NGC 2903 is an isolated barred spiral galaxy in the equatorial constellation of Leo, positioned about 1.5° due south of Lambda Leonis. [10] It was discovered by German-born astronomer William Herschel, who cataloged it on November 16, 1784.

NGC 2903 is a Spiral Galaxy in the Leo constellation. NGC 2903 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its visual magnitude of 9.07, NGC 2903 is visible with the help of a binocular with a 60-70mm aperture or a small telescope.

2023年3月15日 · Many observers propose that NGC 2903, a superb spiral galaxy in Leo that’s a major highlight of the spring sky, fits the bill, matching up well to marvellous Messier 66 (NGC 3627) or indeed any of the other galaxies, Messier-designated or otherwise, found in Leo.

One of the brighter galaxies visible from the northern hemisphere, NGC 2903 is surprisingly missing from Charles Messier's catalog of lustrous celestial sights. This colorful image from a small ground-based telescope shows off the galaxy's gorgeous spiral arms traced by young, blue star clusters and pinkish star forming regions.

The galaxy NGC 2903 is located about 1.5° south of the star λ Leonis in the constellation Leo. The best observation time is September to June.

A perfect object to start late each evening (2 AM to 5 AM) after capturing Abell 370. I was able to use the same camera settings with no overexposure. The ASI6200 (Sony IMX455 CMOS) is amazingly conf...

2019年5月3日 · In fact, this image from Hubble frames a perfect spiral specimen: the stunning NGC 2903. NGC 2903 is located about 30 million light-years away in the constellation of Leo (the Lion), and was studied as part of a Hubble survey of the central regions of …

2023年2月5日 · NGC 2903 is a barred spiral galaxy in Leo 30 million light years away. Imaged by Canadian astrophotographer Ron Brecher from Guelph, Ontario.

Explanation: NGC 2903 is a spiral galaxy similar to our own Milky Way Galaxy. Similarities include its general size and a central bar. One striking difference, however, is the appearance of mysterious hot spots in NGC 2903's core.

In fact, NGC 2903 exhibits an exceptional rate of star formation activity near its center, also bright in radio, infrared, ultraviolet, and x-ray bands. Just a little smaller than our own Milky Way, NGC 2903 is about 80,000 light-years across.
