southeast (Jupiter shines midway between the heads of Leo and Hydra), and Canis Major in the south. Saturday, February 14 Zenith star. If you're in the world's mid-northern latitudes, bright Capella passes straight overhead, or nearly so, around 7 or 8 p.m. (depending on how far west or east you are in your time zone). It goes exactly through your zenith if you're at latitude 46° north: for example Portland, Oregon; Montreal; central France. And whenever Capella passes highest, Rigel in Orion's foot is always due south. Sunday, February 15 Mid-February is when Orion stands highest in the south after dinnertime. His eastern shoulder, orange-red Betelgeuse, forms the Winter Triangle with brilliant Sirius far below and Procyon to their left. Monday, February 16 The Winter Triangle, or rather one side of it, is also part of a much bigger asterism: the Winter Hexagon. This fills the sky toward the southeast and south these nights. Start with brilliant Sirius at its bottom. Going clockwise from there, march through Procyon, Pollux and Castor, Capella very high, Aldebaran over to Capella's lower right, down to Rigel in Orion's foot, and back to Sirius. The eclipsing variable star Algol will be at its minimum light, magnitude 3.4 instead of its usual 2.1 (in other words a third of its normal brightness) for a couple hours centered on 12:19 a.m. Tuesday morning EST (9:19 p.m. Monday evening PST). Algol takes several additional hours to fade and to rebrighten. Tuesday, February 17 Venus and Mars are now just 2° apart in the west-southwest at dusk. They'll remain at least this close for the next nine days. The shadow of Jupiter's moon Io crosses Jupiter's face from 6:13 to 8:31 p.m. EST, following along sixteen minutes behind less conspicuous Io itself. Around 9:10 p.m. EST, Callisto disappears into occultation behind Jupiter's western limb. Then from 10:35 p.m. to 1:30 a.m. EST Europa's shadow crosses Jupiter, following thirty-five minutes behind Europa itself. And, Jupiter's Great Red Spot comes into view around the planet's celestial eastern edge by midnight EST, to reach the planet's central meridian around 1:47 a.m. EST.
