Shock waves

Life on Mars will face extreme stresses, including powerful shock waves and chemically harsh soil. Researchers have studied how a model organism responds to these Mars-like conditions and found that it can survive by reorganizing its cellular machinery.

For the first time, a phenomenon that astronomers have long hoped to directly image has been captured by the Near Infrared Camera (NIRCam) on the NASA/ESA/CSA James Webb Space Telescope. In this spectacular image of the Serpent Nebula, the discovery is in the northern region of this young, nearby star-forming region. NASA, ESA, CSA

Herbig-harrows are luminous regions surrounding young stars. They form when stellar winds or jets of gas ejected from these stars create shock waves that collide at high speeds with nearby gas and dust.
