Hank Green explains why there is more chance to simply have […]

Heart Sun’s neutrino heartbeat

The researchers based in Gran Sasso National Laboratory near L’Aquila, Italy, about 1 kilometer into the ground, were able, even in 2007 to detect some of the neutrinos from the Sun, essentially confirming that the theorized fusion reactions, which include the presence of berilium, are correct. Science20 reported at that time about Sun’s neutrino heart […]

The Moon: is has a tail and we would have a catastrophic planet without it

The Moon has a tail made up of sodium atoms very thinly dispersed throughout the small Moon exosphere. Moons atmosphere, called exosphere, is so rare that when it is full Moon and it is between us and the Sun, its atmosphere gets pushed around towards the Earth. This way we will be able to reside […]
