The Earliest Days of NASA

Maria Popova, at Brain Pickings, happened upon a treasure trove of early NASA (and its airplane-only predecessor NACA) archive photos. They are really something. From biplanes to the Mercury capsule, pre-1950 aeronautics seemed to live by the motto of “If we build it, then we can go there.” That’s a sentiment we could use a bit more of.

More here.

New Photo Reveals ‘Ghostly’ Green Nebula in Deep Space

An amazing new photo from a telescope in Chile has captured the most detailed view yet of a green glowing blob 3,300 light-years away from Earth.

The new image, released today (April 10) by the European Southern Observatory, shows the planetary nebula IC 1295 like it has never been seen before. This picture, which ESO scientists dubbed “ghostly,” marks the first time the nebula has been imaged such unprecedented detail.

“It has the unusual feature of being surrounded by multiple shells that make it resemble a microorganism seen under a microscope, with many layers corresponding to the membranes of a cell,” officials from the European Southern Observatory wrote in a statement.

itfeelsfeynman:

An analemma is the figure “8″ loop that results when one observes the position of the sun at the same time during the day over the course of a year. Due to the earth’s tilt about its axis (23.45°) and its elliptical orbit about the sun, the location of the sun is not constant from day to day when observed at the same time on each day over the course of a full year. Furthermore, this loop will be inclined at different angles depending on one’s geographical latitude.

Moon Rise Time Slice…. this is a collage of 11 photos taken over 27 minutes and 59 seconds

Gorgeous. Also photographic proof that the moon is not, in fact, larger near the horizon. That is merely an illusion.

What do they call that illusion? “The Moon Illusion” of course. ASAPScience did a really nice video about it.

Not only that, but see how the moon is red near the horizon? That’s because of the same science that makes the sunsets red and orange! And I did a video about that: “Why is the Sky Any Color At All?”

It all comes together, man! Science!
