New planet discovered 35 light years away
The team utilised NASA's TESS (Transiting Exoplanet Survey Satellite) space telescope to identify the planet, named L 98-59 f. It is one of five planets orbiting a red dwarf star in the L 98-59 system.
Located in the habitable zone
L 98-59 f lies within the star's habitable zone, the region where liquid water could potentially exist. It receives a similar amount of stellar energy as Earth does from the Sun, making it a candidate for possible habitability.
A compact and diverse planetary system
The L 98-59 system was previously believed to host only four planets. However, after extensive analysis of data from both space- and ground-based telescopes, the fifth planet was identified.
Detected through stellar motion
Unlike the other planets in the system, L 98-59 f does not transit between its star and Earth, making it invisible to standard transit detection methods. Instead, scientists detected it by observing subtle shifts in the motion of its host star — a method known as the radial velocity technique.

Five astronauts depart ISS for return to Earth
Long journey home The returning astronauts — Americans Anne McClain and Nichole Ayers, Japan's Takuya Onishi, and Russian cosmonaut Kirill Peskov — are expected to spend over 17 hours in the capsule before splashing down off the coast of California at 15:33 GMT on Saturday. Milestone for NASA's Commercial Crew Programme Their return marks the conclusion of the 10th crew rotation mission under NASA's Commercial Crew Programme, which partners with private industry, including SpaceX, to send astronauts to the ISS following the retirement of the Space Shuttle. Controlled descent and recovery The Dragon capsule detached from the ISS at 22:15 GMT on Friday. Upon re-entry, the spacecraft will slow down significantly, first due to Earth's atmosphere and then with the help of large parachutes for a safe ocean landing. A SpaceX recovery ship will retrieve the capsule and bring it aboard, allowing the astronauts to breathe Earth's air for the first time in months. Scientific contributions in orbit Known as Crew-10, the team conducted numerous experiments during their mission, including research into plant growth in microgravity and how cells respond to gravitational changes. Stranded astronauts finally replaced This mission also marked a turning point for two American astronauts, Butch Wilmore and Suni Williams, who were unexpectedly stranded on the ISS for nine months after the Boeing Starliner they launched on developed propulsion issues. They had originally planned to spend just eight days in orbit. Looking ahead NASA recently announced Wilmore's retirement after 25 years of service. Meanwhile, a new crew — US astronauts Zena Cardman and Mike Fincke, Japan's Kimiya Yui, and Russian cosmonaut Oleg Platonov — arrived at the ISS last week for a six-month mission.

Apollo 13 captain who coined 'Houston, we have a problem' dies at age 97
Jim Lovell, the US astronaut who led the ill-fated Apollo 13 mission and helped guide its crew safely back to Earth after a mid-flight explosion, died at the age of 97 on Thursday. Mr Lovell was at the centre of one of Nasa 's most dramatic episodes when an oxygen tank on the spacecraft exploded on April 13, 1970, two days after launch. The mission was meant to be the third crewed landing on the Moon, but the explosion damaged its power and life-support systems. 'Houston, we've had a problem,' Mr Lovell told mission control in words that have since become part of space-flight history. The phrase was later popularised as 'Houston, we have a problem'. Tributes from space community Tributes to Mr Lovell came from Nasa, former astronauts and wider space community after his death was announced on Friday. Nasa acting administrator Sean Duffy said in a statement that the agency sent its condolences to the family of Mr Lovell, 'whose life and work inspired millions of people across the decade'. 'Jim's character and steadfast courage helped our nation reach the Moon and turned a potential tragedy into a success from which we learnt an enormous amount,' he said. 'We mourn his passing even as we celebrate his achievements.' Dr Buzz Aldrin, the second person to work on the Moon, said that was he was 'grieving the loss of one of my best friends'. 'Our mutual respect had no limits. The Gemini XII mission we flew together paved the way for the Apollo missions. Heartfelt condolences to Jim's family. Farewell Jim. You will be missed, my friend. Godspeed,' he said. Impressive career After the explosion aboard the Apollo 13 mission, Mr Lovell and his crewmates, Jack Swigert and Fred Haise, worked with engineers on the ground over the next four days to come up with solutions. They conserved power, repurposed spacecraft systems and navigated a complex return trajectory that brought them home to a safe splashdown in the Pacific Ocean on April 17. The episode was later described by Nasa as a 'successful failure' because, while the original mission was lost, the crew's survival was more important. Mr Lovell's space career spanned four missions, including two to the Moon, though he landed on the surface. He was command module pilot of Apollo 8 in 1968, the first mission to orbit the Moon, giving humanity its first close-up views of the lunar surface and the famous Earthrise photograph taken by William Anders. Earlier, he flew on Gemini 7 and Gemini 12, pioneering the rendezvous, docking and spacewalking techniques that were essential in the Apollo programme. After retiring from Nasa and the US Navy in 1973, Mr Lovell co-wrote the memoir Lost Moon, which became the basis for the 1995 film Apollo 13. Actor Tom Hanks portrayed him on screen, and Mr Lovell made a cameo appearance in the film. Mr Lovell is survived by his four children. His wife, Marilyn, who he was married to for almost 70 years, died in 2023.

Five astronauts leave space station for trip back to Earth
After nearly five months onboard the International Space Station, an international crew of five astronauts began their descent back down to Earth on a SpaceX capsule on Friday. US astronauts Anne McClain and Nichole Ayers, Japan's Takuya Onishi and Russian cosmonaut Kirill Peskov are expected to spend more than 17 hours in the capsule before splashing down off California's coast at 1533 GMT on Saturday. Their return will mark the end of the 10th crew rotation mission to the space station under NASA's Commercial Crew Program, which was created to succeed the Space Shuttle era by partnering with private industry. The Dragon capsule of billionaire Elon Musk's SpaceX company detached from the International Space Station (ISS) at 2215 GMT on Friday. The capsule's dizzying drop back down to Earth will be slowed when it re-enters Earth -- and then again by huge parachutes to soften its landing. After the capsule splashes down, it will be recovered by a SpaceX ship and hoisted aboard. Only then will the astronauts be able to breathe Earth's air again, for the first time in months. The astronauts, known as Crew-10, conducted numerous scientific experiments during their time on the space station, including studying plant growth and how cells react to gravity. Their launch into space in March was heavily scrutinized because it finally allowed two US astronauts -- who had been unexpectedly stuck onboard the space station for nine months -- to return home. When they launched in June 2024, Butch Wilmore and Suni Williams were only supposed to spend eight days in space on a test of the Boeing Starliner's first crewed flight. However, the spaceship developed propulsion problems and was deemed unfit to fly back, leaving them stranded in space. NASA announced this week that Wilmore has decided to retire after 25 years of service at the US space agency. Last week, US astronauts Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russian cosmonaut Oleg Platonov boarded the ISS for a six-month mission. Agence France-Presse
