    Blog 78: Anatomy of a monster
    Judging by Hollywood's always-ludicrous treatment of black holes, scientific knowledge about them is sadly scarce. Probably most know that a black hole is a system in space where so much mass is packed into such a small region that its tremendous gravity can shred and pull in a star that wanders too close; also, that nothing can escape once inside. That may be most of the information many have about block holes. But with the April 10 release of the first photograph of one, now is a good time to

    What sort of solar system object hasn't undergone close inspection by spacecraft or humans? The sun? Monitored continuously. Planets? All visited by by probes, including Pluto, which I sentimentally insist remains a planet. Rocky moons? Never forget July 20, 1969. Icy moons? Numerous loops around Jovian and Saturnian examples. Asteroids? OSIRIS-REx orbits asteroid Bennu with instructions to bring back a sample in 2023, while earlier this month the Japanese probe Hayabusa 2 dropped an explosive

Phenomena of such extreme conditions that their existence was questioned a few decades ago, black holes are among the strangest products of nature. They are gravity wells that nothing can escape, that may have no material substance but exert crushing gravity; they are cosmic beasts so powerful that they distort space and time. Anything

    Blog 74: Science and spirituality
    We humans can experience profoundly spiritual feelings when thinking about celestial objects -- and we always have, from the times of the earliest belief systems that we know much about, right up to this minute. But does spirituality have a legitimate place in astronomy? ** The Sun The official worship of the Sun as a giver of life originated in the deep past. The pharaoh Akhenaton (father of Tutankhamun), who ruled Egypt from 1353 BC to 1336 BC, imposed a new cult of the Aton, the solar disk,
