Dying stars that give away their exterior envelopes to make the gorgeous yet mysterious PNe (planetary nebulae) have a latest champion, the inoffensively dubbed PNe “BMP1613-5406.” Huge stars die young and live fast, exploding as strong supernovae only after a few million years.
On the other hand, the huge majority of stars, comprising our own Sun, has much lesser mass and might exist for many billion years before undergoing a short lived but magnificent PNe stage. PNe is created when only a small part of unburnt hydrogen stays in the stellar core. The hot stellar core can shine through after radiation pressure emits much of this substance.
This ionizes the earlier emitted shroud making a PNe and offering a valuable & visible fossil record of the stellar mass loss procedure (PNe having no relation with planets but got this moniker due to their shimmering spheres of ionized gas surrounded by their central hot stars planets).
PNe hypothetically comes from stars in the tune of 1–8 times the Sun’s mass, showing 90% of all stars more huge versus the Sun. On the other hand, till now, PNe have been established to come from stars born with just 1–3 times the Sun’s mass.
Professor Quentin Parker and Miss Fragkou Vasiliki (his PhD student) have now officially smashed this earlier cap and grabbed the evidence that a PNe has come from a star born with 5.5x the Sun’s mass.
On a related note, scientists employing the radio telescope Atacama Large Millimeter/submillimeter Array (ALMA) saw signals of carbon, oxygen, and dust in the early Universe from a galaxy 13 Billion Years back. This is the earliest galaxy where this helpful mixture of 3 signals has been seen. By evaluating the various signals, the group determined that the galaxy is really 2 galaxies combining together, making it the earliest instance of combining galaxies yet found.
