This is one of those things about our planet that people would want to look up on the Internet, but won’t be able to if it happens.

Nuclear War Not Humanity’s Only Option
Aside from the insane invasion of democratic Ukraine by the Russians, there’s another pending catastrophe in store for humanity anywhere between this afternoon and the next 5000 years. Destruction from space rocks slamming into our atmosphere is a near certainty in our solar system, but we have technology that can sometimes detect them in advance, and other technology being tested this year that can divert collisions.
Here’s a really interesting theory about a now well studied destruction of an ancient city that made it into Biblical stories.
This year though, we’ve come closer to nuclear war than any other time I can recall. Take time time to enjoy the 1964 cold war comedy: “Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb”.
We shouldn’t stop worrying, or love the bomb, but it’s hard to know how much worry, anger, and hope to throw into one’s daily life right now.
Meteor Explodes Over Ocean in 2018
Solar Eclipse from Regina, SK
The eclipse today was visible from Regina, but not the totality available to Americans in many states.
My new Canon SX540 HS did a good job with a pair of solar eclipse filter glasses taped over the lens. The sunspot chain was very sharp and visible at 200X digital zoom, 80ISO.
I made a projector that worked well:
ADDED: Here’s 2012’s annular eclipse in Regina.
Astrophotography Is The Best
Jupiter is approximately 5.2 AU from our Sun, so almost 20 AU is pretty distant.
Have a look at what Mars would look like if it had a proper weather satellite.
Dramatic Jupiter Exploration Video
It’s done in the style of a fiction/action movie trailer, but this is for real.
One of the early results is this compressed/shifted audio depiction of aurora on Jupiter.
Mental Note: Design rocket so it doesn’t explode at 90 degree tilt
Rockets that land are a new thing, so it’s probably a minor oversight. No one was hurt in the blast. It’s hard to reuse a rocket that lands, if it then explodes.
To Be Left On The Moon
Some of these items found in Armstrong’s closet, were to be abandoned on the surface of the Moon.
More than four decades after the Apollo 11 moon landing, a cloth bag full of souvenirs brought back by astronaut Neil Armstrong has come to light.
Among the trove: a 16 mm movie camera from inside the lunar module that filmed its descent to the moon and Armstrong’s first steps on the lunar surface in 1969.
That camera “took one of the most significant sets of images in the 20th century,” said Allan Needell, a curator in space history at the National Air and Space Museum.
Aurora from a sunspot explosion
Last night the rating of the solar storm was “severe” according to spaceweather.com
Kp 8 is the strongest I’ve seen, unless it was 9 earlier this year for a storm I missed. The northern lights were to the south and east of Regina, which was good because I don’t have a clear view to the north.
Without digital zoom, the Sun is this big in my 12X zoom camera:
