To make a planet reverse its path around the sun, something massive would have to force it into an altered orbit through its gravity. Astronomers have found planets around other stars with retrograde ...

Solar physicists have revealed how swirling plasma flows around sunspots 1, sculpted by the same Coriolis force that drives Earth's weather systems, shape the Sun’s rotation just beneath its surface.

Our grasp of how stars rotate is "insufficient," with implications on our ability to understand the causes of phenomena on the sun like solar flares and coronal mass ejections that cause aurora and ...

Ancient Chinese astronomers observed a solar eclipse in 709 BCE with remarkable detail. These old records are now helping scientists understand Earth's rotation changes over thousands of years. They ...

Observations of the sky recorded thousands of years ago continue to play a remarkable role in modern science, demonstrating that careful human observation has long-lasting value. One particularly ...
