This graphic shows X-rays that NASA’s Chandra X-ray Observatory detected from the dwarf galaxy Mrk 462. This X-ray emission (inset) is important because it reveals the presence of a growing supermassive black hole within this relatively small galaxy. The mass contained in this black hole -- about 200,000 times the mass of the Sun -- provides information to astronomers about how some of the earliest black holes in the Universe may have formed and grown billions of years ago. The background panel is an optical image from the Pan-STARRS telescope in Hawaii. There are several galaxies that are part of the HCG068 galaxy group on the left-hand side of the image. The galaxy that is emitting copious amounts of X-rays, however, is the much smaller galaxy located to the lower right of the image (marked by the arrow).

This artist’s illustration depicts what Chu et al. think is happening in the binary system KPD 0005+5106. The data suggest the white dwarf (blue sphere) is blasting a companion object (brown and red object on right), which is either a low-mass star or planet, with waves of heat and radiation. The white dwarf is also pulling material from the companion into a disk around itself, which the artist shows in orange, before it slams into its north and south poles. This process is contributing to the destruction of the companion through powerful gravitational forces. Image credit: NASA / CXC / M. Weiss / ASIAA / Chu et al.

MG B2016+112: the X-ray light from one of the objects on the left (purple) has been warped by the gravity of the intervening galaxy to produce two beams and X-ray sources (A and B) detected in the Chandra image, which is represented by the dashed square on the right; the X-ray light from the fainter object (blue) produces an X-ray source (C) that has been amplified by the galaxy to be as much as 300 times brighter than it would have been without the lensing; the Chandra image is shown in the inset; these two X-ray-emitting objects are likely a pair of growing supermassive black holes or a growing supermassive black hole and a jet.
