Re: APOD: NGC 5189: An Unusually Complex... (2012 Dec 19)
Now this is what happens when you try to reverse temporal trajectory in your TARDIS without first pausing and offsetting your physical coordinates by at least one external diameter. Your time capsule overlaps itself while traveling in opposite temporal directions, paradox ensues, and the picture sho...

Re: APOD: Barnard Stares at NGC 2170 (2013 Jan 19)
The title "Barnard Stares...." hints at something about Barnard's Star, not Barnard's loop.
What about "Barnard Looks....", "Barnard Leers....", "Barnard Glares....", or something else alliterating with "loop" or at least not with "star"?

Re: APOD: Orion over El Castillo (2012 Dec 21)
Canis Minor and Canis Major are his dogs, the one in front is called Procyon. They chase Lepus, the hare, although Hyginus says some critics thought this too base a prey for the noble Orion and have him pursuing Taurus, the bull, instead. The Mithraic iconography features Mithras killing a bull, su...

Goldilocks thought that only Little Bear's stuff was "juuuust right!"inertnet wrote:They might think that they're unique too.
But Papa Bear's stuff was just right for Papa Bear, and Mama Bear's stuff was just right for Mama Bear.
That aspect of the "Goldilocks" story is worth remembering.

This histogram depicts the estimated fraction of stars that have close orbiting planets of various sizes. The number of Sun-like stars with Earth-like planets in Earth-like orbits is surely much less,.... Closer orbits around colder stars, or more distant orbits around hotter stars, should provide ...

What if Phobos has a dense round core that's worked its way entirely loose from the thin shell? Should it be renamed "Tinklebell"? Interesting that the "freshly uncovered" surface should be a silver-gray, unlike the Mars-reddish of the other impact areas. Almost as though the cap...

Tourists and vanity: it afflicts even our machines . Travel all the way to an alien world, stop in the middle of an alien landscape, and take a photo of yourself .

It's just that in this physical realm, i just can't see as far as Pluto. You can see a whole lot farther than Pluto, viz. any stars you see in the night sky. Perhaps if conditions were just right, with a brand new super nova off in the distance behind Pluto... Nah! I still wouldn't be able to see P...

Re: APOD: Phobos: Doomed Moon of Mars (2012 Oct 28)
One thing I thought odd, given Phobos's presumed origin as a captured asteroid, was its similarity in reddish color to Mars. A number of other asteroids have been photographed, and appeared to be gray. Was this only due to monochrome film?
