NASA model describes nearby star that resembles early sun

New research led by NASA provides a closer look at a nearby star thought to resemble our young sun. The work allows scientists to better understand what our sun may have been like when it was young, and how it may have shaped ...

A massive protocluster of merging galaxies in the early universe
