There’s so much going on in this photo! The Gegenschein is the faint, blueish glow you can see rising from the horizon and going behind the eclipsed Moon.

Sharpest View of the Andromeda Galaxy, Ever.

The NASA/ESA Hubble Space Telescope has captured the sharpest and biggest image ever taken of the Andromeda galaxy — a whopping 69,536 x 22,230 pixels. The enormous image is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s pancake-shaped disc stretching across over 40,000 light-years.

What’s Up for February 2016?

Five morning planets, Comet Catalina passes Polaris and icy Uranus and icy Vesta meet near Valentine’s Day.

image

February mornings feature Mercury, Venus, Saturn, Mars and Jupiter. The last time this five-planet dawn lineup happened was in 2005. The planets are easy to distinguish when you use the moon as your guide. Details on viewing HERE.

If you miss all five planets this month, you’ll be able to see them again in August’s sunset sky.

image

Last month, Comet Catalina’s curved dust tail and straight ion tail were visible in binoculars and telescopes near two galaxies that are close to the handle of the Big Dipper. Early this month, the comet nears Polaris, the North Star. It should be visible all month long for northern hemisphere observers.

image

There will be more opportunities to photograph Comet Catalina paired with other objects this month. It passes the faint spiral galaxy IC 342 and a pretty planetary nebula named NGC 1501 between Feb. 10 – 29. For binocular viewers, the magnitude 6 comet pairs up with a pretty string of stars, known as Kemble’s Cascade, on Feb. 24.

image

Finally, through binoculars, you should be able to pick out Vesta and Uranus near one another this month. You can use the moon as a guide on Feb. 12, and the cornerstone and the corner stars of Pegasus all month long.

Mount Rainier shadow casts on the sky at sunrise. It only happens when the sun rises farther to the south and has to be in the exact position to where Rainier blocks the first rays of morning light. (Source)

I wish I could live somewhere with a view like this.

Falling Asleep Most Nights With The Stars Above And The Cool Air Coming In Through The Open Window. Sure

Falling asleep most nights with the stars above and the cool air coming in through the open window. Sure is a fun way to live.

This is probably the most majestic playlist I've ever heard.

LEAVING EARTH. “When Once You Have Tasted Flight, You Will Forever Walk The Earth With Your Eyes Turned
LEAVING EARTH. “When Once You Have Tasted Flight, You Will Forever Walk The Earth With Your Eyes Turned

LEAVING EARTH. “When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.” For courageous travellers. Go forth and explore. [listen]
