Astronomy Picture of the Day - International Space Station Crosses the Sun

Explanation: Typically, the International Space Station is visible only at night. Slowly drifting across the night sky as it orbits the Earth, the International Space Station (ISS) can be seen as a bright spot about once a month from many locations. The ISS is then visible only just after sunset or just before sunrise because it shines by reflected sunlight -- once the ISS enters the Earth's shadow, it will drop out of sight. The only occasion when the ISS is visible during the day is when it passes right in front of the Sun. Then, it passes so quickly that only cameras taking short exposures can visually freeze the ISS's silhouette onto the background Sun. The featured picture did exactly that -- it is actually a series of images taken a month ago from Sant Feliu de Buixalleu, Spain with perfect timing. This image series was later combined with a separate image highlighting the texture of the active Sun which included several Sun's prominences around the edge.

Wow! Hats off to the photographer! Quite a feather in his cap to get that picture! And the Sun looks pretty darned good as well.

ISS is the most expensive ham radio repeater ever. I can usually make a contact or two if there is not too much competition. If anyone wants to learn more check www.ariss.org

That is so cool!

But, why didn’t they cross the Sun at night when it’s not so hot?

Asking for a Blonde...Oh, wait... ;)

The ISS boldly goes where no space station has gone before—right across the sun.

Picard:

“Let’s check this out. Mr. Sulu, warp 8. Engage.”

I don't know. Maybe they could land then too.
