How many times have you said, “I wish the days were longer”? Well, NASA scientists say the construction of China’s Three ...
Astronomers directly imaged a faint companion star orbiting Betelgeuse, solving a decades-old mystery about its strange ...
This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...
We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...
Abstract: In this brief, a global finite-time attitude control algorithm is proposed for flexible spacecraft without angular velocity measurement. First, a global finite-time observer is designed to ...
Abstract: Beam tracking is a promising technology in mmWave-enabled cellular-connected unmanned aerial vehicle (UAV) communications. However, conventional beam tracking schemes always incur a large ...
Our local “newspaper,” The Villages Daily Sun, is a disgusting example of news bias, total politicization of “news,” news censoring in reporting and more. MILLIONS of people including what looked like ...
