SANTIAGO : NASA Webb Space Telescope Target: Possibly the Youngest Exoplanet Ever Found
SANTIAGO : Astronomers said Tuesday that the world’s largest radio telescope, the Atacama Large Millimeter/submillimeter Array in Chile, might’ve picked up a signal from the youngest exoplanet discovered to date.
It’s a nascent world thought to have a Jupiter-like mass and to orbit the adolescent star AS 209, a supposed 1.6-million-year-old ball of gas that floats roughly 395 light-years from Earth in the constellation Ophiuchus. Translating from Greek to “serpent-bearer,” this regal title was given to the cosmic dot-to-dot because of the constellation’s resemblance to a man grasping a snake.
However, as the discovery team notes in its study on the find published in The Astrophysical Journal Letters, we aren’t yet 100% sure that this baby exoplanet really exists. And even if it does, we don’t quite know that it’s the youngest of its kind. There’s some margin for error on that front, so further investigation is required — an endeavor made difficult because the exoplanet candidate also appears shrouded in a halo of gas and dust.
Fascinatingly, that “circumplanetary disk” is the main reason scientists believe an exoplanet is sitting near AS 209. These rings are hypothesized to give rise to moons and help develop infant planets as they flourish into strong bodies — though in truth, the Chilean array of 66 high-altitude antennas might’ve merely detected random blobs of matter rather than a full-on orb inside the disk.
But you know what we now have to clear some of this up? Something that can delve into the distant, difficult-to-study universe and pierce through veils of thick gas and dust? Yep, NASA’s James Webb Space Telescope infrared superhero strikes again.

In the near future, the study team intends to call on the JWST’s infrared parsing ability to, first of all, confirm whether AS 209 really is 1.6 million years old. Then, the ‘scope might be able to discern whether a planet is legitimately present inside the dusty halo — if it is, the JWST could potentially use infrared spectroscopy to give us a really clear picture of what it’d be like to stand on it.
Unlike regular images, spectral datasets offer information about chemical composition, atmospheric cloud content and other such qualities that can’t be captured with an aesthetic snapshot.
“The best way to study planet formation is to observe planets while they’re forming. We are living in a very exciting time when this happens thanks to powerful telescopes, such as ALMA and JWST,” Jaehan Bae, a professor of astronomy at the University of Florida and lead author of the paper, said in a press release.

Science images from the research show (right) bloblike emissions of light coming from otherwise empty gaps in the highly structured, seven-ring disk around AS 209 (left). This indicates possible presence of an exoplanet.
If Bae and fellow scientists are correct that there’s a super young (old?) exoplanet hovering around AS 209, it could be a huge development for the field of astronomy and add to the exciting ledger of JWST revelations.
That’s because, beyond its extraordinary youth, this candidate exoplanet seems to be an anomaly among the 5,000 or so identified thus far. Its signal to ALMA is rooted more than 18.59 billion miles away from its host star, which the team says challenges currently accepted theories of planet formation. For context, Earth is only about 93 million miles from the sun.
Further, it’s fortuitous that this potential world is enveloped in a circumplanetary disk, and notably one that has gas present within.
It wasn’t until 2019 that ALMA scientists made the first-ever detection of this phenomenon, while observing another young exoplanet, called PDS 70c. According to a paper published last year, that halo was probably constructing a moon for the beige gas giant. But since then, experts haven’t found many more.
“Fundamental properties of CPDs, such as their sizes and whether they are indeed rotationally supported ‘disks’ or instead pressure-supported envelopes are not fully understood,” the study authors write.
But having that knowledge could help us extrapolate ancient dynamics of planets in our solar system, including Earth, as well as teach us how moons like our own glowing companion once formed long, long ago. Decoding the interplay between this disk and exoplanets could shed light on how and why planetary atmospheres and general environments form.
For now, hopes are high about the potential burgeoning world tucked into the serpent-bearer’s grip. The study authors optimistically write that the most likely explanation for ALMA’s results so far is that we’re witnessing a planet and its CPD embedded in the region around AS 209.

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.
