The Long Gas Tail of Spiral Galaxy D100 : Why is there long red streak attached to this galaxy? The streak is made mostly of glowing hydrogen that has been systematically stripped away as the galaxy moved through the ambient hot gas in a cluster of galaxies. Specifically, the galaxy is spiral galaxy D100, and cluster is the Coma Cluster of galaxies. The red path connects to the center of D100 because the outer gas, gravitationally held less strongly, has already been stripped away by ram pressure. The extended gas tail is about 200,000 light-years long, contains about 400,000 times the mass of our Sun, and stars are forming within it. Galaxy D99, visible to D100’s lower left, appears red because it glows primarily from the light of old red stars – young blue stars can no longer form because D99 has been stripped of its star-forming gas. The featured false-color picture is a digitally enhanced composite of images from Earth-orbiting Hubble and the ground-based Subaru telescope. Studying remarkable systems like this bolsters our understanding of how galaxies evolve in clusters. via NASA

Ah yes, an Apollo CSM can hold five people

Space is one of the most hazardous environments for a human being to exist in. That's what makes it so damned enticing.

Space is so essentially deadly. It differs from any location on Earth in that way. You can't 'tame' space. You can't make a vacuum hospitable. Space is a desolate, dry, sterile, irradiated expanse, which is home to extreme temperatures and occasional overspeeding projectiles, and to which full-body exposure is almost instantly lethal. Space must command your respect.

I wish some people would realise that the obstacle to colonising Mars isn't just a lack of funding. It's crazy that there's people in the world who think that billionaires are just going to build extraterrestrial cities like it's so easy. ‘Oh, we'll just build thousands of giant rockets, and oh we'll just stuff 100 people inside each, and oh we'll just travel in an armada through deep-space, and oh we'll just land thousands of giant rockets on Mars, and oh we'll just build a city with millions of inhabitants on a freezing rocky desert with no breathable atmosphere, almost no running water, toxic soil, literally nothing to eat, and no economic incentive. Why hasn't anyone done this already? Total no-brainer!’

I say this because I used to be the kind of person who had actually thought that Mars colonisation were possible and could happen in my lifetime.
