I love science. This is a metal coil outside in 90+ degree heat and its covered in thick rock hard ice with no sign of melting thanks to the liquid nitrogen running through the pipe! #science #chemistry #liquidnitrogen
Scientists have theorized that our Milky Way galaxy has a super massive black hole at the center of it, but how did this idea come about? How do astronomers measure something that has actually never been seen in our telescopes?
Above is an animation of star movements in our galaxy over the past 16 years. They all orbit around a point that emits no light in our galaxy. We can measure the mass of these stars and calculate that their orbits require an object with the mass of 4 million Suns. So far this points to a super massive black hole in our galaxy.

Weather forecasters on exoplanet GJ 1214b would have an easy job. Today’s forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds. A team of scientists led by researchers in the Department of Astronomy and Astrophysics at the University of Chicago report they have definitively characterized the atmosphere of a super-Earth class planet orbiting another star for the first time.
