  Los Alamos NM (SPX) Jan 15, 2020 Nine sources of extremely high-energy gamma rays comprise a new catalog compiled by researchers with the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. All produce gamma rays with energies over 56 trillion electron volts (TeV) and three emit gamma rays extending to 100 TeV and beyond, making these the highest-energy sources ever observed in our galaxy. The catalog helps to explain where the particles originate and how they are accelerated to such extremes. "The Earth is constantly bei ... 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 |

 Stanford CA (SPX) Jan 14, 2020 
Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky. They found that this light is brighter in regions that contain a lot of matter and dimmer where matter is sparser - a correlation that could help them narrow down the properties of exotic astrophysical objects and invisible dark matter.
The glow, known as unresolved gam ... more |

Deep below the Earth's surface lies a thick rocky layer called the mantle, which makes up the majority of our planet's volume. While Earth's mantle is too deep for humans to observe directly, certain meteorites can provide clues to this unreachable layer.
In a study recently published in Science Advances, an international team of scientists, including Sang-Heon Dan Shim and Thomas Sharp of ... more |

 Chicago IL (SPX) Jan 14, 2020 
Stars have life cycles. They're born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for millions to billions of years, and then they die. When they die, they pitch the particles that formed in their winds out into space, and those bits of stardust eventually form new stars, along with new planets and moons and meteorites. And ... more |

 Tempe AZ (SPX) Jan 14, 2020 
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 |
