Starship Asterisk*

Let's say I am a student in your advanced geometry class. How would you show the light path of this discovery ? Or would you be the devious professor and give it as a final examination ? Yes. Although I can understand why it is hoped/expected for a 5th and central image to appear, I do not understa...

... what about the small streaks at the image center, just above the rocket arcs? And what are the bright bluish flashes? ... each drop a "bomb" of reflected material once on their way up and once on their way down. I guess the two bluish explosions (and the in the center are the "on...

For the same reason that most of the moon walking images show no stars - the exposure latitude of the recording medium.

Considering that for so many millennia comets were thought to be harbingers sent from god(s) to foretell the fate of nations, it is difficult to imagine a scene showing more complete indifference to humans and to their concerns than this image of dark cliffs rising from the surface of this small wor...

Interesting choice of calibration marker. Until that coin there were no regular issue United States coins which contained a presidential likeness - as the founders did not wish to continue the European tradition of having the likeness of the monarch on coinage, for the president was not a monarch, a...

Astounding image, even if does not fit my imagined view of what a "dirty snowball" should look like, and given that there are not aliens milling about wondering what caused that bump. So much better seeing one's taxes being spent for exploration rather than destruction. The landing certain...

Very nice - though it goes by a bit fast: As does life, one supposes.

And, yes, the "scheduling" of the next equinox was as amusing to me as to some others.

All in all, a good start to the day.

Thanks

Mesmerising

Though did keep feeling that I was going to fall off the planet, as the moon was clearly upside down and going the wrong way.

Striking panorama and APOD crop ... but perhaps would be more satisfying with the saturation slider a bit more to the left?

Yes, one knows and does accept, eye of the beholder ...

Beautiful. Though I am sure the photographer may have been at first dismayed by the presence of the clouds, it comes together so well with a moon image having foreground, midrange and distance. Also, one of the few examples of HDR imaging which does not seem contrived and jarring in effect. Very nice.

I enjoy the way it feels like the earth turning, more than the stars rotating! Thanks! :ssmile: Yes. That is quite the illusion is it not. According to a recent international poll, 25% of Americans are aware of this illusion, and know that the stars do actually move around the stationary earth (as ...

Interesting in general, and as I am just getting into time-lapse photography, to me in particular. Watching the telescopes mysteriously point about, with the sky wheeling majestically behind them, was completely engrossing. The soundtrack adds nothing but distraction. Something Baroque or New Age ma...

Awesome! In the original, and now nearly completely lost, sense of generating an overwhelming sense of awe in the viewer. At least it was awesome after I hit the mute button on the keyboard to silence the horribly distracting noise of the soundtrack. Neither of these mesocyclones would I want to fly...

OH!

My.

Speechless.

The most amazing photo I have ever seen.

if the video appears gray

Well. It not only "appears" gray, but is grey.

Hopefully this will be sorted, as is a nice thought.

What is most amazing, and - this being the internet - what is most likely true, is that this is a cat: Look at the shape of the head - especially the shape of the ears and snout.

The only real question: Bastet or Shashti.

One in Five? At least of sun-like stars. Remarkable.

Any estimate of how many of these will have a Garden of Eden?

It is sobering to reflect that for having discovered these moons - defects in God's unchanging and perfect heavens - Galileo was sentenced to a life of house arrest by the Christian church.

It is fitting that this Little Planet projection is of an airfield, for Saint-Exupéry, who wrote and illustrated the haunting novella The Little Prince was an aviation pioneer. The book's cover art shows the Little Prince standing on The Little Planet and is, as far as I know, the origin of the name...

Welcome back! Have been using a mirror - but it is SO nice that the self-serving posturing unintelligent worthless salacious and mendacious idiots with whom we have entrusted the governing of our nation have finally ended their "ME, ME, ME" temper-tantrum and people can get back to work. A...

Yes, this is a stunning range of vision ... though within the current century this particular vista might well be underwater. The summary of the 2013 IPCC report was released today. Even in the watered down final version (watered down, as all of the governments making up the IPCC -Intergovernmental ...

Oh my goodness.

Does make one gasp.

And is best appreciated from the ground, as is a one to stay 10 away from unless turbulence is your thing.

Perhaps a bit heavy on the hdr?

Gasp.

Amazing - can anyone estimate the field of view, 180 I am thinking.

The "Bermuda Triangle" does not, in any meaningful way, exist. As Mr Kusche's research showed quite convincingly in his 1975 book the whole idea was invented by writers for men's adventure magazines in the 1960s. The triangle is no more real than new-age "energy" (what sort of en...

For, if flying saucers are as common as many believe, this should clearly be named the Flying Saucer galaxy. It is almost as though flying saucers were invented long after the identification of this object. Of interest, the pilot who reported what came to be called 'flying saucers' actually was not ...
