I going to try and do an Astronomy Monday kind of thing, with either photos or little NASA vids because somethng interesting seems to be always going on.
          While this is older, from 2012, this photo of our neighbor, Venue crossing our parent star, never gets old. So stunning!

Explanation: An unusual type of solar eclipse occurred in 2012. Usually it is the Earth's Moon that eclipses the Sun. That year, most unusually, the planet Venus took a turn. Like a solar eclipse by the Moon, the phase of Venus became a continually thinner crescent as Venus became increasingly better aligned with the Sun. Eventually the alignment became perfect and the phase of Venus dropped to zero. The dark spot of Venus crossed our parent star. The situation could technically be labeled a Venusian annular eclipse with an extraordinarily large ring of fire. Pictured here during the occultation, the Sun was imaged in three colors of ultraviolet light by the Earth-orbiting Solar Dynamics Observatory, with the dark region toward the right corresponding to a coronal hole. Hours later, as Venus continued in its orbit, a slight crescent phase appeared again. The next Venusian transit across the Sun will occur in 2117.

The problem with LJ/DW: we all think we are so close, but really, we know nothing about each other. So I want you to ask me something you think you should know about me. Something that should be obvious, but you have no idea about. Ask away. Then post this in your journal and find out what people don't know about you
