Live view of the Sun from SOHO. From 1.5 million kilometres away from Earth, the Solar and Heliospheric Observatory ( SOHO) constantly watches the Sun, returning spectacular pictures and data of the storms that rage across its surface. On this page you can see the latest images from two instruments on board SOHO: the Extreme ultraviolet Imaging ...
Storms on the Sun are caused by disturbances to its complex magnetic fields. These "magnetograms," taken by the MDI instrument on SOHO, detect the strength and location of the magnetic fields on the Sun. Magnetograms show "line-of-sight" magnetic fields -- that is, those either coming directly towards us or going away from us.
Solar Orbiter’s first view of the Sun is closest ever. This animation shows a series of views of the Sun captured with the Extreme Ultraviolet Imager (EUI) on ESA/NASA’s Solar Orbiter on May 30, 2020. They show the Sun’s appearance at a wavelength of 17 nanometers, which is in the extreme ultraviolet region of the electromagnetic spectrum.
The National Solar Observatory (NSO) is the national center for ground-based solar physics in the United States (www.nso.edu) and is operated by the Association of Universities for Research in Astronomy (AURA) under a cooperative agreement with the National Science Foundation Division of Astronomical Sciences.
The first images from ESA/NASA’s Solar Orbiter are now available to the public, including the closest pictures ever taken of the Sun. Solar Orbiter is an international collaboration between the European Space Agency, or ESA, and NASA, to study our closest star, the Sun. Launched on Feb. 9, 2020 (EST), the spacecraft completed its first close pass of the Sun in mid-June.
The sun as seen by Solar Orbiter in extreme ultraviolet light from a distance of roughly 46 million miles (75 million kilometers). The image is a mosaic of 25 individual images taken on March 7 by ...
NuSTAR sees high-energy X-rays that appear at only a few locations, where the hottest material is present in the Sun's atmopshere. By contrast, Hinode's XRT and SDO's AIA detect detect wavelengths emitted across the entire face of the Sun. The hotspots observed by NuSTAR might be caused by collections of nanoflares, or small outbursts of heat ...
