Without techies and the technology they develop, we wouldn’t be able to do the amazing things we do at NASA, or on Earth and in space. We love our techies! The passionate engineers, researchers and scientists who work on our technology efforts enable us to make a difference in the world around us. They are responsible for developing the pioneering, new technologies and capabilities needed to achieve our current and future missions. 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.

A single, tiny one appeared on Jan. 31, but even that is hard to see in this rotating view from our Solar Dynamics Observatory. The video shows a rotating sun in filtered light for the past week, but it is even hard to tell the sun is rotating since there are just about no features. This spotless period is a prelude to the approaching period of solar minimum next year, when the Sun’s activity will be at the low end of its 11-year cycle. Credit: NASA/SDO
