You probably know that our Sun is a star. You also probably know that it is much larger than our own planet, Earth – in fact, you could fit around 1,000,000 Earth’s into the sun! But – do you know which star is largest star we currently know of?
Comet ISON was discovered in September 2012 by Russian astronomers Vitali Nevski and Artyom Novichonok. They are part of a night sky survey program called the International Scientific Optical Network (ISON). The comet was named after this program.

The Red Bull Stratos mission, undertaken on October 14, 2012, went off without any major problems. The mission was an attempt for a balloon assisted aircraft to reach a world record altitude of 120,000 ft and for a human to then perform a freefall skydive from the vehicle at that height. The mission also had the potential for a human breaking the speed barrier during freefall. This was achieved during the freefall descent to Earth.
About 150,000 light years away, a cosmic collision is producing a twisted galaxy with a bright smooth central core. In April of 2001, Hubble’s Wide Field Planetary Camera 2 was trained on a galaxy located in the southern constellation Hydra. This galaxy is known as ESO 510-G13.
