    One of the Brightest Stars in the Sky is Evolving and Dying Before our Eyes

    August 17, 2022, Categories  Astronomy/Space

    Four panels of artistic drawing of Betelgeuse. First panel, a small burst on the surface of the star is seen. On the 2nd, the material has begun to leave the star, the 3rd shows the material dark as it cools, and the 4th is the star back to normal
    Artist’s impression of the aftermath of the SME, with the mass cooling and forming a cloud of dust which dimmed the star for a short period of time. The plot below outlines the real and expected brightness changes of Betelgeuse during this time. Credits: NASA, ESA, Elizabeth Wheatley (STScI)

    Nothing lasts forever, including the stars in our night sky. One of the brighter and more notable stars in our sky is Betelgeuse, the bright red supergiant in the shoulder of Orion.

    In late 2019, astronomers around the world grew giddy with excitement, because we saw this giant star get fainter than we’ve ever seen it before. Since Betelgeuse is at the end stages of its life, there was some speculation this might be a death rattle before the end.

    But the cause of the “great dimming” wasn’t ...

    Astrophysicists catch 2 Supernovae at the moment of Explosion

    March 22, 2016, Categories  Astronomy/Space

    The explosive death of this star, called KSN 2011d, reaches its maximum brightness in about 14 days. The shock breakout itself lasts only about 20 minutes, so catching the flash of energy is an investigative milestone for astronomers. The unceasing gaze of NASA's Kepler space telescope allowed astronomers to see, at last, this early moment as the star blows itself to bits.

    An international team of astrophysicists led by Prof Peter Garnavich, Notre Dame, has caught 2 supernovae in the act of exploding. Using the Kepler Space Telescope, the team spent 3 years observing 50 trillion stars for the chance to watch as supersonic shockwaves reached their surfaces after explosions deep in the core...
