A year later, astronomers at Copenhagen University tracked down a sugar molecule in a distant star system. That molecule is an essential component of ribonucleic acid or RNA, a molecule that is critical for most biological functions.In 2023, astronomers found traces of organic molecules in the gases around one of Saturn’s moons, Enceladus.

And in mid-2024, scientists identified five greenhouse gases that they said would be telltale signs of life on any other planet.But the journey of science is also about setbacks. In 2005, two NASA scientists claimed they had found potential traces of extraterrestrial life on Mars after they discovered signs of methane there. Yet those findings eventually did not hold up to scientific scrutiny and NASA distanced itself from their conclusions.The Cambridge-led team has found DMS and DMDS with 99.7 percent certainty. But while that might sound like a near-perfect score, it is far from what is accepted as the benchmark for a new discovery by the exacting standards of science.

For their conclusions to be considered bulletproof, they need to get to what is known as the five-sigma threshold – 99.99994 percent certainty.The astronomers believe that more hours on the James Webb telescope could help them reach that level of confirmation.

“Decades from now, we may look back at this point in time and recognise it was when the living universe came within reach,” said Madhusudhan. “This could be the tipping point, where suddenly the fundamental question of whether we’re alone in the universe is one we’re capable of answering.”

Susie Wiles, an ally of President Donald Trump, was reportedly the target of an impersonation campaign using her voice.But last year, a constitutional amendment paved the way for Sunday's controversial election.

It was a final, parting victory for outgoing PresidentAndres Manuel Lopez Obrador

, the political mentor of Mexico's current leaderLopez Obrador had long clashed with Mexico's Supreme Court. During his six-year term, many of his signature policy proposals had come before the court.
