There's an article in Space.com about auroras on Mars possibly being visible from the surface.
Makes me wonder if Hubble could spot Mars auroras from space?
Hello, The glowing rippling effect you describe sounds like it could be fog illuminated by the light reflected from the object. I suspect that any flappng object would be a bird. There are no real aerodynamic reasons to build an ornathopter. They certainly look cool, but that's about it. :mrgreen: S...
There are a lot of variables in the equation. It depends on you. It depends on the person who loves you. It depends on how you feel about the person who loves you. Without knowing anything specific, I'd say it feels reassuring, knowing that someone (if they love you) will look past your faults and a...
Yipes. That's going to cause some upsets. If I recall correctly, the guy who did the initial Supernova 1A work got the Nobel Prize for it. It will be extremely embarassing if it proves incorrect. Now, I have to wonder about the mechanism for variability. The Type 1A supernova is thought to be caused...
Greetings Folks, Thanks to PBS, I ran across a series of Undergraduate Physics lectures: "The Mechanical Universe" Now, it's been a long time since I sat in a classroom and enjoyed freshman physics, but I find it is a pleasant way to sit back and enjoy the lectures. And the animated diagra...
Heisenberg is driving his friend Schrodinger home from a conference. A cop pulls them over. "DO you know how fast you were going?", asks the cop. "No, but I knew exactly where I was!", said Heisenberg. The cop, suspicious, decides to check the car out. He looks over the cabin, an...
A Higgs Boson walks into a church.
The priest looks at it and tells it to leave immediately.
The Higgs Boson replies "But you need me.
Without me you can't have mass..."
So I'm watching a documentary about the dangers of near earth asteroids crossing Earth's orbit. They've got a program to prepare for any Earth-impactors asteroids by firing missiles armed with Hydrogen bombs to blow them apart before they can cause any damage. They're calling the program Preparation...
A problem I see with this theory is that the universe is demonstrably aging. We can see the progression of the formation of elements in the stars of distant galaxies in the concentration of iron atoms. If the universe is infinitely old, it seems to me there should be a lot more iron than there is. S...
