Re: APOD: Light at the End of the Road (2016 Sep 01)
It looks like the ecliptic is around 60 degrees off the plane of the Milky Way. How unusual is that, knowing what we do about other 'solar' systems? According to Christopher Springob PhD in a blog named "Ask an Astronomer" at http://curious.astro.cornell.edu/about-us/159-our-solar-system/...

I agree lets fire up the FTL star ship (the government has hidden in aria 51) set a course for a point about one million light years above the galactic core, and get a better picture.

Re: APOD: A Candidate for the Biggest Boom Yet... (2016 Jan 26)
I wonder why the sky of this planet stays so perfectly black. On earth even the light of the full moon masks many stars. Wouldn't a supernova do something similar? Is it just that the featured picture was taken high above the weather? From the POD explanation. The above-featured artist's illustrati...

Re: APOD: Comet Meets Moon and Morning Star (2015 Dec 12)
"New visitor from the Oort cloud." The Oort cloud has millions of these little chappies. So just how does Mother Nature decide which one visits the inner solar system next? I'd really like to know! Could we suddenly get a burst of a few hundred of them? Why not? the short answer is we do ...

I do not believe Kepler can tell us about the orientation of the orbit, because it just see the dip in brightness as a plant orbit the star.Supermoonshadow wrote:Is everything really orbiting in the same direction? The total angular momentum of this chunk of the universe seems to sum to much greater than zero.

I have always lived to far south to see auroral display. It is on my bucket list.

Re: APOD: Centaurus A (2015 Nov 19)
Morning all! My question is regarding the phrase 'active galaxy'. I know that M31 (Andromeda) is the closest galaxy to us, but why is this galaxy considered the closest 'active galaxy'? What makes a galaxy 'active'? (And why is M31 not - or no longer - classified as active?) And this is a beautiful...

What make you thank that ionized hydrogen emitted no light?Guest wrote:There is a mistake in the explanation. There is no light emitted by ionized hydrogen, either it should be neutral hydrogen or other species.
