On Monday, Saturn will officially reach opposition, meaning that it will appear opposite of the sun from the perspective of the Earth. Saturn is at opposition once every year. Around the same time of opposition, Saturn will make its closest approach to the Earth, although "close" is a relative term as more than 800 million miles will still separate the two planets. At this distance, it takes light more than one hour to travel from one planet to...

Satellite constellations could hinder astronomical research, scientists warn

Aug. 25 (UPI) -- SpaceX has so far sent a few hundred of Starlink broadband satellites into orbit, but the aerospace company has plans for a constellation featuring thousands of small satellites -- and this has researchers concerned. A report published Tuesday by the Satellite Constellations 1 workshop, an effort organized by the National Science Foundation and the American Astronomical Society, says the constellation could be bad news for astronomers and their research. Advertisement "The main takeaway from our findings is that no combination of mitigations will totally eliminate the impacts of satellite constellations on ground-based astronomy," Connie Walker, an astronomer with NSF's NOIRLab and co-chair of the SATCON1 workshop, told reporters during a virtual press conference on Tuesd...
