Sample text

Mira Also known as Omicron Ceti, red giant star between 200 and 400 light-years away in the constellation Cetus. Mira is an example of a pulsating variable star. Its brightness varies on a regular cycle 332 days in length. nebula (pl. nebulae) A cloud of dust or gas in interstellar space. neutron star Extremely dense star created from exhausted nuclear fuel following the final explosion (supernova) of a massive star at the end of its life. nova explosion Explosion in a white dwarf star caused when the star takes on matter from a twin in a binary star system and reignites, leading to runaway nuclear fusion on the surface of the white dwarf.

Indeed, astronomy has always been a driver for technology. And, thanks to huge telescopes, probes and advanced computers, modern astronomers have discovered the amazing cosmic panorama described in this book. Theorists like myself lag far behind in trying to make sense of it all. But we have made progress. We can trace cosmic history back to a mysterious beginning nearly 14 billion years ago, when everything was squeezed hotter and denser than anything that can be created in a laboratory; we understand in outline how the first atoms, stars and galaxies emerged.

The name comes from the Latin word for ‘new,’ because previously invisible white dwarf stars reappear when a nova occurs and may be taken for a new star. planetary nebula A cloud of gas expelled into space by a red giant star. The term is derived from the German-born British astronomer William Herschel who, when he identified the phenomenon in 1785, thought the nebulae or clouds he viewed were similar to the ‘gas giant’ planet Uranus. Astronomers still use the term, although these nebulae form around dying stars and have no connection to planets.
