I wasn't intending to post anything on a Sunday night, but I happened on this mind-blowing photograph shot and posted to Twitter by Scott Kelly from the International Space Station.
I'm just catching up on some of the recent spectacular imagery of Pluto sent back by the New Horizons spacecraft during its flyby, and this one really caught my eye.
Although the Reynolds Creek Fire burning in Glacier National Park may not be particularly large (at least not yet), its smoke plume and even its glow have been easily visible from space.
Until today, for all we knew as humans, Earth was the only rocky planet in the universe orbiting a reasonably friendly star within a zone that was neither too close nor too far for life to thrive.
You may think you've seen many images of Earth just like this one since the Apollo astronauts snapped the very first one more than four decades ago.
The first six months of 2015 comprised the warmest first half of any year on record, surpassing the previous global record for January through June set in 2010.
Back in early July, unusual warmth helped trigger a sudden and dramatic spike in melting at the surface of Greenland's ice sheet.
Here they come now — the first incredible detailed images of the surface of Pluto. The image above was just published by NASA, and it shows an absolutely astounding landscape (to my eyes, anyway).
The image above is a screenshot from a stunningly beautiful animation showing Typhoon Nangka swirling in the Pacific.
This past June was the warmest globally in a record stretching back to 1891. That's the verdict from the Japan Meteorological Agency, which issued its latest monthly report on global temperatures today.
After a journey of 10 years and three billion miles, NASA's New Horizons spacecraft has made its closest approach to Pluto.

The El Niño once regarded as "El Wimpo" is getting ever stronger, and it's likely to peak in late fall or early winter as one of the more brawny ones on record.
I was about to write a post focusing on how the current spate of tropical cyclones in the Pacific Ocean could kick El Niño into higher gear when I saw the latest climate report for the United States.
Four cyclones are kicking it up in a kind of meteorological chorus line across the tropical Pacific today.
As brutal heat grips parts of Europe, Asia, North America and South America, another place is also experiencing a spike in temperatures — one that you may not have heard about.
The Sun was very restless late in June. Starting in the third week of the month, it erupted with numerous flares and flung giant clouds of solar material, called coronal mass ejections, or CMEs, toward Earth.
The New Horizons spacecraft has been sending home a steady stream of photos as it has closed in on Pluto.
Pushed by a wildly contorted jet stream, smoke from more than 200 wildfires burning in Canada's Alberta and Saskatchewan provinces has streamed 1,600 miles south, deep into the United States.
I check in at NASA's fabulous Earth Observatory web site almost every day, because I know I'll be treated to spectacular imagery and also learn something new.
