James Webb Space Telescope discovers its first exoplanet as stunning image is revealed
This discovery is out of this world. For the first time since its operations began in 2021, the James Webb Space Telescope (JWST) has captured a direct image, published by the journal Nature, of a new exoplanet — a planet that orbits outside the solar system. This discovery marks a major breakthrough in astronomy and a 'new step' in the ongoing search for planets that exist beyond our solar system. This discovery was made possible by a team from France's National Centre for Scientific Research (CNRS), working at the Observatoire de Paris-PSL in partnership with Université Grenoble Alpes. From Earth, these planets appear directly next to bright stars, so their faint signals often get lost in the glare. To combat this, the CNRS team designed a chronograph — a special telegraphic tool for the JWST that blocks out a star's light, much like how the Moon blocks out the Sun during a solar eclipse. Named TWA 7b, the newly discovered planet is surrounded by a swirling disk of rocky debris and dust — remnants from the early stages of planet formation. It orbits a young star, TWA 7, which has three distinct rings, one of which is especially narrow, and is surrounded by two empty areas. The JWST revealed a source within the heart of this narrow ring. This exoplanet is 10 times smaller — roughly the size of Saturn — than any exoplanet previously observed using this method. Which has to be tiny considering the JWST gave way to six distant 'rogue' worlds, discovered by a team at Johns Hopkins University last summer. At the time, researchers believed that these worlds were potentially brown dwarfs — the astronomical term for failed stars. 'If you have an object that looks like a young Jupiter, is it possible that it could have become a star under the right conditions?' said lead study author Adam Langeveld. Other relevant discoveries made by the JWST around the same time provided data to researchers from the University of Michigan and Montreal to assume that there are potential oceans and air sources on the exoplanet dubbed LHS 1140 b, which is located within the constellation Cetus in the night sky. Most exoplanets we know about have been detected using indirect methods like measuring a star's wobble or dimming as a planet crosses in front of it — the method scientists artificially recreated to discover TWA 7 b. In the bigger picture, learning how planets like TWA 7 b form and shape their surroundings brings us one step closer to understanding the origins of planetary systems, including our own.

Eerie hidden world discovered by alien-hunting space telescope is first of its kind – and scientists nearly missed it
THE James Webb Space Telescope has discovered its first-ever exoplanet - a distant world hidden by the glare of its nearest star. The landmark discovery marks a new era for alien -hunters, according to a new study from the Paris Observatory and the University Grenoble Alpes, published in Nature today. The newly discovered exoplanet, named TWA 7 b, is in the debris disk of a young star. These disks are made up of dust and small rocks that are left over after a planet has formed. The James Webb Space Telescope (JWST) has been floating in space since 2021, and is now just over 1million miles away from Earth. For scale, that's more than 4.5 times the distance between our planet and the Moon. While it has detected other planets - these have all be previously known to astronomers on the ground. TWA 7 b is pretty big and is a similar size to Saturn, the second largest planet in our solar system. However, it still could have been easily missed, as researchers say it is one of the lightest planets ever detected. JWST's keen eye is set to enable scientists to capture images of less massive planets that are more comparable to Earth in size. While thousands of exoplanets - planets outside of our solar system - have been discovered, getting pictures of them still proves tricky. Many exoplanets lurk in the shadows of their nearest star, and therefore don't stand out enough to be visible, according to researchers. Best-ever sign of ALIEN life found on distant planet as scientists '99.7% sure of astounding biological activity signal' However, a French-produced coronagraph onboard the JWST - a tool used to block the light of a star to see nearby planets - made the new discovery possible. While it doesn't provide a direct picture of the planet, you can see its effects in the circles labelled CC #1 in the image. By masking the star, scientists have better hope of observing the objects surrounding it. The James Webb Space Telescope: an overview The James Webb Space Telescope (JWST) is a space-based observatory that is designed to complement and extend the discoveries of the Hubble Space Telescope. It is named after James E. Webb, who was the administrator of Nasa from 1961 to 1968 and played a pivotal role in the Apollo program. JWST is equipped with a 6.5-meter primary mirror, which is significantly larger than Hubble's 2.4-meter mirror, allowing it to observe much fainter objects at greater distances. It operates in the infrared spectrum, which enables it to peer through dust clouds that obscure visible light and to observe the earliest galaxies that formed after the Big Bang. The telescope was launched on 25th December 2021 and is positioned at the second Lagrange point (L2), approximately 1.5 million kilometers from Earth. This location provides a stable environment with minimal interference from Earth's heat and light. JWST's scientific goals include studying the formation of stars and planets, understanding the evolution of galaxies, and investigating the potential for life in other parts of the universe. It is a collaborative project involving Nasa, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The debris disk surrounding TWA 7's star is very clear, coming up a bright whiteish yellow in the image. It forms a near perfect disk, except for the top right corner along the R2 dotted line. It's here where the exoplanet is hiding, nearly completely obscured by the brightness of its star and nearby debris. Finding new planets in the universe helps astronomers on Earth understand more about how solar systems like ours came to be. 2

Heartbroken Welsh star issues emotional message as video shows moment it all went wrong
Heartbroken Welsh star issues emotional message as video shows moment it all went wrong The eight-cap international's impressive season ended with a crushing disappointment The moment Davies dislocated his shoulder against Perpignan (Image: Instagram: @samdavey1993 ) Welsh fly-half Sam Davies has issued an emotional statement to Grenoble supporters after his team suffered double Top 14 promotion heartbreak for the third year in a row. The 31-year-old had another impressive campaign in the Pro D2 as he pulled the strings for his side, helping them to finish top of the league table in the regular season. Having made it through to the play-off final to face underdogs Montauban, it looked as though Grenoble were finally going to jump up to the top flight, but it soon began to go wrong for Davies' side. A shock defeat to Montauban meant that Grenoble's last chance to win promotion came in the Top 14 Access Match play-off final, where they faced Perpignan, who had finished second from bottom in the top flight this season. However, after missing out in the Access Match for the last two years, it wasn't to be yet again for Grenoble, as they fell to a narrow 13-11 defeat to consign them to another season in the second tier. That match saw the talismanic Davies leave the field with a shoulder injury minutes into the contest, only to return to the action later on as he tried but ultimately failed to rally his side and lead them to victory. Having initially said that he had "no words" to convey his heartbreak in the wake of the defeat, the eight-cap Wales international has now taken to social media to issue a full statement to supporters. Article continues below He has also confirmed that he dislocated his shoulder moments into the Perpignan match, sharing a video of the incident on Instagram. "The pain never stops, but the motivation grows," he wrote. "Thank you to our wonderful supporters. I assure you, we will be back stronger. "After dislocating my shoulder four minutes into the final, here's to a challenge that raises many questions. It was difficult to play through the pain, but I would do it again and again for this team." Content cannot be displayed without consent It comes after former Ospreys and Dragons star Davies admitted he had "found the spark again" since leaving Wales for France in the summer of 2023, with the fly-half now playing the best rugby of his career. 'I wouldn't go as far as to say that I have been reborn, but rather that I found the spark again,' he told RugbyPass.'I feel appreciated and respected. Article continues below "I think I've been playing some of my best rugby. I feel I have been unshackled. I am now allowed to make mistakes without someone immediately putting me back in my place. "Grenoble allowed me to follow my instincts, while in Wales every mistake I made was put under the magnifying glass," he added. "It was a complete change of pace. "The Grenoble staff try to value the positives more than the negatives. It pushes us to be better individuals and team players."

Rugby fans storm pitch and fight as top players chased into dressing room
Rugby fans storm pitch and fight as top players chased into dressing room 15 riot police attempted to break up the violence as players fled to safety Grenoble and Perpignan fans stormed the pitch after their huge Top 14 promotion play-off match and traded blows in ugly scenes. The two teams had clashed for a place in the Top 14 next season before chaos erupted and players fled to the sanctuary of the dressing room. Grenoble, who Welsh international Sam Davies plays for, lost the match 13-11, but it's the behaviour of fans that's become the story. Footage published by Ovalie Media on X shows fans appearing to throw punches and kicks as others attempt to dispel the chaos. Fifteen French riot police officers (known as CRS), holding shields and wearing helmets, took to the field to calm things down. Sign up to Inside Welsh rugby on Substack to get exclusive news stories and insight from behind the scenes in Welsh rugby. Perpignan president Francois Riviere confirmed supporters allegedly chased Perpignan players into the changing rooms after the game. He said: "I had two players chased all the way to the locker room entrance. "They were guys who were in the locker room area, a controlled zone, but who wanted to fight my players. Article continues below "It's incredible, I've never seen anything like it! While the Grenoble staff were perfect and very kind." A wider view of the violence can be viewed below. Content cannot be displayed without consent Riviere added: "I am sorry for this atmosphere, which is not (a good) one. I have rarely seen such hostility in my career. "I was struck by this atmosphere, struck to see that you had CRS (riot police) who were forced to enter a rugby field wearing helmets. "My shirt was completely stained with blood, because I came to help supporters in difficulty! I have never seen anything like that." Article continues below For Wales international and former Dragons fly-half Davies, the loss was a second blow in as many weeks, after losing the initial Pro D2 play-off match against Montauban, who will play Top 14 rugby next season. It's three seasons in a row, now, that Grenoble have lost out on promotion. It comes as an even more frustrating outcome considering that they topped the Pro D2 with 98 points, 21 more than Montauban. Davies' electric performances have captured the French second division and his services have reportedly attracted interest from other clubs in Europe, although he signed a new deal with the club in January.
