The Cruel Sky of Everest

Today's Astronomy Picture of the Day could be a view of the cruel rocks of Everest or another Earth-bound mountain. Instead it is a view of Comet Churyumov-Gerasimenko as viewed by the ESA's Rosetta vehicle, here 67 kilometers away. Announced today: the landing site for the Philae probe.

Lost in the Noise

Today's Astronomy Picture of the Day is actually 100 astronomical pictures from the Hubble Space Telescope, resized and combined. An odd thing to do, one thinks.

110 Stories

110 Stories by the much-missed John M. Ford. Anything I could say today will not equal the impact of his thoughts about 09/11/01.

Another Thing I've Never Seen

Unfortunately, due to the light-soaked skies of New Jersey, today's Astronomy Picture of the Day is something I've never seen around here: the zodiacal light or "false dawn". "Mouseover" the image to get a guide. (Here's another thing I never see around here: the gegenschein!)

Towards the Core (003)

I guess it's a week of core samples on the Astronomy Picture of the Day! Today we have a beautiful "rich field" or wide angle view of the Sagittarius star cloud regions.

Sliding Spring

Today's Astronomy Picture of the Day shows Comet Siding Spring (C/2013 A1) passing through the rich star fields of the Small Magellanic Cloud, 47 Tucanae and NGC 362. Siding Spring is on it's way to a close encounter with Mars.

Towards the Core (002)

Today's Astronomy Picture of the Day is another view towards our galactic center. Messier 6, an open cluster in the constellation of Scorpius, is framed by dark and light nebula. Can you see the shape that gives Messier 6 it's popular name of "The Butterfly Cluster"?

At the End of the Very Small

Today's Astronomy Picture of the Day shows the recently-built Fermilab Holometer. The purpose? To explore the micro-universe of the Planck scale. Oh, Horatio.

Wizard!

Today's Astronomy Picture of the Day is of NGC 7380 and its embedded nebula, popularly known as the Wizard. Can you spot the wizard? (Hint: it helps if you "mouseover" the image, magic the stars disappear like magic!)

Towards the Core (001)

Today's Astronomy Picture of the Day gives us only one of many stunning views you can see as you look towards the center of our galaxy. Messier 20 and 21, a nebula (the Trifid) and an open cluster, both in the constellation of Sagittarius. Sweep the sky in that region (preferably dark, still and low humid skies!) with a pair of binoculars or a telescope with a wide view/low power eyepiece. You'll thank me later.
