Faint new planet is revealed around a young star after a decade in hiding Astronomers have uncovered a dim, elusive planet orbiting a young star after more than a decade of observational challenges. The discovery, made by two independent research teams, marks the first time scientists have directly imaged a planet that has remained hidden in data archives for over 11 years. The findings were reported in the Astrophysical Journal Letters, highlighting the planet’s unique characteristics and its significance in understanding planetary formation. The Scottish and German-led team identified the planet, designated as Beta Pictoris b, using the European Southern Observatory’s Very Large Telescope in Chile. They analyzed archival data from the star Beta Pictoris, which is located in the constellation Pictor and approximately 63 light-years from Earth. The planet, which is slightly larger than Jupiter, was previously obscured by its bright host star and two companion planets. Markus Bonse, co-leader of the first team, described the discovery as a “cosmic hide-and-seek” scenario, emphasizing the planet’s long elusiveness. Meanwhile, a California-based team independently detected the planet using NASA’s James Webb Space Telescope. The discovery required only two observations with the powerful instrument, which is the largest and most advanced telescope ever launched into space. Both teams confirmed the planet’s existence independently, ensuring the results were unbiased. The planet’s orbit takes approximately 91 years to complete, slightly longer than the time it takes Uranus to orbit the Sun. The planet’s age, estimated at around 20 million years, places it in a star system that is significantly younger than our own solar system.#james_webb_space_telescope #european_southern_observatory #beta_pictoris_b #beta_pictoris #constellation_pictor
NASA's Webb Discovers Hidden Planet in Famous Star System Astronomers using NASA’s James Webb Space Telescope have made a groundbreaking discovery in one of the most studied planetary systems in the Milky Way. The team identified a massive exoplanet, Beta Pictoris d, hidden within the Beta Pictoris system, a young star located 63 light-years from Earth. This planet, which is at least twice the mass of Jupiter, was detected not by direct imaging but through the unique chemical fingerprint of its atmosphere, marking a significant shift in exoplanet detection methods. The Beta Pictoris system, already known to host two giant planets—Beta Pictoris b and Beta Pictoris c—now has a third confirmed planet. Unlike its counterparts, Beta Pictoris d was not discovered by identifying a bright point of light but by analyzing spectroscopic data. The team used the telescope’s NIRSpec (Near-Infrared Spectrograph) to study the atmosphere of Beta Pictoris b, employing the Integral Field Unit (IFU) to capture both an image and a spectrum from each pixel. This technique revealed a distinctive pattern of carbon monoxide absorption lines, a signature feature of planetary atmospheres. The discovery was unexpected. While the team was focused on understanding Beta Pictoris b, the signal emerged in data where they did not anticipate it. The spectroscopic analysis allowed researchers to determine the planet’s radial velocity, confirming its orbit around the star. The planet’s position, estimated to be about 30 astronomical units from Beta Pictoris, places it in the region occupied by Neptune in our solar system. Despite its wide orbit, Beta Pictoris d lies within the inner edge of the debris disk surrounding the star, a region where planetary interactions are thought to shape the system’s structure.#nasa #james_webb_space_telescope #beta_pictoris_system #beta_pictoris_b #beta_pictoris_c
