Sun radiation

#HVAC_ENG Solar energy is the result of electromagnetic radiation released from the sun by the thermonuclear reactions occurring inside its core. All of the energy resources on earth originate from the sun (directly or indirectly), except for nuclear, tidal, and geothermal energy.

The Sun is the Earth's principal source of energy and climate driver. Yet sometimes it sends more light to the Earth than other times. Astronomers working with Natalie Krivova at the Max Planck Institute for Solar System Research in Göttingen take these fluctuations in solar radiation into account in their models to find out whether they contribute to global warming or counteract it.

You probably already know that outer space is a near-perfect vacuum; so, how does heat travel through space?

(Phys.org) —Scientists from the Heidelberg Max Planck Institute for Nuclear Physics (MPIK) in cooperation with DESY (Hamburg) at the synchrotron PETRA III have investigated for the first time X-ray absorption of highly charged iron ions. A transportable ion trap developed at MPIK was used for generation and storage of the ions. The high-precision measurements provide important new insight into the role of highly charged ions in astrophysical plasmas, e. g. for radiation transport inside…

In addition to serving the earth as a shield against the sun's radiation, the magnetic field gives us one of the most spectacular phenomena: the Aurora Borealis!

The hot material, known as a Coronal Mass Ejection (CME) erupted from our closest star on Jan. 30 following an enormous solar flare.

Imagine if one day the internet was down not just in your neighborhood, but across the globe, knocked out by a threat from space: an enormous solar superstorm. It sounds like science fiction, but a…
