Magnetic Field Maps of the Sun’s Corona

A purple and yellow image shows flares coming off the side of the sun and looping back. An inset shows the actual data of the coronal map  in black and white
The NSF Daniel K. Inouye Solar Telescope presents its first map of the solar coronal magnetic field signals as measured using the Zeeman Effect. The Zeeman Effect polarizes the coronal emission, which requires the advancements of the Inouye Solar Telescope to measure as its signals are only a few parts per billion of the Sun’s surface brightness. The background image identifies the region observed in detail by Inouye as imaged by NASA’s Solar Dynamics Observatory in ultraviolet light. Credit: NSF/NSO/AURA

Searching for Planets in the Alpha Centauri system

This image shows the closest stellar system to the Sun, the bright double star Alpha Centauri AB and its distant and faint companion Proxima Centauri. In late 2016 ESO signed an agreement with the Breakthrough Initiatives to adapt the VLT instrumentation to conduct a search for planets in the Alpha Centauri system. Such planets could be the targets for an eventual launch of miniature space probes by the Breakthrough Starshot Initiative. Credit: ESO/B.
