The earth is a planet a rock that spins about the sun. If it was not for the athmosphere the place would be quite cold. The athmosphere is a mixture of gases, Nitrogen, Oxygen, Noble gases, Carbon Dioxide and others including Methane.

All the Earthquake news
The USGS (United States Geological Survey) reported a 8.9 magnitude earthquake on Friday, March 11, 2011 at 05:46:23 UTC near the east coast of Honshu, Japan, which was detected 13 minutes later at Met Éireann's Valentia Observatory.
A fantastic calender for space spotting (amateur astronomy) .... http://www.seasky.org/astronomy/astronomy-calendar-current.html
this guys photos are worth checking out http://www.nightskyhunter.com/Sky%20Events%20Now.html
On the first and third Wednesday of every month it’s possible to visit one of Ireland’s oldest scientific institutions and look at the stars the way they were meant to be seen – through a huge telescope beside a dump.
new shower in December
13/14 ... must check it out
Comet of origin: 109P/Swift-Tuttle
Radiant: constellation Perseus
Active: Perseids begin to rise early August.
Peak Activity: Night of Aug. 12-13
Peak Activity Meteor Count: Approximately 50 meteors per hour
Time of optimal viewing: Crescent moon will set early in the evening, allowing for dark skies all the way up until peak viewing just before dawn
Meteor Velocity: 61 kilometers (38 miles) per second
Note: The Perseid meteor shower is one of the most consistent performers and considered by many as this year's best shower. The meteors they produce are among the brightest of all meteor showers.
The next total solar eclipse is in November 2013 over the South Pacific
02 December 2010 - 2010 in the top three warmest years, 2001-2010 warmest 10-year period
The year 2010 is almost certain to rank in the top 3 warmest years since the beginning of instrumental climate records in 1850, according to data sources compiled by the World Meteorological Organization (WMO). The global combined sea surface and land surface air temperature for 2010 (January–October) is currently estimated at 0.55°C ± 0.11°C (0.99°F ± 0.20°F) above the 1961–1990 annual average of 14.00°C/57.2°F.
The Green House Effect
Saving the Planet
What you can do to help reduce CO2 emissions and save you mon€y.-
- Turn off the heater
- at night before you go to bed (save 600 kg CO2 per quarter)
- Use a microwave for most of your cooking needs (save 810 kg CO2 per quarter)
- Use a clothes line rather than a dryer (save 260 kg CO2 per quarter)
- Drive smoothly with the flow of traffic (save 140 kg CO2 per quarter)
- You can ask your electricity supplier to source the energy you use from renewable sources such as wind, solar and hydro-power
- Choosing a clean energy alternative makes it easy for everyone to reduce their greenhouse gas emissions at home and work.
- Use low energy bulbs.
- Insulate your home to save energy.
- Turn off all unnessary electrical appliances.
- Get solar panals installed on your roof for heating and electricity.
- Use 'A' rated appliances.
- Improve your windows so heat doesn't get out and cold doesn't get in.
- Use your normal shower instead of you electric shower, if possiably.
- Don't leave things on stand-by or sleep-mode, turn them off.
- Turn off everything at night.
- Turn things off at the plug when not in use.

10 science.ie facts about snow
Published 2 December 2010
1. Snowflakes start as ice crystals that are the size of a speck of dust. As the crystals fall they join up with other crystals to form a snowflake, which will usually have six sides. Scientists grow snow crystals in labs to study snowflake structure.
2. Why is snow white? Most natural materials absorb some sunlight which gives them their colour. But snow reflects most of the sunlight. What little sunlight is absorbed by the snow is absorbed uniformly over the wavelengths of visible light, giving snow its white appearance.
3. Snow acts like a mirror. Snow and ice at the North and South Poles reflect the heat of the Sun back into space.
4. When does it snow? Snow can fall when temperatures at ground level are above freezing, because it forms high up in the atmosphere.
5. Is it ever too cold to snow? It can snow even at incredibly cold temperatures as long as there is some source of moisture and some way to lift or cool the air. But most heavy snowfalls occur when air temperatures near the ground are around -9 degrees Celsius or warmer, as air can hold more water vapor at warmer temperatures.
6. Snow terminology: experienced skiers have their own terms to describe different types of snow. These include “fluffy snow”, “powder snow”, and “sticky snow”, “champagne powder” and “mashed potatoes”.
7. Frost is different to snow. Frost forms when water vapor hits a freezing surface. The air is warmer than the ground and has to be warm enough to carry water vapor.
8. Hail is frozen rain. It is usually the size of a pea but sometimes can be as big as a golfball.
9. Snow is a good insulator, so it can keep plants insulated from damaging sub-zero air temperatures.
10. Igloos also work on the basis of using snow as insulation. Fresh, undisturbed snow includes lots of air trapped among the snow crystals. Since the air can barely move, heat transfer is greatly reduced. Fresh, uncompacted snow typically is 90-95% trapped air.
