tracylou10 Peering into the thousands of frozen layers inside Greenland’s ice sheet is like looking back in time. Each layer provides a record of what Earth’s climate was like at the dawn of civilization, or during the last ice age, or during an ancient period of warmth similar to the one we experience today. Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first-ever comprehensive map of layers deep inside the Greenland Ice Sheet.

tiagoteixeirageo Investigar as milhares de camadas de gelo da Groenlândia é como olhar para trás no tempo. Cada camada fornece um registro de como era o clima da Terra no alvorecer da civilização, ou durante a última idade do gelo, ou durante um período antigo de calor semelhante ao que experimentamos hoje. Cientistas, usando dados de radar de penetração de gelo recolhidos pela Operação IceBridge da NASA e campanhas aéreas anteriores construíram o primeiro mapa global de camadas profundas do manto de gelo da Groenlândia.

markabsher An instrument on the Solar Dynamics Observatory (SDO) captured its 100 millionth image of the sun. The instrument is the Atmospheric Imaging Assembly, or AIA, which uses four telescopes working parallel to gather eight images of the sun – cycling through 10 different wavelengths -- every 12 seconds. This is a processed image of SDO multiwavelength blend from Jan. 19, 2015, the date of the spacecraft's 100th millionth image release.

The second man to walk on the moon has lived large—and he's still at it. Buzz Aldrin, engineer and former astronaut who piloted the Lunar Module of Apollo 11 in 1969, turns 85 today. Pictured here, Aldrin (left) and fellow astronauts Charles Bassett and Theodore Freeman train in a weightless environment to simulate space conditions as part of their @nasa mission training for Gemini 12 in 1964.

The year 2014 now ranks as the warmest on record since 1880, according to an analysis by NASA scientists.

Nine of the 10 warmest years since modern records began have now occurred since 2000, according to a global temperature analysis by scientists at NASA’s Goddard Institute for Space Studies in New York. "Easy explanation, Women are to blame, they keep getting hotter and hotter..."

leantorresr NASA's Hubble Space Telescope has revisited the famous Pillars of Creation, revealing a sharper and wider view of the structures in this visible-light image.

Astronomers combined several Hubble exposures to assemble the wider view. The towering pillars about are 5 light-years tall. The new image was taken with Hubble's versatile and sharp-eyed Wide Field Camera 3.

The pillars are bathed in blistering ultraviolet light from a grouping of young, massive stars located off the top of the image. Streamers of gas can be seen bleeding off the pillars as the intense radiation heats and evaporates it into space. Denser regions of the pillars are shadowing material beneath them from the powerful radiation. Stars are being born deep inside the pillars, which are made of cold hydrogen gas laced with dust. The pillars are part of a small region of the Eagle Nebula, a vast star-forming region 6,500 light-years from Earth.

The colors in the image highlight emission from several chemical elements. Oxygen emission is blue, sulfur is orange, and hydrogen and nitrogen are green.

This image taken from the Suomi NPP satellite's VIIRS instrument of New Zealand was collected on January 9, 2015 when the phytoplankton were blooming — particularly to the east of the islands and along the Chatham Rise.

Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.

Phytoplankton growth depends on the availability of carbon dioxide, sunlight, and nutrients. Phytoplankton, like land plants, require nutrients such as nitrate, phosphate, silicate, and calcium at various levels depending on the species. Some phytoplankton can fix nitrogen and can grow in areas where nitrate concentrations are low. They also require trace amounts of iron which limits phytoplankton growth in large areas of the ocean because iron concentrations are very low. Other factors influence phytoplankton growth rates, including water temperature and salinity, water depth, wind, and what kinds of predators are grazing on them.

When conditions are right, phytoplankton populations can grow explosively, a phenomenon known as a bloom. Blooms in the ocean may cover hundreds of square kilometers and are easily visible in satellite images. A bloom may last several weeks, but the life span of any individual phytoplankton is rarely more than a few days.

q8williamwallacq8 وقد تم جمع هذه الصورة مأخوذة من VIIRS أداة القمر الصناعي سومي NPP في نيوزيلندا على 9 يناير 2015 عندما العوالق النباتية وتتفتح - ولا سيما إلى الشرق من الجزر وعلى طول صعود تشاتام.

مشتقة من الكلمات اليونانية النباتية (النباتات) والعوالق (المبذولة ليهيمون على وجوههم أو الانجراف)، العوالق النباتية هي كائنات المجهرية التي تعيش في البيئات المائية، سواء المالحة والعذبة.

يعتمد نمو العوالق النباتية على توافر ثاني أكسيد الكربون، وضوء الشمس، والمواد المغذية. العوالق النباتية، مثل النباتات البرية، تتطلب المواد المغذية مثل النترات والفوسفات والسيليكات، والكالسيوم على مختلف المستويات تبعا للأنواع. بعض العوالق النباتية يمكن إصلاح النيتروجين ويمكن أن تنمو في المناطق التي توجد فيها تركيزات النيترات منخفضة. فهي تتطلب أيضا على كميات ضئيلة من الحديد الذي يحد من نمو العوالق النباتية في مناطق واسعة من المحيط بسبب تركيزات الحديد منخفضة جدا. وهناك عوامل أخرى تؤثر على معدلات نمو العوالق النباتية، بما في ذلك درجة حرارة المياه والملوحة وعمق المياه والرياح، وأنواع من الحيوانات المفترسة والرعي عليها.

عندما تتوفر الظروف الملائمة، يمكن أن تنمو السكان العوالق النباتية متفجرات، وهي ظاهرة تعرف باسم ازهر. تزهر في المحيط قد تغطي مئات الكيلومترات المربعة وتكون مرئية بسهولة في صور الأقمار الصناعية. وازهر قد تستمر عدة أسابيع، ولكن العمر الافتراضي للأي العوالق النباتية الفردية ونادرا ما أكثر من بضعة أيام.
