Both of these are the record for the largest total number of spacewalks by a male and a female, and the most cumulative time spent on spacewalks by a male and a female. Man – Anatoly Solovyev, 16 spacewalks for a total time of 82 hours, 21 minutes. [44] Woman (number) – Peggy Whitson, 10 spacewalks for a total time of 60 hours, 21 minutes.
PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.
This encounter shortened its period to half of that of Venus, or about 112.5 days. After two orbits it met Venus a fourth time at about the same place, shortening its period to about 102 days. [58] After 237 days, it met Venus for the fifth time and its period was shortened to about 96 days, three-sevenths that of Venus.
However, because the expansion of the universe is accelerating, it is projected that most galaxies will eventually cross a type of cosmological event horizon where any light they emit past that point will never be able to reach us at any time in the infinite future, [21] because the light never reaches a point where its "peculiar velocity ...
These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe.
