  Washington DC (SPX) Oct 28, 2021 How do we understand the significance of new scientific results related to the search for life? When would we be able to say, "yes, extraterrestrial life has been found?" NASA scientists are encouraging the scientific community to establish a new framework that provides context for findings related to the search for life. Writing in the journal Nature, they propose creating a scale for evaluating and combining different lines of evidence that would ultimately lead to answering the ultimate questi ... read more |

Need for Larger Space Telescope inspires lightweight flexible holographic lensTroy NY (SPX) Oct 27, 2021 Inspired by a concept for discovering exoplanets with a giant space telescope, a team of researchers is developing holographic lenses that render visible and infrared starlight into either a focused ... more  
Magnetic 'balding' of black holes saves general relativity predictionNew York NY (SPX) Oct 26, 2021 Black holes aren't what they eat. Einstein's general relativity predicts that no matter what a black hole consumes, its external properties depend only on its mass, rotation and electric charge. All ... more 
Could this be a planet in another galaxy?Huntsville AL (SPX) Oct 26, 2021 Using ESA's XMM-Newton and NASA's Chandra X-ray space telescopes, astronomers have made an important step in the quest to find a planet outside of the Milky Way. Spotting a planet in another galaxy ... more

Neutron star collisions are a "goldmine" of heavy elements, study findsBoston MA (SPX) Oct 26, 2021 Most elements lighter than iron are forged in the cores of stars. A star's white-hot center fuels the fusion of protons, squeezing them together to build progressively heavier elements. But beyond i ... more 
Astronomers provide 'Field Guide' to Exoplanets known as Hot JupitersTucson AZ (SPX) Oct 25, 2021 Hot Jupiters - giant gas planets that race around their host stars in extremely tight orbits - have become a little bit less mysterious thanks to a new study combining theoretical modeling with obse ... more 
Permafrost thaw could release bacteria and virusesParis (ESA) Oct 26, 2021 When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere and exacerbating global warming or is ... more 
Getting up to speed on the protonLemont, IL (SPX) Oct 28, 2021 Scientists develop groundbreaking theory for calculating what's happening inside a proton travelling at the speed of light. For more than 2,000 years, scientists thought the atom was the smallest pa ... more

New Horizons remains healthy and continues to send valuable data from the Kuiper Belt, even as it speeds farther and farther from Earth and the Sun. Our team has been extremely busy since I last wrote in the spring. One of the most important activities since then has been ground testing, uploading and flight-testing new software for our Alice ultraviolet spectrometer and our main (Command and Da ... more |

An intriguing candidate signal picked up last year by the Breakthrough Listen project has been subjected to intensive analysis that suggests it is unlikely to originate from the Proxima Centauri system. Instead, it appears to be an artifact of Earth-based interference from human technologies, the Breakthrough Initiatives announced Monday. Two research papers, published in Nature Astronomy, discu ... more |

 Pasadena CA (JPL) Oct 27, 2021 
Artificial intelligence, or AI, has enormous potential to change the way NASA's spacecraft study the universe. But because all machine learning algorithms require training from humans, a recent project asks members of the public to label features of scientific interest in imagery taken by NASA's Perseverance Mars rover.
Called AI4Mars, the project is the continuation of one launched last y ... more |

Earth sails the solar system in a ship of its own making: the magnetosphere, the magnetic field that envelops and protects our planet. The celestial sea we find ourselves in is filled with charged particles flowing from the Sun, known as the solar wind. Just as ocean waves follow the wind, scientists expected that waves traveling along the magnetosphere should ripple in the direction of the sola ... more |

In the heavens above, it's raining dirt. Every second, millions of pieces of dirt that are smaller than a grain of sand strike Earth's upper atmosphere. At about 100 kilometers altitude, bits of dust, mainly debris from asteroid collisions, zing through the sky vaporizing as they go 10 to 100 times the speed of a bullet. The bigger ones can make streaks in the sky, meteors that take our breath a ... more |
