New Astronomical facts I've recently found.

Will just list facts that I've got from SKY magazine:

1. Voyager 1, that launched in 1977 reached interstellar space in August 2012.
    I assume that signal from that space ship travels about a year back to earth. That is why we were informed about what was happened last year just recently.

2. Supermassive black hole in the center of our galaxy eats only about 1% of captured particles. Everything else simply escapes powered by burning that 1%.

3. Sunspots are result of disruption in magnetic field created by twists generated by difference in rotation speed between fast Sun equator and slow poles.

4. Methane (CH4) seems to be missing on Mars.Does it mean there is no life that produces the methane or an opposite, there is a life form that eats methane and converts it to something else?
