Voyager still dancing for science 2011-03-09T11:09:19Z But if we go to the distance of even Alpha Centauri, the nearest of the stars, our earth shrinks to invisibility; so that we must seek a longer base line. Astronomy: The Science of the Heavenly Bodies 2012-03-17T02:01:02.630Z Much like the sun, where magnetic sunspots appear in bunches and then all but vanish as they follow an 11-year cycle, Alpha Centauri B also demonstrates a cyclical pattern of stellar activity. The Exoplanet Next-Door: Astronomers Discover World in Nearest Star System 2012-10-17T14:15:00.470Z If Alpha Centauri is really so important, the effect of its variations, provided it has any, ought perhaps to be evident in the sun. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Even if planets and moons were found round Alpha Centauri, as envisaged by the writers of “Avatar”, they would not get glorious monikers like Polyphemus and Pandora.

Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Rockets are slow; you would die before you got back from Alpha Centauri. Accidental Flight It is certainly true that we will never know, now, whether Alpha Centauri A ever had any planets. Time Fuze He was heading, I think, only as far as Alpha Centauri. Wainer Dumusque said that he and his colleagues observed Alpha Centauri B more than 450 times over several years to get a handle on its behavior. The Exoplanet Next-Door: Astronomers Discover World in Nearest Star System 2012-10-17T14:15:00.470Z Hence Alpha Centauri causes the main maximum in Fig. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Yet we have a gigantic contribution to make ... if we are allowed to leave the Solar System for Alpha Centauri! Accidental Flight Alpha Centauri A began to brighten and spread. Time Fuze Alpha Centauri or some such place—hard grubbing labor under a blazing or meager sun, it didn't matter which. Tangle Hold The planet's tug makes a tiny contribution of about 50 centimeters per second to the velocity of Alpha Centauri B, which is currently moving about 20 kilometers per second with respect to Earth. The Exoplanet Next-Door: Astronomers Discover World in Nearest Star System 2012-10-17T14:15:00.470Z Back in the fourteenth century a period of excessive solar activity, which has already been described, culminated from 1370 to 1385, or just before the two parts of Alpha Centauri were at a minimum distance. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z But she withdrew it and then the blackness, like some obscene mouth as large as the distance from here to Alpha Centauri, swallowed him. The Graveyard of Space The ship had only been provisioned to go to Alpha Centauri, scout the system without landing on any of the planets, and return. Time Fuze "Are you also from the Alpha Centauri system, sir?" Collector's Item There's Alpha Centauri—about twenty light years away. An Empty Bottle If Alpha Centauri has an effect on the sun's atmosphere, the end of another such period would be expected not far from 1957. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z Alpha Centauri, Arcturus, Vega, anywhere we wanted to go—and I could go along! Martyr Alpha Centauri has long since faded back into its pre-blowup state, since we have far outdistanced the light from its explosion. Time Fuze No reason why his ship shouldn't stop off at Earth before it goes to Alpha Centauri. Collector's Item He pointed at the small, far from brilliant, star that lay beyond Alpha Centauri on the plates. An Empty Bottle Hence Alpha Centauri and even Sirius may be far more effective than Betelgeuse. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z The Starship isn't going to Alpha Centauri or anywhere else. Martyr For instance: with a possible error of plus or minus two seconds Alpha Centauri A began to explode the instant we came out of ultradrive! Time Fuze No reason why it should even go to Alpha Centauri at all, in fact. Collector's Item "When they do get to Mars and Venus and the planets of Alpha Centauri and Sirius and Procyon, they'll find us there, waiting for them." Fifty Per Cent Prophet The two main components of Alpha Centauri are separated by an average distance of about 2,200,000,000 miles, or somewhat less than that of Neptune from the sun. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z I could launch this model for Alpha Centauri tonight—and it would get there.
