99 & 44/100ths percent pure

Astronomers have discovered a star with almost no impurities – just hydrogen and helium (and faint traces of calcium) – very unusual! Shouldn’t exist because mass is too low to have coalesced to form in the first place. Very primitive because amt of metals tells how old the star is. Japanese ready to test space junk cleaner; The idea -metal strands attached to dead satellites that will generate electricity as they drag through magnetic field, creates drag pulling satellite into a lower orbit (now 500 – 900 miles up; 20,000 objects). Planets great in the morning sky!
