2. NASA's Moon Data Sheds Light on Earth’s Asteroid Impact History
In this computer graphic, NASA's Voyager 1 probe, moving toward upper left, nears the edge of the sun's influence, flying through a region of space dominated by a "magnetic highway" that helps mediate the flow of particles into and out of the solar system. The region includes particles from the sun's southern hemisphere that have been forced northward by the pressure of the interstellar wind. Voyager 1 is expected to cross the boundary into interstellar space sometime within the next few years if not sooner. (Credit: NASA)

5. The Night Sky Sky & Telescope Friday, January 18
• Zero-magnitude Capella on high, and equally bright Rigel in Orion's foot, have almost the same right ascension. This means they cross your sky’s meridian at almost exactly the same time: around 9 or 10 p.m. now, depending on how far east or west you live in your time zone. So, whenever Capella passes its very highest, Rigel always marks true south over your landscape, and vice versa.
And tonight, the bright Moon shines between them.
Saturday, January 19
• The Moon shines in Gemini this evening, with Castor and Pollux to its left, Betelgeuse farther to its right, and Procyon down below.
• After dinnertime, Sirius twinkles brightly under Orion in the southeast. Around 8 or 9 p.m., depending on your location, Sirius shines precisely below fiery Betelgeuse in Orion's shoulder. How accurately can you time this event for your location, perhaps using the vertical edge of a building? Of the two, Sirius leads early in the evening; Betelgeuse leads later.
Sunday, January 20
• Full Moon, and total eclipse of the Moon high in a dark sky over the Americas. Partial eclipse begins at 10:34 p.m. EST, total eclipse begins at 11:41 p.m. EST, totality ends at 12:44 a.m. EST, partial eclipse ends at 1:51 a.m. EST. The eclipsed Moon will be in dim Cancer, with the Beehive star cluster about a binocular field-of-view to its east.
See the timetable for your time zone, and things to watch for throughout, in Bob King's Guide to January’s Supermoon Total Lunar Eclipse or the cover story of the January Sky & Telescope. Prefer audio? Here's our special podcast for the eclipseby that voice of Sky & Telescope, Kelly Beatty.
For most of Europe and Africa, the Moon will set around sunrise on the 21st either during totality or during the final partial phases, although westernmost Europe — including the British Isles — and northwestern Africa will be treated to the whole show before the Moon sets and the Sun rises.
Cloudy where you are? Watch the Virtual Telescope Project's livestream of the eclipse.
Monday, January 21
• Venus, which has been approaching Jupiter for many days, appears closest to Jupiter tomorrow morning the 22nd. They'll be about 2½° apart in early dawn. And look for fainter Antares 8° to Jupiter's right.
Think photo opportunity! Attach your camera or phone to a tripod, move around to frame the planet pair with some foreground scenery, and zoom in. Do it before dawn gets too bright!
