Hubble Space Telescope Captures a Sparkling Spiral Galaxy

76

This week’s picture from the Hubble House Telescope exhibits a picture-perfect galaxy, identified considerably unimaginatively as Mrk 1337. It’s positioned 120 million light-years away within the constellation of Virgo, and is a weakly barred spiral galaxy. A spiral galaxy is one like our Milky Manner, wherein “arms” of stars attain out from the busy middle of the galaxy to type a spiraling form.

This picture from the NASA/ESA Hubble House Telescope options the spiral galaxy Mrk (Markarian) 1337, which is roughly 120 million light-years away from Earth within the constellation Virgo. Mrk 1337 is a weakly barred spiral galaxy, which because the identify suggests signifies that the spiral arms radiate from a central bar of gasoline and stars. Bars happen in roughly half of spiral galaxies, together with our personal galaxy, the Milky Manner. ESA/Hubble & NASA, A. Riess et al.

And a “barred” spiral galaxy is one which contains a central bar — once more, just like the Milky Manner — which is the place mud and gasoline give start to new stars in an elongated area within the middle of the galaxy. This galaxy’s bar is just a weak one, which suggests it’s exhausting to see, however you’ll be able to see a clearer bar in photographs of different galaxies akin to Hubble’s earlier picture of galaxy NGC 7773.

“Hubble’s Huge Area Digicam three snapped Mrk 1337 at a variety of ultraviolet, seen, and infrared wavelengths, producing this richly detailed picture,” Hubble scientists write. By capturing information in several wavelengths, scientists can see completely different options of the galaxy. By trying within the infrared wavelength, for instance, telescopes can “see” warmth and establish which areas of a picture are hotter than others. And by trying within the ultraviolet wavelength, Hubble can see the illumination of hotter objects like very younger stars.

Astronomers can mix observations from the seen mild, ultraviolet, or infrared wavelengths to choose up completely different options and get a extra detailed general take a look at an object — on this case, this stunning spiral galaxy.
