    Blog 75: Gravity's shadow
    April 10, 2019, should be recorded in the annals of science as one of the most significant dates. It's when the first photo of a black hole was released. 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

Its four huge telescopes took spectra of the atmosphere of an exoplanet 129 light-years away, discovering a violent worldwide storm of blazing-hot carbon monoxide, iron vapor and dust. About 30 times as distant as the nearest star to our solar system, the planet is dubbed HR8799e, one of at least four exoplanets orbiting the star HR8799 in the constellation Pegasus. The relatively young star is about 1 1/2 the mass of

    Blog 72: Depth
    Sometime in the early-to-mid 1960s, when I was a teenager on the American missile base at Kwajalein, Marshall Islands, I snorkeled beyond the drop-off on the lagoon side; this is the descending slope where the water gets deeper the farther you swim from the reef. The sandy bottom tilts gradually until suddenly it plunges. Beyond that, the lagoon is too deep to see the bottom. Shimmering dim green shafts of sunlight sliced down all around me, reaching farther and farther into the depths, until
