We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. ...

... The Sun is the closest star to us, and a regular object in our Galaxy. Solar activity manifests itself, primarily, in solar flares - episodic explosive energy release in the form of electromagnetic radiation and high energy particles (electrons and protons). The nature of the flares is related to cyclic variations of global and local magnetic fields in the atmosphere of the Sun. ... Such formations are called active regions. ...

The infrared satellite IRAS. The main task of the IRAS telescope was the search of a longwave infrared radiation, composing the maps of the sky in the infrared range. IRAS telescope helped to discover new galaxies, to study the properties of the dust particles in our galaxy, which opens the character of a star hiding somewhere in the sky. ... For 6 months of observation it discovered 6 new asteroids, allowed to find out the nature of the dust zones between Mars and Jupiter orbits. ...
