Milky Way Galaxy Has Four Spiral Arms, New StudyConfirmsA 12-year study published in the Monthly Notices of the Royal Astronomical Society has confirmed that our Milky

Way Galaxy has four spiral arms, following years of debate that it has only two arms. Galactic distribution of massive

young stars and compact and ultra-compact H II regions with luminosities greater than 10^4 times that of the Sun. The

map shows the positions of the complexes and individual...
