Certain types of supernovae, or exploding stars, are more diverse than previously thought, a University of Arizona-led team of astronomers has discovered. The results, reported in two papers published in the Astrophysical Journal, have implications for big cosmological questions, such as how fast the universe has been expanding since the Big Bang.| AZoQuantum
Astronomers usually have to peer very far into the distance to see back in time, and view the Universe as it was when it was young. This new NASA/ESA Hubble Space Telescope image of galaxy DDO 68, otherwise known as UGC 5340, was thought to offer an exception. This ragged collection of stars and gas clouds looks at first glance like a recently-formed galaxy in our own cosmic neighbourhood. But, is it really as young as it looks?| AZoQuantum
Ahead of the International Day of Women and Girls in Science, AZoQuantum spoke with Jennifer Choy, an assistant professor at the University of Wisconsin-Madison, about the field of quantum physics and her impressive research career in this sector.| AZoQuantum
