It's not a spiral galaxy? A barred spiral sounds like a type of spiral to me!

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.

That's true. We can't see what our galaxy really looks like because we're IN our galaxy.

It's inaccurate to say we can't figure out the shape of our galaxy. Of course we can't see it from the outside but by knowing the distances and positions of stars we can map it out.

^ We may have mapped it accurately by now as I was going on an episode from QI from several years ago.

I'm still not completely convinced that we do know though - it's a bit like saying that you can tell the shape of a forest that you are standing in by knowing the distance and direction to each tree. It's true, but it's a very slow process collecting the data

"Super nova" is a large nova. Nova should also work.

Level 70
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.

There are also type 1a supernovae - collapse of a white dwarf to a neutron star

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.

Then you might just as well ask to accept HR2491, HD48915 and HIP32349. Or you could just type Sirius because you know that's it's name.

Good quiz! Could inflation be accepted for the cosmic expansion one? Of course Big Bang is an acceptable answer but the huge expansion you see when you look at a timeline of the universe in today's models and which you were probsbly referring to) is actually the inflation. It occurred 10^-30s after the Big Bang which is t=0. And I kind of second the suggestion to accept c for speed of light though it's a boring 1-letter answer, as it is a fundamental constant which would exist even in a world without light, and actually everything (light, the Earth, your dog...) move at that speed in spacetime. The question is, when u set a reference frame, how much is converted into time movement and how much goes to space movement. But speed of light (in vacuum) is correct too. These are just suggestions. I like this quiz as it is now too.
