As an astronaut traverses the lunar South Pole, tribocharging from walking on the lunar surface and plasma charging from the ambient plasma generate electric charge on the spacesuit. This problem is severely compounded when entering lunar shadows and Permanently Shadowed Regions (PSRs). In these dark zones, the spacesuit can buildup a substantial negative potential due […]

Astronomers Solve Cosmic Cold Case with NASA Hubble Data
Diligent sleuthing by astronomers uncovered a surprising chemical clue that indicates the white dwarf star HS 0209+0832 may host a second-generation planet. This artist’s concept released on Oct. 5, 2026, depicts that possible explanation. The white dwarf is the “dead” core of a star that burned through all of its nuclear fuel and lost its outer […]
