NGC 3147 is a spiral galaxy located in the constellation Draco. It is located at a distance of about 130 million light years from Earth, which, given its apparent dimensions, means that NGC 3147 is about 140,000 light years across.

2019年7月11日 · The graceful, winding arms of the majestic spiral galaxy NGC 3147 appear like a grand spiral staircase sweeping through space in this Hubble Space Telescope image. They are actually long lanes of young blue stars, pinkish nebulas, and dust in silhouette.

2019年7月11日 · The Hubble image shows off the galaxy's sweeping spiral arms, full of young blue stars, pinkish nebulas, and dust in silhouette. However, at the brilliant core of NGC 3147 lurks a monster black hole, weighing about 250 million times the mass of our Sun. Hubble observations of the black hole demonstrate two of Einstein’s theories of relativity.

2023年8月10日 · NGC 3147 is a spiral galaxy 130 million light-years away from Earth. Hubble’s clear view of the cosmos enables it to capture details like the clusters of young blue stars, pinkish nebulas and lanes of dust visible in the galaxy’s graceful, winding arms.

2019年7月11日 · The shape and structure of this Spiral galaxy are plainly visible thanks to this perspective. Galaxy NGC 3147 galaxy is relatively close by, at a distance of roughly 130 million light-years, and can be found in the constellation of Draco (The Dragon). Credit:

NGC 3147是位于天龙座的一个星系。 它的赤经为 1016.9，赤纬为 73° 24′，大小 4′。

NGC 3147 is a Seyfert 2 Galaxy located in the constellation of Draco in the northern hemisphere. NGC 3147's distance from Earth is 129,200,325.90 light years. NGC 3147 is called NGC 3147 in the New General Catalogue (NGC).

2022年9月5日 · A previous narrow-slit ( 0.1 arcsec) Hubble Space Telescope observation unveiled a broad relativistic H α profile in NGC3147, a low-luminosity ( Lbol ∼ 1042 erg s −1 ), low-Eddington ratio ( Lbol/LEdd ∼ 10−4) active galactic nucleus (AGN), formerly believed to be a candidate true type 2 AGN intrinsically lacking the broad-line region.

2019年7月11日 · A Hubble Space Telescope image of the spiral galaxy NGC 3147 appears next to an artist's illustration of the supermassive black hole residing at the galaxy’s core. The Hubble image shows off the galaxy's sweeping spiral arms, full of …
