There are more than 3,900 confirmed planets beyond our solar system. Most of them have been detected because of their "transits" -- instances when a planet crosses its star, momentarily blocking its light.

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. Even though it is a small, or so-called dwarf galaxy, the SMC is so bright that it is visible to the unaided eye from the Southern Hemisphere and near the equator. Many navigators, including Ferdinand Magellan who lends his name to the SMC, used it to help find their way across the oceans.

Stars are born in hiding, when dense regions within clouds of gas and dust collapse under their own gravity. But the clouds not only provide the raw material for star formation, they also absorb most of the light from their interior, hiding from view the crucial details of stellar birth -- one of the key astronomical processes if we want to understand our own origins!

The Virtual Observatory and its Benefits for Amateur Astronomers

"The contemporary astronomical instruments have been producing the unprecedented amount of data. The largest part of this "data avalanche" is being produced by deep all-sky surveys yielding terabytes of raw data per night. Such a great data volumes can hardly even been reduced by automatic pipelines running on supercomputer grids but it is impossible to exploit fully their content by a small group of professional astronomers in the interested research teams. New tools for collaborative work with heterogeneous data sets spread over distant servers are being developed in the framework of the Virtual Observatory (VO)."
