A number of astounding astrological phenomena will be visible in 2020. Here's some of what you can look forward to. Accuweather<\/p>\n
Scientists have now seen \"inside\" a planet, a new study said.<\/p>\n
This is the first time that weve discovered an intact exposed core of a gas giant (planet) around a star, study lead author David Armstrong, a physicist at the University of Warwick in the U.K., said in a statement.<\/p>\n
The discovery offers the unique opportunity to peer inside the interior of a planet and learn about its composition, according to the university.<\/p>\n
The star and the planetary core, known as TOI-849b, are some 730 light-years away from Earth. The star is similar to our sun and the core is about the same size as Neptune.<\/p>\n
TOI-849b is an extremely unusual exoplanet in the so-called \"Neptune Desert\" a term used by astronomers for a region close to stars where we rarely see planets of Neptunes mass or larger. An exoplanet is a planet that orbits stars other than our sun.<\/p>\n

So what happened to the gaseous atmosphere that surrounded this planetary core? One theory is that the gas was somehow stripped away, perhaps during a tidal disruption, where the planet is ripped apart from orbiting too close to its star, or even a collision with another planet.<\/p>\n

Another theory is that it never had a gaseous atmosphereat all, which would make it a \"failed gas giant.\" This means that once the core of the gas giant formed, then something could have gone wrong and it never formed an atmosphere.<\/p>\n
The discovery is just the beginning of the research, scientists said:<\/p>\n
Its a first, telling us that planets like this exist and can be found,\" Armstrong said. \"We have the opportunity to look at the core of a planet in a way that we cant do in our own solar system.\"<\/p>\n

\"There are still big open questions about the nature of Jupiters core, for example, so strange and unusual exoplanets like this give us a window into planet formation that we have no other way to explore,\" he said.<\/p>\n
The study was published Wednesday in the peer-reviewed British journal Nature.<\/p>\n
