根据该论文的作者Olivier Hainaut和Andrew Williams的说法,私人卫星将在天文学领域产生不同的影响。幸运的是,当更多的卫星将反射升起或落下的太阳光时,在晚上的头几个小时和最后一个小时的工作受到的影响最大,因此这方面的影响几乎可以忽略不计。
他们还发现,卫星的耀斑和掩星对观测的影响很小。他们发现,在夜晚的头几个小时和最后几个小时,使用正常的视场成像,可见光和近红外光谱望远镜技术时,卫星光迹将破坏大约1%的望远镜曝光。
受影响更大的是广角曝光和中度长时间曝光,在夜晚的头一个小时和最后一个小时,大约3%的时间会受到影响。最大的影响将是通过超大型望远镜(如维拉鲁宾天文台)完成的超宽成像曝光。在夜晚的头一个小时和最后一个小时内,有30%到40%的曝光会受到影响,为了减轻这些问题,研究人员建议天文学界,卫星公司和政府机构进行协调与协作以解决相关问题。
