Poptren.suara.com – Scientists have found an object that is the hottest in the entire universe. This object is not sun or a planet, but has a much higher temperature than the sun, although its light is not as bright as the sun. This mysterious object is a brown star.
This brown star emits heat that exceeds the heat emitted by the sun. Located about 1,400 light years from Earth, this object is named WD0032-317B. The discovery was made by a team of scientists led by astrophysicist Na’ama Hallakoun of the Weizmann Institute of Science in Israel.
This brown star has a very close orbit to its host star, which keeps its temperature above 8,000 Kelvin (about 7,727 degrees Celsius or 13,940 degrees Fahrenheit). This temperature is referred to as “so hot that it can break the molecules in the atmosphere into their constituent atoms.” For comparison, the sun’s temperature is about 5,778 Kelvin.
Previously, NASA, the United States space agency, had described brown stars as small, low-mass stars that “failed” and became “a lost link between gas giant planets.”

Brown stars are often difficult to observe because of their light and low energy, and were virtually undetectable until the late 1980s.
What makes these objects even more interesting is that while brown stars are generally hotter than planets, scientists say they are usually cooler than the coldest red dwarfs, because they can’t reach the very hot temperatures that red dwarfs can.
In addition to this exciting discovery about this object, the team of astronomers also believes that the discovery of this brown star could provide a better understanding of the planet Jupiter, as well as other gas planets orbiting hot, massive stars, which are difficult to study in isolation due to their activity and fast rotation. the star.
