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 […]

Why doesn’t the sun steal the Moon?

Because it is in Earth’s gravitational well or in Earths Hill sphere which goes up to 1.5 million kilometers out in space. From this sphere you can only get away if you break the escape velocity. For earth the escape velocity is about 5 km/s, but where the Mon is it is about 1.2 km/s. […]

Lightning on Earth created by the Sun

Who would ever think that the Sun generates lightnings on Earth? Well, given the fact that we get a lot of energy from the Sun, this should not come as a surprise. DNews reports that cosmic rays and solar wind cause lightnings on Earth. An interesting result from this study: The results could prove useful […]

Tornadoes on the Sun? Your read that right!

Space.com reports that there are tornadoes on the Sun. The Solar Dynamics Observatory has watched the sun on 29th and 30th April 2014 and saw that, instead of the spurs of matter to just go up and away or back as you’d usually see, that highly condensed plasma was behaving like a tornado due to […]

Vsauce: quasars can be brighter than the galaxies they’re in – most brightest thing in the Universe explained

Magnitude is a number that tells you how bright an object is, and it can be relative or absolute. Vsauce explores the Universe of absolute magnitude and finds out that the Sun has a magnitude of 4.83, yet a star called R136a1, 256 times more massive than the Sun, has a magnitude of -12.6 and […]
