- The molecules may well have existed in the primeval nebula from which the bodies of the Solar System formed, about 4.5 x 109 years ago.
- Using the 100-inch telescope on Mount Wilson, in 1923 Hubble identified for the first time a cepheid variable star in a spiral "nebula" (M 31 in Andromeda), and proceeded in the next few years to make similar discoveries in several other such "nebulae".
- The detailed maps show dozens of dust clouds - the most intense being around the great Tarantula Nebula, where thousands of stars are currently being born.
- Opposite page : Drawing of a gaseous nebula taken from a photograph published by the Lick Observatory, contrasted with an impression of a hand.
- Eventually, according to Laplace, v increased so much that centrifugal force at the edge of the nebula overcame the gravitational force exerted by the mass, and a ring of material broke away.
- One proposed explanation was a supernova explosion near the Solar System as it was forming, injecting a large quantity of carbon-16 into the pre-solar nebula and thus skewing the oxygen-isotope concentrations in carbonaceous chondrites.
- In our Galaxy, these include young massive stars, newly-formed pulsars (like the famous Crab Pulsar in the Crab Nebula), and streams of gas in double-star systems where matter is falling from one star onto a compact star - a neutron star or black hole.
- The problem, however, was that not enough of the gaseous nebula could in fact have broken away from the embryonic sun, as later generations of astronomers were quick to point out.
- These red giants were probably close neighbours of the infant sun and the ejected matter fell into the solar nebula.
- An evening of lively songs and tunes with TAP THE KEG NEBULA
- One night he detected a faint comet, went inside to check a star map to ensure there was no nebula in that position, but was unable to see it again when he went back outside.
- The great nebula of Andromeda, was a misty smudge in the belt of Orion lying on the jagged edge of High Possil.
- Direct-injection diesels can be converted to gas operation using the Nebula piston (right), which concentrates existing swirl in an open chamber for low NOx-output combustion.
