A white dwarf star has actually captured the attention of astronomers, not only because of the intrigue surrounding these firmly wound stars, however also since it appears to have 2 faces. The two-faced white dwarf is known as Janus, a nod to the Roman god of duality and transition. More officially Janus is called ZTF J203349.8 +322901.1, and it was discovered utilizing the Zqicky Transient Facility (ZTF).
While ZTF may have made the initial discovery, the huge, interesting discovery surrounding this star was made later, with the W.M. Keck Observatory in Hawaii, which exposed that the star has a really unusual spectrum-- one side is made up of helium, while the other is a hydrogen-dominant surface area.

This is the very first time that we've discovered a star with 2 various types of surface compositions, too, and the scientists believe we might be taking a look at a star that remains in the procedure of transitioning from one type of surface area to another, developing this unusual impact.
Another belief is that the magnetic fields on the star might be causing the separation. It could be changing the pressure of the world. The next action, though, is to discover more two-faced white dwarf stars like this, and to study them more thorough to see if the very same incidents are occurring there, to hopefully identify exactly why the star is composed the way it is.
In the meantime, at least, we have a lot of other huge observations to follow, consisting of the latest discoveries by the James Webb space telescope, which are entirely altering what we believed we knew about our universe's development.
