BERLIN: Baby planet bigger than Jupiter discovered, could shed light on early years of Earth
BERLIN: Astronomers have discovered one of the youngest planets orbiting a star, which could shed new light on the early phases of planetary evolution. Analysis of the planet could help astronomers understand the origin of the solar system and Earth.
Scientists estimate that the planet is a few times more massive than Jupiter and that it formed with its star several million years ago, around the time the main Hawaiian Islands first emerged above the ocean. The discovery has been done by a team of astronomers led by the University of Hawaii at Mnoa faculty, students, and alumni.
The research which was released in pre-print version has been accepted for publication in the Monthly Notices of the Royal Astronomical Society. “This serendipitous discovery adds to an elite list of planets that we can directly observe with our telescopes,” explained lead author Eric Gaidos, a professor in the UH Mnoa Department of Earth Sciences.
AN INFANT PLANET
Astronomers said that the planet is so young that it is still hot from the energy released during its formation, with a temperature similar to the lava erupting from Klauea Volcano. “By analysing the light from this planet we can say something about its composition, and perhaps where and how it formed in a long-vanished disk of gas and dust around its host star,” Eric Gaidos added.
Dubbed 2M0437b, the planet was first seen with the Subaru Telescope on Mauna Kea in 2018 and astronomers have been continuously analysing the planet since. Astronomers used the Keck Observatory’s Near-Infrared Camera in combination with the Keck II telescope’s adaptive optics system to verify that planet 2M0437b was truly a companion to the star and not a more distant object.
“The exquisite data from the Keck Observatory allowed us to confirm that the faint neighbour is moving through space along with its star, and thus a true companion. Eventually, we might even be able to measure its orbital motion around the star,” Dr Adam Kraus, a professor in the Department of Astronomy at the University of Texas at Austin and co-author on the paper said in a statement.
A STELLAR NURSERY
Scientists in a statement said that the planet and its parent star lie in a stellar “nursery” called the Taurus Cloud and it is on a much wider orbit than the planets in the solar system. Its current separation is about 100 times the Earth-Sun distance, making it easier to observe. “Two of the world’s largest telescopes, adaptive optics technology, and Maunakea’s clear skies were all needed to make this discovery,” said co-author Michael Liu.
The star that 2M0437b orbits is too faint to be seen with the unaided eye, but currently from Hawaii, the young planet and other infant stars in the Taurus Cloud are almost directly overhead in the pre-dawn hours, north of the bright star Hokuula (Aldeberan) and east of the Makalii (Pleiades) star cluster.

SAN FRANCISCO: Indian-Origin Founder Unveils Wearable Device That Records Every Moment Of Your Life
SAN FRANCISCO: Advait Paliwal, an Indian-origin entrepreneur, has recently introduced a wearable AI device called Iris, designed to provide users with “infinite memory.” According to Paliwal, the device captures “pictures every minute,” which are stored either on the device or in the cloud, allowing users to preserve life’s small moments and recognize patterns often overlooked.
In a series of tweets, Mr Paliwal, who is based in San Francisco, explained that Iris not only organises the photos into a timeline but also uses AI to generate captions and help users recall forgotten details. Additionally, the device features a “focus mode,” which detects when the wearer is distracted and offers reminders to refocus.
Mr. Paliwal shared that the design of Iris is inspired by the evil eye symbol. He developed the device over the summer at the Augmentation Lab in Cambridge, part of a two-month AI and hardware talent accelerator program. After the program, Mr Paliwal presented Iris to over 250 attendees at the MIT Media Lab, where he received positive feedback, with many expressing interest in owning the device.
Highlighting its potential, Mr Paliwal suggested that Iris could offer safety and health benefits, such as aiding doctors in understanding patients’ daily habits or ensuring workplace safety compliance. In elderly care, the device could help caregivers monitor patients without being intrusive.
However, after Mr Paliwal shared his post on X (formerly Twitter), reactions were mixed. While some users expressed excitement, others raised privacy concerns. One person commented, “It’s an interesting concept, but I wouldn’t want to interact with someone wearing this, taking a photo every minute.” Paliwal responded by pointing out that people are already “constantly taking mental photos.”
Others were more enthusiastic, with one user noting, “I’ve been searching for a device like this for years! A picture every minute should be enough if it archives, organizes, labels, and retrieves them.” Another user praised the concept, saying, “Love the idea. The design and name are perfect. Great work!”

TEXAS: Meet Gopi Thotakura, Indian Who Will Soon Go To The Edge Of Outer Space
TEXAS: In an unprecedented leap towards the stars, pilot Gopichand Thotakura is set to become the first Indian to venture into space as a tourist. Selected as part of the elite crew for Blue Origin’s New Shephard-25 (NS-25) mission, Mr Thotakura will make a journey beyond the Earth’s atmosphere along with five other candidates.
Gopichand Thotakura, an entrepreneur and pilot, joins a distinguished lineup of 31 candidates who have flown beyond the Karman line, the boundary between Earth’s atmosphere and outer space.
A connoisseur of the skies since his youth, Mr Thotakura’s passion for flight saw him defy conventional norms, learning to pilot aircraft before mastering the art of driving. To further his passion, he graduated from Embry-Riddle Aeronautical University with a Bachelor of Science in Aeronautical Science.
Describing him, Blue Origins wrote, “Gopi is a pilot and aviator who learned how to fly before he could drive. Gopi pilots bush, aerobatic, and seaplanes, as well as gliders and hot air balloons, and has served as an international medical jet pilot. A lifelong traveler, his most recent adventure took him to the summit of Mt. Kilimanjaro.”
Born in Vijayawada, the 30-year-old currently runs Preserve Life Corp, a global center for holistic wellness and applied health located near Hartsfield-Jackson Atlanta International Airport
Each member of the NS-25 mission will carry a postcard on behalf of Blue Origin’s foundation, Club for the Future, symbolizing the collective dreams and aspirations of young minds worldwide.
From an environmental standpoint, the NS-25 mission heralds a new era of sustainability in space exploration.
“Nearly 99% of New Shepard’s dry mass is reused, including the booster, capsule, engine, landing gear, and parachutes. New Shepard’s engine is fueled by highly efficient liquid oxygen and hydrogen. During flight, the only byproduct is water vapor with no carbon emissions,” Blue Origins said in their statement.
The launch date for the mission is yet to be announced.
The mission also includes former Air Force Captain Ed Dwight, who was selected by US President John F Kennedy in 1961 as the country’s first Black astronaut candidate but was never granted the opportunity to fly to space.
Blue Origin has carried out six crewed flights — some passengers were paying customers and others were guests — since July 2021, when CEO Jeff Bezos himself took part in the first.
The company is also developing a heavy rocket for commercial purposes called New Glenn, with the maiden flight planned for next year.
This rocket, which measures 98 meters (320 feet) high, is designed to carry payloads of as much as 45 metric tons into low Earth orbit.
