Have you ever wondered how our Moon evolved over millions of years??
Check out the incredible video about how Moon evolved, all thanks to the Lunar Reconnaissance Orbiter (LRO)!

Statistics say Earth-like planets are rare!!!!
Hopes were high when Kepler was launched to find Earth-like planets, but Kepler’s Statistical Analysis shows Earth-like planets are rare!
Report is presented on Space Daily last week: Check it out here!

Scales of the Universe – New & Improved! MUST SEE! #westernu
Remember the ‘Powers of Ten’ from wayyy back? Well this is updated and interactive with eerie music.
Scroll bar goes from Planck Length to Universe Scale-along with captions.
Einstein vs. Bohr Thought Experiment Round 2
Back in the day, when Quantum Mechanics was just getting started, Einstein suggested a thought experiment that would disprove the Heisenberg Uncertainty Principal, and with that show Quantum Mechanics was inconsistent. Which it could have done if Bohr hadn’t responded in turn with his own thought experiment to win thought experiment round 1 and to keep quantum mechanics alive. Today’s physicists have taken a second look at Einstein’s argument, and say he could have been correct after all. Check this all out here.
Asteroid Threats?
Have the possibility of an asteroid threat coupled with all the 2012 doomsday talk gotten you worried? Check out this article about our possible solutions to those asteroid (Hint: It involves nuclear weapons)
EARTHLINGS DAZZLED BY VENUS-JUPITER CLOSE ENCOUNTER
It seems yesterday night and tonight are fairly special as far as astronomy goes. The two brightest planets Jupiter and Venus will be incredibly close together, and will be easily visible during the night, providing those clouds manage to stay out of our way. Check out the article for some more information.
Line of Sight from Earth to Mars
Here is a cool animation showing the line of sight from Earth to Mars in the Ptolemaic and Copernican models. It’s a pretty cool little animation, so check it out if your interested.
Jokes from the desk of a grad student: Vol 4 #westernu
One day, all of the world’s famous physicists decided to get together for a tea luncheon. Fortunately, the doorman was a grad student, and able to observe some of the guests…
* Everyone gravitated toward Newton, but he just kept moving around at a constant velocity and showed no reaction.
* Einstein thought it was a relatively good time.
* Coulomb got a real charge out of the whole thing.
* Cavendish wasn’t invited, but he had the balls to show up anyway.
* Cauchy, being the only mathematician there, still managed to integrate well with everyone.
* Thompson enjoyed the plum pudding.
* Pauli came late, but was mostly excluded from things, so he split.
* Pascal was under too much pressure to enjoy himself.
* Ohm spent most of the time resisting Ampere’s opinions on current events.
* Hamilton went to the buffet tables exactly once.
* Volt thought the social had a lot of potential.
* Hilbert was pretty spaced out for most of it.
* Heisenberg may or may not have been there.
* The Curies were there and just glowed the whole time.
* van der Waals forced himeself to mingle.
* Wien radiated a colourful personality.
* Millikan dropped his Italian oil dressing.
* de Broglie mostly just stood in the corner and waved.
* Hollerith liked the hole idea.
* Stefan and Boltzman got into some hot debates.
* Everyone was attracted to Tesla’s magnetic personality.
* Compton was a little scatter-brained at times.
* Bohr ate too much and got atomic ache.
* Watt turned out to be a powerful speaker.
* Hertz went back to the buffet table several times a minute.
* Faraday had quite a capacity for food.
* Oppenheimer got bombed.
