Moon and Gemini stars next few nights

On October 21, 22 and 23, you’ll find the moon traveling in front of the constellation Gemini the Twins, to the south of its bright stars Castor and Pollux.

The Orionids radiate from a point near the upraised Club of the constellation Orion the Hunter.  The bright star near the radiant point is Betelgeuse.

Orionid meteor shower peak tonight!

Orionid meteors probably most prolific in the few hours before dawn Friday. The moon will prove troublesome this year.

Many people use the M- or W-shaped constellation Cassiopeia to find the Andromeda Galaxy.  See how the star Schedar points to the galaxy?  Click here to expand image.

Tonight, find the Andromeda galaxy

The Andromeda galaxy is the closest big galaxy to our Milky Way. Here are a couple of different ways to find it. Just be sure your sky is dark!

Small Magellanic Cloud orbits our galaxy

Small Magellanic Cloud resembles a luminous cloud, but it’s really a dwarf galaxy, orbiting our Milky Way. Here’s how to see it, from Earth’s Southern Hemisphere.

Jan Haines Ricco in Delton, Michigan caught this waning gibbous moon on the night of October 17, 2016.

Where’s the moon? Waning gibbous

The Northern Hemisphere’s Hunter’s Moon – and the 1st of 3 supermoons in 2016 – has come and gone. The moon is now waning and rising later at night.


Moon occults Aldebaran October 18-19

From much of the US, Mexico, Caribbean, Central America and southeast Canada, Aldebaran will disappear behind the moon’s lit side and reappear on its dark side.

See a daytime moon after sunrise

The moon is up during the day half the time, as it orbits Earth once a month. The next few mornings are a good time to notice a daytime moon.


What’s special about a full moon?

The October 15 full moon is the Northern Hemisphere’s Hunter’s Moon and a supermoon. But all full moons are special. Here’s why.

Keep watching Hunter’s Moon October 16

If you live at northerly latitudes, the waning moon tonight will rise sooner than you might expect. If you live in the S. Hemisphere, it’ll rise later!

2016 has a super Hunter’s Moon

The Northern Hemisphere’s full Hunter’s Moon for 2016 falls the nights of October 15 and 16. Will it be bigger, brighter, more colorful?

Happy super Hunter Moon!

The full moon on October 15-16 is the Northern Hemisphere’s Hunter’s Moon. It also ushers in the 1st of 3 full-moon supermoons in 2016.


Waxing toward full Hunter’s Moon

You’ll see a nearly full moon tonight. The full Hunter’s Moon – a supermoon – will come on the night of October 15.

Schedar lies at the Queen’s heart

Cassiopeia the Queen is an easy-to-find constellation from northerly latitudes. It has the shape of an M or W. Schedar is the Queen’s brightest star.

Double Cluster in Perseus: 2 star clusters

Charles Messier didn’t include the Double Cluster in his famous catalog. That’s probably because there’s nothing like this magnificent cluster anywhere in the sky.


What bright star flashes red and green?

A bright star twinkling with red and green flashes, low in the northeastern sky on October evenings, is probably Capella.

Minor lunar standstill and Hunter’s Moon

The moon’s appearance in our sky follows a cycle. The cycle of minor lunar standstills diminishes some Hunter’s Moon characteristics in 2016.


Moon and Neptune on October 12

Don’t expect to see Neptune in the moon’s glare on October 12, 2016. But the moon can help you imagine this planet’s location in the starry sky.

Waxing gibbous moon about to set on the night of August 12-13. The golden color stems from the fact that - when we see a moon low in the sky - we're seeing it through a greater-than-usual amount of atmosphere. Photo by Peter Lowenstein.

Where’s the moon? Waxing gibbous

You might spot a waxing gibbous moon against a blue afternoon sky in the next few days. It’s waxing toward the Northern Hemisphere’s full Hunter’s Moon.
