GOES-16: Moon over Planet Earth
Explanation: Launched last November 19 from Cape Canaveral Air Force Station, the satellite now known as
GOES-16 can now observe planet Earth from a
geostationary orbit 22,300 miles above the equator. Its Advanced Baseline Imager captured this contrasting view of Earth and a gibbous Moon on January 15. The stark and airless Moon is not really the focus of GOES-16, though. Capable of providing a high resolution full disk image of Earth every 15 minutes in 16 spectral channels, the new generation satellite's instrumentation is geared to provide sharper, more detailed
views of Earth's dynamic weather systems and enable more accurate weather forecasting. Like previous GOES weather satellites, GOES-16 will use the moon over our fair planet as a calibration target.

Nice photo!
It brings out both the brightness and the color contrast between the Earth and the Moon very well. At least, I don't think the Moon has been artificially brightened here, but I didn't check to make sure...

Great example of the reddish tint of the moon (warm toned, not cool toned). It looks like the Earth has an edge mask applied; I would have expected to see a fuzzy limb of our planet.

Very nice photo. While the moon looks more or less the same as many other photos from Earth the background makes this image unique. I wrote a post with a
collection of Earth from Space photos, and while this is from near space, I added it.

This may sound like a joke but it really isnt:
Soon these pictures will be kept from the public domain because they show weather and will be 'audited' by Trump.

Gee, that looks like the Olympic Peninsula and Vancouver Island, and Washington and Oregon States....Which is where I live...
Awesome image...

I agree with chadair, there is something wrong with Earth's limb. In an image with such good resolution and dynamic range, the Earth's limb (horizon) should look more realistic than that. The foreshortening of clouds near the apparent limb also suggests it has been masked or cut off. MIght lead some to suspect the reality of the whole thing.

The weather does look bad.

Wow, that is a fascinating image.
It took me a while though to find that GOES stands for Geostationary Operational Environmental Satellites. I also found that GOES-16 was originally called GOES-R but once a GOES satellite is in geostationary orbit it is then given a number.

One is looking pretty far North into the Polar Night of January 15.
They tried to adjust for the fading light as best they could but at some point they simply gave up and put in a mask.
It's a PR 'photo' not a scientific one.

I fear for the scientists in the future U.S. ...

GOES-16 and GOES-13 Earth Photo Comparison from Jan 15, 2017.
With five-times greater coverage, four-times the spatial resolution, and three-times the spectral channels than earlier generations of GOES-16's Advanced Baseline Imager can provide more detailed imagery and multi-task in ways that previous GOES imagers could not. For proof of that, consider the following image comparing full-disk images captured by two NOAA satellites -- GOES-16 and GOES-13 -- at the same time on the same day: 1:07 p.m. EST on January 15, 2017.
On the left is a color-composite full-disk image from NOAA's newest geostationary weather satellite GOES-16 (located at 89.5 degrees West longitude), which was created by combining data from the ABI's 16 spectral channels. By comparison, the imager aboard GOES-13 has just five spectral channels, and their data cannot be combined to produce color composites with this "true color" effect without the inclusion of additional data sets.
In addition to offering more channels, the ABI can provide a full disk image of the Earth every 15 minutes, one of the continental U.S. every five minutes, and has the ability to target regional areas where severe weather, hurricanes, wildfires, volcanic eruptions or other high-impact environmental phenomena are occurring as often as every 30 seconds.

I'll take the newer model then!
