Study finds planetary waves linked to wild summer weather have tripled since 1950

Climate change has tripled the frequency of atmospheric wave events linked to extreme summer weather in the last 75 years and that may explain why long-range computer forecasts keep underestimating the surge in killer heat ...

Discovery of giant planet orbiting tiny star challenges theories on planet formation

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet.
