Astronomers have for the first time seen seven baby stars born from a single disk, just like from a batch of dough.
Abstract

Scientists found a system of seven stellar embryos, surrounded by a single disk of gas and dust. This disk, like a carousel spun too fast, breaks into separate clumps—that’s how 'stellar families' with many members are born. Previously, this was only seen in theory. What else do cosmic clouds hide?

In the nebula NGC 6334I, astronomers spotted seven stellar embryos in a single rotating gas and dust disk at distances of 181–461 Earth-Sun distances. This is a record: previously, such disks were known to host no more than two or three.

The disk turned out to be too massive and fast, so it tore apart like thin pizza dough. Each piece condensed into a separate star.

Such a mechanism was considered common for binary systems, but not for seven. Now it’s clear that nature can "bake" a whole family of stars at once.

These tight-knit groups are true factories of cosmic cataclysms. Over time, the stars may collide, explode as supernovae, turn into neutron stars, and merge, emitting gravitational waves. Such mergers forge the heaviest elements, like gold, which we find on Earth.

🎯 Most stars live not alone, but in pairs or trios. But finding seven in one disk is like baking seven buns from one piece of dough. Astronomers saw such a tight neighborhood for the first time.

🎬 Science fiction loves worlds with multiple suns, like Tatooine or Pandora. The discovery shows that nature can light up seven suns at once in one system, bringing the boldest fantasies to life.
