The reddish-pink dots are baby stars deeply embedded in the cosmic cloud of gas and dust that collapsed to create the stars. Dusty disks of cosmic debris that may eventually form planets surround the infant stars. NASA's Spitzer Space Telescope took this image. Image and caption by NASA. Ch...
当足够多的这些盐在赤霞中积累时,它们形成了一种壳状物,就像沙滩上的沙子在干燥后形成脆弱的外壳,或者就像拉浓缩咖啡时留下的咖啡渣。 在新发表于《JGR Planets》杂志上的研究中,科学家们写道:“在火星上,这样的过程可以在浅层多年冻土区域自然发生,足够的盐可能在顶层积累形成一个密封层。” 与此同时,含盐蒸汽...

Venus turns in the opposite direction as Earth and most other planets. Also, its turning is very slow.In 1989, NASA used a space shuttle(航天飞机) to send its Magellan spacecraft into orbit around Venus. The European Space Agency also put a spacecraft into orbit around Venus in 2006. ...
由第三段中的“Why it's significant: Beyond being a significant milestone for Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. (重要的原因:这次飞行不仅是火星探测的一个重要milestone,还将为工程师们思考探索其他行星的新方法铺平...
