Astronomy in 2016

Not a lot has been happening here lately. Shame on me.

Let's take a look at what's coming up in Southern California for the first part of this year, astronomically speaking...

Mercury Transit – May 9
On the morning of May 9th, Southern Californians will get a good view of Mercury's transit across the face of the Sun. While a Mercury transit isn't quite the spectacle of a Venus transit (nor is it as rare), it's still an exciting event. Transits, like their more dramatic brethren, eclipses, are fantastic at providing rarely glimpsed perspective on a massive scale. Seeing two solar system bodies that are at opposite ends of the size spectrum provides a sense of scale that is difficult to achieve in any other natural way. During the transit, keep in mind that the Sun is roughly 93 million miles from us and Mercury is about 57 million miles from us. While Mercury is a lot closer, it's tiny size is fantastically dwarfed by the enormity of the Sun. Mercury will appear as little more than a black speck against the giant disk of the Sun.

From Southern California, the transit will be in progress already when the Sun rises at about 6AM on Monday, May 9th. But it will continue for about another 6 hours... so enjoy!

You'll need a telescope to view this transit so be sure you have proper filtration. Never stare at the sun and never point a telescope or binoculars at the Sun without proper solar filters in place.

RTMC Astronomy Expo 2016 – May 26-30
The west coast's granddaddy of star parties is gearing up for another round of festivities. Make your reservations now to stay overnight or spend the day at Camp Oakes, just east of Big Bear. Attend the numerous presentations, attend a workshop, hang out with friends, stargaze and maybe win a door prize! They're all par for the course at RTMC.

Lonely Speck Meetup at Trona Pinnacles – July 30
Lonely Speck is an excellent website for tips and detailed articles on photographing the night sky with little more than a camera and tripod. Ian Norman, the guy behind the site, is organizing a meet-up for anyone who wants to camp for a night, take photos of the sky, share tips, and see what others do to capture beautiful nighttime landscape photos with the best backdrop ever, the Milky Way.

RAS Outreach Events – Ongoing
Did you know that the Riverside Astronomical Society is extremely active in organizing and staging dozens of outreach events for schools, scouts, and the general public every year? It's true. Check out the latest schedule of outreach events and come out to one of our public events (like those at Dos Lagos Shops in Corona) to view the Moon and planets.

Nightfall Star Party & Imaging Conference 2016 – October 27-30
Everyone knows Nightfall doesn't happen until autumn, and that's not in the first part of the year! But it's mentioned here because you really need to make your reservations NOW! Nightfall is an extremely popular event and hotel rooms and RV spaces fill up quickly.

The Great American Total Solar Eclipse of 2017

American eclipses are about to be made great again! It's been about 38 years since there's been a total solar eclipse over the American mainland. And that one just grazed the northwest and northern plains before turning traitor and curving up into Canada. This time around, the path of totality runs essentially through the middle of the entire width of the continental United States, from Oregon to South Carolina. It will be one of the most witnessed total solar eclipses in history.
When: Monday, August 21st (exact times vary based on your location... more below)Where: An approximately 70-mile wide path that cuts through Oregon, Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina and South Carolina.Greatest Eclipse: Near Hopkinsville, KentuckyLongest Eclipse: Near Carbondale, IllinoisEclipse LengthShortest: West coast of Oregon at about 1 minute 58 secondsLongest: Southern Illinois at about 2 minutes 41 secondsHow is all the above in…

The Ambiguously Galactic Duo

M81 and M82 are two galaxies hanging out in the constellation Ursa Major, the Big Dipper. M81, on the right, is also referred to as Bode's Galaxy (for its discoverer, Johann Elert Bode). M82, on the left, is also know as the Cigar Galaxy.

Here are the wacky things about images like this one...

(1) Every single star you see in this image is in our own galaxy. It's easy to think you're seeing individual stars in M81 and M82 but that's simply not the case. At 12 million light years away, the galaxies are fairly close to us but they're still much too far to be able to resolve individual stars. Also, while there are such things as rogue stars that get flung out of their home galaxies due to gravitational disturbances, it would be quite rare for one to show up in an amateur astronomer's image.

(2) If your monitor is bright enough and calibrated well, you can see a lot of fuzzy patches, each of which is another galaxy!

Don't look at them too closely... M81 harbors…

Dusk in the Desert

Dusk in the desert can be a magical time. The sun has just set, temperatures continue to cool and pink and orange hues take over the landscape.

Star parties are a great way to experience that time of day. Here are a couple aerial shots as star party guests at GMARS gather and get ready for an evening of observing and imaging.

And, of course, here's an aerial video of the Landers area. It features the area at dusk, a 1-mile flight from GMARS to CS3 and back, flyovers of star party-goers, and a flight over Kate's Lazy Desert (at the end of the video).
