NASA and ESA's Hubble Space Telescope has recently captured detailed images of multiple galaxies, providing new insights into their structures and characteristics. Among these is NGC 45, a low surface brightness galaxy located 22 million light-years away in the constellation Cetus. The telescope also imaged NGC 2146, a spiral galaxy where supernova explosions and stellar winds drive double star systems and hot gas away, with one of its dusty arms obscuring the galaxy’s center from Earth. Another notable observation includes NGC 3783, a bright barred spiral galaxy approximately 130 million light-years distant, part of a 47-member galaxy group. Hubble's Advanced Camera for Surveys revealed NGC 6684, a lenticular galaxy about 44 million light-years away in the constellation Pavo. Additional galaxies studied include NGC 247 in Cetus at 11 million light-years, NGC 3285B in Hydra at 137 million light-years, NGC 2442 in Volans at 50 million light-years with an asymmetrical shape, NGC 3596 in Leo at 90 million light-years, NGC 2283 at 45 million light-years highlighting star clusters and supernova activity, and NGC 1022, a barred spiral galaxy 65 million light-years away. The images combine multiple wavelengths, including visible light and X-rays from Chandra, to reveal features such as galactic nuclei, star clusters, gas clouds, and supernova remnants. Additionally, Hubble captured the supernova 1987A in the Large Magellanic Cloud, located 168,000 light-years away, notable for its glowing ring caused by the explosion’s shockwave interacting with expelled gas. These observations enhance understanding of galactic formation, structure, and the dynamic processes within various galaxy types across different constellations.
This image from the Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound https://t.co/4yk1J73vjc
This is Supernova 1987A, 168,000 light-years away in the Large Magellanic Cloud. Its light reached Earth on Feb 23, 1987, making it the brightest supernova seen since 1604. The 1-light-year-wide glowing ring is lit as the explosion’s shockwave strikes gas the star expelled https://t.co/HMgivoeE0p
Hubble examined NGC 45, seen here in this new HubbleFriday view. This unique galaxy is a type called a low surface brightness galaxy. Low surface brightness galaxies are fainter than the night sky itself, making them incredibly difficult to detect. Thankfully, Hubble’s sensitive https://t.co/cbwQkFGo3k
