英国物理学家马克是谢菲尔德大学物理学研究所的成员。他们这个研究小组发明出用3D技术打印的天文望远镜,费用大约为650美元。在观测条件良好的夜晚,用这种望远镜可以看到宇宙中的星系、恒星团,甚至是太阳系内的行星等天体。这对业余天文爱好者无疑是个好消息,可以大大降低天文观测的成本。 Mark, a British physicist, is a member of the Institute of Physics at the University of Sheffield. Their team invented the astronomical telescope printed with 3D technology for about $ 650. In the evening with good observation conditions, you can see the galaxy, the cluster of stars and even the planets in the solar system by using this telescope. This is undoubtedly good news for amateur astronomy enthusiasts and can significantly reduce the cost of astronomical observations.
