Every star we see with the naked eye in the night sky is bigger and brighter than the one that’s sustaining life on Earth: our beloved Sun. There are so many stars in the Universe that we cannot count them, physically speaking. The Bible knew it for hundreds of years!

Even nowadays, when astronomers know about the existence of trillions of stars, some of them still catch their attention more than others. The Jerusalem Post tells us about the surprising discovery of a newborn star by scientists from Northwestern University while they were analyzing the magnetic field of a stellar nursery.

Eyes set on the L483 cloud

The astronomers observed the magnetic field of cloud L483 , and found it to be at a 45-degree angle, indicating the presence of a twin star in the interior. Further observations confirmed that the hunch was true. Even afterward, other observations using the ALMA telescope in Chile revealed the existence of a second star in the same region. The two stars represent a binary system.

Erin Cox, who’s the leader of the new research, explained as The Jerusalem Post quotes:

These stars are still young and still forming,

The stellar envelope is what supplies the material to form the stars. It’s similar to rolling a snowball in snow to make it bigger and bigger. The young stars are ‘rolling’ in material to build up mass.

A binary star system represents two stars at once that are ‘dancing’ around one another due to a gravitational bind. In other words, the two stars orbit around each other. When an astronaut finds a binary system, he can kill two birds with one stone, as he finds two stars at once.

The new research was published in arXiv.
