By conducting Varstrometry for Off-nucleus and Dual sub-Kpc AGN (VODKA), astronomers from the University of Illinois at Urbana-Champaign and elsewhere, have investigated a quasar known as SDSS J0823+2418. The study, published ...
In astronomy, elements other than hydrogen and helium are called metals. While that might make your high-school chemistry teacher cringe, it makes sense for astronomers. The two lightest elements were the first to appear ...
