Re: APOD: Lightning over the Volcano of Water (2019 Jul 29)

What does any of this have to do with space? Is there a connection to the science of lightening that relates to planetary exploration? If so, then say so. If not, then post on Instagram or flickr.

Re: APOD: 50 Miles on Pluto (2015 Jul 16)

It is premature to state the surface features of Pluto have an estimated age of 100 million years or so based on the apparent absence of craters. This is our first close observation of an object as far out as Pluto, and the first observation of an object that orbits out-of-plane to the ecliptic. Our...

Re: APOD: Gliese 832c: The Closest Potentially... (2014 Jul

Communicate? We can't even see the thing! How about somebody design a hypothetical telescope that can see exo planets. How about somebody design a hypothetical antenna array that can receive television and radio transmissions coming from an exo planet. For the telescope, use current CCD sensitivitie...

Re: APOD: A Waterspout in Florida (2013 Jul 17)

Nice picture, but what does it have to do with astronomy? Yes, we've seen weather phenomenon on other planets, such as a dust devil on Mars; but, seriously, what is the point of talking about a water spout? Have we actually verified that there is an ocean on a nearby planet or moon? And that it has ...

Re: APOD: A Hole in Mars (2012 Jul 18)

I love it! We need to all check the back of our necks! As far as an scientific analysis that there is more likely to be life in the hole than elsewhere on Mars, consider that life on Earth exists in the most stable environments that have lots of water. Though there is life in giant holes in the Eart...

Re: APOD: Fata Morgana: A Possibly Titanic Mirage (2012 Apr

I live in the California high desert and have seen many mirages. As the text says, it allows an object to be seen from many different angles. That makes an object bigger, not smaller. I've seen city lights about 6 to 8 miles distant expanded to appear as 3, 4 and even 5 lights vertically. I've seen ...

Re: APOD: A Sailing Stone in Death Valley (2012 Feb 22)

Everybody, go to Google Maps, select the satellite view, enter "racetrack playa," and hit return. You'll see that the racetrack is about 2 miles N-S and roughly 1 mile E-W. At the southern end, there is a little point in the shape of the playa. The eastern edge of that point has a half-cir...

Re: APOD: Red Aurora Over Australia (2012 Feb 01)

It is possible that it did glow green, but the sea level observer couldn't see it because of the curvature of the earth. In the summer, I can see thunderstorms a couple hundred miles away, but I only see the tops. In the time lapse video of the aurora, some green can be observed, but it is concentra...
