    Blog 69: Landing on Mars
    Around three dozen visitors were scattered throughout a University of Utah auditorium Monday witnessing first-hand one of NASA's greatest triumphs, the descent and landing of the InSight Mars probe. The program was hosted by the U.'s Department of Physics and Astronomy and its South Physics Observatory. Some sat with laptops or notebooks; some checked out displays about physics and space, which had been set up at the entrance and at the front of the auditorium; others stood chatting. The voice

In 1950, he and three other scientists were chatting about the possibility of advanced alien civilizations when he asked something like, "Where is everybody?" The question has come to be known as the Fermi Paradox, the most famous query about extraterrestrial civilizations, one that is recited and argued

    Blog 66: Comets, Part 2
    Of the comets I've seen, no two were alike, ranging from a monster that, counting its coma of particles, was the biggest thing in the solar system, to a puny streak that -- once it had dipped out of view from the northern hemisphere -- turned into a dazzling spectacle with multiple tails. As NASA points out, comets are "dirty snowballs" that coalesced when the solar system formed about 4.6 billion years ago, mostly "ice coated with dark organic material." The agency also describes them as
