Explanation: Magnificent island universe NGC 2403 stands within the boundaries of the long-necked constellation Camelopardalis. Some 10 million light-years distant and about 50,000 light-years across, the spiral galaxy also seems to have more than its fair share of giant star forming HII regions, marked by the telltale reddish glow of atomic hydrogen gas. The giant HII regions are energized by clusters of hot, massive stars that explode as bright supernovae at the end of their short and furious lives. A member of the M81 group of galaxies, NGC 2403 closely resembles another galaxy with an abundance of star forming regions that lies within our own local galaxy group, M33 the Triangulum Galaxy. Spiky in appearance, bright stars in this colorful galaxy portrait of NGC 2403 lie in the foreground, within our own Milky Way.

Speaking of space, On twitter Homer Hickam is bitching about NASA testing what we have long known instead of trying to solve the problem and he’s right.
We already know what happens to the body in zero G high radiation environments. NASA sending one of the brothers up for a year will only tell us what we already know. Hickam says the time would be better spent solving the problem rather than confirming what we know.

Cameleopard is Latin for giraffe...............
10,000,000 Light Years. Let’s see.....186,000 miles times 60 times 60 times 24 times 365 times ten million. I’m about six foot, three inches.
Oh, Man, stretch as high as you can, then look at the space you occupy in this universe and fall to your knees in wonder.
There goes my “in before” post.
That’s 9,994,000 more light years than there are years on the calendar!!! ;’)
He’s right insofar as long-duration spaceflight (which includes something as mundane as months of exposure aboard the ISS) will mean longer exposure to higher levels of radiation than are found on Earth, and more need to take cover during solar flares. But the only people going to Mars will be aboard private spacecraft like Elon Musk’s superheavy — assuming they can work out the ass-first landings.

He has no interest in becoming a government employee again but He would make a great advisor for NASA. He’s all for better faster propulsion and habitability and solid decisive steps forward
With a powerful telescope, astrophysicist Scarlett Johansen’s Camelopardis can be seen at the crest of Mulholland Drive this evening.
(Canadian astronomers call it `Mooseknuckleopardis’.)
I noticed he likes nuclear propulsion.
Actually it’s a Giraffe, not a camel.
2403 is one of my favorite objects!
Worth the effort of hunting it down. (GOTO is for sissies)
Yeah, he isn’t afraid of nukes. He calls it irrational fear driven by emotional responses.
He also says NASA needs to get over their fixation with PhDs and listen to the people. Says that your garbage man may not be able to do the math but he might just come up with a better way of shielding against radiation or micro meteor impacts.
