What is the significance of the discovery of the exoplanet with a retrograde orbit and a highly inclined axis?

The discovery of an exoplanet with a retrograde orbit and a highly inclined axis is significant because it challenges the current understanding of planet formation. Most planets in our solar system have orbits that are aligned with the Sun's equator, which is also the plane of the solar system. However, this newly discovered exoplanet, called WASP-107b, has an orbit that is tilted 157 degrees with respect to the plane of its host star's rotation.

According to current theories, planets form from a protoplanetary disk of gas and dust that surrounds a young star. The disk is expected to be in the same plane as the star's equator, so any planets that form should also have orbits aligned with the equator. The discovery of WASP-107b suggests that there may be other mechanisms at play that can create planets with unusual orbits.
