July 9, 2025, saw the Earth spin through one of its shortest days on record a fleeting, nanosecond instant that passed unnoticed by most, but sent ripples within the domain of high-precision ...

3-D Rotation Representation of Multiple Reflections and Parametric Model for Bistatic Scattering From Arbitrary Multiplate Structure ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

While the Earth’s rotation changes over cosmic timescales, it also fluctuates on daily ones. We all know that a day lasts 24 hours, or 86,400 seconds, but that’s not perfectly accurate.

The Indian National Space Promotion and Authorisation Centre (IN-SPACe) will invite final bids for private participation in establishing an Earth observation constellation under the Public-Private ...

Possibly due to her own insecurities, the Leader of the Opposition is still committed to the random rotation model of deputation. Presumably hapless shadow cabinet members have to assemble in her ...

Earth could be about to record its fastest-ever rotation. Since 2020, Earth has been rotating faster than at any point since records began in 1973, with each successive year producing the shortest ...

In this paper, a three-dimensional (3D) non-stationary geometry-based stochastic model (GBSM) is proposed for low-altitude unmanned aerial vehicles (UAVs) multiple-input-multiple-output (MIMO) ...

Strange signals defy physics models, potentially hinting at unknown particles or phenomena beyond the Standard Model.
