Fifty Year Old Moon Mystery Explained
ekarjala writes "This article from NewScientist.com explains that a "flash" on the moon's surface that (captured by an amateur photographer 50 years ago) was probably the result of a 20 meter asteroid hitting the moon's surface."
It's common in astronomy to be able to back to earlier photos and see what was there and what changed since. Much research benefits from this abaility.
Does there not exist someplace a pre-1953 photo of that area of the moon? Ideally several, which could narrow down the time to a window that the "flare" fits.
It'd help make the case. And it'd just be neat to see before & after pictures.
very unlikely. the flash lasted for 8 to 10 seconds :)
