Independence Day (U.S.) is the evening when most Americans are watching the sky. While you wait for fireworks, gaze at Jupiter, the Moon, and Saturn! What’s in the Sky the 4th of July As twilight deepens around 9:30 PM on the 4th, the very brightest “star” is the planet Jupiter, to the left of where the Sun set.  At the same time, far to the left of the Moon hover two stars of equal brightness. The orange one is the famous Scorpius star Antares. The other is Saturn.  If you’re in doubt, point... more

This year, the June solstice falls on two different days: Wednesday, the 21st, for those in Eastern Standard Time, and Tuesday, the 20th, for time zones further west!. Enjoy seven cool (or, is it hot?) solstice facts—and see how many you know! If you ask friends what happens on the summer solstice, they’re likely to get it right. It’s the longest day of the year, meaning, the most minutes of sunshine. And the midday Sun is highest up in the sky, or lowest if you live in the Southern Hemisphere... more

When we look up into the sky, we’re looking through dozens of miles of transparent gases, which we breathe from birth to death. So what is the composition of air, exactly? To be more specific, name the top three ingredients that make up air. 1. Ask your friends and, odds are, a few will correctly say nitrogen. It makes up nearly 80% of the air. It doesn’t hurt you and it doesn’t help you, which is sort of like the government of Monaco. 2. Air’s second most common component is oxygen, which is... more

June’s Full Moon is the lowest of the year. This has all sorts of consequences … Technically full on Friday June 9, the Full Moon for June spends the night hovering right next to a bright “star”—the planet Saturn. This is extremely helpful, because unlike Jupiter, say, whose extreme brilliance makes it easy to recognize, Saturn is much harder to identify as a planet unless you know astronomy pretty well. So next Friday, the Full Moon acts as a guide, an usher, so you know where to point a... more

Now that NASA’s Juno spacecraft is orbiting Jupiter and sending us spectacular pictures, especially of its polar regions, we can enjoy a happy coincidence: On this Saturday night, June 3, 2017, Jupiter will form a dramatic tight conjunction with the Moon. This Jupiter-Moon conjunction isn’t one of those pre-dawn, insomniac affairs. The Moon and Jupiter are highest up and closest together at nightfall, and can be seen even in evening twilight. Simply venture out after sunset and find the Moon.... more

Something special happens in the sky Saturday night, May 13.  The Moon will hover next to the planet Saturn.  And they’ll both be aligned with the center of our galaxy.  Cool stuff. And useful.  You don’t really need the Moon to act as an usher to guide you to Jupiter, because Jupiter is so brilliant it attracts attention on its own.  But Saturn is merely a somewhat bright “star” and doesn’t particularly stand out.  So having the Moon float alongside it is very helpful.  Both celestial bodies... more

For the next few days, the sky offers a cool and easy spectacle that requires no astronomy knowledge whatsoever. The dark night’s two brightest objects float together.  Each is fascinating in its own right. A Beautiful Conjunction of Jupiter and the Moon Absolutely everyone can identify the Moon. So it’s easy to spot that bright object next to the Moon—giant Jupiter! And the two join together all night long. They come closest on Sunday, May 7. So at your leisure, just step outside and look... more

We’ve grown up with four seasons. But they don’t always match what we experience. What about dividing our season by the strength of the Sun? Think about it. People who go skiing or snowboarding in mid-December have officially hit the slopes during the autumn. Those who ski in mid-March are doing so during winter.  And yet, those March skiers get sunburned six times faster than those on the slopes in December.  This proves that the Sun is much stronger in mid March.  So is there any way to think... more

This week, the waning gibbous Moon rises an hour later each night, leaving the first part of each night black and ideal for stargazing. The first thing you see is the very brightest “star” in all the heavens—the planet Jupiter. Jupiter came to opposition earlier this month, so it’s at its very brightest of the entire year. Let’s be honest, though. You don’t want to fiddle with charts, and you’d like your astronomy fun and easy. Well, here it is: Just find the brightest star anytime between... more

The Big Dipper is an old friend to most of us. Poetically, it is spring itself, the season of renewal, right now, when the Dipper is best seen. Go out between 9 and 10 p.m., and you’ll see that it hovers so high in the north, it’s almost overhead. Where is the Big Dipper? The Dipper floats forlornly in a dark desolate region of the sky. It’s actually a section of the Great Bear high in the North. This realm lies far from the Milky Way. Hence, the Dipper guides our eyes away from the flat plane... more
