Stay up tonight online to watch an awesome lunar eclipse with our astronomer pals at NASA:
Spring is here and ready to capture the world's attention with a total lunar eclipse. The eclipse will begin early on the morning of April 15 at approximately 2 a.m. EDT. If you have questions about the eclipse, this will be your chance! NASA astronomer Mitzi Adams and astrophysicist Alphonse Sterling will also answer questions in a live web chat, beginning on April 15 at 1 a.m. EDT and continuing through the end of the eclipse (approximately 5 a.m. EDT). The chat module will go live on this page at approximately 12:45 a.m. EDT. Convert to your local time here. A live Ustream view of the lunar eclipse will be streamed on this page on the night of the event, courtesy of Marshall Space Flight Center. The feed will feature a variety of lunar eclipse views from telescopes around the United States.Read the rest
Boing Boing reader Cory Poole is a 33-year-old math and science teacher at University Preparatory School in Redding, CA. He sends in this beautiful video of yesterday's annular solar eclipse, and says:
This is a 60 second time-lapse video made from 700 individual frames through a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. The pictures were shot in Redding, CA, which was directly in the annular eclipse path. The filter on the telescope allows you to see the chromosphere which is a layer that contains solar prominences. The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.
On May 20-21 (this coming Sunday night through this coming Monday morning), sky-watchers in Asia and much of the U.S. will be able to view a “ring of fire” eclipse or a partial eclipse of the Sun, depending on their location. The rest of the world, including our readers along the East Coast of the US, will have to settle for viewing this special celestial event online.
The shadowandsubstance.com astronomy website has a totally awesome animated map showing how the eclipse will look to viewers in each U.S. state. But more importantly, he gives the best eclipse advice you'll get anywhere:
The safest way to view this event is to attend a planetarium, observatory or local astronomy club on May 20th.
Here's an index of astronomy clubs around the world.
For DIYers, a pinhole projector is another option.
