    Scientists chronicle the earliest stages of a supernova

    About a year ago, by chance, as the light it emitted reached Earth, a team of scientists in Israel observed it and for the first time collected data on the earliest stages from such an explosion, known as a supernova. The findings, published on Wednesday in the journal Nature, also indicate that the giant star, located in a neighboring galaxy called Messier 101, likely left behind a black hole after it exploded. The team, which included doctoral student and study lead author Erez Zimmerman, co

    A faster spinning Earth may cause timekeepers to subtract a second from world clocks

    For the first time in history, world timekeepers may have to consider subtracting a second from our clocks in a few years because the planet is rotating a tad faster than it used to. Clocks may have to skip a second — called a “negative leap second” — around 2029, a study in the journal Nature said Wednesday. “This is an unprecedented situation and a big deal,” said study lead author Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Di
