With the launch of the James Webb Telescope, this edition of Pioneers in Science honors an integral member of its mission: John Mather.
New JWST data challenges our understanding of supermassive black holes
The new findings contradict most observations of supermassive black holes, making this an unprecedented discovery.
Astronomers track weather on an exoplanet that rains gemstones
The Hubble Space Telescope saw massive cyclones, storms, and weather chaos in the changing atmosphere of WASP-121b, a planet so hot it rains iron, sapphires, and rubies.
JWST captures stunning images of Uranus
The powerful telescope gave space fans an early Christmas present in the form of a detailed image of Uranus, observed using infrared light.
How ocean worlds could redefine the search for alien life
Scientists investigate “hycean” exoplanets with hydrogen-rich atmospheres and liquid water oceans, challenging traditional definitions of habitability.
Subaru Telescope shatters limit, observes supermassive black holes in the early Universe
Scientists have only observed supermassive black holes one billion years after the Big Bang, but astrophysicists have now breached this barrier.
Understanding gravitational waves: Ripples in spacetime explained
The universe is ringing with gravity, but humanity is only just beginning to hear the nuance of this cosmic symphony.
Time ran slowly in the early Universe, just as Einstein predicted
Using quasars as ticking cosmic clocks, scientists took a journey back in time, discovering time progressed five times slower just after the Big Bang.
JWST provides unprecedented look at exoplanet WASP-39b
New observations of WASP-39b with the JWST has provided the clearest, most detailed picture of an exoplanet to date.
Upper mass limit of massive stars revisited
Physicists at the Gemini Observatory have found a new mass limit for massive stars, and found it to be lower than previously thought.
