SINGAPORE He was the first to discover a planet outside the solar system, but his work was dismissed for a decade before being rightfully recognised with the 2019 Nobel Prize in Physics.
Delivering the opening lecture of the 11th Global Young Scientists Summit at the Singapore University of Technology and Design on Tuesday, Professor Didier Queloz shared about his scientific journey as an astronomer.
He specialises in exoplanets, looking for planets that orbit sun-like stars outside the solar system.
The Swiss Nobel laureate was the harbinger of the exoplanet revolution, which has catalysed the discovery of more than 5,000 exoplanets to date.
Yet, even he and his supervisor, Professor Michel Mayor, doubted their own discovery in 1995.
Nobody was expecting a planet back then, so it was a big surprise when I saw the data. I found the planet and said: Whats going on? I thought something was wrong with the equipment, but after checking, I realised there really was something orbiting that star, Prof Didier, 56, told The Straits Times in an interview.
First I had to convince Michel that I was right, then the scientific community, which was really tough. For the next 10 years, nobody believed it, so it was a rough time for me as a young scientist, said Prof Didier, who was a PhD student at the University of Geneva at that time.
Only when the physics was more understood and established did people start to realise, oh, that guy did it.
Prof Didiers discovery of a class of giant gas planets closely orbiting their parent star, known as hot Jupiters, upset existing theories about the formation of the solar system and other planetary systems. Hot Jupiters contradicted predictions that only rocky planets orbit near the parent star, while larger gas planets do so further away.
Before his findings, theories were based only on observations made in the solar system. Astronomers are now working on theories that account for the migration of gas giants from outer to inner orbits.
The first shock was that the theory was incomplete, nobody would have guessed that planets such as gas giants could move around in their system. The second shock was that we (the solar system) may not be the dominant structure in the universe.
Prof Didier, who is currently a professor of physics at the University of Cambridges Cavendish Laboratory, plans to continue leading the hunt for Earth-like exoplanets that might support life.
However, current detectors are not sensitive enough to do so.
Im a bit upset by the fact that we have not found an Earth-like planet, so Im helping to set up a new kind of equipment to detect these exoplanets. I would also like to establish a chemical pathway for paving the way for looking for life on other planets. I have teamed up with chemists, geochemists, biochemists and earth scientists to collaborate in this area.
When asked what he feels is the main takeaway from his success, Prof Didier credited his obsessive curiosity that enables him to persevere with his beliefs and ignore the naysayers. He aims to continue probing for the next astronomical breakthrough.
We believed we were the centre of the universe. We believed everything was orbiting around us. We believed the solar system was this then we realised the universe is expanding and so on. Id expect that our next breakthrough will be one where we find life plenty in the universe, where we realise how boring and insignificant we are.
The summit, organised by the National Research Foundation and being held from Jan 17 to Jan 20, features lectures and panel discussions with 21 eminent scientists, including Nobel laureates and winners of the Millennium Technology Prize, awarded by independent foundation Technology Academy Finland.

The last-place Washington Nationals fired president of baseball operations Mike Rizzo and manager Davey Martinez, the team announced Sunday.
Rizzo, 64, and Martinez, 60, won a World Series with the Nationals in 2019, but the team has floundered in recent years. This season, the Nationals are 37-53 and stuck at the bottom of the National League East after getting swept by the Boston Red Sox this weekend at home. Washington hasn’t finished higher than fourth in the division since winning the World Series.
“On behalf of our family and the Washington Nationals organization, I first and foremost want to thank Mike and Davey for their contributions to our franchise and our city,” principal owner Mark Lerner said in a statement. “Our family is eternally grateful for their years of dedication to the organization, including their roles in bringing a World Series trophy to Washington, D.C.
“While we are appreciative of their past successes, the on-field performance has not been where we or our fans expect it to be. This is a pivotal time for our club, and we believe a fresh approach and new energy is the best course of action for our team moving forward.”
Mike DeBartolo, the club’s senior vice president and assistant general manager, was named interim GM on Sunday night. DeBartolo will oversee all aspects of baseball operations, including the MLB draft. An announcement will be made on the interim manager Monday, a day before the club begins a series against the St. Louis Cardinals.
Rizzo has been the top decision-maker in Washington since 2013, and Martinez has been on board since 2018. Under Rizzo’s leadership, the team made the postseason four times: in 2014, 2016, 2017 and 2019. The latter season was Martinez’s lone playoff appearance.
“When our family assumed control of the team, nearly 20 years ago, Mike was the first hire we made,” Lerner said. “Over two decades, he was with us as we went from a fledging team in a new city to World Series champion. Mike helped make us who we are as an organization, and we’re so thankful to him for his hard work and dedication — not just on the field and in the front office, but in the community as well.”
The Nationals are in the midst of a rebuild that has moved slower than expected, though the team didn’t augment its young core much during the winter. Led by All-Stars James Wood and MacKenzie Gore, Washington has the second-youngest group of hitters in MLB and the sixth-youngest pitching staff.
The team lost 11 straight games in a forgettable stretch last month. And during a 2-10 run in June, Washington averaged just 2.5 runs. Since June 1, the Nationals have scored one run or been shut out seven times. In Sunday’s 6-4 loss to Boston, they left 15 runners on base.
There was industry speculation over the winter that the Nationals would spend money on free agents for the first time in several years, but that never materialized. Instead, the team made minor moves, signing free agents Josh Bell and Michael Soroka, trading for first baseman Nathaniel Lowe and re-signing closer Kyle Finnegan. Now, the hope is a new management team, both on and off the field, can help change the franchise’s fortunes.
The rosters for the 2025 MLB All-Star Game will feature 19 first-timers — and one legend — as the pitchers and reserves were announced Sunday for the July 15 contest at Truist Park in Atlanta.
Los Angeles Dodgers left-hander Clayton Kershaw, a three-time Cy Young Award winner who made his first All-Star team in 2011, was named to his 11th National League roster as a special commissioner’s selection.
Kershaw, who became only the fourth left-hander to amass 3,000 career strikeouts, is 4-0 with a 3.43 ERA in nine starts after beginning the season on the injured list. He joins Albert Pujols and Miguel Cabrera as a legend choice, after the pair of sluggers were selected in 2022.
Kershaw said he didn’t want to discuss the selection Sunday.
Overall, the 19 first-time All-Stars is a drop from the 32 first-time selections on the initial rosters in 2024.
Kershaw would be the sentimental choice to start for the National League, although Pittsburgh Pirates ace Paul Skenes, who leads NL pitchers in ERA and WAR, might be in line to start his second straight contest. Philadelphia Phillies right-hander Zack Wheeler, a three-time All-Star, is 9-3 with a 2.17 ERA after Sunday’s complete-game victory and also would be a strong candidate to start.
“I think it would be stupid to say no to that. It’s a pretty cool opportunity,” Skenes said about the possibility of being asked to start by Dodgers manager Dave Roberts. “I didn’t make plans over the All-Star break or anything. So, yeah, I’m super stoked.”
Kershaw has made one All-Star start in his career, in 2022 at Dodger Stadium.
Among standout players not selected were New York Mets outfielder Juan Soto, who signed a $765 million contract as a free agent in the offseason, and Dodgers shortstop Mookie Betts, who had made eight consecutive All-Star rosters since 2016.
Soto got off to a slow start but was the National League Player of the Month in June and entered Sunday ranked sixth in the NL in WAR among position players while ranking second in OBP, eighth in OPS and third in runs scored.
Earning his fifth career selection but first since 2021 is Texas Rangers righty Jacob deGrom, who is finally healthy after making only nine starts in his first two seasons with the Rangers and is 9-2 with a 2.13 ERA. He has never started an All-Star Game, although Skubal or Brown would be the favorite to start for the AL.
“Red carpet, that’s my thing,” Chisholm said. “I do have a ‘fit in mind.”
Rosters are expanded from 26 to 32 for the All-Star Game. They include starters elected by fans, 17 players (five starting pitchers, three relievers and a backup for each position) chosen in a player vote and six players (four pitchers and two position players) selected by league officials. Every club must be represented.
Acuna, Wood and Raleigh are the three All-Stars who have so far committed to participating in the Home Run Derby.

NEW YORK — The New York Yankees were seemingly in deep trouble Sunday when Juan Soto cracked a pitch to left field in the seventh inning.
The New York Mets, down two runs, were cooking up a rally with no outs. Francisco Lindor stood at first base, Pete Alonso loomed on deck, and Brandon Nimmo was in the hole. This was the heart of the Mets’ potent lineup. Given the Yankees’ recent woes, fumbling their two-run lead and suffering a Subway Series sweep at the hands of their neighbors — and a seventh straight loss — seemed almost fated.
Then Cody Bellinger charged Soto’s sinking 105 mph line drive, made a shoestring catch and fired a strike to first base for an improbable double play to secure a skid-snapping 6-4 win — and perhaps rescue the Yankees from another dreadful outcome.
“Considering the context of this week and everything,” Yankees manager Aaron Boone said, “that’s probably our play of the year so far.”
Soto’s line drive off Mark Leiter Jr. had a 10% catch probability, according to Statcast, but Bellinger, a plus defender at multiple positions who started at first base Saturday, was just able to snatch it before it touched the grass. Certain that he caught it clean, he made an 89.9 mph toss that reached first baseman Paul Goldschmidt on a line, over Lindor, who didn’t slide into the bag.
“I saw it in the air and had a really good beat on it,” said Bellinger, who went 2-for-3 with a double and a walk at the plate.
The Mets challenged the catch, but the call stood.
“That was incredible,” said Yankees right fielder Aaron Judge, who swatted his 33rd home run of the season in the fifth inning. “I’ve never seen something like that on the field.”
For the past week, a stretch Boone described as “terrible” for his ballclub, poor defense has been an issue for the Yankees. Physical errors. Mental lapses. Near disasters. The sloppiness helped sink a depleted pitching staff, more than offsetting the offense’s strong production.
That combination produced the team’s second six-game losing streak in three weeks and a three-game deficit in the American League East standings behind the first-place Toronto Blue Jays.
The surging Blue Jays won again Sunday to extend their winning streak to seven games and keep their division lead at three games, but Bellinger’s glove and arm ensured it didn’t grow to four.
“That was an unbelievable play,” Goldschmidt said. “Amazing catch and absolute cannon to me at first. To make that play was a game-changing play and potentially game-winning play for us today. And we needed it.”
