Astronomers Discover an Ultra-Massive Grand-Design Spiral Galaxy
Astronomers using the James Webb Space Telescope have discovered Zhulong, the most distant grand-design spiral galaxy identified so far, located at a redshift of approximately 5.2. Phys.Org reports: The galaxy was named Zhulong, after a giant red solar dragon and god in Chinese mythology. [...] Its...
Astronomers using the James Webb Space Telescope have discovered Zhulong, the most distant grand-design spiral galaxy identified so far, located at a redshift of approximately 5.2. The study found that Zhulong has a classical bulge and a large face-on stellar disk with spiral arms extending across 62,000 light years. The study also found that although the disk is still forming stars, Zhulong has a relatively low overall star-formation rate -- at a level of 66 solar masses per year.
