This is the only photo ever taken of Concorde flying at Mach 2 (1,350 mph / 2,172 km/h).

Taken by Adrian Meredith from an RAF Tornado fighter jet, which briefly rendezvoused with Concorde over the Irish Sea.

This is what an erupting volcano looks like from space.

@Zekovski Added, thank you! Just a slight change of "magnetosphere" to "atmospheric airglow". https://en.wikipedia.org/wiki/Airglow

@nitpicking If you have questions about these images or about SEM and how its output is processed, I suggest contacting Dr. Todd Simpson at UWO Nanofab, who captured the image. Email: tsimpson@uwo.ca. https://www.uwo.ca/fab/FAQ/People.html

@wonderofscience 150x is well within the range of optical microscopy, and far too low for a scanning electron micrograph. What's the source that says this is EM?

@nitpicking Sourced from the ZEISS Microscopy account on Flickr. I just checked the specs of a few SEM systems online, and 150x is well within their magnification ranges, albeit at the low end. The ZEISS Sigma is 10x - 10,000,000x, and the Hitachi SU8700 is 20x - 2,000,000x.

This is what fine table salt looks like magnified 150 times with an electron microscope.
