Scientists used an instrument called the noble Accuracy Radial fastness Planet Searcher. HARPS, located at the European Southern Observatorys La Silla Observatory in Chile, searches for planets away(p) our solar system using a radial velocity method.
Heres how that works: When a planet arenas a corpus, the hint wobbles back and forth s slackly because of the planets gravitational force. Scientists are looking at how fast the star is moving toward or away from Earth. They measure this through the wavelength of the light from the star, which gets shifted if at that places a planet present (similar to the Doppler effect).
The new planet is unlikely to harbor life, or at least life as we know it, Dumusque said.
Its located passing close to its parent star Earth has a 365-day orbit around our sun, and this other planet orbits its star in precisely three days. Temperatures on the surface could be in the body politic of 1300 degrees Fahrenheit, scientists estimate. Rather than solid, the surface is likely to be lava.
But there is hope for life in that neighborhood: Small-mass planets like the cardinal orbiting alpha Centauri B are usually not entirely with their sun, Dumusque said. Often there are other planets in the system, far away from the parent star.
The next tone would be to go forward monitoring the shifts in light from the star, looking for other planets. date is of the essence, however: As Alpha Centauri B and another star, Alpha Centauri A, move closer to each other, finding any planets in the area will become more difficult. Proxima Centauri, the closest star to Earth besides the sun, may be related to this double star system.
When a planet similar to the Earth is detected, the next step is to start characterizing its atmosphere, looking for elements such as carbon and...If you compliments to get a full essay, order it on our website: Ordercustompaper.com
