The neutron star in the Crab Nebula (M1) is referred to as the Crab Pulsar. Since neutron stars aren't visible to the naked eye, they don't generally get common names.
Only 15 and u grew up with this…Nice
The answer to this question is like the answer to 'how long is a piece of string'? (twice as long as half it's length)
It's all down to a number of factors, the most limiting of which is your budget.
By way of guidance, go for the best known brands, then look at price, and finally, coinsider how much use you will give the item.
Brands to look at in bino's are Swarovski, Pentax, Canon, Nikon.
In cameras there's more choice.
Good shooting!!
Potential energy Pe must be equal to work done W agains the water
Pe=W
since Pe=mgh and W=F d
mgh=F d
We have
h= Fd/mg
h= 1431 x 4.5 / (58.2 x 9.81)
h= 11.3 m
that statement is rather ambiguous; civil, nautical or astronomical twilight?

I'd gladly write papers for cash. The problem is my prices are astronomical. It's highway robbery, if I do say so myself.

You should understand what you prattle off about, it may save you some embarrassment. We can see Black holes indirectly by the X rays that they admit (using satellites like the Chandra X-ray Observatory), or by other means such as Gravitational lensing (proposed and proven by Einstein).As for Venus,yes the surface temperature is very high, as is the surface pressure, because of a runaway greenhouse effect. How do we know that? Because we sent probes there. See ya, kermit.
