Didn't realize that, but it makes sense now that Sirius Black's animal form is a dog. I wonder if his brother Regulus would become a lion since Regulus is the brightest star in the constellation Leo?

@ander217 regulus means little king/ is the diminutive from rex/reges which means king. The alternative name, alpha leo(nis) obviously does refer to lion. Btw sirius means glowing, but is known as the dog star because it is the brightest star of the canis major constellation. which does mean (great) dog.

Stephen Fry told me that we can't tell whether our galaxy is a spiral galaxy or not.

He does tend to bend the truth to try to trick Alan though.

"Super nova" is a large nova. Nova should also work.
+1
level 66
Jun 28, 2017
Nova is actually a different type of event - the gradual accretion of material onto a white dwarf, for example, can cause a nuclear firestorm - a nova - where all the excess material burns off, and this can happen many times in a recurrent nova system where the white dwarf has a red giant companion it can siphon material off of. There are also type 1A supernovae, which is when in the same sort of system the white dwarf draws of enough mass from its companion to tip itself over the Chandrasekhar limit, or 1.4 solar masses. At this point it collapses further to become a neutron star, releasing a huge amount of energy in the process. For the supernova that most people know, that is a type 2 supernova - death of a high-mass star caused by the fusion of iron in the star's core.

"Explosion of a star" is "nova." It's only a supernova for stars of a certain size. Also you could accept "c" for the speed of light. :)

Nope, Nova is when there is a sudden runaway fusion reaction of hydrogen on a White Dwarf, appearing only in Binary Star Systems. Supernova is the actual explosion of a star, which only happens to Red Giants.

No, nova is a term referring to a phenomenon in a binary star system. It's complicated, but basically one of the stars will become a red giant, leaving behind a white dwarf "core" that is pulled into its orbit. The remaining star will start to shed hydrogen which will eventually fall out of its gravitational pull and onto the dwarf. This will cause the appearance of a "new star." Eventually the dwarf will be pulled into the other star and the nova will end. Been into astrophysics since I was 8.

The nearest star is Proxima Centauri, but it is bound to the Alpha Centauri system as well. That's where that comes from.

Pulsar for neutron star? I'm aware that they're not synonyms, but most pulsars (though some are white dwarfs) are neutron stars.

I tried every color preceding "dwarf" and couldn't get it. I'm sure the answer is right, as I am not expert in astronomy, but I am proud to at least see a comment confirming that I did not completely invent that dwarves are among the densest stars.
