NASA makes beautiful travel posters for exoplanets

Travel posters are so retro, but also so very futuristic when NASA makes some of them, for exoplanets. The freshly released set includes three exoplanets, the Kepler-186f, HD 40307g, and the Kepler-16b. Of the set, Kepler-186f is remarkable because it falls within the habitable zone of its star, which is redder and cooler than our sun. Speaking of cool, the Kepler-16b is located in a binary star system, where you could see two suns in the sky at once, much like Tattooine in Star Wars. Enjoy these posters here, or if you would like one for your room, head on to the NASA website to download (much) higher resolution versions that would be totally awesome as posters.

The Solar System is Flat. This Video Explains Why

We know the solar system is flat, so are several objects in the universe like galaxies, and, as the video points out, Saturn’s rings. So why in the world did our solar system turn out to be flat, with all the three dimensional space available? The video explains it well. This also reminds us of this other video we saw some time ago. It explains similar ideas well enough, although for a two dimensional medium with focus on gravity.

India’s Mars Orbiter Sends Home Its First Image

First image of earth from Indias Mars Orbiter Mission

India’s first mission to Mars, the Mars Orbiter (Mangalyaan) crossed the distance of the moon’s orbit this morning, making it the farthest object sent into space by India. A few days ago, the spacecraft looked back, and sent a postcard back home. This is the first image of Earth taken by the Mars Color Camera (MCC) aboard the Mars Orbiter Spacecraft. The image was taken on November 19, from an altitude of 67975 kilometers.

Uplifting Humanity: Apollo 11 Spacesuit Was Made by a Bra Manufacturer

The suit Neil Armstrong wore when stepping onto the moon was made using cutting edge technology of that time. A good part of that technology and suit construction came from a bra manufacturer in Dover, Delaware. The suit had to live up to a whole range of specifications, a very important one being that it be capable of containing the pressure necessary to support life i.e. 3.75 pounds per square inch of pure oxygen.

Weird Landscapes of Mars

These beautiful images of the irregular and weird landscapes on Mars have been captured by the HiRISE probe. Mounted on the Mars Reconnaissance Orbiter, HiRISE has sent back nearly 30,000 images of our red neighbor, some of them from the expected alien landscapes of a different world. A selection of 150 of these images has been collected into a book titled This is Mars.
