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
Astronomers Accidentally Discover Faintest Exoplanet Ever Observed from Earth Astronomers have made a groundbreaking discovery after inadvertently identifying the faintest exoplanet ever observed from Earth. The planet, named Beta Pictoris d, was detected by Ben Sutlieff, a postdoctoral research associate at the University of Edinburgh, while he was studying the atmosphere of an existing exoplanet in the Beta Pictoris star system. The find, which was initially a faint speck in the data, has sparked excitement in the scientific community due to its unprecedented faintness and the implications it holds for planetary formation studies. Sutlieff was using the Very Large Telescope (VLT) in Chile to analyze mid-infrared light from the Beta Pictoris system, focusing on the known planet Beta Pictoris b. During his analysis, he noticed an unusual signal—a tiny speck that appeared in the same region as the existing planets but was far too faint to be immediately recognized as a real planet. “Normally, when you see things like that, you work on the data some more, and these little scrappy signals go away because they're not real; they're noise and they vanish,” Sutlieff explained. However, after sharing the data with Markus Bonse, an astronomer at the European Southern Observatory, the speck persisted even after applying machine learning algorithms to clean the image. The discovery was confirmed by cross-referencing older archival images from the VLT and the James Webb Space Telescope (JWST). These images revealed that the speck had been present for years, detectable through residual heat from its formation, which occurred approximately 20 million years ago.#james_webb_space_telescope #beta_pictoris_d #ben_sutlieff #university_of_edinburgh #very_large_telescope
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

Mysterious Red Dots Observed by James Webb Space Telescope Spark Scientific Debate Scientists are grappling with the enigma of strange red dots detected by the James Webb Space Telescope, which have defied conventional explanations. These celestial features, first spotted in data collected over the past four years, have puzzled researchers due to their unusual characteristics and potential origins. The dots, which appear as faint speckles in the early universe, have sparked a range of theories, from massive stars to black holes, as astronomers attempt to unravel their nature. The red dots were first identified in observations of the early cosmos, specifically within the first two billion years after the Big Bang. Their ubiquity in this era has left scientists uncertain about their identity. Initially, some hypothesized that the dots could represent massive galaxies fueled by supermassive black holes. However, this theory faced challenges, as the dots appeared smaller than expected for typical galaxies and lacked the distinct X-ray emissions usually associated with actively feeding black holes. Jenny Greene, a professor of astrophysical sciences at Princeton University, described the phenomenon as a mystery, noting that it is the first time she has encountered an object whose appearance defies existing understanding. “I think it’s fair to call them a mystery,” she told CNN. In a recent study published in The Astrophysical Journal, researchers Devesh Nandal and Avi Loeb of the Harvard and Smithsonian Center for Astrophysics proposed an alternative explanation: the dots could be supermassive stars. These hypothetical objects, they suggested, might have formed in the early universe from hydrogen and helium, growing to a million times the mass of the sun.#princeton_university #james_webb_space_telescope #harvard_smithsonian_center_for_astrophysics #anna_de_graaff #jorryt_matthee
Webb Telescope Detects Unexpected Atmosphere on Ancient Super Earth Astronomers have discovered compelling evidence that a scorching, molten super Earth once thought to be barren may actually possess a thick, mysterious atmosphere. The findings, published in The Astrophysical Journal Letters, were made using NASA’s James Webb Space Telescope (JWST) and challenge existing assumptions about how such extreme planets retain gas. The planet, designated TOI-561 b, orbits an ancient star at a distance just one fortieth that of Mercury from the Sun, completing a full orbit in just 10.56 hours. Its surface is likely perpetually locked in daylight, with one side permanently scorched by its star’s heat. TOI-561 b has about twice Earth’s mass but differs dramatically in other aspects. Its star, slightly smaller and cooler than the Sun, combined with its extremely close orbit, creates conditions where the planet’s dayside temperature could reach nearly 4,900 degrees Fahrenheit (2,700 degrees Celsius) if it lacked an atmosphere. However, JWST observations revealed a cooler temperature of about 3,200 degrees Fahrenheit (1,800 degrees Celsius), suggesting heat is being redistributed across the planet. This discrepancy points to the presence of a thick atmosphere, which would trap and redistribute thermal energy. The planet’s low density further complicates its characterization. While not classified as a “super-puff” or “cotton candy” planet—terms for exceptionally low-density worlds—its density is lower than expected for a rocky body with an Earth-like composition. Researchers propose that TOI-561 b’s unique structure may involve a smaller iron core and a lighter mantle, possibly due to its formation in a chemically distinct environment.#james_webb_space_telescope #toi561_b #the_astrophysical_journal_letters #university_of_groningen #carnegie_institution_for_science
