In case you were concerned, there are no large* asteroids, comets, or anything else of a cosmic origin on a destructive collision course with Earth in the foreseeable future – and that most certainly includes this coming September.
Let’s take a look back at our own planet for a moment with this stunning photo captured from the Space Station. This shot, taken on the night of Aug. 10, 2015, shows lightning flashes in thunderstorms over southern Mexico. Along the right edge bright red and purple streamers can be seen extending high into the atmosphere above a particularly powerful flash: a full-on “red sprite” caught on camera!
On July 29, with ESA’s Rosetta spacecraft in orbital tow, the 2.5-mile (4-kilometer) -long Comet 67P/Churyumov-Gerasimenko fired its brightest jet yet since Rosetta’s arrival just over a full year ago, on Aug. 6, 2014.
Most of the images of 67P showing jets and outgassing activity released over the past few months have been edited to boost jet visibility but this recent flare-up needed no such enhancement. Rosetta’s high-resolution OSIRIS camera had no problem capturing the brief ice capade from 115 miles (186 km) away.
On August 10, 1966, NASA’s Lunar Orbiter I launched from Cape Canaveral aboard an Atlas-Agena D rocket, the flagship spacecraft of a program designed to map the Moon and investigate intended landing sites for the planned Apollo landings, including helping determine the risks from micrometeorite and radiation exposure. Over the course of the next twelve months and five successful missions the Lunar Orbiter program photographed 99% of the Moon’s surface, both nearside and far, to a resolution as fine as 1 meter – which at the time was ten times better than what could be achieved from Earth.
Lunar Orbiter I was also responsible for sending back our first views of Earth from lunar orbit, one of which can be seen above.

I’m in a debunking mood today, probably brought on by the seasonal “double Moon hoax” that raises its oh-so-wrong head every August. (Read more on that nonsense here.) So here’s one more thing to say “NO” to: giant alien cave crabs on Mars.
Apparently there’d been some buzz recently in the “space woo” circles online over an image acquired by NASA’s Curiosity rover showing an exposed rock outcrop on Mars. In the image, tucked into a corner between a couple of larger rocks, is an oddly-shaped… thing… that some of the more “open-minded” (sarcasm intended) viewers have claimed is an alien organism, not unlike some that have made appearances in various sci-fi films over the years.
I’ve included the original Mastcam image above with the object in question outlined and “enhanced” on the left. Is this indisputable evidence of tentacled cave dwellers on the Red Planet? Hardly.
No, no, no…a thousand times NO: Mars will not become a “second Moon” in the sky on August 27. It won’t this year, it didn’t last year, and it didn’t in the past dozen years since this silly yet strangely perennial cyber-legend (yes I just used the prefix “cyber”) first started circulating on teh interwebz. I don’t know why it keeps rising from the e-dead every year, some years more omnipresently than others, but the bottom line is it simply won’t happen. Not this time, not ever… the Solar System just doesn’t work that way. (And good thing too!)
