  1. MESMERIZING The Sun's roiling surface in higher resolution than ever before. "Cells" are roughly the size of Texas. Just-released video from the 's Daniel K. Inouye Solar Telescope, Maui.

  2. Super Bowl Sunday was a bad day to be a Chicken in America. Actually, so is any other day. Americans eat **one-million** chickens per hour.

  3. While you’re watching… If the Football field were a timeline of the 14-billion year old Universe, with the Big Bang at one end, then at the other end, the width of a single blade of grass spans 30,000 years of human history, from Cro-Magnon to the present.

  9. Climate versus Weather… [Video: 2 min]

  10. Overnight January 4 / 5 - Earth at Perihelion - The closest distance to the Sun in our annual elliptical (oval-shaped) orbit. If you see astrophysicists dancing in the streets, this could be why.

  11. Not to reveal my age, but back in my day, we drew Betelgeuse bright (at Orion’s left armpit) relative to other stars in Orion.

  12. Beginning late summer of 2019, the reddish star Betelgeuse has dropped from the 7th to the 21st brightest star in the nighttime sky. No need to panic, but If it exploded, the flash would be visible in the daytime, and rival the brightness of the Moon for weeks.

  13. Betelgeuse was born about 10 million years ago — long after Earth's big dinosaurs roamed the land. But the star is now near death. No need to panic, but stellar evolution models tell us that it will likely explode as a Supernova sometime within the next 100,000 years.

  14. Odgovor korisniku/ci

    Orion was drawn facing away from us for most illustrations of the classical period.

  15. The star Betelgeuse is so large, if you swapped it with the Sun, it would engulf the orbit of Mars and extend all the way through the asteroid belt. No need to panic, but at 700 light years, it's the closest star to the Sun that will end its life in a Supernova explosion.

  16. No need to panic, but the red supergiant star Betelgeuse (yes there is a star with that name), one of the brightest in the nighttime sky, marking the left armpit of the constellation Orion, is mysteriously dimming, having lost 60% of its brightness across the past six months.

  17. Odgovor korisnicima

    Animals — especially dogs — have always liked my books.

  18. Santa knows Physics: Red light penetrates fog way better than blue light. That’s why Bennie the blue-nosed Reindeer didn’t get the gig.
