The NASA/ESA Hubble Space Telescope took this photo of barred spiral galaxy NGC 337.

NGC337 It is located in the constellation Cetus, approximately 60 million light-years from Earth.
Also known as LEDA 3572 or IRAS 00573-0750, this barred spiral galaxy is 60,400 light years in diameter.
it was discovered It was discovered on September 10, 1785 by German-British astronomer William Herschel.
NGC 337 is the largest and brightest member of the NGC 337 Group (also known as LGG 15), a small group that includes at least three other galaxies.
The new images of the galaxy were created from separate exposures taken in the visible and near-infrared regions of the spectrum. Hubble’s advanced survey camera (ACS).
Two filters were used to sample different wavelengths. Color is obtained by assigning different hues to each monochromatic image associated with an individual filter.
“This image combines observations made at two wavelengths and highlights the galaxy’s golden center and blue surround,” Hubble astronomers said in a statement.
“The golden glow in the center comes from the older star, and the glowing blue edge gets its color from the young star.”
“If Hubble had observed NGC 337 about a decade ago, the telescope would have spotted something remarkable among the hot blue stars along the edge of the galaxy: a brilliant supernova,” they added. Ta.
“Labeled SN2014cxthis supernova is notable in that it was discovered almost simultaneously by two very different methods: the prolific supernova hunter Koichi Itagaki and the All-Sky Automated Supernova Surveyor (ASAS-SN). ”
“ASAS-SN is a worldwide network of robotic telescopes that scan the sky for sudden events such as supernovae.”
According to astronomers, SN 2014cx IIP type supernova.
“The Type II classification means that the star that exploded was a supergiant with a mass at least eight times that of the Sun,” the researchers said.
“The ‘P’ stands for plateau, meaning that after the light from the supernova began to dim, the level reached a plateau and remained the same brightness for weeks or months before fading further. .”
“This type of supernova occurs when a massive star can no longer generate enough energy at its core to avoid the crushing pressure of gravity.”
“The progenitor star of SN 2014cx is estimated to have been 10 times more massive and hundreds of times wider than the Sun.”
Although it has long since dimmed from its early brightness, astronomers are still monitoring the remains of SN 2014cx.
