What do you do when a tried-and-true method for determining the sun's chemical composition appears to be at odds with an innovative, precise technique for mapping the sun's inner structure? That was ...

This work, which verifies one of the predictions of Einstein's General Relativity, is to be published in the journal Astronomy & Astrophysics. The General Theory of Relativity, published by Albert ...

An accurate solar-irradiance spectrum is needed as an input to any planetary atmosphere or climate model. Depending on the spectral characteristics of the chosen model, uncertainties in the irradiance ...

In this paper, the full solar spectrum coverage with an absorption efficiency above 96% is attained by shell-shaped graphene-based hollow nano-pillars on top of the refractory metal substrate. The ...
