‘Are we ready for this?’: Wknd interviews the astrophysicist who captured signs

At 45, Nikku Madhusudhan has made the discovery of a lifetime. How did he know where to look? What else could these gas signatures be? An exclusive interview.

The gas signatures Madhusudhan and his team at Cambridge have detected are the surest signs of life outside Earth that humanity has ever encountered. How we interpret and build on this data, from 124 light years away, will be crucial, he says.

Scientists find ‘strongest evidence’ yet of life beyond our solar system

Scientists using NASA's James Webb Telescope found signs of possible extraterrestrial life on exoplanet K2-18 b, detecting biosignature gases DMS and DMDS.

Scientists find strongest evidence yet of life on an alien planet

SPACE-EXPLORATION/PLANET (PIX, TV):Scientists find strongest evidence yet of life on an alien planet

A graph shows the observed transmission spectrum of the habitable zone exoplanet K2-18 b using the James Webb Space Telescope MIRI spectrograph instrument. The vertical shows the fraction of star light absorbed in the planet's atmosphere due to molecules in its atmosphere. The data are shown in the yellow circles with the 1-sigma uncertainties. The curves show the model fits to the data, with the black curve showing the median fit and the cyan curves outlining the 1-sigma intervals of the model fits. The absorption features attributed to dimethyl sulphide and dimethyl disulphide are indicated by the horizontal lines and text. The image behind the graph is an illustration of a hycean planet orbiting a red dwarf star. This image was obtained by Reuters on April 16, 2025. A. Smith, N.

‘City-killer’ asteroid 2024 YR4 no longer threat to Earth, but may hit moon

The asteroid 2024 YR4 has a 2% chance of hitting the moon in December 2032, a slight rise from NASA’s February estimate of 1.7%.

A rarely seen prelude to a Supernova shows a super-bright, massive Wolf-Rayet star in a composite image taken by the James Webb Telescope and released by NASA on March 14, 2023. The star, WR 124, is 15,000 light-years away in the constellation Sagittarius and is 30 times the mass of our Sun. As the ejected gas moves away from the star and cools, cosmic dust forms and glows in the infrared light detectable by Webb. The Wolf-Rayet phase is a fleeting stage that only some stars go through soon before they explode. The origin of cosmic dust that can survive a supernova blast is of great interest to astronomers for multiple reasons. Dust shelters forming stars, gathers together to help form planets, and serves as a platform for molecules to form and clump together, including the building blocks of life on Earth. (NASA/ESA via REUTERS)
