    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

    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.

    Today the European Southern Observatory announced a stunning breakthrough. 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 71: Bennu
    The OSIRIS-REx spacecraft arrived at the asteroid called Bennu on Dec. 3, and already has made scientific discoveries: Bennu has few craters, boulders litter the surface like chocolate in a chocolate chip cookie, and the asteroid shows signs of the presence of water at some time in the past. NASA’s ludicrously-named spacecraft -- the acronym stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- cruised past the asteroid, having traveling 1.2 billion
