Light Pollution: I Hate You

Drive 3 hours east of Los Angeles and you can still see the overwhelming glow of LA and its seemingly endless sprawl of suburbia. This short exposure captures the incessant light that too many people believe we need all throughout the night and the wee hours of the morning. The truth of the matter is that artificial light at night is mostly unnecessary, is damaging, and is worsening. It impacts human health as well as the health of other species. It's wasteful of electricity, and it does little to thwart crime.

And on a less tangible level, it distances us from our evolutionary roots. For all of human history, we've had a connection to the night sky. We gazed at it, wondered about it, described it, and have come to understand many of its mysteries... only to wipe it from our heritage and from our collective memory over the course of just a few decades. Now we gawk at photos of the night sky because it's such a rare and odd site to so many of us.

So get out there. Go see the night sky and connect.

Read up on it a little:

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).
