The first lunar eclipse of 2021 is going to happen during the early hours of May 26. But this is going to be an especially super lunar event, as it will be a supermoon, a lunar eclipse and a red blood moon all at once. So what does this all mean?

  • In 2007, Japan's SELENE lunar orbiter, better known as Kaguya, became the first orbiter to capture high-definition images of the moon.
  • Kaguya's images helped scientists create a highly detailed topography of the lunar surface.
  • Artist Seán Doran synthesized and polished the Kaguya images to simulate what it's like to orbit the moon in real time.

  • A new, high-resolution image of the moon has been produced using radar astronomy.
  • Objects as small as five meters wide are clearly visible.
  • The image was part of a proof of concept test — a larger transmitter may soon be built.

  • Sensitive instruments reveal methane beneath the Arctic Ocean for the first time.
  • The gas is released in cycles that correspond to the tides.
  • Rising warming oceans may help to contain the greenhouse gas.

  • A new study says solar and lunar tide impacts led to the evolution of bony fish and tetrapods.
  • The scientists show that tides created tidal pools, stranding fish and forcing them to get out of the water.
  • The researchers ran computer simulations to get their results.
