Trick or Telescope

HalloweenTelescopePumpkin 20191031

I was hoping we would get a clear night for Halloween, so I carved my pumpkin with an owl sitting on a telescope.

As predicted, the cold front blew through last night, and we got a cold but clear night for Halloween.  So I set up my telescope as an extra Halloween visitor treat!  Great views of the Moon, Jupiter, and Saturn.  Saturn’s rings looked especially great.

I tried taking some pictures through the telescope eyepiece with both my phone and my camera.  Neither turned out nearly as good as the view in person.  Oddly, the moon picture came out better on the phone, but the Saturn picture came out better with the camera.  On the other hand, I could get a much better Moon picture with the camera without the telescope, but haven’t managed to get nearly as good a picture of Saturn with the camera solo.

Fact and Fiction in “The Annual Argument at the Deextinction Board Meeting”

I hope you’ve had a chance to read my hard science fiction story about deextinction in the latest Analog.  Most of the story is based on my research, but I did make a few parts up.  Here’s the lowdown on fact and fiction in the story:

Is there a single board where people pitch deextinction plans to get funding?

Not to my knowledge, and in general that’s not how research funding works (there are lots of independent groups deciding what research to do, so there might be boards but not one single board).  I made that part up.

Is deextinction a real science?

Yes, it is.  There are groups currently working on deextincting the Wooly Mammoth, Passenger pigeons, and other creatures.

Are there people trying to determine which species to deextinct?

Yes, there are people making lists.

Was the Irish Elk a real animal and is it on the lists?

Yes, it was and is.

Are there people studying the ethics of deextinction?

Yes, there are.  There are groups arguing against it and groups arguing for it.  There are also people studying the ethics to produce guidelines on what species to deextinct.

Is Pleistocene Park a real place?

Yes it is.

Did the Neanderthal Y chromosome really not make it into the human genome?

According to one study, it did not.  The paper speculates that homo sapiens could not carry male fetuses with Neanderthal Y chromosomes to term.

Do the Irish Elk have the same issue with the Y chromosome?

Not to my knowledge.  I made that bit up.

Is the genus name for saber-toothed cats really smilodon?

Yes!  Smilodon fatalis.  Isn’t it a great name?

Was there really a saber-toothed salmon, and is its genus name really smilodon?

Yes, there was.  Alas, it has apparently been renamed.

I hope you’ve enjoyed this tour through deextinction links! I enjoyed doing all the research that went into this story.

Corkscrew Meteor – 5 September 2019

Corkscrew Meteor 20190905

Recently, when I’ve tried to photograph meteor showers, I’ve taken hundreds of (automated) shots and have been lucky to get one or two nice meteors.  Last night, I took 36 pictures, mostly trying to find a comet, and I ended up with three. I especially like this shot of a corkscrew meteor, which I think is the neatest I’ve ever taken.

Jupiter and the Moon – 5 Sept 2019

 

Moon-Jupiter 20190905 v2

Moon-Jupiter 20190905 v1

 

The sky was clear last night, so I went out to get a lovely shot of the conjunction of the Moon and Jupiter.  I also searched for comet SOHO P/2008 Y12, but was unable to find it. It should be getting gradually brighter, though, so I’m going to try again!

Without resorting to neutral density filters, I could either pick up the detail in the Moon or Jupiter’s Moons.  Which do you like better?

Eta Aquariid Meteor May 5, 2019

While the web sites had various predictions of the peak of the Eta Aquariid meteor shower, the weather prediction was unambiguous: if I wanted to try to see them, before dawn Sunday May 5 was the time.  So even though we had some light clouds overhead, I got up at 4:30 AM to try to catch some meteors.  I saw one and maybe-saw four more.  Happily, the camera caught one as well.
