    Coronal heating is a topic dedicated to explaining how the corona may be heated up to a temperature of millions of degrees, far above that of the photosphere. To transport magnetic energy into the corona, Alfvén-wave turbulence is a promising candidate. However, how the wave is generated in the corona is still an open question. [...]

    Astronomers have carried out very-long-baseline interferometric (VLBI) observations of the quasar IRAS F11119+3257 using the European VLBI Network (EVN). They found that the object has a high velocity two-sided jet, a finding detailed in a paper published March 25 on the arXiv pre-print repository. [...]

    The coronavirus COVID-19 pandemic has virtually paralyzed daily life as we know it. Even when the spread of this highly infectious disease has been stemmed, the world will face huge challenges getting back to normal. To help support experts working in Europe's research centers and technical organizations during these unprecedented times, ESA has issued two new initiatives related to understanding the effects that COVID-19 is imposing on society, the economy and the environment. [...]
