  Example sentencesExamples
  The colours of unreachable nebulas mingled with the darkness and desolation of space.
  A number had been discovered in deep space, but to an ordinary telescope each nebula looked like a faint blur; it was difficult to determine whether it was a cloud of gas or a multitude of stars.
  We sometimes use the word nebula to refer to galaxies, various types of star clusters, and various kinds of interstellar dust or gas clouds.
  Hubble realized that these spiral nebulae were so far away they were actually galaxies - separate cities of stars - far beyond our own Milky Way.
  More distant nebulae and galaxies require longer exposure times, and more fiddling.
  In further studies, he showed that these nebulas are actually other galaxies, and he went on to classify them.
  The large globe with clustered nebulas and speckled stars and solar systems that were scattered with planets, suns and moons rotated slowly and gently.
  Originally, the word nebula referred to almost any extended astronomical object (other than planets and comets).
  Stars, as far as the eye can see, and two of them, pretty close, with a string of planets orbiting between them, the whole family swimming in a pink, blue, and purple nebula.
  But soon, performing a visual diminuendo, they drift well astern, a distant nebula of glittering pinpoints at the planet's indistinguishable edge.
  One of the nicest sectors I ever saw is Ocean of Fantasy, a sector rounded by a bright green nebula.
  In early 1845, before his telescope was completed, Rosse had resolved his first nebula, discovering it to be a spiral galaxy of stars.
  Smudges like this are called nebulae, because they look nebulous - like hazy clouds.
  Heber Curtis had been correct in the 1920 debate; many of the nebulae were indeed remote galaxies.
  I can see the stars outside, the swirling patterns of distant nebulae.
  It was only in the 1920's that the American astronomer Hubble established that some of these nebulae were indeed distant galaxies comparable in size to our own Milky Way.
  Then Edward Hubble discovered that the nebulae were other galaxies like ours only much further away than was thought possible.
  The picture has widened and deepened ever since; fuzzy nebulae were revealed to be other galaxies, as full of stars as our own, and the chemistry of the stars yielded to spectrum analysis.
  Then if he'd looked farther, deeper, he saw star systems, colorful nebulas never before seen in his dreams.
  It is a nebulae system, planets and stars bobbing in and out of blue, purple, and pink stardust.
  Hubble's discovery showed that spiral nebulae are entire systems of stars in their own right, as huge and as packed with stars as our own Milky Way.
  Synonyms
  star system, solar system, constellation, cluster
2Medicine
A clouded spot on the cornea causing defective vision.
〔医〕薄翳，角膜云翳
Example sentencesExamples
- The bruise over his eye had settled in to a purple nearly matching the nebula itself, but the swelling had reduced dramatically.
- It treats conjunctivitis, pterygium, nebula and pain in the eyes.

Origin

Mid 17th century (as a medical term): from Latin, literally 'mist'.
