The James Webb Space Telescope (JWST) has turned its gaze towards a rare celestial object known as ‘The Accident,’ a brown dwarf, which is a failed star, in an attempt to unravel longstanding mysteries surrounding the planets Jupiter and Saturn. The study of this brown dwarf will provide valuable insights into the gas giants’ atmospheric properties and their formation.
Brown dwarfs are celestial bodies that are too large to be classified as planets but too small to sustain hydrogen fusion in their cores, which is the process that powers stars. They are typically the size of Jupiter but can be up to 80 times more massive. They are often described as “failed stars” because they lack the mass needed to trigger nuclear fusion.
The Accident is a unique brown dwarf discovered in 2016. It was named The Accident because it was found unintentionally during a survey of the sky. This brown dwarf is located about 50 light-years away from Earth and is thought to be between 10 to 13 billion years old, making it one of the oldest known brown dwarfs. It is also unique due to its unusually high motion and its extremely cold temperature, which is similar to the temperature of the Earth’s Arctic.
The JWST, a collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA), is the most powerful space telescope ever built. It is capable of observing the universe in the infrared part of the spectrum, which allows it to see through dust clouds and observe cold objects like brown dwarfs.
By studying The Accident, scientists hope to gain insights into the atmospheres of gas giant planets like Jupiter and Saturn. This is because the atmospheres of brown dwarfs are similar to those of gas giants, and the extremely cold temperature of The Accident makes it an ideal object to study to understand the colder parts of gas giants’ atmospheres. This could help answer questions about the atmospheric dynamics and weather patterns on these planets.
Further, studying The Accident could also provide clues about the formation and evolution of gas giants. Since The Accident is believed to be very old, its atmosphere might contain information about the early stages of the solar system.
The JWST’s study of The Accident is part of a larger scientific program called the Webb Guaranteed Time Observations (GTO) program. This program is dedicated to observing a variety of celestial objects, including exoplanets, galaxies, and stars, to answer fundamental questions about the universe. The Accident is one of the first objects to be observed by the JWST under this program.
The JWST is scheduled to launch in 2021. Once operational, it will provide unprecedented views of the universe and is expected to revolutionize our understanding of the cosmos.
