  Washington (AFP) Jan 24, 2020 US authorities said Friday they had granted permission to a TV provider to urgently lift a four-ton (3,600-kilogram) satellite to a so-called "graveyard orbit" over fears a battery fault may soon cause it to explode. DirecTV had told the Federal Communications Commission its Boeing-built Spaceway-1 satellite had suffered a "major anomaly" in its batteries and did not have time to deplete its remaining fuel before disposing of it by placing it 300 kilometers (190 miles) above the "geostationary arc." ... read more |

Safe to say, 2020 came in more quietly for many members of the New Horizons mission team than did 2019.
A year ago, NASA's New Horizons spacecraft flew past the Kuiper Belt object 2014 MU69 (now known as Arrokoth) in the early hours of New Year's Day, ushering in an era of exploration of the enigmatic Kuiper Belt, a region of primordial objects that holds keys to understanding the origins ... more |

Botanists have long held a fascination for heterotrophic plants, not only because they contradict the notion that autotrophy (photosynthesis) is synonymous with plants, but also because such plants are typically rare and ephemeral. However, it is still a matter of debate as to how these plants obtain nutrition.
A research team consisting of Kobe University's Associate Professor SUETSUGU Ke ... more |

 New York NY (SPX) Jan 24, 2020 
A scientific paper published in 1985 was the first to report a burgeoning hole in Earth's stratospheric ozone over Antarctica. Scientists determined the cause to be ozone-depleting substances - long-lived artificial halogen compounds. Although the ozone-destroying effects of these substances are now widely understood, there has been little research into their broader climate impacts.

Solar Orbiter will orbit our nearest star, the Sun, observing it up close. It will take the first-ever direct images of its poles, while also studying the inner heliosphere - the bubble-like region around the Sun created by the stream of energised, charged particles released in the solar wind.
At its closest, Solar Orbiter will come within about 42 million km of the Sun: closer than the sc ... more |

 Lemont IL (SPX) Jan 24, 2020 
Permafrost, the perennially frozen subsoil in Earth's northernmost regions, has been collecting and storing plant and animal matter since long before the last Ice Age. The decomposition of some of this organic matter naturally releases carbon dioxide (CO2) into the atmosphere year-round, where it is absorbed by plant growth during the warmer months.
This region, called the northern permafr ... more |

 Kiel, Germany (SPX) Jan 24, 2020 
Ocean currents are essential for the global distribution of heat and thus also for climate on earth. For example, oxygen is transferred into the deep sea through the formation of new deep water around Antarctica. Weddell Sea sourced Antarctic Bottom Water (AABW) normally spreads northwards into the South Atlantic and Indian Oceans.
However, during the peak of the last two ice ages, the sup ... more |

If you jump out of bed too quickly, you might feel a bit light-headed.
That's because when you're lying down, gravity causes your blood to pool in the lower parts of your body rather than in your brain. Fortunately, when you stand up, within a fraction of a second, your heart begins beating faster, moving the blood to your brain and allowing you to maintain your balance.
The opposite ... more |
