China’s Chang’e 7 Will Include a Flag That Will ‘Flap’ on the Moon

China’s Chang’e 7 lunar lander mission will feature a flag fluttering in the vacuum of space.

It’s one of the most often asked questions I get, while showing off the Moon to the public. “Can you see the flag the astronauts left there?” This then leads to a discussion on how far the Moon is, versus the difficulty of seeing a 1.5 by 0.9 meter flag at such a distance. My ‘scope is good, but not that good.

During the U.S. Apollo program, six crewed missions landed on the Moon starting with Apollo 11 in 1969, leaving a like number of flags. Now, China recently announced that one more flag will join the collection in late 2026, when Chang’e 7 heads to the Moon.

Review: Dwarf Lab’s New Dwarf 3 Smartscope

DwarfLab’s new Dwarf 3 smartscope packs a powerful punch in a small unit.

In the past decade, amateur astronomy has witnessed nothing short of a revolution, as smartscopes have come to the fore. In half a century of skywatching, we’ve used just about every iteration of GoTo system available, starting with the now almost prehistoric ‘push-and-point’ AstroMaster units of the 90s. Strange to think, these were the hot new thing for telescopes in the 90s… though you still often had to perform a visual spiral search to actually find the target.

We recently had a chance to put Dwarf Lab’s new Dwarf 3 smartscope through its paces, and were impressed with what we’ve seen thus far. The small telescope even has personality: my wife said it actually looked like Johnny 5 from the 80s movie Short Circuit on start up (!)

The Moon Occults Mars for North America Monday Night, Just Before Opposition 2025

Now is the best time to observe Mars in 2025.

January has an amazing parade of evening planets, well worth braving the cold for. We have brilliant Venus, high to the west after sunset, reaching greatest elongation on January 10^th. Fainter Saturn sits just above Venus as the two meet on January 19^th. Meanwhile, Jupiter dominates the eastern sky, fresh off of opposition in December. But stay awake just a bit longer after dusk, and you can see Mars rising in the east.

As a special treat, observers in most of North America will also see the nearly Full Moon pass in front of Mars Monday night.

Will Comet G3 ATLAS Perform at Perihelion?

Comet C/2024 G3 ATLAS may put on a quick show this month.

What ‘may’ be the best anticipated comet of 2025 is coming right up. Right now, there’s only one comet with real potential to reach naked eye visibility in 2025: Comet C/2024 G3 ATLAS. This comet reaches perihelion at 0.094 Astronomical Units (AU, 8.7 million miles or 14 million kilometers, interior to the orbit of Mercury) from the Sun on January 13^th, and ‘may’ top -1^st magnitude or brighter. At magnitude +4 in late December, Comet G3 ATLAS could become a fine object low in the dawn sky for southern hemisphere observers… if (a big ‘if) it holds together and performs as expected.

The Quadrantid Meteors and More Ring in 2025

This Weekend: Catch the Quadrantids at their annual peak, Earth at perihelion and the Moon blotting out Saturn.

Ready for another amazing year of skywatching? The very first weekend of 2025 offers up a flurry of wintertime astronomy events, eluding a swift meteor shower, a January ‘SuperSun,’ and a lunar planetary pair up at dusk.

Top Astronomy Events for 2025

Catching the best sky watching events for the coming year 2025.

How about that eclipse in 2024? Certainly, the Great North American Eclipse of April 8^th 2024 was one for the ages, instilling the eclipse-chasing bug in many a new skywatching fan. Now, for the bad news: 2025 is a rare, totality free year, featuring only a pair of remote partial solar eclipses. The good news is, there’s lots more in store to see in the sky in 2025, with a pair of fine total lunar eclipses, Mars at its best, and lunar occultations galore. And hey, the Sun is still mighty active, and the cosmos does still owe us another fine comet.

Our Strategy to Catch the 2024 Geminid Meteors

Don’t let the bright Moon deter you from seeing the one of the best meteor showers of the year.

Update: Astronomer Gianluca Masi will carry the Geminid meteors live on December 13th, courtesy of the Virtual Telescope Project.

One of the best meteor showers of 2024 closes out the year this coming weekend. If skies are clear, watch for the Geminid meteors, peaking on the night of Friday into Saturday, December 13-14^th.

Catch Jupiter at Opposition 2024 This Coming Weekend

Now is the time to catch Jupiter at its best.

The King of the Planets rules the winter night skies. Early December gives sky watchers a good reason to brave the cold, as Jupiter shines at its best. Look for the regal planet rising in the east at sunset, while the Sun sets to the west.

Watch the Crescent Moon Occult Spica for North America Early Wednesday Morning

One of the best bright star lunar occultations for 2024 occurs this week, as the Moon covers Spica.

Have you ever seen the Moon blot out a star? If the weather cooperates, early morning viewers across eastern North America have a chance to see a rare spectacle, as the crescent Moon occults (covers) the bright star Spica.

How Scientists Repurposed a Camera on ESA’s Mars Express Mission

A camera aboard the Mars Express orbiter finds a new lease on life.

Sometimes, limitations can lead to innovation. A recent paper highlights how researchers are utilizing the VMC (Visual Monitoring Camera) aboard the European Space Agency’s (ESA) venerable Mars Express orbiter.

The work is a collaboration between the European Space Agency (ESA) and the University of the Basque Country.
