半人马座α星(Alpha Centauri),是距离太阳最近的三星系统。 2008年5月17日,卡西尼号的窄角相机在可见光下拍摄到了它的身影,悬挂在土星地平线上的半人马座α星A和半人马座α星B,清晰可见,当时卡西尼相距土星...
距离Sol旁边还有半人马座阿尔法星系(Alpha Centauri),或者说南门二,在现实中离太阳最近的恒星系。 实际演示展示了一批行星的场景描绘,其中一个行星黄沙乌云覆天的场景就像火星,一辆火星探测车出现在画面中央。 经Reddit这辆车的原型是美国航空航天局(NASA)设计的“勇气号”(Spirit),火星于2004年登陆,在失去联系之前努...
NASA dreams of Alpha Centauri tripIF A small, scrappy group at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, get their way, the 100th anniversary of Apollo ll - the first crewed moon landing -will see a spacecraft launched to a nearby exoplanet to look for life....
byNASA Credit: ESA/NASA The closest star system to the Earth is the famous Alpha Centauri group. Located in the constellation of Centaurus (The Centaur), at a distance of 4.3 light-years, this system is made up of the binary formed by the stars Alpha Centauri A and Alpha Centauri B, p...
That's the goal of a project calledBreakthrough Starshot— the brainchild of a Russian billionaire, a former director ofNASA's Ames Research Center and a group of high-level physicists and engineers. They hope to send hundreds of tiny spacecraft to the Alpha Centauri star system, where they...
Credit: Optical: Zdenek Bardon; X-ray: NASA / CXC / Univ. of Colorado / T. Ayres et al. Key Takeaways Our neighboring solar system is an odd one by any measure. It’s a triple system consisting of Alpha Centauri A and B and Proxima Centauri. ...
The Alpha Centauri system actually consists of three stars — the red dwarf Proxima Centauri and the binary group of Alpha Centauri A and B, which orbit each other in a cosmic dance. Last month we discovered an Earth-sized exoplanet,Proxima Centauri b, which orbits Proxima Centauri, but the...
Hopefully the telescope will find a planet in the habitable zone that Breakthrough Starshot can target for an interstellar mission.
An altered future was created where the more inhumane wars of the 21st century left Earth a pre-warp civilization that never even expanded to the solar system. Consequently, the Romulan Star Empire had expanded to include Alpha Centauri. (DS9: "Past Tense, Part I", "Past Tense, Part II...
Alpha Centauri stands as the closest known stellar system to our Solar System at a distance of 1.34 pc away from Earth [1]. As such, it constitutes a target of choice for numerous studies related to stellar and orbit characterisation, e.g., [2,3,4]. This system is composed of three ...
