    Lunar trifecta: supermoon, blood moon and blue moon; NASA livestreaming

    The moon, about as large as it can be in the sky, will turn a blood red color in the hours before dawn.

    It’s a once in a ‘blue moon’ occurrence and time for the moon to take the spotlight. Following the great solar eclipse last August, serendipity will strike on Wednesday 31 January, when a total lunar eclipse is set to occur at the same time as a supermoon and blue moon.

    NASA satellite keeps track of wildfires in Argentina

    NASA’s Aqua satellite captured an image of a wildfire in La Pampa Province, on January 29, 2018.

    Roughly 12,000 wildfires burn each year in Argentina, charring more than 1.3 million hectares (5,000 square miles) of forest and grasslands. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured an image of one of them on January 29, 2018.

    Ozone hole: NASA's satellite confirms 20% less depletion; recovery by 2080

    Antarctic ozone hole forms during September in the South Hemisphere winter as returning sun’s rays catalyze ozone destruction cycles of chlorine and bromine

    Scientists have shown through direct satellite observations of the ozone hole that levels of ozone-destroying chlorine are declining. Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing man-made chemicals called chlorofluorocarbons (CFCs), has resulted in about 20% less ozone depletion during the Antarctic winter than there was in 2005, the first year that measurements of chlorine and ozone during the Antarctic winter were made by NASA's Aura satellite.

    Global surface temperatures in 2017, the second warmest since 1880, says NASA

    2017 was the third consecutive year in which global temperatures were more than 1 degree Celsius (1.8 degrees Fahrenheit) above late 19th-century levels.

    Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by scientists at NASA’s Goddard Institute for Space Studies (GISS). Continuing the planet’s long-term warming trend, globally averaged temperatures in 2017 were 0.90 degrees Celsius (1.62 degrees Fahrenheit) warmer than the 1951 to 1980 mean. That is second only to global temperatures in 2016.

    Falklands included in US universities and NASA project to keep track of kelp floating forests

    Floating Forests users have helped map kelp forests along the entire coast of California from 1984 to 2011

    Kelp forests grow along coastlines worldwide, largely hidden from view. Like rainforests, they're among the planet's most important ecosystems: beautiful but fragile habitats for a wide array of plant and animal species. But scientists believe kelp forests are being threatened by climate change. Now, researchers from UCLA and seven other universities have an improved tool for tracking these shifting ecosystems, the largest of which is about 5 miles long.

    Antarctica melting from below by some type of buried super-volcano, according to NASA research

    A geothermal heat source, a mantle plume deep below Antarctica's Marie Byrd Land, explains some of the melting that creates lakes and rivers under the ice sheet

    The Antarctic is being melted from below, according to a new study by Nasa - and a type of buried super-volcano may be to blame. The Nasa study adds evidence that there is powerful geothermal activity underneath the ice, creating lakes and rivers below the surface.

    Massive rift in Antarctica: could become the largest iceberg since 2000

    New images taken on November 10 reveal a crack in the Antarctica ice shelf that is growing in size and depth. Scientists state it will eventually break off.

    A massive rift in the Antarctica has been spotted by NASA, but the troubling details about the rift is causing the agency to worry. The ice shelf in Larsen C that is close to breaking off is as big as the size of the state of Delaware.

    Supermoon, the closest since 1948, and won't be repeated until 2034

    The moon travels in an oval-shaped orbit around Earth, but on average, the natural satellite is about 384,400 kilometers away, according to NASA.

    This month's bright supermoon — the closest full moon in 68 years — is expected to light up the sky early Monday morning, NASA has reported. Every year, scientists and sky watchers welcome the supermoon, which is the closest full moon of the year. But this year, the supermoon is receiving extraordinary attention.

    Arctic sea ice recorded its lowest maximum level on record

    The ice cover was also about 431,000 miles less than the 30-year average. Put into context, that difference is the size of Texas and California combined.

    The growth of Arctic sea ice this winter recorded the lowest maximum level on record, prompting fears of faster climate change than previously expected. Unusually warm temperatures were said to be responsible for the shrinkage.

    Last year was the hottest in modern times since 1880, shattering 2014 record

    Compared to 2014, last year was 0.29 Fahrenheit (0.13 Celsius) warmer, the “largest margin by which the annual global temperature record has been broken.”

    2015 was by far the hottest year in modern times and raising new concerns about the accelerating pace of climate change. Not only was 2015 the warmest worldwide since 1880, it shattered the previous record held in 2014 by the widest margin ever observed, said the report by the National Oceanic and Atmospheric Administration.
