"The diffuse blue object near the center of the image is believed to be a cosmic "ghost" generated by a huge eruption from a supermassive black hole in a distant galaxy. This X-ray ghost, a.k.a. HDF 130, remains after powerful radio waves from particles traveling away from the black hole at almost the speed of light, have died off. As the electrons radiate away their energy they produce X-rays by interacting with the pervasive sea of photons remaining from the Big Bang - the cosmic background radiation."
So the ghost cannot hide from Chandra! We have our methods. Another one illustrated below where Active Galactic Nucleus - AGN are trying to hide but Chandra is not easily fooled! :-)

"This young galaxy contains an active galactic nucleus (AGN), or quasar, in its center, a luminous object powered by the rapid growth of a supermassive black hole. Some of the light from the AGN is obscured by dense gas and dust near the center of the galaxy. The galaxy itself is undergoing a growth spurt, as shown by bright regions of star formation in the spiral arms."
I love blue and I'm disgusted by pink. And all my life I have been cursed with the 'wrong' sex relative to my preference of colors. I can tell heartbreaking stories about how hard this has been. Maybe I would have been able to forgive the donor of a Hubble in pink though, even if there is no doubt that Hubble looks its best in blue.
The Atlantis shuttle just finished a good week of fixing the Hubble space telescope, a joint NASA/ESA project, to work for a few more years. Yet another great success for NASA, and the rest of the world, that will continue to learn more about outer space through the sharp eyes of Hubble.
Acknowledging that I might be among the few [girls] preferring the color blue I present to you two options for a baby shower gift that will stand out. A Hubble in blue and/or a Hubble in pink. NASA will not mind you framing one of these images, wrap it up and give the kid a bright future while slightly manipulate them to take an interest in space exploration. Even if the parents should ignore their responsibilities and 'forget' to encourage or even tell their kids about the option of studying the 'hard sciences', the kid itself will be reminded about the wonderful world that geeks live in when looking at their beautifully framed Hubble spacetelescope in blue or pink!
It is very exciting to watch the ongoing repair of the Hubble telescope. When NASA published this blueish image from this event I was 'sold', of course. The repair mission is delayed but that is OK as long as it is not canceled! :-)
It is a beautiful sunny spring day here in Norway. This extraordinary image of the Atlantis Shuttle passing by the Sun on it's way to fix Hubble is just underlining what a wonderful thing our Sun is - how much we enjoy this medium sized star. This is superb space art! Makes my day - totally - thanks to Takahashi&Canon for empowering Thierry Legault! :-)
Venus of Villendorf is my favorite figure. No way they are grotesque though. Who decided on those words describing these supercool historic objects? Todays silicon boobs on the other hand...grotesque! :-)
A good radar is worth it's weight in gold. I don't know, but it sure is very useful - and way cool to fly over those vast areas of Greenland and Iceland with nothing but ice. I know there are not much of a toilet onboard those planes so I hope they are careful with the eating and drinking....:-)
