Venus' extreme surface heat drives swirling winds in upper atmosphere, study finds | Space

Scientists have shown how the swirling winds and searing heat on Venus work together in a revealing new study.

The surface of Venus is hot enough to melt lead with temperatures averaging 872 degrees Fahrenheit (467 degrees Celsius). This extreme heat is maintained by a thick atmosphere of carbon dioxide that traps the heat on the planet in a greenhouse effect .

Laser-Powered Sails Would be Great for Exploring the Solar System too - Universe Today

In particular, missions planners and engineers are investigating Directed Energy (DE) propulsion, where laser arrays are used to accelerate light sails to relativistic speeds (a fraction of the speed of light).

The study was conducted by Ho-Ting Tung , an aerospace engineering grad student from UCLA, and assistant professor Artur R. Davoyan , both of whom are members of the Davoyan Research Group (DRG), of which Prof. Davoyan is the founder.

Fine-tuning for the Big Bang | Tigra Scientifica | thetigercu.com

The first detector to be calibrated is the Near Infrared Camera (NIRCam), which can detect wavelengths just outside of the visible spectrum and offers a clearer image than cameras that only detect visible light.

The remaining detectors will collect the light that passes through the NIRCam and record the wavelengths for image outputting. Once all detectors are fully functional, NASA operators will test the 17 observation modes on reference objects with known brightness and position.
