Solar Storm Whips Away Comet Nishimura's Tail in Stunning Time-lapse

NASA's STEREO-A spacecraft captured video footage of Comet Nishimura being hit by a powerful solar storm, causing its tail to be temporarily blown away. The green comet, discovered by amateur astronomer Hideo Nishimura, survived a close encounter with the sun and has a highly elliptical orbit that brings it into the inner solar system every 430 years. Despite being bombarded by the sun, the comet remains on its original trajectory and may be visible again in the future.

NASA's STEREO-A Spacecraft Returns Home After 17-Year Journey

NASA's STEREO-A spacecraft, after nearly 17 years, is making its first Earth flyby, providing a unique opportunity for collaboration with other NASA missions and new insights into the sun. STEREO-A, along with its twin STEREO-B, launched in 2006 and achieved the first stereoscopic view of the sun. During the Earth flyby, STEREO-A will combine views with other spacecraft to achieve 3D vision and gather measurements of active regions and coronal loops. The mission will also provide multipoint measurements of Earth-directed coronal mass ejections, offering a better understanding of their magnetic field evolution. As the sun approaches solar maximum, STEREO-A will experience a fundamentally different sun, providing valuable knowledge about solar activity.
