The two ends of the nebula are marked by FLIERs, lobes of fast moving gas often tinted red in false-color pictures. [5] NGC 3242 can easily be observed with amateur telescopes and appears bluish-green to most observers. Larger telescopes can distinguish the outer halo as well. [6] At the center of NGC 3242 is an O-type star with a spectral type ...
The Hubble Deep Field (HDF) is an image of a small region in the constellation Ursa Major, constructed from a series of observations by the Hubble Space Telescope. It covers an area about 2.6 arcminutes on a side, about one 24-millionth of the whole sky, which is equivalent in angular size to a tennis ball at a distance of 100 metres. [ 1 ]
NGC 5495 is a very large barred spiral galaxy located in the constellation Hydra. [1] [2] Its speed relative to the cosmic microwave background is 6,989 ± 20 km/s, which corresponds to a Hubble distance of 103.1 ± 7.2 Mpc (∼336 million ly). [3] [4] NGC 5495 was discovered by British astronomer John Herschel in 1834.
The Hubble Space Telescope (HST) is one of the most well-known telescopes in the world and is responsible for iconic images of space featured in textbooks and publications around the globe.
Insider went through the archives of three NASA observatories — JWST, Hubble, and Chandra X-ray — to find the most iconic pictures of space.
The first deep-field image to receive a great deal of public attention was the Hubble Deep Field, observed in 1995 with the WFPC2 camera on the Hubble Space Telescope. Other space telescopes that have obtained deep-field observations include the Chandra X-ray Observatory , the XMM-Newton Observatory, the Spitzer Space Telescope , and the James ...
NGC 3052 is an intermediate spiral galaxy in the constellation of Hydra.Its velocity with respect to the cosmic microwave background is 4122 ± 24 km/s, which corresponds to a Hubble distance of 60.79 ± 4.27 Mpc (∼198 million light-years). [1]
NGC 2935 is a large intermediate spiral galaxy located in the constellation Hydra. Its speed relative to the cosmic microwave background is 2,601 ± 23 km/s, which corresponds to a Hubble distance of 38.4 ± 2.7 Mpc (~125 million ly). It was discovered by German-British astronomer William Herschel on 20 March 1786.
