Hubble Captures Image of Active Spiral Galaxy NGC 7456

Using the Widefield Camera 3 (WFC3) mounted on the NASA/ESA Hubble Space Telescope, astronomers have captured a breathtaking new image of the Spiral Galaxy NGC 7456.

NGC 7456 was discovered by British astronomer John Herschel on September 4, 1834.

This galaxy is approximately 51 million light-years from Earth, in the constellation Grus.

Also referred to as ESO 346-26, IRAS 22594-3950, or LEDA 70304, it spans a diameter of 117,100 light-years.

The NGC 7456 belongs to the LDC 1547 Galaxy Group, which includes 16 large galaxies.

“In Hubble’s image, one can observe the intricate, swirling arms of this galaxy in exquisite detail, complemented by a dark, diffuse mass of dust,” remarked an astronomer from Webb.

“The bright pink regions signify gas-rich areas where new stars are emerging, illuminating the surrounding clouds, as this gas emits transmitted red light.”

“The Hubble program has been gathering these data to study stellar activity, tracking new star-forming clouds, hydrogen, star clusters, and gaining insights into galaxy evolution over time,” they further explained.

“With its capability to capture visible ultraviolet and some infrared light, Hubble isn’t the only observatory focused on NGC 7456.”

“ESA’s XMM-Newton satellite has imaged X-rays from galaxies multiple times and discovered what is known as a hyper-luminous X-ray source.”

“These compact objects emit significantly more powerful X-rays than one would expect for their size.”

“We are still investigating what drives these extreme objects. NGC 7456 contributes several examples to this research.”

“Additionally, the area surrounding the galaxy’s supermassive black hole is incredibly bright and energetic, making NGC 7456 an active galaxy.”

“Whether viewed in visible light or X-rays, there’s always something intriguing about this galaxy, whether focusing on its core or its outer regions.”
