Hubble grabs the Spiral Galaxy profile – From the Hydra constellation 80 million light-years away



  Spiral Galaxy NGC 3717

The NASA / ESA Hubble Space Telescope sees galaxies of all shapes, sizes, magnitudes, and orientations in the cosmos. Sometimes the telescope looks at a sideward galaxy ̵

1; as shown here. The spiral galaxy shown in this Hubble image is called NGC 3717 and is located about 80 million light-years away in the constellation Hydra (the Sea Serpent).

A spiral almost in profile to see how Hubble did it here. can convey a vivid impression of its three-dimensional shape. Spiral galaxies are shaped like a thin pancake over most of their extent. In their nuclei, however, they have bright, spherical, star-shaped bulges that extend above and below this disc and give these galaxies the shape of a flying saucer when viewed from above.

NGC 3717 is not perfectly captured in this image; The nearer part of the galaxy is slightly inclined downwards and the other side is tilted upwards. This angle allows a view of the disc and the central bulge (of which only one side is visible).

Notes:

NGC 3717 is a spiral galaxy Located in the constellation Hydra at a distance of approximately 81.43 million light-years. NGC 3717 was discovered in 1834 by Sir John Herschel.

Hydra is the largest of the 88 modern constellations, measuring 1303 square degrees and the longest at over 100 degrees. Its southern end borders on Libra and Centaurus and its northern end borders on Cancer. It belonged to the 48 constellations of the astronomer Ptolemy from the 2nd century. It is commonly represented as a water snake. It is located in the southern hemisphere.
