I like it because it is bluish, of course, and because it is different from most other moon images. :-)

If your Santa Claus is the one who lives at the North Pole, I certainly hope you tell your kids that the Santa then has two (geographical and magnetic) homes and that they move around on a regular basis. Above is an image of the North Magnetic Pole, at the moment residing on Canadian territory.

As I was looking around the internet for Christmas Tree Cluster images I came over a couple of globules. I like the pictures, even if they are pinkish. Hubble Heritage team has put together a couple of nice presentation of the phenomena. I like the zooming video - that puts it into perspective at least a where in space perspective.

Christmas Tree Series - V




Christmas Tree Cluster V

Credit: R Jay Gabany


The Christmas Tree Star Cluster is one of four astronomical objects identified within NGC 2264. The other three being the Cone Nebula Nebula, the Fox Fur Nebula and the Snowflake Cluster. You'll find them all in the Monoceros constellation, one of Orions neighbours.

The Christmas Tree Cluster (NGC 2264) was discovered by William Herschel in 1784 and can be observed with binoculars if you so wish. The star cluster includes many interesting and curious structures in the gas and dust. At the top of the frame, the dark triangular feature is known as the Cone Nebula ( mentioned above). The region close to the brightest star has a strange, fur-like texture that has led to the name Fox Fur Nebula, also mentioned above.

Energetic hot young stars emitt intense ultra-violet light causing the overall red colors of the image. The stars themselves appear blue as they are hotter, younger and more massive than our own Sun. Some of this blue light is scattered by dust.

I've collected a few images of the Christmas Tree for you to enjoy these holidays. Links to the original and more scientific information about this spectacular view in the sky is integrated in the text.

The image above is published November 2008 on Cosmotography and appears on APOD 25th December 2008 (click image for more details). Note that I have rotated all the Christmas Tree Cluster images so that we see 'a tree' standing upright.

Hippopotamus for Christmas




Hippo for Christmas



Xineann told me that she really wanted a Hippo for Christmas. In case she hasn't got one yet, here is an ancient one. She has to look for the stars, but that she is used to as she is a keen reader of Celestial Art of whatever day over at a certain nice man's blog.

This ancient Egyptian celestial Hippo came with a croco on her back. It is all the same a Hippo. :-)

As we are focusing in on the Cone Nebula in the Christmas Tree Cluster you might as well get a really close look. It is rather peculiar and pretty, the Cone Nebula. It can certainly survive a close-up with dignity.:-)

Culture is well represented in the heavens as names on constellations, nebulae, stars etc. That is also the case for the Christmas tree. In the heavens the Christmas tree contains a few other elements such as a Cone, just like one would expect. I can't say I've seen a Fox Fur on a Christmas tree here on Earth, though, but it sure has got one in the sky version of a Christmas tree.

Darkness




In The Dark

Abell 85


We live in a dark envelope these last days of December. It is a returning subject of discussion among us "Northlings". Winter Solstice is just around the corner, 21st December the Sun 'will turn', as we say, most of us knowing the Sun actually does no such thing. Anyways, the important point is that we'll see more of the Sun from that day on.

The timing is thus perfect for discussing dark matters while we live through the darkest of times (of the year). With our minds focusing on the light to come we should remember that it is in fact a lot darker than we can imagine - even darker than on the North pole at Winter Solstice. SU's very own bigdirtymosh understands this and uses his space on the Discovery Channel to shed some light on the deep, deep, immense darkness out there.








Illustration: NASA/CXC/M.Weiss

Dark energy is estimated to contribute about 74% of the energy in the Universe, dark matter about 22% and normal matter about 4%. Only the normal matter can be directly detected with telescopes, which includes the hot gas emitted by galaxy clusters.

Solar Flare Surprise Edition


It is not like our satellites, including especially the GPS satellites, are keen on too much solar activity. Ferocious blasts are fun but dangerous as they knock out navigation instruments and what not. But, we haven't hardly had ANY SUN SPOTS IN AGES FOR CHRIST SAKE!! So I guess we can afford a little happiness over this blast of a surprising solar flare. And let instruments be malfunctioning instruments for a short little while. :-)

Hebes Chasma is an enclosed trough, almost 8000 m deep, in Valles Marineris, the Grand Canyon of Mars, showing Light Toned Deposits. This is an area where water is believed to have flowed.



Water on Mars is old news. Learning about the details of this water will never grow out of fashion though. As on this planet, knowing the amount and behavior of ground water is a hot topic.

Full Moon over Tomb




Moon over Humayun's Tomb


Photo: Atish
The Full Moon shines above the World Heritage Site of Humayun's tomb complex in Delhi, India.


The Humayun's Tomb, Delhi, built from 1570-1578, was the first garden-tomb on the Indian subcontinent. It inspired several major architectural innovations, culminating in the construction of the Taj Mahal.

Humayun (1508 – 1556) was the second Mughal Emperor who ruled modern Afghanistan, Pakistan, and parts of northern India from 1530–1540 and again from 1555–1556. After Humayun died in 1556, his widow Hamida Banu Begam, also known as Haji Begam, commenced the construction of his tomb in 1570, fourteen years after his death. It is the first distinct example of proper Mughal style, which was inspired by Persian architecture.

Climate Change Refugees




Climate Refugees 2010



Cartographer: Emmanuelle UNEP/GRID-Arendal


Fifty million climate refugees by 2010.



"Today we find a world of asymmetric development, unsustainable natural resource use, and continued rural and urban poverty. There is general agreement about the current global environmental and development crisis. It is also known that the consequences of these global changes have the most devastating impacts on the poorest, who historically have had limited entitlements and opportunities for growth."

And yet we continue to discuss who or what causes the changes. This is perhaps the only topic that I will agree with Mrs Sarah Palin; we need to act on and adjust to climate change now. Some will argue that if we don't know what causes climate change we cannot make the right decisions. As a scientists I am of course not going to argue against understanding and knowledge production. However, we have technology and information to monitor mother Earths behavior today AND we can model pretty well the near future as well. Enough to act.
