![]() Hubble’s observations also paved the way for future instruments M74 was one of the first targets of the powerful new NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope.Ĭredit: European Space Agency (ESA)/Hubble & NASA, R. Combining observations of the same object from different telescopes across the electromagnetic spectrum gives astronomers far more insight than observations from a single telescope would. ![]() They also explored the distribution of dust in spiral galaxies this dust is visible in this image as the dark threads winding along the spiral arms of M74.Īside from their quest to understand the history of spiral galaxies, astronomers also observed M74 to complement observations from other telescopes. To do this astronomers examined star clusters to date the different parts of spiral galaxies, enabling them to understand how the galaxies assembled over time. Spirals are characterized by circular symmetry, a bright nucleus surrounded by a thin outer disk, and a superimposed spiral structure. galaxies are labeled by their redshifts as indicated in Table I refer. The data in this image come from a set of observations exploring the evolution of local spiral galaxies such as M74, which aim to gain insights into the history of star formation in these spirals. whether the underlying galaxies are spirals (as in most nearby Seyfert galaxies). Hubble’s Advanced Camera for Surveys, which collected the data in this image, even has a filter designed to pick out only this specific red wavelength of light! Bright knots of glowing gas light up the spiral arms, indicating a rich environment of star formation. These regions,which astronomers refer to as H II regions, mark the location of recent star formation and are an important target for both space- and ground-based telescopes. Resembling festive lights on a holiday wreath, this NASA/ESA Hubble Space Telescope image of the nearby spiral galaxy M74 is an iconic reminder of the impending season. 3 4 It was discovered by John Herschel in 1835. It is a member of the Eridanus Cluster, a cluster of 200 galaxies. The galaxy is about 110,000 light-years across. Bright knots of glowing gas light up the spiral arms, indicating a rich environment of star formation. MCG-03-09-018, 1 ESO 547 -G 31, 2, 1 UGCA 066 is a barred spiral galaxy located about 61 million light-years away in the constellation Eridanus. The galaxy has an apparent magnitude of 14.73 and lies at an approximate distance of. With a radius of about 2 million light years and home to 100 trillion stars, it is one of the largest galaxies known, as well as one of the most luminous. The beautiful reddish blooms that spread throughout M74 are huge clouds of hydrogen gas which are made to glow by the ultraviolet radiation from hot, young stars embedded within them. Spiral Galaxy Resembling festive lights on a holiday wreath, this NASA/ESA Hubble Space Telescope image of the nearby spiral galaxy M74 is an iconic reminder of the impending season. IC 1101 is a supergiant elliptical galaxy located in the constellation Virgo. ![]() M74-also known as the Phantom Galaxy-lies around 32 million light-years away from Earth in the constellation Pisces, and is a familiar sight for Hubble. The arms of the spiral galaxy M74 are studded with rosy pink regions of fresh star formation in this image from the NASA/European Space Agency Hubble Space Telescope.
