Starship Asterisk*

This amazing pattern is found in "octahedrite iron meterites and some pallasites" per Wikipedia. It's a beautiful structure from time long ago.

It might make for a fun APOD someday.

Are they sure those are land masses? If they were a less dense floating solid on a liquid hydrocarbon lake and the density of the liquid was fluctuating per season wouldn't they change buoyancy? Of course then the liquid hydrocarbon might expand also and rise its surface level which wasn't detected....

Phoenix, pigeon or something else ?

Lots out there! That's for sure

Guess it just takes a while to get things moving - galactically speaking?

How can we type galaxies by age – look further back in the universe?

The fractal appearance of the tributaries leading into the lake is surprisingly like that of Earth's water networks. Fractals must have more in common with geometry than chemistry.

But is "fractisity" a universal feature that is related to gravity or scale?

Chappy is quite a blast!

In the first link to the constellation Sculptor there is an image of R Scuptoris . R Scuptoris is an interesting sight. It almost looks like it could be a planetary nebula in the early period of its formation. If it does have a companion it would surely be affecting the shedding of its outer shell. ...

Why couldn't ancients have thought that Jupiter was another star that had its own planets? Of course they rapidly shifted position but I might think that the ability to observe the moons of Jupiter without aide may have given insight into planetary arrangement very long before Galileo used his teles...

I've always pictured Cassiopeia as a woman sitting reclined knees bent head back.
To me it seems very obvious but I suspect others see it differently.

I'm curious about the interesting bright object in the upper left of today's image. It seems disconnected from the Tarantula nebula, unlike the various filaments, etc., elsewhere in the image. This is probably just a matter of perception because of it's unique appearance. http://apod.nasa.gov/apod/...

Now I know where Hollywood gets its material.

While the Tarantula Nebula got its name for resembling the legs of the spider I think it’s the face that stars.

The acceleration of gravity isn't determined only by the distance from Earth's center, but by the local density of the crust. As a result, Huascarán Peak in Ecuador, which is slightly closer to Earth's center than Chimborazo, actually has the smallest acceleration of gravity on Earth, 9.7639 m/s 2 ...

If you think of the crew living in a hula hoop 50 feet in diameter circle the Earth 250 miles above Earth's surface (being about 4000 miles from its center) then using 4250 miles as a major radius and 50 ft (0.01 miles) as minor radius the volume of the area http://www.aqua-calc.com/calculate/volume...

I always thought it would be really mean to take apart the cube then put it together with one corner turned, then mix it up and hand it to a genius quick solver, sit back, and enjoy As many really smart people as our world has produced - it makes one think "God" beat us to the punch. :win...

I'm not sure which is more crowded – the space station or the Eastern Seaboard? Ratioing the number of people in the ISS following a corridor all the way around the Earth in one orbit to the number of people in the Northeast Corridor might be a good math problem. :idea: I might bet on the ISS for ro...

What happens when an owl invades a retirement community?
Really - it does.

You all need a place for funny Owls to roost... those prime for a laugh.

"She" sounds more accurate but that wouldn't work either. Definitely not "Shi" even if it is pronounced with a ē. Do you think it's "student" of the eye or "opening" of the eye? Opening fits well.
