Will Mars soon be hidden under a veil of dust? Let's hope not. We explore the current storm and the planet's upcoming close opposition.
If you like sunrises and sunsets, look for the green flash, a phenomenon that happens more often that you think.
The Great Hercules Cluster is on everyone's observing list this summer. But there's lots more to see within a stone's throw of this grand object — like 20 galaxies!
Don't look now — it's already gone! Asteroid 2018 LA screeched into Earth's atmosphere only 7 hours after its discovery to create a Sun-bright spectacle over South Africa and Botswana.
Vesta, the brightest asteroid, puts on one of its best shows ever in June, when it shines enough to see without optical aid.

Jupiter's at opposition this week. Close and bright, it shines like a midnight version of Venus. No matter your scope, the biggest planet is always a crowd-pleaser.
Time travel is one of the best things about astronomy. Check out two websites that give skywatchers a more visceral sense of stellar distances and how constellations change shape across the sweep of time.
In a rare move, a sleepy cataclysmic variable blows its top and suddenly becomes a nova.
Come along for a 7-night tour of some of the Moon's most compelling features visible in small telescopes.

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!
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.
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.
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.
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.
