For some unknown reason, I have a desire to capture sunrise on Tycho, the prominent rayed crater on the moon. Since it’s unlikely I’ll be able to afford a trip there anytime soon, I’ve been pursuing this remotely, but what it means is capturing a particular phase of the moon at just the right time. Shown above, we have the moon from yesterday evening and tonight,

Heads up!
On Friday, September 6th, at 11:27 PM EDT, NASA will be launching the Lunar Atmosphere and Dust Environment Explorer (LADEE) satellite from the Wallops Island launch facility on the Virginia peninsula. Viewers on the east coast of the US may be able to see it as it heads towards lunar orbit, since night launches allow the exhaust plume to be seen from great distances.
Alien psychology
I feel slightly guilty about appending an ‘astronomy’ tag to this, because it’s going to seem not just distantly-related, but wholly out of place to some reading. Yet, there really is a legitimate bearing, as I hope to demonstrate. So let’s take a brief look at the history of extra-terrestrial encounters, because sometimes it helps to know the perspectives of the time.

Extreme HDR
“HDR” stands for “high dynamic range,” a photo editing technique used to combat the increased contrast that all standard photo methods are prone to – see a greater explanation here. Sometimes it’s used to produce unrealistic images with light levels that really
Moon of steel
Yeah, it was a non-event, even in areas that had good visibility – mass media really can’t handle astronomical events very well, but much worse is the social-media-fueled rumor mill. “Mars will be so close it will appear to be the size of Jupiter in the sky!” yeah, yeah…
Now, a curiosity. The haze is from the moon shining through scattered thin clouds, but the stepped
The dude is hot. Or cold. So, so cold…
A few years back when I was still following the Bad Astronomy blog, Phil Plait posted an image of odd geological features on Mars, along
Too cool, part 18: Hubble turns 23
Twenty-three years ago today, the Hubble Space Telescope was launched into low-earth orbit (meaning about 555 km, or 345 mi, above the surface of the Earth.) Since that time, it has produced perhaps the largest body of work of any single telescope, and certainly some of the most detailed. And just recently, NASA released a sweetheart.
Let’s start with some perspective. Everyone (who matters)
Not the right kind of composition
Just a quick image from tonight, as Jupiter passed close to the moon. Or at least, from the given perspective of one position in the universe presently occupied by Earth. Jupiter has often been much closer to the moon, distance-wise, even when not visible in the sky at all.
This is admittedly both not very good, and a digital composite. The reason for the composite is the wide disparity in light
Chasing megapixels
Some time back, I’d started a post on this subject, partially in response to a thread somewhere, but when I took too long to finish it I realized it was, in webby terms, no longer current, and simply let it go. But after another prompting, this time from The Straight Dope, I decided it’s worth pursuing anyway, and may provide a little insight into the whole digital photography thing.
Just a bit of trivia
The passing of Neil Armstrong the other day brought a flurry of articles and post featuring the same image, one that’s been featured literally uncountable times since 1969. You know the one that I mean…
Those that are really into the space programs, especially the Apollos, know that this is usually misrepresented. This is not the first footprint on the moon. No, it’s not the first
