An exciting new tool that researchers are describing as the "holy grail of astrobiology" may finally answer once and for all if there is life on other planets.
For the first time ever, researchers using the James Webb Space Telescope have successfully measured the light coming from a sub-Neptune-sized exoplanet that orbits a star only 40 light years away.
A new paper from the University of Tokyo suggests that astrobiologists could find signs of alien life in particles of space dust that have been ejected from exoplanets and traveled across the vastness of space to reach earth.
