  • Saturn (and a conjunction with Jupiter)

    Young Astronomers Blog, Volume 28, Number 24. Every so often, two (or more) planets appear close to each other in the night sky. We call this a conjunction.

  • Water, Phosphine, and the possibility of life elsewhere in the Solar System

    Young Astronomers Blog, Volume 28, Number 20. Although many have dreamed about life on other worlds, so far, life has only been found on the Earth. The search for life has gone down one avenue as new “exoplanets” are found and we get closer to finding a planet like the Earth orbiting another star. This…

  • Rocks and Minerals

    Young Astronomers Blog, Volume 28, Number 19. Walk outside and look down. You might see a few rocks. A casual glance might reveal that the rocks around you are gray, or they might have a hint of color. A few might even sparkle in the sun. Although they look simple, rocks are hard! A more…

  • Jupiter

    Young Astronomers Blog, Volume 28, Number 18. If you look up in the night sky over the next few months you might see what looks like a bright star. However, it is not a star, it is the planet Jupiter. Jupiter is the largest planet in our solar system, at 11 times the width of…
