Da Vinci Glow

36 Comments

Ever heard of a Da Vinci Glow?  I hadn’t… even with my dad’s interest is all thing astronomical!

It’s a real thing… It’s happens around sunset when a crescent moon is on the horizon, but the outline of a full moon is visible.  It’s called a DaVinci Glow because… wait for it… Leonardo was the one to hypothesize why it occurs.

The glow is caused by light reflecting off the Earth onto the moon.  Sounds weird, right.  Earthshine is light emitted by the Earth after the sun has gone down.  Because Earthshine is actually brighter than moonlight, the reflection “fills in” the crescent.

Although Da Vinci Glow is not rare, there are a few requirements.  It’s easier to see when there is a waxing or waning crescent during clear skies.  The fly in the ointment is that enough of the Earth needs to have cloud-cover to get the best view.  Apparently Earthshine is reflected more by the clouds of our planet than by the land or water. 

Since we have a waxing moon starting later this week, we’ll have the best chance of seeing the Da Vinci Glow this month!

Have you ever noticed this phenomenon?  Anything else in the night sky interest you these days?

Project Hail Mary

17 Comments

I don’t to think of myself as any author’s shill but…..

Spent pretty much all of three days doing not much besides reading Project Hail Mary by Andy Weir.  I’d say I couldn’t put it down but was listening to it on CD so not physically holding it.  I don’t want to give much of a recap because there are about a million spoiler alerts but suffice it to say, here is a list of why you might like it if:

  • You liked The Martian
  • You like science fiction
  • You like stories about space
  • You like science explained in a way you can understand it
  • You like humor mixed in with your science
  • You like a main character who is flawed but still very likeable
  • You like books that draw direct comparisons to current issues without bludgeoning you with them
  • You like stories that draw out a little of your emotion

I sent an email to Andy Weir telling him how much I liked it (and he emailed me back within a couple of hours!).  If there were an Andy Weir Fan Club, I suppose I would now officially be a member.  With today’s social media, are there even fan clubs anymore?

What’s the last book you couldn’t put down?

Half a Giraffe

59 Comments

You’re giving a announcement to the press about a small asteroid that has managed to get through our atmosphere without completely burning up.  The small space rock is named 2022 EB5 and hit above Iceland last Friday causing a boom and a flash of light as it whizzed across the sky.

You haven’t found any evidence of the asteroid actually making it all the way to the ground, but you want to make folks feel secure about how little damage it would have caused.  So you describe the size of the asteroid as small, 10 feet/3 meters across, “half the size of a giraffe”.

What?  I think a lot of people have probably seen a giraffe in a zoo and have a fairly good idea of how big a giraffe is but it’s certainly not the first thing I would think of when trying to tell someone the size of something.  Especially when 10 feet or 3 meters isn’t that hard to imagine.  But a giraffe…. actually HALF a giraffe?

Isn’t half a giraffe the same as a baby elephant?  Or six dolphins?  Are we picking on animals?  Should we say the asteroid is the size of a Volkswagen Beetle?  And even if we stay with giraffes are we talking half a male giraffe, a female giraffe, a dwarf giraffe?  Are we talking head to halfway through the torso or halfway through the torso to the feet?

Possibilities are endless.

What do you think is a measure of size that the world is missing out on?

Dinosaurs to the Moon

I wasn’t on the trail much over the weekend; I was following a livestream on YouTube.  (I can’t even imagine what I would have thought if I had read that sentence 20 years ago!)

15 years ago, after reading a book by John Green (I think it was Looking for Alaska), I started following him and his brother, Hank, on their YouTube channel called VlogBrothers.  Hank is the brainchild behind SciShow, another fabulous channel and together the brother have created multiple other channels and platforms.  They manage and ship creations by a variety of artists, from their DFTBA (Don’t Forget to be Awesome) warehouse, among many other things.  Their following is called Nerdfighteria and I have to say that they were a big factor in my finally being able to own my nerdiness and feel that it was OK to admit to my smarts.  I say it calmly but it was actually a fairly big turning point in my life.

Both John and Hank are thoughtful, kind and generous – the year I started following their vlog, they decided to do a weekend event on YouTube to raise money for good works.  They invited people to send in videos to the channel to support charities; we would watch and vote on the videos and, if we could, send in money.  At the end of the weekend, they split up the money among the top voted groups.  And they did a livestream the entire weekend to encourage folks to watch the videos, vote and donate.  They called this Project for Awesome. 

And 15 years later, it is still awesome although a little more cohesive these days.  The first 24 hours of donations go to a couple of specific organizations that Nerdfighteria have supported for many years and then the second 24 hours of donations gets split up among the top groups whose video have been voted on.  Lots and lots of perks donated by various online creators.  The livestream is a little surreal… YouTubers setting up goals and challenges.  My favorite is Destin whose vlog “Smarter Every Day” I have watched for years.  Donations during his 2-hour stint get you a plastic dinosaur magnet with your name on it that gets sent to the moon on an electronic pulley system. Honestly I don’t even know how to describe it.  Suffice it to say it’s just hysterical and the donations just blast in during his time.

Anyway, I watched quite a bit of the livestream, including staying up too late both nights and then watching early in the morning.  As the project rolled toward its end, donations again ramped up as John and Hank finished up the livestream with a lot of thanks and champagne poppers and confetti.  About 15 minutes before the end, the counter clicked over the $3 million dollar mark.  I have to say I got a little verklempt.

The happiness that I get from being part of the nerdfighter community makes me think a lot about the Trail and my baboon companions there.  I am not a serious member of the group and I only know one other nerdfighter personally but as a group they follow their leaders… they are kind and thoughtful and generous as a whole, exactly like those I know on the Trail.  No nastiness, no name calling, no mud slinging.  Wish I could spread that feeling out to the whole world.

Tell me about some other nice, thoughtful, kind folks you know!

Too Late?

Asteroid 1994 PC1 whizzed past us yesterday at 43,000+ miles per hour.  Apparently compared to the asteroids that swing by almost every day, 1994PC1 is fairly large to be so far outside the asteroid belt.  NASA has been watching it for years (I’m guessing from it’s name, since 1994) and since none of us got warnings about impending asteroid/earth collisions the last few days, they are quite aware that relatively speaking while it’s coming close to us, its closest pass will be five times the distance between us and the moon.  According to scientists “if you aren’t worried about the moon crashing into your house this week, you shouldn’t be worried about this either”.

I guess we might have a closer call with a much larger asteroid in 2028.  That news actually hit the stands back in 1997, just a year after a big scare when 1996 JA1, an asteroid the length of two football fields, passed by at only 300,000 miles with not much warning.  This might account for a bunch of the asteroid movies that came out in the next couple of years (Deep Impact, Armageddon, Asteroid, Judgment Day to name a few). 

I’m not a big disaster film buff (although technically if they divert the asteroid, it’s not really a disaster flick, is it?) but I did see a couple of these.  It’s an interesting concept – pushing off an object that is traveling 43K miles an hour.  And I don’t really follow this stuff closely so I don’t know if there is an object that NASA is actually worried about.  And I wonder, would they tell us if there were?  Not sure what in heck we, as citizens of the planet could actually do to prepare.  I mean, I assume we’re smarter than the dinosaurs, but there sure wasn’t anything they could have done differently.

Which do you worry about more – asteroids or a zombie apocalypse?

Jumping In

37 Comments

Al the discussion about gardening on Mars and The Martian by Andy Weir made me think.  If I were sure I could get back, would I want to try Mars?  And better yet, if I could beam to Mars and back, instead of spending more than a year on a spaceship each way, would I want to try Mars?  I might, since my biggest issue is the travel part.  And the getting home part.

By now, of course, I’m pretty far down Fantasy Road and I found myself thinking about whether I would want to change places with any other movie character, or tv character or character in a book. 

Again, part of my decision is based on the absolutely certainy that I am not putting my life in danger and I would be able to get back home.  Kinda like the holodeck in Star Trek where you just say “computer, end program” and the door to the ship’s hallways opens right up.

That being said, I can think of LOTS of characters I’d like to be for a week or so.  Scarlett O’Hara from Gone w/ the Wind, Scout from To Kill a Mockingbird, Ren-Marie from any of the Three Pines mysteries, Frodo from Lord of the Rings, Lawrence from any of the Temeraire stories (except Australia – that one stunk)…. I could go on and on.  Of course there are a lot of stories I prefer from a reading distance – pretty much anything during WWII and Vietnam, anything where the character is scared/threatened/blackmailed through the book or movie. Anything that is too gory or gruesome.  And if it’s a book I really didn’t like then I definitely don’t need to swap with those characters ever.

So what about you?  Any character you’d like to be for a week?

Where No Ketchup Has Gone Before

41 Comments

“First came the billionaires, then the movie stars — now ketchup is making its mark on the space race.”  (CNN November 8, 2021)

At first glance, this seemed like a silly story – Heinz had made “Marz Edition” of their ketchup using tomatoes that were produced in a controlled environment similar to what plants could expect if they were growing up on the Red Planet.

But turns out this was a serious experiment by 14 astrobiologists as part of long-term food harvesting  strategy for NASA.  I guess astronauts and Mars pioneers need a little more than freeze-dried ice cream (which is awful, by the way) to get by.

The ketchup will not be available to the public but there will be a big taste test tomorrow – if you are Twittered or Instagramed, you can watch it at 10 a.m. ET.  For the rest of us, we’ll just have to dream.

If you have a couple of Martian acres, what would you want to grow (and would you want to garden in person or from a distance)?

Fresh Air

49 Comments

Our son and his family just moved to a town four miles outside Brookings, SD. Brookings is a university town with a population of 22,000 people. The town to which they moved has around 800. They commute to their jobs in Brookings.

Brookings is in the middle of the prairie. It is not industrialized. The nearest larger towns are 50 miles away. Both are pretty modest in size. We are talking sparsely populated. Son and Dil insist that the air in their new little town is noticeably cleaner than in Brookings. They adore the quiet. They love looking outside and seeing the stars. There is very little light pollution. Unless they fence their yard, any gardens they plant will be eaten by deer and raccoons.

We are so happy for them in their new digs. I think their assessment of the air quality may be a little bit exaggerated, but it is nice to see them enjoying their life. They are so proud of their new home. I grew up in a small town downwind from beef and pork processing plant, so I know how important air quality can be to life satisfaction.

What are your favorite indoor and outdoor smells? What are the most polluted and cleanest places you have lived? What constellations and stars can you identify? When are you most likely to kvell?

He Said She Said

90 Comments

I spent an hour or so at Urgent Care yesterday (not a big deal – just wanted to be reassured that my self care was OK and to get a tetanus booster.

While waiting I noticed a woman go in and out of the UC door a few times; she was wearing a Darth Vader smock.  Long gone are the days when everybody is required to wear white!  When it turned out that she was the nurse who was going to rewrap my hand and give me my shot, I was elated.  I told her how much I like her smock and she told me about her other Leia smock.  We traded our favorite quotes from Star Wars.  Since she is a Darth fan, hers is “I find your lack of faith disturbing.”   I like that one but I do gravitate to Yoda “ Do.  Or do not.  There is no try.”

On the way home I was thinking about this encounter (which was really the highlight of my day) and how many times I use quotes from my favorite movies.

  • “On the side.” When Harry Met Sally
  • “Badges? We don’t need no stinkin’ badges.”  Treasure of the Sierra Madre
  • “You know, assholes.” Blazing Saddles
  • “Candygram for Mongo.” Blazing Saddles (You’d be surprised how often you can make this work.)
  • “You overestimate both of us.” People Will Talk
  • “Snap out of it.” Moonstruck
  • “Be afraid. Be very afraid.”  The Fly
  • “There will be blood tonight.” Princess Bride
  • “We are men of action. Lies do not become us.”  Princess Bride  (Note: I say this to myself.  Not aloud.)
  • “You keep using that word, I do not think it means what you think it means.” Princess Bride   (Again, never said outloud.  And I say it to myself with Mandy Patinkin’s accent.)
  • “Now they’re practical.” Romancing the Stone
  • “Not exactly firing on all thrusters.” Star Trek IV
  • “Fun fun fun til her/your daddy takes the T-Bird away.” (yes, I know this a song not a movie, but, what the heck, it’s my blog post…..)

Any quotes from movies (or tv or book or songs) that you find yourself using in every life?

Rabbit Whimsy

51 Comments

Last month Bill (I think it was Bill) mentioned Voyage to the Bunny Planet by Rosemary Wells.  It had been in print a few years before I was first read it to Child, but I remember that we had it from the library at some point.  The Hennepin Library doesn’t own a copy any longer but I was able to get it through InterLibrary Loan and I’m liking it so much that I’ve ordered myself a copy.  (I have a very modest children’s book collection – based solely on what I like).

There are three stories, each featuring a young bunny who has had an exceedingly bad day —  never-ending math class, horrible cousins, medicine that tastes like gasoline.  At the end of these bad days, the young bunnies wish for a visit to the Bunny Planet.  There they are greeted by the kind Queen Janet who invites them in with a “Here’s the day that should have been.”  Each bunny falls off to sleep with the visions of a perfect day dancing in their heads.

At the beginning of each story, there is a rabbit quote like this:

It is the first duty of a flagging spirit to seek renewal
in the latitudes of whimsy.  I, for one, dream on
beyond the give planets to a world without wickedness;
verdant, mild, and populated by amiable lapins.
Benjamin Franklin

The other quotes are from Rudyard Kipling (“The captain fell at daybreak, and ‘e’s ravin’ in ‘is bed, With a regiment of rabbits on the planets round ‘is ‘ead.”) and Galileo (“I designated this heavenly body “Coniglio,” but alas, never saw it again.”)

It’s gratifying to see rabbits making the grade in heavenly literature but I think it’s fascinating that Benjamin Franklin dreamed of whimsy and thought a perfect world would be a bunny haven.

I say whimsy all around!

Tell me about your “day that should have been” and how your perfect world would look?
