Starship Asterisk*

The 600 solar masses is the amount of mass contained in the expanding shell from both the material ejected from the nova and the other nebula gasses that were displaced from the shock wave. Dark matter isn't an issue here.

There is one thing known to escape a Black Hole - Gravity. Ideas to ponder: If gravity is a attractive force pulling one gravity field to another, why doesn't gravity pull it's field back on itself? What is the speed of gravity, is it instantaineous or the same as the speed of light? no no, if you ...

One way to measure the speed of gravity would be to have a mass traveling near the speed of light and measure it's effect as it passes close to a stationary object.

With out knowing the star's size, the rotational speed, or the eccentricity of the orbit, that's the best I can estimate. The chance of that star still orbiting in 10 thousand years is next to none, a .01% derogation in its orbit increasing exponentially on a six months orbit should give it a few hu...

Sorry, I can't pick one -its like trying to pick your favorite child. So many of these picts are History-in-the-Making. Never before has the public had such fast access to new discoveries.

The star 17 light-minutes from the black hole is most likely in a decaying orbit, tidal shifts in the star caused by the eminence gravity field of the BH stretching it out of shape causes it to slow down, as it slows it falls closer to the BH. I would estimate that the star will be torn apart and it...

Here's a couple easy-read sites to add to your info base.

Remember, it is only a theory that a neutron star is composed of only neutrons, we could all be wrong and it might be another state of matter or a mix of different matter-states all together.

Sorry, I like thinking outside the box - that's where the action is!

Sounds like you could use a career change, life and work is wonderful when you follow your passions.

My favorite flooding picts. http://antwrp.gsfc.nasa.gov/apod/ap050228.html http://antwrp.gsfc.nasa.gov/apod/ap050720.html http://antwrp.gsfc.nasa.gov/apod/ap010629.html Evidence points to volcanic and impact heating to be the cause most of the flooding on Mars. It is most likely that the flooding ha...

That's a wonderful and closely related question about the state of matter in the core of a neutron star, it has me thinking on a new tangent. Recent developments of grand unification models have suggested that a neutron in a nucleus might decay with a half-life of 10^32 years, but a free neutron has...

Your questions aren't easy to answer, a newly formed neutron star has a temp that can run in the millions degrees C, but that could be related to near by gasses being drawn in or the radiation given off as a remaining atmosphere collapses. I haven't seen any research that would venture to put a valu...

From what I understand about neutron stars, the artist's concept could be a fair representation. They can vary is size and they start hot and cool over time. If they had any type of atmosphere it would be a very thin, dense layer and be extremely hot giving off high-energy radiation ionizing any sur...

Wait, let me get my camera first and I'll meet you at the sumit.

All that is needed is a Sun with one heck of a heliosphere.

If I'm looking in the right place at what I think you're seeing in the area in question, are columns of dark nebula gas and dirt moving slower and congealing behind objects that are shielding the nebula “stuff” from the high-energy stellar winds. Sort of like a shadow but also contains cooler, more ...

I would try a different constellation and anticipate where the next pyramids might have been built. Or maybe . . . One Of The Pyramids Is Missing!!!!!

The heavy elements are mixed throughout the planetary nebula, as a solar system forms, the star ignites and the proto planets form. Most of the heavy elements in the proto star are heated and crushed by the proto star's gravity becoming part of the plasma at the core. As the planets form, the lighte...

Just wanted to show where these larger element may be formed. Doesn't light spectrum show what a stars composition may be? Orin The core of most stars are plasma and nearly all the rest is H and He and contain a very small % of the heavy elements, or at least not until some of their last dieing bre...

A number of objects could be placed randomly anywhere and one could find at least one set of star patterns to match.

I think you would need to bring your high energy, gamma ray deflection pajamas also, near the center of the galaxy is a much more hostile environment. In another 5 to 10 years the Voyagers should be able to tell us what the sun's heliosphere is protecting our solar system from, (high-energy nebula w...

Cool! - Thanks -

Visual aid to colliding stars.

Careful now, some of your "WOWs" of science maybe stuff yawns are made of for others. Look, learn, move on. The APOD isn't any one persons personal slide show.

I find it fascinating such complex technology actually works yet it is one step above being drug cross-field by a team of donkeys.
