Re: Where New Horizons is
I’m just not sure how specific stars in this video, a very small percentage of those visible, cyclically pulse in intensity many times each. I don’t see anything unique about them in terms of apparent size/intensity etc. that might help produce this effect from interpolation or other video technique...

Approach to Ultima Thule
There's a new movie of the approach/recede from Ultima Thule that has what look like a number of variable stars in the background (I counted 18 so far): http://pluto.jhuapl.edu/images/main-page/fullmovie-mainpage2.mp4 Another link with more information, noting there are synthesized frames in there a...

Re: APOD: NGC 6744 Close Up (2018 May 31)
Hey Rob, I suppose you could take adjacent pixels that lie outside the detected star/cross occultation pattern and blur/average/interpolate them into the locations of the offending stars. Then it might just appear as slight smudges when inside the galaxy of interest, and black when outside. If neede...

Re: APOD: NGC 6744 Close Up (2018 May 31)
As nice as that picture is, it would be interesting to see a view from outside our galaxy by "removing" foreground stars. Maybe software could be written to identify them (sharp points of light) then mask them off.

Check out the perfect "H" of stars at the top of the Milky Way arch. You have to get the full resolution image to see it. Maybe it's the photographer's watermark?

Re: Interstellar Asteroid 1I/2017 U1 'Oumuamua
Just watched the above NASA video and noticed the scientist saying there are no other known asteroids shaped like this in the Solar System. Given that there's been over 100,000 asteroids observed (https://en.wikipedia.org/wiki/Asteroid#Computerized_methods) and assuming many have had their shapes es...

Re: APOD: A Year of Full Moons (2017 Nov 05)
I had no idea that the apparent view of the moon rotated around 90 degrees over the seasons. This is way more than subtle and maybe why people sometimes have a hard time to recognize Mikey Mouse on the Moon.

Re: IfA: Interstellar Asteroid or Comet 'Visits' Solar System
Probably all those gravitational vacuum cleaners have swept up most of the interstellar grit.
It might be interesting to directly see what the rest of the universe is made of by landing on one. Might be a real mess if it turned out to be antimatter...

Re: IfA: Interstellar Asteroid or Comet 'Visits' Solar System
It's seems hard to believe interstellar asteroids are this rare. Maybe there are waves of them that come in from old exploded stars.

Re: APOD: Crossing Mars (2016 May 02)
That makes for a rough hike. Great imagery.
I hope I get to experience in my lifetime an immersive video of not only the sights, but sounds of a rover and whatever the slightest whisper of atmosphere there may be. Wouldn't that just be amazing? Who cares if it takes four months of uploads.

Re: APOD: Heliopause Electrostatic Rapid... (2016 Apr 16)
It would be neat to model the wire shape, although I think catenaries are suspended by more than one point. Probably similar to a windmill.
There's probably a solution for this whole concept if you work on it long enough, just work smarter!

Re: APOD: Heliopause Electrostatic Rapid... (2016 Apr 16)
Maybe that's the trick, looking at that meteorite curve drop off at very small sizes, extremely small vehicles with hair width wires might work. Wires also double as a highly focused high gain antenna to earth.
Wonder how much power could be generated onboard given that current flow.

Re: APOD: Heliopause Electrostatic Rapid... (2016 Apr 16)
Neat idea. Someone should figure out the probability of a cut wire, if significant what you'd do to counter the loss of weight.
