The First Planet in the Star Cluster

The new planets discovered around a star the size of our sun by astronomers from NASA. The difference is, the star is one of the few stars who gathered close together in a cluster, not a single star like the sun.

The first finding proves that the planet can appear in a dense star. Although the new planet is uninhabitable, star studded sky is a lot more than what we see from Earth.

The two planets discovered by NASA astronomers like Jupiter, the giant gas balls boiling heat because its orbit very close to their parent stars. The two "hot Jupiter" that surround the different star in Beehive Cluster, also known as Praesepe, a collection of 1000 stars that seemed crammed around the core.

Beehive Cluster is an open cluster, or group of stars born at the same time and emerge from a giant cloud of the same material, so that the stars that have a similar chemical composition.
Unlike the majority of star-forming-spread shortly after the young stars are still close to each other due to mutual gravitational attraction.

"We detect more planets that can thrive in extreme environments and diverse as this cluster," said Mario R. Perez, NASA's astrophysics scientist in the origins of solar system program. "Our galaxy has more than 1,000 open clusters like this, which could potentially have a physical condition that can be berths giant planets."

The report, published in the Astrophysical Journal Letters on last week's mention that the two planets in the Beehive cluster named Pr0201b and Pr0211b, according to standard naming conventions planet. "They are the planet 'b' first Beehive," said Sam Quinn, an astronomer at Georgia State University in Atlanta, the principal investigator in this study. *** [SCIENCEDAILY | NASA | KORAN TEMPO 3999]
