A NASA satellite suggested what a lunar obscure looks like from Mercury


On a night of Jul 27 and a early morning hours of Jul 28, sky-watchers opposite a Eastern Hemisphere were treated to a longest lunar obscure of a 21st century.

A lunar obscure occurs when a sun, Earth, and moon are directly aligned, and a moon’s circuit brings it into Earth’s shadow. The moon passes by a darkest segment of Earth’s shadow, famous as a umbra, that gives a moon a reddish glaze since of a approach a sun’s light gets refracted by Earth’s atmosphere.

The eventuality perplexed people on Earth, who took overwhelming photos of a “blood moon” — a tenure that comes from a red-orange paint a moon takes on during a lunar eclipse.

German wanderer Alexander Gerst, who is now onboard a International Space Station, even watched and photographed a obscure from his proxy home about 250 miles above Earth .

From other vantage points in a solar system, a obscure would also demeanour remarkable. If someone were station on a moon during a lunar eclipse, a Earth would seem to be surrounded by a bright-red ring of glow .

And NASA’s Messenger satellite, that orbited Mercury between 2011 and 2015, supposing conspicuous footage of what lunar eclipses demeanour like from a solar system’s innermost planet.

NASA satellites orbiting detached planets spasmodic sight their cameras on a moon during these astronomical events, and Messenger did so during a 2014 lunar eclipse. From there, here’s what it looked like:

In this timelapse, that was combined from 31 images taken dual mins apart, a brighter light is Earth, and a smaller one is a moon. Once a moon is entirely in Earth’s shadow, it seems to disappear completely.

Messenger was a initial booster ever to circuit Mercury, though a goal came to an finish when NASA intentionally crashed a satellite into a world in Apr 2015.

If we missed a many new lunar eclipse, we might get another possibility to see one on Jan 20-21, 2019.
