    Blog 59: Pulsars
    I remember the discovery of pulsars; or maybe I don’t recall the actual announcement but discussions about them soon afterwards. With the passage of half a century, it’s hard to sort out. Word came in February 1968 that scientists had detected radio beacons in the cosmos, of the strangest type ever recorded, signals that repeated rapidly and at precise intervals. Nobody could resist wondering if the signals were the product of a spacefaring civilization. The findings came through the operation

In the chapter "Spring," he writes, with quotations chosen from two separated paragraphs, "Few phenomena gave me more delight than to observe the forms which thawing sand and clay assume in flowing down the sides of a deep cut on the railroad through which I passed on my way to the village. ...

M33 is also unusual for other reasons, including that a New General Catalog object resides within it. A quick explanation of the Messier (M) and New General Catalog (NGC) numbers: *** Charles Messier, 1730-1810, who served as chief astronomer at the Marine Observatory, Paris, searched diligently

    Blog 55: Visiting the Eagle Nebula with friends
    We had just called on a globular star cluster and Paul Ricketts wondered where our next adventure should take place. Knowing he likes nebulas, I suggested that we try to photograph one. He chose a complex, sprawling, breathtaking example in the summer sky, the Eagle Nebula. Ricketts ordered the University of Utah’s great 32-inch-diameter telescope to slew toward the nebula, technically named Messier 16 (M16), and the instrument began to shift position. This was Saturday night, June 30. A few
