The mesmerizing details of the new Hubble shot

US, WASHINGTON (ORDO NEWS) — Imagine a spiral galaxy. Long spiral arms shifted away from the brightly glowing center, dotted with sparkling star clusters and interspersed with dark streaks of dust

But from our point of view, galaxies can be oriented in any direction, including NGC 5907, also called the “tip of the galaxy”, a magnificent object recently photographed by the Hubble Space Telescope, processed by the scientist Judy Schmidt.

As you can see in the image above, spiral arms cannot be disassembled at this angle. Even most star clusters are hidden by thick galactic dust. However, we can conclude that the galaxy is spiral, because we can still see a bright glow in its center.

This is a galactic bulge: a dense, tightly packed spheroidal group of stars found in the center of most spiral galaxies. We cannot see how it looks from the outside, because, of course, we cannot leave our galaxy, but we can see how it looks from the inside and collect everything else based on our observations of other spiral galaxies.

NGC 5907, located about 50 million light-years away in the northern constellation Draco, is actually a miracle in several other respects. It has a very low metallicity; analyzes show mainly consists of hydrogen and helium. In addition, very few giant stars were discovered in it.

Since heavier elements form during stellar generations forged in supernovae, whose dust is absorbed in subsequent generations of stars, this suggests that NGC 5907 is mostly populated by very old, very long-lived dwarf stars.
