Kks3: Hubble Discovers New Neighbor Galaxy to Milky Way

This image shows the newly discovered dwarf galaxy Kks3. The core of the galaxy is the right hand object at the top center of the image, with its stars spreading out over a large section around it; the left hand of the two objects is a much nearer globular star cluster.

A new neighbor of our Milky Way Galaxy has been discovered with the Advanced Camera for Surveys (ACS) instrument on NASA’s Hubble Space Telescope. This image shows the newly discovered dwarf galaxy Kks3. The core of the galaxy is the right hand object at the top center of the image, with its stars spreading out over a large section around it; the left hand of the two objects is a much nearer globular star cluster.

X-rays stream off the Sun in this image. The NuSTAR data, seen in green and blue, reveal solar high-energy emission (green shows energies between 2 and 3 kiloelectron volts, and blue shows energies between 3 and 5 kiloelectron volts). The high-energy X-rays come from gas heated to above 3 million degrees. The red channel represents UV light captured by SDO at wavelengths of 171 angstroms, and shows the presence of lower-temperature material in the solar atmosphere at 1 million degrees. This image shows that some of the hotter emission tracked by NuSTAR is coming from different locations in the active regions and the coronal loops than the cooler emission shown in the SDO image.
