  Boston MA (SPX) Nov 02, 2021 Planets and their stars form from the same reservoir of nebular material and their chemical compositions should therefore be correlated but the observed compositions of planets do not match completely those of their central stars. In our Solar system, for example, all the rocky planets and planetesimals contain near-solar proportions of refractory elements (elements like aluminum that condense from a gas when the temperature falls below about 1500 kelvin) but are depleted in volatile elements (tho ... read 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 |

 Washington DC (UPI) Oct 28, 2021  The link that early anthropologists hoped would neatly bridge the gap between apes and humankind probably doesn't exist, most scientists now agree. Human evolution, it turns out, looks more like a "braided stream" of diverging and converging lineages than an inclined plane of slowly improving posture.
To map this braided stream, one group of researchers urge a closer look at Middle Plei ... more |
