If you are adventurous and like adrenaline rushes, then have you considered starting off the New Year with a polar bear plunge? “Polar Bear Swims”, “Plunges”, or “Dips”, are a New Year’s Day tradition in numerous countries. Thousands upon thousands of brave souls race toward the icy cold water and then make a mad dash back out. In the USA, folks are freezin’ for a reason as most polar bear plunges are to raise money for a charitable organizations. In Canada and the Netherlands, polar bear plunges are associated with New Year’s Day. 36,000 people participated in ‘Nieuwjaarsduik’, New Year’s dive, January 1st 2012 in the Netherlands. Since 1960, every New Year’s Day, at least 10,000 people dive collectively into the icy cold sea water at Scheveningen which is the Netherlands’ main beach resort town. While New Year’s Day is not the only day for taking up such an extreme sport, for some it is Superbowl Sunday, one thing is the same worldwide for people in polar bear swims . . . the look of shocked faces as if they cannot believe the water is that cold or that they took part in a polar bear plunge. Whether it’s brave, stupid, or simply invigorating, kudos to all those folks! [50 Photos]

If you approached the rim of a volcano and looked down into it, you might expect to see a lava pool, but if the volcano previously erupted and then the top of it collapsed into a huge bowl-shaped crater, or caldera, then what you might see when you peer over the rim is a beautiful crater lake. Sometimes the water is acidic and the lake has a bright greenish hue. Other times the water is a cloudy turquoise color, yet other times the lake may appear to be a very deep shade of blue. Crater Lake, Oregon, is one of the most well known, but crater lakes can be found all over the globe. If the volcano has been dormant for a long time, the water can be extremely clear because no river or streams flow into with sediment deposits. In some cases, water may have filled up an impact crater to form a lake, but this is less common. A few crater lakes were created by man via an atomic blast, but an artificially-created crater lake is the least common of all. All crater lakes were once a place where the earth experienced great violence, but now are a place of great beauty . . . even though the volcano can become active and violent again. Here are 44 photos of 42 of the world’s most beautiful crater lakes. [44 Photos]

As Charles Schulz, the American cartoonist for Peanuts, said, “Christmas is doing a little something extra for someone.” So here are 40 fantastic Christmas-themed snowy scenes captured for an eternity in globes of water. If you are still wondering about a present for someone, perhaps you will be inspired by Oren Arnold who said, “Christmas gift suggestions: To your enemy, forgiveness. To an opponent, tolerance. To a friend, your heart. To a customer, service. To all, charity. To every child, a good example. To yourself, respect.”

NASA has shown us views of the Big Marble, the breathtakingly beautiful planet on which we live because it studies space and the Earth. The first Big Blue Marble photo was released in 1972 and each subsequent release of images have increased in quality so that the newest 2012 release of the Big Black Marble, or Earth at Night, are stunning. The Suomi National Polar-orbiting Partnership (NPP) satellite was launched last year by NASA, NOAA, and the Department of Defense. It orbits 512 miles above our planet’s surface and has an extremely sensitive sensor that can detect the nocturnal glow produced by Earth’s atmosphere. In fact, it can see the light given off from a single street light or one glowing light on a boat floating alone on the ocean. The VIIRS (Visible Infrared Imaging Radiometer Suite) “carries a low-light sensor that can distinguish night lights with six times better spatial resolution and 250 times better resolution of lighting levels (dynamic range) than before.” NASA added, “A global composite image, constructed using cloud-free night images from a new NASA and National Oceanic and Atmospheric Administration (NOAA) satellite, shows the glow of natural and human-built phenomena across the planet in greater detail than ever before.” So here is the series of the Big Marble in Old, New, Aqua, Blue, White and Black Marble. If you stop to think that this is our home, all of us regardless of where on the globe you are located, then it somehow seems possible that we could achieve peace on Earth around this holiday season for Christmas, Hanukkah, Kwanzaa, and Boxing Day. It also shows why we should protect our environment . . . it belongs to your children’s children and us all. Thank you NASA! You ROCK! [22 Photos, 2 Videos]

Wow! NASA has released a holiday treasure in the form of a free “Earth As Art“ ebook that contains 75 stunning images. If you haven’t downloaded it yet, then what are you waiting for? The Earth Science Division of NASA Science Mission Directorate wrote, “In 1960, the United States put its first Earth-observing environmental satellite into orbit around the planet.” These images of Earth were captured with “the Terra, Landsat 5, Landsat 7, EO-1, and Aqua satellites. Sensors on these satellites can measure light outside of the visible range, so the images show more than what is visible to the naked eye.” These images are so beautiful that it will blow your mind. We really don’t know how anyone could resist loving NASA. Their book “celebrates Earth’s aesthetic beauty in the patterns, shapes, colors, and textures of the land, oceans, ice, and atmosphere. The beauty of Earth is clear, and the artistry ranges from the surreal to the sublime.” Here are 28 absolutely great satellite photos showcasing the art of our planet Earth. [28 Great Photos]

For people who are animal penguin lovers, besides Tux lovers, here are the tuxedo-wearing waddlers that dwell primarily in Antarctica. While penguins don’t fly, they can spend as much as 75% of their time at sea. All penguins give birth to their chicks on land or on sea ice. Because penguins so incredibly cute, they are often depicted on holiday ornaments and in happy animation movies. We love these penguin pics! [41 Photos]

In fact, there are tributes to the Tux mascot via food, toys, and even from a few future Linux hacker babies. Tux inspires art like digital wallpapers as well as Tux graffiti. We’ll toss in a few interesting Linux facts and hopefully dear Linux lovers, you will at least smile and remember that it’s the thought that counts? Smile and have a great day! [69 Pics]
