It would look something like this.

A fascinating thing about the Earth is that it does have continents, and they would be visible even without the oceans.

Though the relief in that image is highly exaggerated.

Re: APOD: Charon (2015 Jul 17)

Just to get this straight in my head: If you traced the Moon's (our moon) orbital path around the sun, it would be a wave pattern, getting slightly closer to the sun, and then farther away as it orbits the Earth, then back again, right? Now if the Earth suddenly disappeared, would the Moon continue ...

Hi pianosorplanets, you need look no further than yesterday's topic. A discussion of the economics was had.

Re: APOD: New Horizons (2015 Jun 22)

Chris, since we are using 'place holders' called Dark Matter and Dark Energy for things that we haven't a clue actually are, and seem to be a majority of what makes up the Universe, I cannot share your optimism. I also wouldn't count on not having our current theories to be radically revised once we...

Re: APOD: When Vega is North (2015 May 08)

If one ignores the common use of a planetary foreground for concentric arc star trail pictures, it is a fine, and ingeniously created comparison. If one cannot ignore the admittedly incorrect relationship of the foreground to the 14000 year projected star field arc trails, then it might lead to hype...

Re: APOD: M100: A Grand Design Spiral Galaxy (2015 Feb 11)

I think I get it, Nitpicker. The ring we are seeing is a part of the same surrounding gas cloud we saw when the SN was initially discovered, AND it was hit by the light of the SN at the same time as the dust we saw during the initial nova outburst, BUT because that part of the dust cloud is 4 light ...

Re: APOD: Aurorae over Planet Earth (2012 Oct 11)

This was also a recent Earth Observatory POTD I don't begrudge APOD for using it (other than I follow both sites daily, and this is a repeat for me). It is a fascinating image. I usually prefer color images of aurora. Is the monochrome image due to the filters used? Anyway great picture of our home.

Re: APOD: At the Core of NGC 6752 (2012 Feb 10)

I am so used to seeing fuzzy red blobs in deep space images of galaxies that formed not long after the Big Bang, that I never thought our own galaxy was formed only ~500 million after the creation of the universe. Probably, all galaxies formed in the first billion years or so of the Universe- altho...

What struck me in the description is that NGC 6752 is "Over 10 billion years old". That got me to asking "How old is the Milky Way?" Wikipedia informs it is 13.2 billion years old. http://en.wikipedia.org/wiki/Milky_Way I am so used to seeing fuzzy red blobs in deep space images ...

Re: APOD: Molecular Cloud Barnard 68 (2012 Jan 29)

Whenever I see a picture of a molecular cloud, I am reminded of that Star Trek: TNG episode where Picard and crew are lost in a molecular cloud. A very scary and forbidding place. But now that I see the infrared images, I wonder why Enterprise, the pride of 24th century Star Fleet, couldn't just hav...

Absolutely fantastic APOD and discussion! Thanks you Chris and Ann for your helpful explanations. But this one still confuses me When mass distorts spacetime, it makes it appear (from outside the distorted region) that photons are following a curved path, rather than a straight line (they aren't ......
