Researchers aim to delve deeper into these findings, seeking to untangle the mysteries surrounding brown dwarfs and their complex atmospheres as they continue their groundbreaking analysis.
Meet Wolf Cukier, the 17-year-old who discovered a planet with two Suns just 3 days into his NASA internship
Just three days into his summer internship at NASA’s Goddard Space Flight Center in Maryland, 17-year-old Wolf Cukier discovered a planet orbiting two stars. He picked out a strange signal from a distant star system using data from NASA's Transiting Exoplanet Survey Satellite (TESS) that at first looked like a stellar eclipse. Additional analysis confirmed the presence of TOI 1338 b, a planet roughly 6.9 times the size of Earth and located about 1,300 light-years away in the constellation Pictor. This discovery was the first circumbinary planet found by TESS.
One of astronomy’s oldest suspected planetary systems has just undergone its most sensitive search yet and the biggest planets scientists might have expected to find are not there
Astronomers have conducted one of the most detailed searches yet for planets around 70 Ophiuchi AB, a binary system roughly 16 light-years from Earth. Researchers led by the University of Michigan combined more than a century of observations with modern radial-velocity and astrometric measurements. The study found no statistically convincing evidence of giant planets around either star, while stellar activity explained signals that initially appeared potentially planetary. The findings largely exclude Jupiter-mass planets across much of the inner system but do not rule out smaller worlds.
For the first time in astronomy, scientists detect radio signal from a young planet
Astronomers have discovered notable radio signals originating from the exoplanet Beta Pictoris b, located 64 light-years away from our solar system. These signals hint at an unexpectedly robust magnetic field surrounding the planet. The MeerKAT radio telescope network in South Africa facilitated this groundbreaking observation, revealing fluctuating intensities and timings of the signals related to the planet's rotation, thereby marking a pivotal step forward in exoplanetary magnetic field studies.
Mysterious radio bursts detected 63 light-years from Earth, well beyond our solar system: What scientists discovered about its source
A newly reported radio signature from Beta Pictoris b is giving astronomers a rare way to investigate the magnetic environment of a planet beyond our solar system. Observations with South Africa’s MeerKAT array identified recurring auroral radio bursts at the planet’s location, rather than its host star. The research also provides the first direct measurement of an exoplanet’s magnetic field strength.

Strange radio signals detected from exoplanet almost 63 light-years from Earth
Researchers have observed unusual radio signals from Beta Pictoris b, an exoplanet located 63 light-years away. These signals, detected using the MeerKAT radio telescope, are associated with auroras produced by the planet's magnetic field. The emission identified as electron cyclotron maser radiation indicates a magnetic field strength of approximately 1.25 kG. This discovery marks the first direct localization of auroral radio activity from an exoplanet.
Astronomers just spotted an “Impossible” planet: Elias 2-24 b is the youngest known planet, and its Jupiter-sized growth could challenge planet formation models
Elias 2-24 b is young enough that astronomers are seeing it before its planetary neighborhood has finished taking shape. Yet the planet is already roughly Jupiter-sized. It orbits about 55 times the Earth-Sun distance, far out in a disk where assembling such a massive world should be difficult and slow. That mismatch is what makes the discovery so intriguing: astronomers are not looking at an old planet and guessing how it formed. They may be watching a giant world grow in real time.
A planet 63 light-years away is sending repeating radio bursts, and scientists can read them for the first time. Here’s what it reveals about the alien world
Astronomers detected repeating radio bursts from exoplanet Beta Pictoris b. These emissions originate from powerful auroras on the distant world. The signals provide a rare direct measurement of the planet's magnetic field. Scientists calculated Beta Pictoris b possesses a magnetic field stronger than Earth's. This discovery offers a new method to study exoplanet magnetic environments.
This strange world has no star to orbit, yet James Webb has revealed its changing weather from 20 light-years away
Webb telescope observed SIMP 0136, a brown dwarf twenty light-years away. Researchers found its changing appearance stems from temperature and cloud structure. These two factors explain most atmospheric variability observed by the telescope. The brown dwarf's atmosphere exhibits three recurring weather states as it rotates. This new method helps study distant worlds with limited direct observation.
Astronomers have found a 'baby' planet and named it Elias 2-24 b. The Jupiter-size world is less than 1 million years old
Astronomers have made an exciting discovery with Elias 2-24 b, recognised as the youngest planet identified to date. This gas giant is still enveloped in the material from its formation, indicating it is in a state of growth as it gathers more matter from its surrounding disk. Analysing previous telescope data has allowed scientists to gain valuable insights into the processes behind the formation and evolution of giant planets.
A future without oxygen: Scientists explain what Earth could look like in a billion years - hostile to complex life long before the Sun dies out
Earth's breathable atmosphere is a temporary phenomenon, experts predict. Computer simulations show oxygen loss within one billion years, long before the sun ages. This event will render the planet uninhabitable for oxygen-dependent life forms. Anaerobic organisms, however, will likely continue to survive in oxygen-free environments. This research also impacts the search for alien life on exoplanets.
In 2025, scientists found 'strongest hints yet' of life on Mars and K2-18b—but, a survey of hundreds of astrobiologists say we still haven’t found aliens
Recent scientific findings on K2-18b and Mars sparked alien life speculation. A survey revealed few astrobiologists believed these discoveries confirmed extraterrestrial life. Researchers found the K2-18b exoplanet evidence less convincing than Martian rock features. Many scientists remained neutral, awaiting further analysis and ruling out non-biological explanations. These intriguing clues offer questions for further scientific investigation and testing.
