Details of our Milky Way
Enjoy the breath taking portrait of our Milky Way in detail.
The image spans the region of sky from the constellation of Sagittarius to Scorpius. The very bright and colourful feature towards the right of the image are the Rho Ophiuchi and Antares regions. Darker areas such as the Pipe and Snake nebulae also stand out.
The dusty lane of our Milky Way runs obliquely through the image, punctuated with bright, reddish nebulae including the Lagoon and the Trifid nebulae. A supermassive black hole is at the centre of our galaxy.

Homeschooling and High School
Parents thinking about homeschooling in the early years and then sending them off to the local high school for their last four years may want to rethink that strategy.Drew Gamblin, a 16 year old gifted student, desires to go to the local public high school after being homeschooled. He hopes to experience "the memories" and graduate with his peers. Gamblin is being held back, however, because

Student Education-NASA poised to stop work on shuttle extension option
Facing a tight budget, a 2010 deadline to end space shuttle operations and a lack of concrete political support to fund additional flights or stretch out the current manifest, NASA managers are meeting this week to discuss the impact of ending efforts that have been keeping open the option of extending the shuttle program past the current deadline.
Complicating the picture for NASA planners, there is a very real possibility that one or two of the final shuttle missions currently envisioned will slip into the October-December 2010 timeframe, i.e., the first quarter of fiscal 2011. There is no money in NASA's projected 2011 budget for any shuttle operations beyond $300 million or so intended for retirement activities.
As a result, NASA now plans to terminate work that kept open the option of a shuttle extension when the current legislation expires at the end of the month.

Advice for Aspiring Homeschooler
Crunchy Con author and BeliefNet blogger, Rod Dreher, had a reader write to him seeking advice regarding homeschooling. A reader writes to say that his five year old came home from public school kindergarten with a flyer alerting parents that the kids are about to have a whole week of "Just Say No to Drugs" education. It shocked him that kids as young as this are being subjected to this sort of

Student Education-Evidence found of lake on Mars
A long, deep canyon and the remains of beaches are perhaps the clearest evidence yet of a standing lake on the surface of Mars, say scientists.
Images from a camera called the High Resolution Imaging indicate water carved a 50 kilometre long canyon.
The presence of water on Mars is widely accepted. The Mars Phoenix mission last year found frozen water on the surface of Mars, and there is also evidence that water may still seep to the surface from underground.
Planetary scientists have also seen what could be the shores of giant rivers and seas, but some of the formations could also arguably have been made by dry landslides.
The researcher says that this is the first unambiguous evidence of shorelines on the surface of Mars.

Student Education-Water molecules on Lunar surface
NASA scientists have discovered water molecules in the polar regions of the moon. Water molecules are greater than predicted , but still relatively small.
Hydroxyl, a molecule consisting of one oxygen atom and one hydrogen atom, also was found in the lunar soil.
NASA's Moon Mineralogy Mapper, or M3, instrument reported the observations. M3 was carried into space on Oct. 22, 2008, aboard the Indian Space Research Organization's Chandrayaan-1 spacecraft. Data from the Visual and Infrared Mapping Spectrometer, or VIMS, on NASA's Cassini spacecraft and the High-Resolution Infrared Imaging Spectrometer on
NASA's EPOXI spacecraft contributed to confirmation of the finding. The spacecraft imaging spectrometers made it possible to map lunar water more effectively than ever before.
The M3 team found water molecules and hydroxyl at diverse areas of the sunlit region of the moon's surface, but the water signature appeared stronger at the moon's higher latitudes.

Student Education-Amazing Enceladus Images
Image of plume from far away.
In my previous post Happy Halloween from Cassini Spacecraft Team i mentioned about Cassini spacecraft going to the Moon of Saturn, Enceladus on 2th November, 2009.
Cassini has captured some amazing images of the plumes shooting from Enceladus , they are simply the raw images.
The objective of Cassini is to analyse the particles in the plume with the instruments that can detect the mass , size, charge, speed and composition.
These are the first images of the plume and are amazing.

Student Education-Hardball on Homeschooling
Last night, MSNBC's Chris Mathew's announced his litmus test for Republican candidates and wrongly stereotyped homeschoolers in the process. In a post election round-up he posed this question to Club for Growth President, Chris Chocola, after Chocola talked about the limited role of government: MATTHEWS: Last question—here‘s my litmus test—are you pushing home schooling? CHOCOLA: We don‘

Student Education-A Christmas gift from Hubble Telescope
Hubble Space Telescope has produced a lot of images and hence the The Big Picture at The Boston Globe is doing an advent calender to countdown the days until Christmas.
Until Christmas every day you can see a new image by Hubble Space Telescope . The images are awesome.

Student Education-The real epidemic in our schools
Obama declared H1N1 a national emergency but there's another virus that is threatening our children's minds that could prove more widespread than once believed. Big Hollywood has posted 11 more videos of children in various schools around the country singing praises to Obama and quoting his speeches. This is about brainwashing our children into Leftist identity politics. Sure, the schools

Soyuz Rocket ready for liftoff
Russian Soyuz rocket has arrived to the launch pad on Monday, Sept. 28, 2009, at the Baikonur Cosmodrome in Kazakhstan. The Soyuz is scheduled to launch the crew of Expedition 21 and a spaceflight participant on Sept. 30, 2009.

Graveyards of solar systems around dead suns
Using NASA's Spitzer Space Telescope to study white dwarf stars, astronomers have found the dusty remains of ancient solar systems.
White dwarfs are the dense glowing embers of Sunlike stars. While their atmospheres should consist entirely of hydrogen and helium, they are sometimes contaminated with heavier elements like calcium and magnesium.These metals really shouldn't be there.That means they are external pollutants.
The rocky debris imaged by Spitzer probably represents the innermost planets of a solar system that were ripped apart by the gravitational forces of their host star at the end of its life. Extrapolating our own Sun's life into the white dwarf phase, simulations show that the Earth may not survive, but that Mars and asteroid belt would probably lie outside of the Sun's grasp.
Perhaps the most exciting and important aspect of this research is that the composition of these crushed asteroids can be measured using the heavy elements seen in the white dwarf. In one case 17 heavy elements were found in one star, yielding a composition that closely matches the equivalent of a combined Earth and Moon. The next step will be to search for those ingredients that may suggest that life-bearing planets may once have existed in these systems.
