On Monday, November 11, 2019, one of my favorite celestial events occurs – a transit! Think of a transit as an “eclipse lite” – a planet will pass between Earth and the Sun, and we’ll be able to observe the planet’s shadow moving across the Sun. Here are six questions to ponder during this month’s transit of Mercury.
I think it surprises a lot of people that a mission as successful as the Cassini-Huygens Mission would be terminated on purpose. Not just shutting the spacecraft off, but terminated with such style by sending it on a destructive dive into Saturn’s atmosphere. Cassini will burn up and be destroyed in a similar way that a meteorite is broken up in Earth’s atmosphere.
In late March, I traveled to Puerto Rico to conduct observations of Venus using the Arecibo Observatory telescope. It was the second time I traveled to the observatory to make radar measurements of the surface of Venus. Even though it was my second time there, the size and capability of the telescope still impressed me; the telescope is largest single-aperture telescope ever constructed.
