A clickable map of the nearby circa one-sixth outer sector of the galaxy, thus clearly showing the Local Arm (Orion Arm) and neighboring arms - as well as the Great Orion Nebula (as a very luminous feature of the less bright Orion molecular cloud complex) and broad-clouds North America Nebula (and Pelican Nebula) which is an intrinsic part of the Radcliffe wave.
A GALEX image of the spiral galaxy Messier 81 in ultraviolet light. Credit:GALEX/ NASA / JPL - Caltech . Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres ; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma-ray ...
The star emits pulses of radiation from gamma rays to radio waves. At X-ray and gamma ray energies above 30 keV, the Crab Nebula is generally the brightest persistent gamma-ray source in the sky, with measured flux extending to above 10 TeV. The nebula's radiation allows detailed study of celestial bodies that occult it.
We may never be rich enough to afford a trip into space, but that doesn't mean we can't gaze longingly at it from afar.Here to facilitate some intergalactic contemplation is the shortlist for the ...
The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun, observed from Earth, stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.
The Sun is currently 5–30 parsecs (16–98 ly) above, or north of, the central plane of the Galactic disk. [104] The distance between the local arm and the next arm out, the Perseus Arm, is about 2,000 parsecs (6,500 ly). [105] The Sun, and thus the Solar System, is located in the Milky Way's galactic habitable zone. [106] [107]
An analysis of NGC 1068's spectra using Interferometry by Tacconi et al. (1994) suggested that the galaxy's Seyfert 1 core was obstructed by a thick Molecular cloud region. [17] M77 Type II Supernova, November 2018. X-ray source 1H 0244+001 in Cetus has been identified as Messier 77. [18] Only one supernova has been detected in Messier 77. The ...
NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. [3] The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster.
