P7.4.27 recall that in a white dwarf star there is NA NA no nuclear fusion; the star gradually cools and fades P7.4.28 recall that in a high-mass star (several NA NA times the mass of the Sun) nuclear fusion can produce heavier nuclei up to and including iron; when the core is mostly iron, it explodes as a supernova creating nuclei with masses greater than iron and leaving a dense neutron star or a black hole. P7.4.29 understand that astronomers have found NA NA convincing evidence of planets around hundreds of nearby stars P7.4.30 understand that, if even a small NA NA proportion of stars have planets, many scientists think that it is likely that life exists elsewhere in the Universe P7.4.31 recall that no evidence of extraterrestrial NA NA life (at present or in the past) has so far been detected. P7.5.1 recall that major optical and infrared NA NA astronomical observatories on Earth are mostly situated in Chile, Hawaii, Australia and the Canary Islands P7.5.2 describe factors that influence the NA NA choice of site for major astronomical observatories including: a. high elevation b. frequent cloudless nights c. low atmospheric pollution and dry air d. sufficient distance from built up areas that cause light pollution P7.5.3 describe ways in which astronomers NA NA work with local or remote telescopes P7.5.4 explain the advantages of computer NA NA control of telescopes including: a. being able to work remotely b. continuous tracking of objects c. more precise positioning of the telescope d. computer recording and processing of data collected
