home space needs
When provoked, the itsy-bitsy invertebrates known as tardigrades can suspend their metabolism. In that state, they can survive temperatures of... 73 K for days on end, making them hardy enough to endure being stranded on Neptune. So the next time you need space travelers with the right stuff, you might want to choose yeast and tardigrades, and leave your astronauts, cosmonauts, and taikonauts at home.
past origin-of-life events
One of the most significant events in our distant past is still perhaps the greatest mystery: the origins of life itself.
christmas fog blue
Santa knows Physics: Of all colors, Red Light penetrates fog best. That's why Benny the Blue-nosed reindeer never got the gig.
stars moving moon
Perhaps these ancient observatories like Stonehenge perennially impress modern people because modern people have no idea how the Sun, Moon, or stars move. We are too busy watching evening television to care what's going on in the sky.
space people legacy
We should not measure our space-faring era by where footprints have been laid.... We should measure our era by how many people take no notice at all. A legacy rises to become culture only when its elements are so common that they no longer attract comment.
dust birth violent
We still don't know for sure what the trigger was, but since we've discovered meteorites with supernova dust, we do know that a violent explosion rocked our cosmic neighborhood at the time of our birth, and it's quite possible that without it, our stable, stately solar system would never exist at all.
reality names president
I have found that when calculating what no one has calculated before, like my observing sessions on the mountain, my mental acuity peaks. Ironically, these are the times that I would flunk the reality check normally reserved for mental patients and dazed boxers: What is your name? What day is it? Who is the president of the United States?... I do not know, and I do not care. I am at peace with my equations as I connect to the cosmic engines that drive our universe.
nice journey lessons-to-be-learned
What are the lessons to be learned from this journey of the mind through the universe? That humans are emotionally fragile, perennially gullible, hopelessly ignorant masters of an insignificantly small speck in the cosmos. Have a nice day.
oxygen ice breathing
Apart from the obvious advantages of having ice to melt, filter, then drink, you can also break apart the water's hydrogen from its oxygen. Use the hydrogen and some of the oxygen as active ingredients in rocket fuel and keep the rest of the oxygen for breathing. And in your spare time between space missions, you can always go ice skating on the frozen lake created with the extracted water.
stars space clouds
As the plow pushes through a parking lot of light fluffy snow, the snow clumps together in bigger and bigger chunks. Out in space, pressure hitting a gas cloud has a similar effect, except, instead of snowballs, you get stars!
moon years names
All of the full moons for the entire year are special in that they have particular names.
moon cities skylines
In any city with lots of skyscrapers, lots of skyline, the moon seems bigger than it is. It's called the moon illusion.
stars environment havoc
I'm fascinated by the deaths of stars and the havoc they wreak on their environments.
research scientist ifs
If a scientist is not befuddled by what they're looking at, then they're not a research scientist.
