    Blog 38: Another supernova!
    Patrick Wiggins has done it again! At 2:49 a.m., Jan. 14, the Tooele County, Utah, amateur astronomer photographed a field of stars and galaxies in the area of Ursa Minor (the Little Dipper) -- and caught his fifth supernova. This one, which he discovered four years to the day after his first astonishing find, is hosted by the barred spiral galaxy NGC 6217. It's in the galaxy's sparsely-populated outskirts. A physicist notes that galaxies can have disks that extend beyond their obvious

    NASA’s long-term goals changed on Dec. 11, 2017, shifting from human exploration of asteroids to a return to the Moon. The 2010 version of the National Space Policy contained these instructions: "Set far-reaching exploration milestones. By 2025, begin crewed missions beyond the moon, including sending humans to an asteroid. By the mid-2030s, send humans to orbit Mars and return them safely to Earth …." In his Space Policy Directive 1, President Donald Trump removed that section and replaced it

    Blog 35: Cosmic discoveries
    University of Utah astrophysicists and their partners in the Telescope Array Project are working to solve the mystery of the origins of cosmic rays. And they may be onto an astounding discovery, that many of the highest-energy particles come from a region near the Big Dipper. The background "Cosmic rays" is a misnomer, as they aren't beams but physical bits of material from elsewhere in our Milky Way galaxy and far more distant sources. These subatomic particles zap into the atmosphere

    Blog 34: Planetary nebulas ... and Baby!
    Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. -- First stanza of Dylan Thomas' "Do Not Go Gentle into that Good Night," 1951. A star is a perfect example of how to go into that good night. If larger than about eight times the Sun's mass, it will explode as a supernova, for a few days or weeks shining brighter than the entire galaxy that hosts it. If in the class of the nuclear furnace at the center of our solar
