Stare up at the Milky Way band on a dark night and you'll see missing pieces from clouds of foreground dust that absorb the light of distant stars. There are other mottled "milky ways" just like ours, millions of light-years away.
The sky's been bursting with exploding stars this season. Plus there's a new storm on Saturn. What's a skywatcher to do? Haul out the scope!
The two Dog Stars stand vertically aligned around the end of twilight. Look southwest. Brilliant Sirius in Canis Major is below; Procyon in Canis Minor is high above.
We lift the Lion's paw to find a bright, red variable star, a germinating planetary nebula, galaxies rarely visited, and a diversity of doubles.
After nightfall, Orion is still well up in the southwest in his spring orientation: striding down to the right, with his belt horizontal. Shining above the belt is bright orange Betelgeuse. Down below the belt is bright white Rigel.
This month's astronomy podcast guides you around the nighttime sky during April, giving you easy-to-follow help for finding bright planets and key stars after the Sun goes down.
Southern Hemisphere objects like Omega Centauri and the Magellanic Clouds make Northern Hemisphere observers envious. Today, we turn the tables and find out what those living in negative latitudes would love to see up north.
China's premier space station, Tiangong 1, has a one-way ticket into the Earth's atmosphere later this month. See it before it's no more.
The first-quarter Moon shines high above Orion on the evening of March 24, 2018, in the feet of Gemini below Castor and Pollux.
Stars are time machines that can transport us into the past or future. They can also illuminate our own personal journeys, as Arcturus did for me one night.
Watch the low in the east-northeast for the rise of the "Spring Star," Arcturus. Find the Big Dipper high in the northeast and follow the curve of its handle far around and down to see where Arcturus will be.
Open clusters present a mystery. Some fall apart in a few hundred million years, others hang around for billions. Join me as we visit both the youngest and oldest star clusters in the Milky Way.
Friday, March 9 • Just after twilight fades away this week, bright Sirius stands due south on the meridian. Sirius is the bottom star of the equilateral Winter Triangle. The Triangle's other two stars are orange Betelgeuse (Orion's shoulder) to Sirius's upper right, and Procyon to Sirius's upper left. • In early dawn Saturday…
How and when to see Alpha Centauri, the Southern Cross, Omega Centauri, and many other celestial sights on a trip south of the equator.
Mercury and much brighter Venus glow shyly side by side very low in the west in twilight early in the week, then they slowly pull farther apart.
With winter's chill fading away, this is a great time to gaze up into the stars — and to be ready for an evening appearance by fleet-footed Mercury. This month's astronomy podcast guides you around the nighttime sky.
With this week's full Moon, the dazzling crater Tycho will be in full regalia. Time to catch some rays!
Friday, February 23 • First-quarter Moon (exact at 3:09 a.m. on this date EST). For North America this evening, the Moon shines left or upper left of Aldebaran, and farther upper right of Orion, as shown here.
