NGC 5189

NGC 5189 is a planetary nebula in the constellation Musca. It was discovered by James Dunlop on 1 July 1826, who catalogued it as Δ252. For many years, well into the 1960s, it was thought to be a bright emission nebula. It was Karl Gordon Henize in 1967 who first described NGC 5189 as quasi-planetary based on its spectral emissions

Venus makes Oxygen During the Day

Ok, it's little more than an excuse to show a beautiful image of a fascinating planet, but in a recent scientific study, it was discovered in the upper atmosphere of Venus, during the day (which lasts a little longer than our day, at 243 Earth Days !!) Carbon Dioxide and Carbon Monoxide is broken down by sunlight into it's Carbon and Oxygen. The oxygen then moves around the planet, and over to the night side too, where it plays an important role in the upper atmosphere of the planet.

Amusingly, a full year on Venus is only 225 Earth days, making a day on Venus longer than a year on Venus.

I guess the upshot of this is, every day is your Birthday on Venus, so Happy Venusian Birthday to you all !

Hey. Why isn’t the moon landing a national holiday in the US. Isn’t that fucked up? Does anyone else think that’s absurd?
