Hubble Space Telescope Observes Conjunction of Two Spiral Galaxies astronomy space science
Otherwise known as IRAS 00226+1236, LEDA 1583 and UGC 241, this spiral galaxy has a diameter of 83,700 light-years.Its elongated neighbor,“Such misleading conjunctions occur frequently in astronomy,” Hubble astronomers said.
“The new observations are from a vast collection of Hubble measurements examining nearby galaxies which contain two fascinating astronomical phenomena: Cepheid variables and cataclysmic supernova explosions,” they added. “Both Cepheids and supernovae have very predictable luminosities, meaning that scientists can tell precisely how bright they are.”
