The Atacama Large Millimeter/submillimeter Array (ALMA) has detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new observations allow astronom...
NOAO/Gemini: Sakurai's Object: Stellar evolution in real time
NOAO/Gemini Sakurai's Object Stellar evolution real time
2014/4/16
Stellar lifetimes are measured in billions of years, so changes in their appearance rarely take place on a human timescale. Thus an opportunity to observe a star passing from one stage of life to anot...
