Rare Jupiter-Sized Planet Discovered Using Phenomenon First Predicted by Einstein
Scientists from Vilnius University (VU) Faculty of Physics, along with members from Poland and other countries, discovered a rare planet using a space-time phenomenon first predicted by Albert Einstein. The planet AT2021uey b is a Jupiter-sized exoplanet located approximately 3,200 light-years away from Earth in the galactic bulge.
The planet was discovered using gravitational microlensing, a method based on Albert Einstein's theory of general relativity that detects planets by measuring the bending and magnification of light from a distant star as a massive object passes in front of it.
AT2021uey b orbits a small and dim M dwarf star. It completes its orbit every 4,170 days, which is roughly equivalent to 11 years on Earth. Live Science reported that AT2021uey b's shadow was first spotted in 2021 when scientists analysed data taken by the European Space Agency's Gaia telescope.
The discovery of AT2021uey b, which is on the far edge of our galaxy, challenges traditional models of planetary formation, suggesting that gas giants can form in regions of the galaxy previously thought to be inhospitable.
The findings, published in Astronomy & Astrophysics, open up new possibilities for understanding planetary formation and the potential for life in diverse environments throughout the universe.
"This kind of work requires a lot of expertise, patience, and, frankly, a bit of luck. You have to wait for a long time for the source star and the lensing object to align and then check an enormous amount of data. Ninety percent of observed stars pulsate for various other reasons, and only a minority of cases show the microlensing effect," Dr Marius Maskoliunas, the head of the Lithuanian research team, said as quoted by Phys.org.
"What fascinates me about this method is that it can detect those invisible bodies. Imagine a bird flying past you. You don't see the bird itself and don't know what color it is - only its shadow," the statement added.
"But from it, you can, with some level of probability, determine whether it was a sparrow or a swan and at what distance from us. It's an incredibly intriguing process," Maskoliunas explained.

James Webb captures first direct image of an exoplanet; key details inside
credit: In a groundbreaking moment for space exploration and technology, astronomers have captured the first-ever direct image of an exoplanet using the mighty James Webb Space Telescope. This is a significant achievement that marks a major leap in the ability of the world to study worlds beyond our solar system. There exists a more fascinating world, all waiting to be explored by us! The JWST has identified a faint source of infrared light in a disk of debris surrounding a young star, called TWA-7, approximately 34 light-years away from Earth. Their intelligent observations reveal that this planet is 10 times less massive than previous exoplanets to be directly observed with a telescope; the first was discovered back in 1992. But are we sure it is an exoplanet? What is the James Webb Space Telescope? Credit: canva JWST is one of NASA 's most powerful and advanced telescopes, launched back in December 2021. It doesn't orbit the Earth like other telescopes, but it orbits the Sun 1 million miles away from the Earth at what is called the L2 or second Lagrange point. Dr. Anne-Marie Lagrange, an astrophysicist at the French National Center for Scientific Research in Paris, quotes, 'The basic problem is that the star is bright and the planet seems to be a little faint.' Usually, the starlight outwits the planets, making them impossible to spot. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Adidas Three Shorts With 60% Discount, Limited Stock Available Original Adidas Shop Now Undo Dr. Anne, with all her colleagues, decided to focus on young stars that could be easily seen on the pole-on. The potential planet orbits roughly 50-52 times farther from its star than Earth is from the sun, and has a mass about one-third that of Jupiter's. Simulations of such an exoplanet in a dusty disk around a star produced images closely matching those from JWST. 'This was really why we were confident that there was a planet,' Lagrange says. What comes next? So, the team behind this magnificent discovery thinks that the JWST could soon be able to spot planets with just 10% of the mass of Jupiter, getting close to the size of Neptune. This groundbreaking discovery also gives scientists a roadmap for further space explorations and establishes ground-based telescopes that might detect even smaller and more Earth-like planets.

From Einstein to Newton, how did world-famous scientists crack the genius code? Here is what their unique learning habits teach students
Albert Einstein, the man who revolutionised our understanding of space and time, regularly skipped university lectures. Marie Curie, the first woman to win a Nobel Prize, often collapsed from hunger whilst studying late into the night in a freezing Parisian garret. Isaac Newton made his most groundbreaking discoveries not in the hallowed halls of Cambridge, but locked away in isolation during a deadly plague outbreak. These aren't tales of academic rebellion or hardship, they're glimpses into the unconventional study methods that shaped history's greatest minds. While most of us were taught to sit quietly in rows, take meticulous notes, and memorise facts for exams, the world's most brilliant scientists were breaking every rule in the educational handbook. What if everything we've been told about effective learning is wrong? What if the secret to genius isn't natural talent, photographic memory, or even prestigious education, but rather a fundamentally different approach to how we absorb and process knowledge? The study habits of history's most brilliant minds reveal fascinating patterns that challenge everything we think we know about effective learning. Here are unique study habits of some of the world's greatest minds. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Brass Idols - Handmade Brass Statues for Home & Gifting Luxeartisanship Buy Now Undo Albert Einstein Albert Einstein's academic journey defies conventional wisdom. At thirteen, he taught himself an entire year's worth of mathematics, not because he was forced to, but because his curiosity demanded it. Einstein found traditional classroom environments stifling, particularly those focused on rote memorisation. Even at university, he skipped lectures regularly, preferring to rely on classmates' notes whilst dedicating extensive time to studying theoretical physics independently. This wasn't laziness, it was strategic brilliance. Einstein understood that true learning happens when we take ownership of our education, following our curiosity rather than rigid curricula. Issac Newton Isaac Newton's most productive period came during 1665-1666, when a plague outbreak forced him to leave Cambridge. In isolation, he made groundbreaking discoveries that would revolutionise science. Newton combined deep theoretical reasoning with meticulous experimentation, building his own instruments and refining his methods over years. Similar to Einstein, he described himself as a "lone traveller" who valued solitude as essential to his intellectual process. This pattern suggests that genius often requires stepping away from the noise of conventional academic environments to think deeply and independently. Richard Feyman Richard Feynman revolutionised learning with his deceptively simple approach. He maintained a "Notebook of Things I Don't Know About," actively identifying knowledge gaps rather than avoiding them. His method involved breaking down complex topics, reassembling them from first principles, and ensuring he could explain everything simply. This technique; now known as the Feynman Method, forces learners to confront their limitations honestly. If you can't explain something in simple terms, you don't truly understand it. Marie Curie Marie Curie's approach to study was defined by extraordinary perseverance against overwhelming odds. Raised in Russian-occupied Poland, she pursued education through underground schools where forbidden subjects were secretly taught. At the Sorbonne, she endured extreme poverty, studying late into the night and often collapsing from hunger. Curie's method was rigorous and patient; she spent years extracting tiny amounts of radium under dangerous conditions, driven by pure scientific curiosity rather than recognition. Her meticulous experimentation reflected her belief that science was a mission, not a performance. APJ Abdul Kalam Dr APJ Abdul Kalam's educational journey demonstrates the power of practical learning. From his early days in Rameswaram to his specialisation in aeronautical engineering, he consistently pursued education with determination despite financial challenges. His approach was notably hands-on, he didn't just absorb theoretical knowledge but applied it directly to real-world aerospace and defence challenges. Throughout his career, Kalam embraced continuous learning and innovation, understanding that true mastery comes from bridging theory and practice. Rosalind Franklin Rosalind Franklin studied with remarkable precision and independence, choosing science as her path at just sixteen. Her mastery of X-ray crystallography was exceptional, and she used this technique with extraordinary skill to investigate atomic structures. Often working in isolation due to institutional sexism, she upheld the highest standards of scientific inquiry, meticulously controlling experimental conditions and performing complex mathematical analyses. Franklin's unwavering commitment to clarity and scientific truth, even in the face of discrimination, demonstrates that excellence transcends social barriers. Where do all their strategies meet? Several patterns emerge from examining these extraordinary minds: Independence over conformity : Each genius preferred self-directed learning over traditional educational structures. They followed their curiosity rather than prescribed curricula. Depth over breadth : Rather than superficial coverage of many topics, they pursued deep understanding of fundamental principles. Isolation as a tool : Solitude wasn't loneliness, it was a deliberate strategy for deep thinking and focus. Practical application : They didn't just learn theory; they applied knowledge to solve real problems. Embracing difficulty : Instead of avoiding challenging topics, they actively sought out what they didn't understand. Is your child ready for the careers of tomorrow?
