NASA’s Solar Dynamics Observatory Sees Mid-Level Solar Flare

The Sun emitted a significant solar flare, peaking at 10:58 a.m. EDT on September 28. This SDO image shows a subset of extreme UV light that highlights the extraordinarily hot material in flares and which is typically colorized in red. Image credit: NASA / SDO.

The upper two panels of this graphic represent a possible explanation for a recent increase in X-ray flares from Sagittarius A* seen by three X-ray telescopes. As part of a long monitoring campaign, astronomers observed the black hole as a mysterious object called G2 appeared to pass close to the black hole. The timing of G2’s passage could suggest that material from G2 caused the surge in X-ray activity, but it is also possible that this unrelated behavior of Sagittarius A*. The bottom panel is a view of the region around the black hole where red, green, and blue represent low, medium, and high-energy X-rays detected by NASA’s Chandra X-ray Observatory. Sagittarius A* itself is not visible in this image, but is embedded in the white dot at the end of the arrow. Image credit: NASA / CXC / MPE / G.Ponti et al. / M.Weiss.

This image shows the spiral galaxy NGC 1313. The very active state of this galaxy is very evident from the image, showing many star formation regions. A great number of supershell nebulae, that is, cocoon of gas inflated and etched by successive bursts of star formation, are visible. The green nebulosities are regions emitting in the ionized oxygen lines and may harbour clusters with very hot stars. This composite image is based on images obtained with the FORS1 instrument on one of the 8.2-m Unit Telescope of ESO’s Very Large Telescope. Astronomers determined that this galaxy harbors a black hole 5,000 times more massive than our Sun. Image credit: ESO.

This image shows the Sculptor Dwarf Galaxy, a close neighbor of our own Milky Way Galaxy. Despite their proximity, both galaxies have very distinct histories and characters. This galaxy is much smaller, fainter and older than the Milky Way and appears here as a cloud of faint stars filling most of the image. Many other much more distant galaxies can be seen shining right through the sparse stars of the galaxy. Image credit: ESO.

This image was taken by NASA’s Solar Dynamics Observatory at 3:12 a.m. EDT on September 13, 2015. The edge of Earth, visible near the top of the frame, appears fuzzy because Earth’s atmosphere blocks different amounts of light at different altitudes. On the left, the Moon’s edge is perfectly crisp, because it has no atmosphere. This image was taken in extreme UV wavelengths of 171 angstroms. Though this light is invisible to our eyes, it is typically colorized in gold. Image credit: NASA / SDO.

These panels show different components of near-infrared background light detected by the NASA/ ESA Hubble Space Telescope in deep-sky surveys. The one on the upper left is a mosaic of images taken over a ten-year period. When all the stars and galaxies are masked, the background signals can be isolated, as seen in the second and third panels. The one on the upper right reveals ‘intrahalo light’ from rogue stars torn from their host galaxies, and the lower panel captures the signature of the first galaxies formed in the Universe.
