‘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 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.
