Hubble Space Telescope Seeing the Upper Edge Spiral Galaxy | astronomy



NASA / ESA’s Hubble space telescope has created a striking image of a spiral galaxy called UGCA 193.

UGCA 193 is located about 32 million light-years away in the constellation Sextans.

Also known as FGC 998 or LEDA 29086, this galaxy is a member of the NGC 31

15 group, a small subset of a number of galaxies of different shapes and colors.

“Looking like a waterfall, the UGCA 193 seems to contain many young stars, especially in its lower part, creating a striking blue cloud and the feeling that the stars are falling from above, “Hubble astronomers said.

“The blue color of UGCA 193 indicates that the stars we see are hot – some are six times higher than our sun.”

They added: “We know that colder stars look redder and warmer stars appear more blue.

“When a star’s mass and surface temperature, and therefore its color, are linked together, heavier stars can burn at higher temperatures resulting in blue light from the surface. of them.”

The new UGCA 193 image is generated from the observations from Hubble’s Advanced Survey Camera (ACS) in the near infrared and optical parts of the spectrum.

It is based on data obtained through two filters: the wide V filter (F606W) and the red filter (F814W).

Color is the result of assigning different colors to each monochrome image associated with an individual filter.
