A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Feb. 17's annular solar eclipse occurred as the lunar disk slipped between the sun and Earth during its new moon phase. The alignment occurred as the moon travelled through a distant point in its ...

Today (Feb. 17), an annular solar eclipse will commence its journey across a remote region of Antarctica where it will be visible to more penguins than people. The partial solar eclipse portion of the ...

Abstract: The increasing global energy demand necessitates sustainable energy solutions to mitigate the adverse effects of fossil fuels. Solar energy, harnessed through Photovoltaic (PV) systems, ...

Earth exists in a bubble. Our atmosphere forms a protective barrier between everything on the planet's surface and the near-empty vastness of space. But it's not the only bubble Earth sits inside.

Abstract: This paper investigates the linear quadratic optimal output feedback control problem for an unknown linear continuous-time system. Combined with adaptive dynamic programming and optimal ...
