“The Sun can be viewed directly only when using filters specifically designed for this purpose. Such filters usually have a thin layer of aluminum, chromium or silver deposited on their surfaces that attenuates ultraviolet, visible, and infrared energy“.
Above excerpt has been taken from NASA Website – http://eclipse.gsfc.nasa.gov/SEhelp/safety.html, where NASA’s page suggests usage of SOLAR FILTERS [...]
Solar Filters are supposed to be the Most safe method for viewing Solar Eclipse. Hence that is the reason, all over world, people use Convenient and Easily available Solar Filters for viewing Solar Eclipses. But one has to take proper care and caution while using and selecting the right solar filters :
If you are using [...]
Solar Eclipse is a fascinating and a Celestial Event filled with Mysteries for many, and a “hay time” for many Astrologers, and publicity crazy societies and individuals etc., because, it is the time they want to make themselves popular by propogating unscientific fears, panic and for them even the popular saying goes wrong : MAKE [...]
Shortly after the Moon formed, an asteroid smacked into its southern hemisphere and gouged out a truly enormous crater, the South Pole-Aitken basin, almost 1,500 miles across and more than five miles deep.

Using data from a NASA radar that flew aboard India’s Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon’s north pole. NASA’s Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice More here: NASA radar finds ice deposits at Moon’s north pole; additional evidence of water activity on Moon AKPC_IDS += "805,";Popularity: 1% [?] Read More →
Like a hard-driving athlete whose joints need help, the giant “Mars antenna” at NASA’s Deep Space Network site in Goldstone, Calif. has begun major, delicate surgery. The operation on the historic 70-meter-wide (230-foot) antenna, which has received data and sent commands to deep space missions for over 40 years, will replace a portion of the hydrostatic bearing assembly.

Planetary scientists have been puzzling for years over the honeycomb patterns and flat valleys with squiggly edges evident in radar images of Saturn’s moon Titan. Now, working with a “volunteer researcher” who has put his own spin on data from NASA’s Cassini spacecraft, they have found some recognizable analogies to a type of spectacular terrain on Earth known as karst topography.

One year ago this week, NASA’s Kepler mission soared into the dark night sky, leaving a bright glow in its wake as it began to search for other worlds like Earth. View post: NASA’s Kepler Mission Celebrates One Year in Space AKPC_IDS += "811,";Popularity: 1% [?] Read More →
NASA’s newest Mars orbiter, completing its fourth year at the Red Planet next week, has just passed a data-volume milestone unimaginable a generation ago and still difficult to fathom: 100 terabits.

Mars Express encountered Phobos March 3, smoothly skimming past at just 67 km, the closest any artificial object has ever approached Mars’ enigmatic moon. The data collected could help unlock the origin of not just Phobos but other “second generation” moons.

Keeping an infrared telescope at very cold operating temperatures isn’t an option, it’s an absolute necessity. Serving as a radiation blocker, the Webb telescope sunshield is subjected to nearly 100,000 thermal watts of solar heat, and reduces that to one tenth of a watt on the cold side, a million to one reduction.

New studies of ripples and dunes shaped by the winds on Mars testify to variability on that planet, identifying at least one place where ripples are actively migrating and another where the ripples have been stationary for 100,000 years or more.

Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars.
