He shared this picture on social media saying, “Sometimes you look out the window and it just takes your breath away from how beautiful Earth is. Today is one of those times…#EarthShapes.” Currently, there are 6 people living and working on the space station, conducting important science and research. The orbiting laboratory is located 250 miles above Earth and is traveling at 17,500 miles per hour! At any given time, the station is home to more than 250 experiments, including somet that are helping us determine the effects of microgravity on the human body. Research on the station will not only help us send humans deeper into space than ever before, including to Mars, but also benefits life here on Earth. Credit: NASA

Astronomers took this image as they were observing an extraordinary exploding star – a supernova – near the galaxy’s central yellow core! The star rapidly evolved from a supernova containing very little hydrogen to one that is hydrogen-rich — in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. By studying similar galaxies we hold a scientific mirror up to our own, allowing us to build a better understanding of our galactic environment, which we cannot always observe, and of galactic behavior and evolution as a whole.
