We all know that at the center of the Milky Way there is a black hole, Sagittarius A*. in 2007 astronomers discovered gas cloud G2 around Sag A*. G2 is observed from the VLT to be falling into Sag A*, this is expected to happen in March. The observations and measurements on G2 has been made in the hydrogen Brackett-gamma and Paschen-alpha recombination lines which have corresponding wavelengths 1875 nm and 103 nm. However, as the G2 starts to be 'gobbled' by Sag A* it will emit x-ray emissions which is best observed by NASA's Swift telescope. This will be the first time we can observe the interaction of the black hole and it's surrounding. It is also cool to see something get sucked into a black hole!

This will be a very interesting event - once in a lifetime! 3 points.
