We here in the Hoosier State are always happy to look up into the night sky and really appreciate it, especially when something interesting is going on! Indiana night sky events aren't exactly few or far between, and that's probably one of the best things about living here if we're being honest. From stunningly large-looking full moons to magical meteor showers and eclipses, Indiana is home to some of the coolest night-sky events, and this next one is no slouch, either!
You've probably noticed it before, but never had a name for it.
"Earthshine" is a subtle, bluish glow that slightly illuminates the otherwise unlit part of the moon, thanks to the sun's brilliant light bouncing off the surface of Earth being reflected by the moon's surface.
It's visible at different times throughout the year, though the best times to see it are in April and May.
Earthshine is observed during the moon's crescent phase; it gives the moon this beautiful, ethereal kind of presence in the night sky.
It's a great opportunity for aspiring and experienced astrophotographers alike to get out and get some amazing photographs of our moon.
Earthshine was first studied and explained by Leonardo Da Vinci (yes, that Da Vinci!) during the 16th century. Da Vinci was easily one of the most broadly talented men in the history of the earth, and his discoveries have all been invaluable.
This particular discovery is a little more subtle than most, but it's still absolutely fascinating.
Earthshine will be best viewed this spring in about two weeks before the April full moon, so right around March 27th. If you miss it then, that's alright - there will be an encore after the new moon, on April 12th.
It's quite easy to see even with the naked eye, though a good telescope will show you some amazing craters and mountains on the moon's subtly illuminated surface.
It's kind of like having a full moon that isn't as bright as usual; though the moon will be in its crescent phase, the entire Earth-facing surface will be visible.
An actual full moon tends to be so brilliantly bright that it can light up the landscape in even the darkest of areas at night.
It tends to drown out stars and constellations with its vibrancy, but when you've got Earthshine going on, that's not something you need to worry about.
It's a great opportunity to get the whole family outside and observing an awe-inspiring natural phenomenon.
Hoping to witness the Earthshine phenomena this spring in a dark-sky city? Check out the beautiful town of Beverly Shores for a true-dark night sky.
