Astronomy Picture of the Day

For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before. It's true that supernovae and novae expel matter out into space. But while the V838 Mon flash appears to expel material into space, what is seen here is actually an outwardly moving light echo of the bright ... Full Story

EarthSky Tonight—Nov 1,  Looking out our Milky Way galaxy’s south window

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org On this evening with no moon, use the planet Jupiter and Great Square of Pegasus to star-hop to our galaxy’s south window.

 Can you show me a detailed view of the Milky Way center? Here is how to do it. Every year in early November, the Great Square of ... Full Story

Earthsky Tonight — April1, 2010 Follow the arc to Arcturus

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Now is the perfect time to look outside in the evening and learn a phrase useful to skywatchers. Scouts learn it. Grandparents teach it to kids. It was one of the first sky tools I learned to use in astronomy. The phrase is: follow the arc to Arcturus. First locate the Big Dipper asterism in the northeastern sky in mid-evening, maybe around 9 p.m. Can’t find the Big Dipper? Look ahead to our chart ... Full Story

Earthsky Tonight – Dec 25 2009 Northern Cross

Earthsky Tonight – Dec 25 2009 Northern Cross stands upright on winter evenings

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org We get many questions from people in northern latitudes about if and when they can view the Southern Cross in their portion of the sky. The truth is that unless you live close to the tropics (Hawaii, or the southernmost parts of Texas or Florida for those of us in the U.S.), you will not be able to view the Southern Cross, also known as the constellation Crux. To find out how to locate Crux in Hawaii right now, look ... Full Story
