NASA’s Chandra Observatory Records Mysterious Explosion 10.7 Billion Light-Years Away

This Hubble image shows the supernova remnant N103B (top of the image). N103B was a Type Ia supernova, located in the Large Magellanic Cloud. Owing to its relative proximity to Earth, astronomers observe the remnant to search for a potential stellar survivor of the explosion. The orange-red filaments visible in the image show the shock fronts of the supernova explosion. These filaments allow astronomers to calculate the original centre of the explosion. The filaments also show that the explosion is no longer expanding as a sphere, but is elliptical in shape. Astronomers assume that part of material ejected by the explosion hit a denser cloud of interstellar material, which slowed its speed. The shell of expanding material being open to one side supports this idea. The gas in the lower half of the image and the dense concentration of stars in the lower left are the outskirts of the rich star cluster NGC 1850. Image credit: NASA / ESA / Hubble.

The elliptical galaxy 3C186, located about 8 billion years from Earth, is most likely the result of a merger of two galaxies. This is supported by arc-shaped tidal tails, usually produced by a gravitational tug between two colliding galaxies, identified by M. Chiaberge et al. The merger of the galaxies also led to a merger of the two supermassive black holes in their centers, and the resultant black hole was then kicked out of its parent galaxy by the gravitational waves created by the merger. The bright, star-like looking quasar can be seen in the center of the image. Its former host galaxy is the faint, extended object behind it. Image credit: NASA / ESA / M. Chiaberge, STScI.

Showcase of the different types of changes identified in high-resolution images of 67P/Churyumov–Gerasimenko during more than two years of monitoring by ESA’s Rosetta spacecraft. The approximate locations of each feature are marked on the central context images. Dates of when the ‘before’ and ‘after’ images were taken are also indicated. Note that the orientation and resolution between image pairs may vary, therefore in each image set arrows point to the location of the changes, for guidance.

This Hubble image shows the remnant of SN 1987A within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The image was taken by Hubble’s Wide Field Camera 3 (WFC3) in January 2017. SN 1987A is located in the center of the image amidst a backdrop of stars. The bright ring around the central region of the exploded star is composed of material ejected by the star about 20,000 years before the actual explosion took place. The supernova is surrounded by gaseous clouds. The clouds’ red color represents the glow of hydrogen gas. The colors of the foreground and background stars were added from observations taken by Hubble’s Wide Field Planetary Camera 2 (WFPC2). Image credit: NASA / ESA / R. Kirshner, Harvard-Smithsonian Center for Astrophysics and Gordon and Betty Moore Foundation / P. Challis, Harvard-Smithsonian Center for Astrophysics.

Astronomers combined data from ALMA’s 7- and 12-m antennas to produce the sharpest possible image of RX J1347.5–1145, the center of which shows up here in the dark ‘hole’ in the ALMA observations. The energy distribution of the CMB photons shifts and appears as a temperature decrease at the wavelength observed by ALMA, hence a dark patch is observed in this image at the location of the cluster. The optical image of RX J1347.5–1145 was taken with Hubble. Image credit: NASA / ESA / Hubble / T. Kitayama, Toho University / ALMA.
