Discovered by William Herschel in 1783, NGC 3274 is a magnitude +12.8 galaxy located over 20 million light-years away in the constellation of Leo bordering on Leo Minor. The galaxy PGC 213714 is also visible on the upper right of the frame, located some 1.3 billion light-years from Earth. Image credit: ESA/Hubble & NASA, D. Calzetti.This image of the spiral galaxy NGC 3274 comes courtesy of the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3). Hubble’s WFC3 vision spreads from the ultraviolet light through to the near infrared, allowing astronomers to study a wide range of targets, from nearby star formation through to galaxies in the most remote regions of the cosmos.
This particular image combines observations gathered in five different filters, bringing together ultraviolet, visible, and infrared light to show off NGC 3274 in all its glory. As with all of the data Hubble sends back to Earth, it takes advantage of the telescope’s location in space above our planet’s distorting atmosphere. WFC3 returns clear, crisp, and detailed images time after time.
NGC 3274 is a relatively faint galaxy located over 20 million light-years away in the constellation of Leo (The Lion). The galaxy was discovered by William Herschel in 1783. The galaxy PGC 213714 is also visible on the upper right of the frame, located much further away from Earth.
Astronomers have used NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton X-ray observatory to discover an extremely luminous, variable X-ray source located outside the centre of its parent galaxy. This peculiar object could be a wandering black hole that came from a small galaxy falling into a larger one.
Despite careful searches with the Hubble and Chandra space telescopes, astronomers have been unable to find a presumed supermassive black hole at the heart of a giant galaxy.
Hubble captures a dramatic view of two galaxies, both with active galactic nuclei, interacting in a close encounter that is pulling gas, dust and entire star systems from one toward the other.
