Hubble Image of a Week – Megamaser IRAS 16399-0937

Megamaser IRAS 16399-0937

This newly expelled Hubble picture shows megamaser IRAS 16399-0937, that is located over 370 million light-years away.

This universe has a distant some-more sparkling and unconventional sequence than many — it is a megamaser. Megamasers are greatly bright, around 100 million times brighter than a masers found in galaxies like a Milky Way. The whole universe radically acts as an astronomical laser that beams out x-ray glimmer rather than manifest light (hence a ‘m’ replacing a ‘l’).

This megamaser is named IRAS 16399-0937, and is located over 370 million light-years from Earth. This NASA/ESA Hubble Space Telescope picture belies a galaxy’s enterprising nature, instead portrayal it as a pleasing and relaxed vast rosebud. The picture comprises observations prisoner opposite several wavelengths by dual of Hubble’s instruments: a Advanced Camera for Surveys (ACS), and a Near Infrared Camera and Multi-Object Spectrometer (NICMOS).

NICMOS’s glorious sensitivity, resolution, and margin of perspective gave astronomers a singular event to observe a structure of IRAS 16399-0937 in detail. They found that IRAS 16399-0937 hosts a double iota — a galaxy’s core is suspicion to be shaped of dual detached cores in a routine of merging. The dual components, named IRAS 16399N and IRAS 16399S for a northern and southern tools respectively, lay over 11 000 light-years apart. However, they are both buried low within a same whirl of vast gas and dirt and are interacting, giving a universe a rare structure.

The nuclei are really different. IRAS 16399S appears to be a starburst region, where new stars are combining during an implausible rate. IRAS 16399N, however, is something famous as a LINER iota (Low Ionization Nuclear Emission Region), that is a segment whose glimmer mostly stems from weakly-ionised or neutral atoms of sold gases. The northern iota also hosts a black hole with some 100 million times a mass of a Sun!
