The boosted exposure to cosmic rays from supernovae could have had «substantial effects on
the terrestrial atmosphere and biota,» the authors write.
He was thus the first to understand that
the terrestrial atmosphere absorbs some part of the infrared light coming from space.
Knowing that
the terrestrial atmosphere absorbs some of the infrared rays coming from space, astronomers (both amateurs and professionals) began to collect airborne data beginning in the 1930's.
3) All ground - based telescopes must observe through
the terrestrial atmosphere.
Hubble, about as big and heavy as a school bus but a lot faster — it orbits some 350 miles above Earth at 17,500 miles per hour — is much more than a swiftly careening camera, and it gets much better resolution than earthbound telescopes because there's
no terrestrial atmosphere in the way.
Of course, permissivity values used in practical design work here on Earth take into account the gases of
the terrestrial atmosphere.
