Astronomy at the Beach 2022 on the VO Calendar
I’ve added Michigan’s Astronomy at the Beach event, and the remote presentations I’m giving during it to the calendar on the VO website.
I will not be attending the live event – I will be hosting a couple Zoom sessions during the event:
- A Tour of the Solar System – I’ll visit all the usual places, and several unusual ones in the solar system and beyond using SpaceEngine. Note: I want to give this presentation to a LOT of classrooms this year!
[Friday Sept. 16 6:00 PM EST] [Saturday Sept. 17 6:00 PM EST]
- A Mission to Mars – I’ll design, build, launch, fly and land a probe to Mars (Er, Duna) in Kerbal Space Program. Along the way, I’ll show some basic orbital mechanics. Hilarity is a given.
[Friday Sept. 16 7:00 PM EST] [Saturday Sept. 17 7:00 PM EST]
Morning: Venus appears low above the eastern horizon before dawn.
Morning: Mars and the Pleiades star cluster appear nearly overhead in the predawn sky.
Morning: Jupiter rises in the east, and Saturn appears above the horizon in the southeast after sunset
Morning: Jupiter appears high in the southwestern sky before dawn; Saturn sets in the west-southwestern sky shortly after 5:00 AM.
Evening: A thin crescent Moon appears above the west-southwestern horizon on August 30th and 31st.
Evening: The crescent Moon appears near the star Antares in the south-southwestern sky after sunset on September 3rd.
Evening: The Moon appears in the “handle of the teapot” of the constellation Sagittarius in the southern sky after sunset on September 5th. Credit: Bob Trembley / Stellarium.
- The Moon is a Waxing crescent – visible low to the southwest in the early evening.
- The First Quarter Moon occurs on September 5th – visible high in the southern sky in early evening.
- After September 5th, the Moon will be a Waxing Gibbous – visible to the southeast in early evening, and up for most of the night.
If you click on the Moon image above, or click this link, you will go to NASA’s Moon Phase and Libration, 2022 page – it will show you what the Moon looks like right now. If you click the image on that page, you will download a high-rez TIFF image annotated with the names of prominent features – helpful for logging your lunar observations! (See below)
The Sun has five named sunspots, again – AR3088 is VERY active, and rotating out of view.!
Spaceweather.com says: “Sunspot AR3089 has a delta-class magnetic field that poses a threat for X-class solar flares.”
The Sun seen in 193 angstroms on August 29th.
An active region with HUGE coronal loops and blowing flares all over is rotating out of view on the Sun’s limb. Three large coronal holes are spread out across the Sun’s face – one hole stretching down to the south pole. A flare blows a temporary hole in the corona.
The Sun seen in 304 angstroms on August 29th.
Prominences everywhere! The active region mentioned in the other video is very obvious in this video – WOW!

First JWST Exoplanet Transmission Spectroscopy Data Available in the NASA Exoplanet Archive!
We’ve added new WASP-39 b spectra from NASA’s Webb Telescope to our Transmission Spectroscopy table, which provides a single place to access publicly available spectra taken by various telescopes for this object, including NASA’s Hubble and Spitzer, the Very Large Telescope, and Chile’s Observatorio Astronomico Nacional.
Pro Tip: Enter WASP-39 b in the Planet Name column to filter the table to view only the WASP-39 b entries.

Messier Tour: M27 – The Dumbbell Nebula
Messier 27 (M27), also known as the Dumbbell Nebula, Diabolo Nebula or Apple Core Nebula, is a planetary nebula in Vulpecula. The Dumbbell Nebula is large in size and quite bright, which makes it a popular object among amateur astronomers. It can be seen in binoculars and small telescopes.
The nebula covers an area of 8 by 5.6 arc minutes of the apparent sky and has a linear radius of 1.44 light years. Its faint halo stretches out to more than 15 arc minutes. M27 lies at an approximate distance of 1,360 light years, or 417 parsecs, from Earth and has an apparent magnitude of 7.5. It has the designation NGC 6853 in the New General Catalogue.
Messier 27 is the second brightest planetary nebula in the sky, second only to the Helix Nebula in Aquarius, and probably the easiest one to observe because it has a higher surface brightness than the Helix and is therefore easier to find. – messier-objects.com
The name Dumbbell comes from the English astronomer John Herschel, who observed the nebula in 1828 and compared its shape to that of a dumbbell.
The Dumbbell Nebula lies just to the south of the star 14 Vulpeculae. It can be seen in large binoculars, and some of its details are visible even in smaller telescopes. The best time of year to observe M27 is summer as it lies within the Summer Triangle, a prominent asterism in the summer sky formed by the bright stars Altair in Aquila constellation, Vega in Lyra and Deneb in Cygnus. – messier-objects.com
