Astronomers have been able to peer inside a planet for the first time, according to a new study
They discovered the exposed planetary core that was likely once at the center of a gas giant orbiting a distant star. The core is similar in size to Neptune and was found closely orbiting a star similar to our sun located 730 light-years away. In fact, it's so close to the star that it completes one orbit around it in 18 Earth hours . And the core's surface temperature is 2780.33 degrees Fahrenheit, or 1800 Kelvin. The study published Wednesday in the journal Nature.
Inside outThey found the object was two to three times higher than the mass of Neptune. But it was also very dense, so all of that material created an object the size of Neptune. "We would expect a planet this massive to have accreted large quantities of hydrogen and helium when it formed, growing into something similar to Jupiter," said David Armstrong, lead study author and Ernest Rutherford Fellow at the University of Warwick.
