PIX4613167: Spiral galaxy NGC 7331 in Pegase - Spiral galaxy NGC 7331 in Pegasus: The galaxy NGC 7331 is located about 45 million light years away from Earth. Image obtained with the Hubble Space Telescope. NGC 7331 is located about 45 million light-years away in the constellation of Pegasus (The Winged Horse). Facing us partially edge-on, the galaxy showcases it's beautiful arms which swirl like a whirlpool around its bright central region. Astronomers took this image using Hubble's Wide Field Camera 3 (WFC3), as they were observing an extraordinary exploding star - a supernova - which can still be faintly seen as a tiny red dot near the galaxy's central yellow core. Named SN2014C, it rapidly evolved from a supernova containing very little Hydrogen to one that is Hydrogen-rich - in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. NGC 7331 is similar in size, shape, and mass to the Milky Way. It also has a comparable star formation rate, hosts a similar number of stars, has a central supermassive black hole and comparable spiral arms. The primary difference between our galaxies is that NGC 7331 is an unbarred spiral galaxy - it lacks a “” bar”” of stars, gas and dust cutting through its nucleus, as we see in the Milky Way. Its central bulge also displays a quirky and unusual rotation pattern, spinning in the opposite direction to the galactic disc itself / Bridgeman Images

PIX4632110: Earth by Apollo 17 - View of the Earth seen by Apollo 17 - La terre vue par Apollo 17 le 07/12/1972. View of the Earth as seen by the Apollo 17 crew traveling towards the moon. This translunar coast photograph extends from the Meditierranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the southern hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is the Malagasy Republic. The Asian mainland is on the horizon towards the northeas / Bridgeman Images

PIX4632421: Hottest surface temperatures between 2003 and 2005 - Hottest land surface temperatures between 2003 and 2005 - Map obtained from data collected by the Aqua satellite using the MODIS instrument from 2003 to 2005. The scale ranges from 10 degres to 70 degres celsius; the hottest spots appear in white then in light pink, in purple the temperate regions, in blue the coldest regions. According to this report, the warmest temperature recorded between 2004 and 2005 was 70.7 degres in the Lut desert in Iran. In 2003, Australia in Queensland had the warmest temperature at 69.3 degres. This image shows the hottest land surface temperature instrument MODIS on Aqua satellite recorded at each location on Earth between 2003 and 2005. The hottest places, shown in light pink, are barren or sparsely vegetated deserts. These areas dominate northern Africa, southern Asia, Australia, and parts of western North and South America. Densely vegetated areas such as the Amazon and Congo rain forests of South America and Africa and the boreal forests of North America and Eurasia are much cooler, showing up as purple. Cooler yet, in blue, are high elevations like the Tibetan Plateau and mountain ranges. The coldest locations are the ice - capped lands near the North and South Poles. According to MODIS, the hottest place in 2004 and 2005 was the Lut desert of Iran, which reached 70.7 degrees C (159 degrees F). In 2003, Queensland, Australia, was the hottest place on Earth, with a temperature of 69.3 degrees C (157 degrees F) / Bridgeman Images
PIX4632425: Earth: biosphere map - Global Biosphere - Map of mean concentration of chlorophyll and vegetation between 1997 and 2000. It is with great pleasure that the Sea - viewing Wide Field - of - view Sensor (SeaWIFS) Project announces that September 18, 2000, was the third anniversary of the start of SeaWIFS observations of this remarkable planet called Earth. This SeaWIFS image of our world depicts the global biosphere - - the ocean's long - term average phytoplankton chlorophyll concentration acquired between September 1997 and August 2000 combined with the SeaWIFS - derived Normalized Difference Vegetation Index over land during July 2000. This image shows where there is more or less plant life on our planet. On land, the dark greens show where there is abundant vegetation and tans show relatively sparse plant cover. In the oceans, red, yellow, and green pixels show dense phytoplankton blooms while blues and purples show where there is very little of the microscopic marine plant / Bridgeman Images
PIX4632429: November 2007 Temperature Map - Land surface temperatures in november 2007 - Map of average temperatures observed on Earth's surface by the Terra satellite between November 1 and December 1, 2007. The coldest regions appear in blue and white, the warmest in yellow and red. Moderate Resolution Imaging Spectroradiometer (MODIS) flying on NASA's Terra satellite between November 1 and December 1, 2007.

PIX4632690: Primitive Earth - Artist's View - Ancient terrestrial landscape - Artist's view of the Earth about 4 billion years ago. Volcanoes dominate the landscape. This is how the surface of the Earth may have appeared beneath its clouds about 500 million years after its birth. Massive volcanoes and lava fields still dominate the landscape. In a few million years rain will begin falling, further cooling the crust. In about another 200 million years the first living microbes will call the Earth home / Bridgeman Images

PIX4633177: 100m ocean level rise - Asia - Asia with sea level+100m - Artist's view showing Asia as it would appear if ocean level increased by 100 metres. This would happen if all glaciers on Earth melt. This is how Asia may appear with mean sea level about 100 meters (330 feet) above today's. Such a dramatic rise in sea level could occur if all of the Earth's glaciers were to melt. In this image the Gulf of Thailand now cleaves that country in two while submerging almost all of Cambodia. The Gulf of Tonkin has claimed much of North Viet Nam. Ocean waters have claimed much of South Korea and some of North Korea and Eastern China. To the south much of Malaysia and the Indonesian archipelago have been claimed by the higher waters / Bridgeman Images
