How white holes (might) be created
Astronomers said on Wednesday they had snared light from a bright, ancient galaxy with a super-massive black hole at its core, a finding that would help explain aspects of the young Universe. The phenomenon is called a quasar, which are very bright but very distant galaxies with a mighty black hole at their heart. Until now, the most distant quasar ever seen sent light 870 million years after the Big Bang, which is believed to have occurred nearly 13.7 billion years ago. This record has now been beaten by European astronomers, who after a five-year probe found a quasar whose light was emitted just 770 million years after the cosmic birth. ULAS J1120+0641 has a "redshift" -- a signature of red light that is a telltale of distance -- of 8.6, meaning that the light took 12.9 billion years to reach us.

Space Solar Power (SSP) is clean and green energy at a low cost with minimal environmental impact. PowerSat Corporation is a pioneer in generating safe, clean, reliable energy from space. Solar energy is captured via satellites (known as powersats) and transmitted wirelessly to receiving stations at various points around the globe. Thousands of megawatts can be harnessed and shifted between receiving stations thousands of miles from each other - all in a matter of seconds. (More about PowerSat) What is Space Solar Power?

Most Distant Quasar Found A team of European astronomers has used ESO's Very Large Telescope and a host of other telescopes to discover and study the most distant quasar found to date. This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early Universe. The results will appear in the 30 June 2011 issue of the journal Nature. "This quasar is a vital probe of the early Universe. It is a very rare object that will help us to understand how supermassive black holes grew a few hundred million years after the Big Bang," says Stephen Warren, the study's team leader. Quasars are very bright, distant galaxies that are believed to be powered by supermassive black holes at their centres.

Stuart Gary for ABC Science Online Updated Fri 6 May 2011, 5:48pm AEST An intriguing new hypothesis suggests some black holes could have formed before the formation of our universe. The work by Professor Bernard Carr from Queen Mary University in London and Professor Alan Coley from Canada's Dalhousie University, examines a cosmology in which the universe goes through cycles of birth and death. Some black holes may be older than time
1153 - Christmas Comet Lovejoy Captured at Paranal eso1153 — Photo Release 24 December 2011 The recently discovered Comet Lovejoy has been captured in stunning photos and time-lapse video taken from ESO’s Paranal Observatory in Chile. The comet graced the southern sky after it had unexpectedly survived a close encounter with the Sun.
In response to an earlier post I did about Solar Flares and GPS disruption, someone commented about the affects that solar activity can have on human behavior. Having read more about it since then, it seems that there are some interesting correlations. Here are some links I found on the subject: Sunspots and Human BehaviorThis article was published in the year 2000, just after the last Solar Maximum: Solar Activity and Human Behavior: a link?

“Not explaining science seems to me perverse. When you’re in love, you want to tell the world.” -Carl Sagan Nothing lasts forever in this Universe, not even the seemingly timeless stars in the sky. At any moment, any one of the brilliant, twinkling points of light from across the galaxy could run out of fuel, ending its life as we know it.

Bad Astronomy Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news.
Your Age on Other Worlds | Exploratorium Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. This brings up the question of how we define the time intervals we measure. What is a day? What is a year? The earth is in motion. Actually, several different motions all at once.
Mysteries in slow motion: Videos offer a glimpse into an aerial world we never see By Daily Mail Reporter Updated: 00:27 GMT, 15 January 2012 A series of high-speed animal flight videos are producing an amazing glimpse aerial world most of us have never seen before. Amateurs videographers, with a bit of luck, can use inexpensive digital cameras to turn blurred images into clear illustrations of animal and insect behaviour. A Dutch programme named Vilegkunstenaars asked videographers and animal lovers around the world to capture nature in flight, digg.com reports. They sent high speed video tools to amateurs and the results that came back were stunning.
