By Bobby Bascomb Scientists have identified nine planetary boundaries that help regulate a livable planet. Human activities have pushed six of those nine critical Earth systems beyond safe limits, ...

Astronomers have described the first measurements of plasma layers within an interstellar shock wave that surrounds a pulsar.

With the most powerful radio telescope in the southern hemisphere, we have observed a twinkling star and discovered an ...

Readily available but underused Doppler radar data can help predict the height of the planetary boundary layer - the lowest part of the atmosphere and ...

Abstract: The planetary boundary layer (PBL) is a crucial parameter to investigate ... and establish correlations with astronomical seeing conditions and atmospheric turbulence intensity. The PBL can ...

The SR-72 “Son of Blackbird,” successor to the iconic SR-71, reportedly achieves astonishing speeds up to Mach 6 using advanced hypersonic technologies, potentially evading modern air defenses. -Its ...

Stars are constantly vibrating because of ‘starquakes’. Listening to their sound can reveal a surprising amount of ...

At hypersonic speeds, complexities occur when the gases interact with the surface of the vehicle such as boundary layers and shock waves. Researchers were able to observe new disturbances in ...

Get Instant Summarized Text (Gist) 3D simulations of hypersonic shock waves reveal new flow disturbances, particularly breaks in the flow within shock layers around cone-shaped models at Mach 16 ...
