Henize 2-10

A dwarf starburst galaxy about 30 million light years from Earth.Henize 2-10 is a dwarf galaxy, and it is the first dwarf galaxy ever discovered to contain a supermassive black hole at its center. This was surprising because the black hole is about one quarter of the size of the one at the center of the Milky Way Galaxy. However, Henize 2-10 is only about1/1,000th the size of the Milky Way..

This image combines x-ray (Chandra), visible light (Hubble), and radio telescope (Very Large Array) views.

M82 on the Radio

m82_gbtThis composite image of starburst galaxy M82 shows the distribution of dense molecular gas as seen by the National Radio Astronomy Observatory’s 85-ft Green Bank Telescope (yellow and red) and the background stars and dust as seen by Hubble (blue). The yellow areas correspond to regions of intense star formation. The red areas trace outflows of gas from the disk of the galaxy.

A Tempest in the Teacup

Storm in a TeacupIn this composite image of the Teacup Galaxy (aka SDSS 1430+13) the visible light from stars is shown in green, the IR emissions from gas and dust cloud are shown in blue, and the red/yellow colors show the radio emission. The bright yellow blobs in the center of the image show where the radio “jets” emitted by the central black hole are driving into the gas and pushing outward at 1,000 km/s. The central black hole is having a catastrophic effect on this galaxy.
