When the word nebula entered English in the early 15th century, it had nothing to do with astronomy. Arriving as nebule meaning a cloud or mist from the Latin word nebula meaning mist, which in turn came from the Proto Indo-European root word *nebh-meaning cloud, vapor, fog, moist, sky. Ancient Greek had the related word nephele, nephos which also meant cloud. When the word nebula reappeared in English it had a medical meaning for cataracts or cloudy defects in the eye. The astronomical meaning of a cloud-like patch in the night sky was first recorded around 1730. It wasn’t until the early 20th century with the advent of modern and powerful telescopes that nebula were fully understood as massive clouds of gas and dust.

The last image shows a region large approximately 10000 light-years.
The universe is quite big.

Butterfly Nebula from Upgraded Hubble
Distance: 4,000 light years away
The bright clusters and nebulae of planet Earth’s night sky are often named for flowers or insects, and NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the central star of this particular planetary nebula is exceptionally hot though — shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust. This dramatically detailed close-up of the dying star’s nebula was recorded by the upgraded Hubble Space Telescope.

Herschel Views the Milky Way
Explanation: With a 3.5 meter diameter mirror, larger than the Hubble Space Telescope, ESA’s Herschel Space Observatory explores the Universe at infrared wavelengths. Herschel is named for German-born British astronomer Frederick William Herschel who discovered infrared light over 200 years ago. Herschel’s sensitive cameras have combined to deliver this spectacular skyscape looking toward the constellation of the Southern Cross. Spanning some 2 degrees the premier, false-color, far-infrared view captures our galaxy’s cold dust clouds in extreme detail, showing a remarkable, connected maze of filaments and star-forming regions. Such observations are intended to unravel mysteries of star formation by surveying broad areas of the galactic plane.
Arp 274, also known as NGC 5679, is a system of three galaxies that appear to be partially overlapping in the image, although they may be at somewhat different distances. The spiral shapes of two of these galaxies appear mostly intact. The third galaxy (to the far left) is more compact, but shows evidence of star formation. [Read More]
