Reference Don't miss these celestial treats this Halloween!

To see the Crab Nebula for yourself, you'll have to wait until around midnight local daylight time, after it has sufficiently risen high enough above the east-northeast horizon.

While some are hoping for a bright "Halloween comet," astronomers say the speeding cosmic snowball has likely already broken apart.

The Orionid meteor shower 2024 reaches its peak in the pre-dawn hours on Monday, Oct. 21, but this year a bright moon could make it difficult to see these shooting stars.

The largest full moon of 2024 rises this week when the Hunter's Supermoon takes to the sky on Wednesday (Oct. 16), becoming officially full the next morning.

There's been talk of another spectacular comet putting on a show in our sky after Tsuchinshan-ATLAS. Unfortunately, however, it doesn't look like the newcomer will deliver.

Scientists are excited to begin capturing Comet Tsuchinshan-ATLAS as the object is expected to soon be very bright in the night sky.

These Venus-moon conjunctions occur on roughly a monthly schedule.

Comet Tsuchinshan-ATLAS will have a close encounter with the sun today (Sept. 27) here's how to make the most of comet viewing opportunities this weekend and beyond.

There will come a time 1.21 billion years from now when the phenomenon of a total eclipse of the sun will become an impossibility.

The autumnal equinox brings fall to the Northern Hemisphere today as the sun passes directly over the equator at noon. But are day and night actually equal length today?

During the morning hours of Sunday, Sept. 22, skywatchers will be able to watch a waning gibbous moon cross in front of probably the most popular of all the star clusters in the sky: the Pleiades.

The final hurdle for Tsuchinshan-ATLAS to surmount will come on the afternoon of Sept. 27, when it arrives at perihelion — the closest point in its orbit to the sun.

The upcoming Full Harvest Moon on Sept. 17 will feature a partial lunar eclipse. Here's what to expect and how to see it.

Thousands of skywatchers will gather for a view of the ringed sun from perhaps one of the most isolated and remote spots on the face of the Earth: the legendary and mystical Easter Island.

Although officially known as the celestial archer, the zodiacal constellation of Sagittarius is far better recognized as a teapot. Here's how to see it this season.

We provide the latest details on this comet, which might (or might not!) blossom into a bright naked-eye object in our October evening skies.

Riding high in the northeast sky as darkness descends is a striking zigzag row of five stars marking the Queen of Ethiopia, Cassiopeia.

This months' full moon falls on Aug. 19 and it will be the only full moon of August 2024. So how can we call it a "Blue Moon?"

On Aug. 14, Mars and Jupiter will appear to be the closest they've been in over two years.

The 2024 Perseid meteor shower should reach its peak during the overnight hours of Aug. 11 into early Aug. 12, when there is almost no moon.

The annual Perseid meteor shower should put on a nice show this weekend — but a spectacular Perseid display appears to be in the cards four years from now.

Of all of the monthly meetings between the moon and Venus this year, this one is by far the closest.

As we make the transition from July into August, Venus has finally begun climbing up out of the sunset glow in earnest and is now about to reclaim its role as the brilliant Evening Star.
