The Pink Planet That Broke Science 🩷 GJ 504b Challenges Everything We Know | Space Mystery #nasa

[00:00:00]Have you ever seen a pink planet? The surface of this planet called GJ 504b is entirely pink.

[00:00:06]Interestingly, while GJ 504b is about the same size as Jupiter, its mass is four times greater.

[00:00:12]Furthermore, its orbit is nine times farther from its host star GJ 504 than Jupiter is from the Sun.

[00:00:19]This poses a major challenge to our current theories on how gas giants form.

[00:00:23]Previously, scientists believed that gas giants like Jupiter formed at distances from their host stars roughly 50 times the distance from Earth to the Sun.

[00:00:31]Because only at such distances could a small rocky core form, which would then rapidly accrete surrounding gas under strong gravity to form a gas giant. This is the core accretion theory. Some also believe that gas giants accumulate their mass and density through a unique cluster structure, a theory known as disk instability.

[00:00:48]Generally speaking, before the discovery of GJ 504b, scientists' understanding of gas giant formation mostly relied on these two theories.

[00:00:56]The appearance of GJ 504b completely shattered scientists' previous understanding of gas giants.

[00:01:01]And the reason for this might be that GJ 504b is not a planet at all, but potentially a brown dwarf.
