Revision as of 07:44, 12 January 2012

Each week in 107-02 we will discuss something interesting that has been in the news. The subjects will be drawn from the New York Times, [http://apod.nasa.gov/apod/ Astronomy Picture of the Day], and press releases from NASA, the European Space Agency, the European Southern Observatory, or the Space Telescope Institute. If there is something interesting from one of our telescopes we may tell you about that too. This page has the highlights.


Week of January 9, 2012

The science journal Nature reported the discovery made at the Very Large Telescope of the European Southern Observatory of a cloud of gas that is on a trajectory to fall into the million-solar-mass black hole at the center of the Milky Way.

The discovery was also described in the New York Times with the headline Black Hole Forecast: A Cold Gas Cloud


The center of the Milky Way is a site known as Sagittarius A*, or SgrA* for short. You can watch a short video about this on here:
