We present the photometric analysis of six short-period systems (EI Oct, V336 TrA, NX Boo, V356 Boo, PS Boo, and V2282 Cyg). This is the first photometric analysis of these systems except for V336 TrA ...

In this historical photo from the U.S. space agency, a view of the area at Station 4 (Shorty Crater) showing the highly-publicized orange soil which the Apollo 17 crewmen found on the Moon during the ...
