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.
For the first time, the Hubble Space Telescope has photographed the surviving companion of a star that exploded in a supernova blast 17 years ago, evidence that supernovas can originate in binary star systems.
Observers in Western Europe should look to the east an hour before sunrise on Monday, 18 September to see not only dazzling Venus and the old crescent Moon in the same binocular field of view, but planets Mars and Mercury against the stars of Leo too.
For the first time astronomers were able to analyse the atmosphere of a super-Earth exoplanet. Using data gathered with the Hubble Space Telescope and new analysis techniques, the exoplanet 55 Cancri e some 40 light-years away is revealed to have an atmosphere consists mainly of hydrogen and helium without any indications of water vapour.
