Science Space Photo of the Day When the lamp is shattered, The light in the dust lies dead. When the cloud is scattered, The rainbow's glory is shed. These words, which open Shelley’s poem "When the Lamp is Shattered," employ visions of nature to symbolize life in decay and rebirth. It's as if he had somehow foreseen the creation of this new Gemini Legacy image, and penned a caption for it. What Gemini has captured is nothing short of poetry in motion: the colorful and dramatic tale of a life-and-death struggle between two galaxies interacting. gliese 667c The star Gliese 667C is now the best candidate for harboring habitable worlds. Our Solar System has only one habitable planet, or maybe two if you count Mars’ past when liquid water was running on its surface. More than one potentially habitable planet per star has been a very rare event in the known stars with planets. The well-known star Gliese 581 might have two and just recently the Kepler Space Telescope discovered two in the star Kepler-62.
“The Scale Of The Universe 2″ Animation Made By 14-Year-Olds Is Mind Blowing The "Scale Of The Universe 2" is an awesome Flash animation packed with info. *UPDATE: Cary Huang, creator of “Scale Of The Universe 2″, answers some questions for the Hub. See his comments below. Ten Websites for Science Teachers We all know that the web is full of excellent web resources for science teachers and students. However, unless you live on the web, finding the best websites can become quite a challenge. This isn't a "Top Ten" list -- instead, it is a list of websites that I either use on a regular basis or just find interesting. From teaching resources for the nature of science and authentic field journals to wacky videos about numbers, I am sure that you will find something in the following list the works for you! Please share your favorite science web resources in the comment section!
Images The distant blob seen in the view on left, taken by a Hazard-Avoidance camera on NASA's Curiosity rover, may be a cloud created during the crash of the rover's descent stage. Pictures taken about 45 minutes later (right) do not show the cloud, providing further evidence it was from the crash. The bright spot at upper center, which is larger in the view at right, is due to image saturation from looking at the sun. These images are from the rover's rear Hazard-avoidance cameras. They are one-quarter of full resolution. New InSight into Martian Geology Coming in 2016 It feels like we just finished celebrating the Curiosity rover’s tremendous landing on the Martian surface. But there is no rest for the wicked. NASA has recently announced another mission to Mars scheduled to blast off in 2016.
Képler-62 Two new exoplanets discovered by NASA Kepler, Kepler-62e and Kepler-62f, were added to the Habitable Exoplanets Catalog. The two planets are part of a planetary systems of five planets around a star smaller than the Sun 1,200 light years away from Earth. Both are considered potentially habitable because they have a size not much larger than Earth and orbit within the habitable zone of their parent star. Kepler-62e is now the most Earth-like exoplanet discovered so far based on the similarity to some of its properties to Earth. However, the actual habitability of Kepler-62e and Kepler-62f depends on conditions that we can not measure yet. Another interesting planet, Kepler-69c, was also announced today but was not included in the catalog because it barely matches our habitability criteria.
Stars & Planets Scale Comparison A Humbling Perspective"Things are not what they seem, nor are they otherwise." This scale comparison shows "the true place" of Earth and our Sun among the various giants of the universe. It is simultaneously sobering and mind-boggling experience.First series of images opens with the Death Star compared to Mimas, one of Saturn's moons. Note the similarities between the two :) Designing Science Inquiry: Claim + Evidence + Reasoning = Explanation In an interview with students, MIT's Kerry Emmanuel stated, "At the end of the day, it's just raw curiosity. I think almost everybody that gets seriously into science is driven by curiosity." Curiosity -- the desire to explain how the world works -- drives the questions we ask and the investigations we conduct. Let's say that we are planning a unit on matter.
Images View Larger Image This image is the first high-resolution color mosaic from NASA's Curiosity rover, showing the geological environment around the rover's landing site in Gale Crater on Mars. The images show a landscape that closely resembles portions of the southwestern United States in its morphology, adding to the impression gained from the lower-resolution thumbnail mosaic released early in the week. Mars Has Tectonic Plates Just Like Earth Mars is like Earth in a lot of ways: It snows on the Red Planet, and a full day is a little more than 24 hours. Now, scientists have found yet another similarity. Just like Earth, Mars also has tectonic plates. For years, scientists suspected these tectonic plates existed on the Red Planet. NASA Confirms Evidence That Liquid Water Flows on Today’s Mars These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona). Vertical exaggeration is 1.5.
Remote sensing Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to in situ observation. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). It may be split into active remote sensing, when a signal is first emitted from aircraft or satellites) or passive (e.g. sunlight) when information is merely recorded.
