  NASA scientists solve mysteries of the Earth's rotation wobbling

  

  Using satellite data on how water moves around Earth, NASA scientists have solved two mysteries about wobbles in the planet's rotation - one new and one more than a century old. The research may help improve our knowledge of past and future climate.

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

  

  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

  

  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

  

  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

  

  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

  

  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

  

  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

  

  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

  

  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.
