September offers a number of fascinating lunar occultation events worldwide.
Chances are, there’s one near you this month. The Moon is certainly busy in September, as its passage covers up (occults) multiple celestial objects worldwide. If skies are clear, you may just get a chance to see one of these events listed below, as the Moon blocks out a star, planet or star cluster.

The first of a set of groundbreaking Cluster satellites is set for a controlled reentry next week.
The European Space Agency is paving the way in controlled reentry technology. ESA recently announced that plans to terminate the first of four Cluster satellites is about to come to fruition in early September, with the reentry of Salsa.

Comet Tsuchinshan-ATLAS may be one to watch for at dawn late next month.
If predictions and prognostications hold true, a decent comet could grace dawn skies in late September into early October. We’re talking about Comet C/2023 A3 Tsuchinshan-ATLAS, discovered early last year. Early signs suggest it could be the best comet of 2024… if it survives until perihelion.

Well-placed observers have a rare opportunity to see an interplanetary spacecraft early next week.
If skies are clear, dedicated observers and imagers have a shot early next week at seeing a spacecraft headed to Jupiter.
The Mission is JUICE, the European Space Agency’s Jupiter Icy Moons Explorer. Launched atop an Ariane-5 rocket from Kourou Space Center in French Guiana on April 14th, 2023, JUICE is due to arrive at Jupiter in 2031. But first, the spacecraft will perform several planetary flybys to pick up speed, hurdling it towards the outer solar system.

We may be already seeing the makings of next solar cycle, peeking out through the current one.
It’s been a wild ride. Thus far, Solar Cycle Number 25 has been one of the strongest cycles in recent memory, producing several massive sunspot groups. The current large region turned Earthward (Active Region 3780) is now easily visible with eclipse glasses… no magnification needed. Cycle 25 started back in 2019.

That ‘Old Faithful’ of meteor showers the Perseids peak early next week.
Great ready for one of the surefire astronomical events of 2024, as the peak for the Perseid meteors arrives next week.
To be sure, the Perseids aren’t the most intense annual meteor shower of the year; in the first half of the 20th century, that title now goes to the December Geminids. What the Perseids do have going for them is timing: they typically arrive in early August, before the academic year starts and during prime camping season, which finds lots of folks out under warm summer skies.

Why July 2024 is a prime time to see distant Pluto before it fades from view.
Lots of the ‘wow factor’ in astronomy revolves around knowing just what you’re seeing. Sure, a quasar might be a faint +14th magnitude point of light seen at the eyepiece, but it’s also a powerful energy source from the ancient Universe, billions of light-years distant.
The same case is true for finding Pluto. Though its 0.1” disc won’t resolve into anything more than a speck in even the most powerful backyard telescope, knowing just what you’re seeing is part of the thrill of finding the distant world.

The ‘Great North American Occultation’ sees the Moon blot out Spica Saturday night.
Few events in the sky transpire as quickly as occultations. While the path of the planets may move at a leisurely pace, and the orbits of double stars may be measured in terms of a lifetime or more, occultations are swift vanishing acts.
North American observers have a chance to witness just such an event this coming weekend, when the waxing gibbous Moon passes in front of the bright first magnitude star Spica.

Mercury puts on one of its best apparitions for 2024 this month.
Where have all of the planets gone? The late evening fall of dusk in early July also sees a sky seemingly vacant of familiar naked eye planets. Mars, Jupiter and Saturn are now denizens of dawn, and will stay that way for most of the remainder of 2024.
But two challenging planets are now emerging low to the west at dusk: Mercury and Venus. The two interior worlds are now mounting a slow return, as the hunt is now on the recover the two after sunset.

One proposal offers a unique method to directly image ExoEarths, or rocky worlds around nearby stars.
It’s the holy grail of modern exoplanet astronomy. As of writing this, the count of known worlds beyond the solar system stands at 6,520. Most of these are ‘hot Jupiters,’ large worlds in tight orbits around their host star. But what we’d really like to get a look at are ‘ExoEarths,’ rocky worlds (hopefully) like our own.
