  San Francisco CA (SPX) Oct 26, 2021 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, discuss both the detection of the candidate signal and an advanced data analysis process that can finely discern "f ... read 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  
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 |

Hubble gives unprecedented, early view of a doomed star's destructionBaltimore MD (SPX) Oct 25, 2021 Like a witness to a violent death, NASA's Hubble Space Telescope recently gave astronomers an unprecedented, comprehensive view of the first moments of a star's cataclysmic demise. Hubble's data, co ... more 
A radical shift to link soot formation and interstellar evolutionThuwal, Saudi Arabia (SPX) Oct 25, 2021 Rethinking the formation and growth of polycyclic aromatic hydrocarbons (PAHs), key contributors to harmful soot particles formed during fuel combustion and the smallest dust grains in interstellar ... more 
NEID Spectrometer Lights Up Path to Exoplanet ExplorationGreenbelt MD (SPX) Oct 21, 2021 As NASA expands its quest to discover exoplanets - planets beyond our solar system - it also grows its toolbox. Over the summer, a new tool called NEID (pronounced NOO-id) delivered its first batch ... 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 
Controlling light with a material three atoms thickPasadena CA (SPX) Oct 26, 2021 Most of us control light all the time without even thinking about it, usually in mundane ways: we don a pair of sunglasses and put on sunscreen, and close-or open-our window blinds. But the co ... 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 |

The Mars helicopter Ingenuity is ready for a short Martian flight as early as Saturday to test summer weather conditions that have arrived at its location on the Red Planet after two weeks of no communication because of blockage by the sun.
The flight, Ingenuity's 14th, is brief and simple by design. As weather at Jezero Crater gets warmer, the aircraft's rotors must turn faster to achi ... more |

 Boston 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 iron, scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe's heavy elements, whose formation requires more energy than a star can muster.

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 |

 Abisko, Sweden (AFP) Oct 25, 2021 
Sheltered by snow-spattered mountains, the Stordalen mire is a flat, marshy plateau, pockmarked with muddy puddles. A whiff of rotten eggs wafts through the fresh air.
Here in the Arctic in Sweden's far north, about 10 kilometres (six miles) east of the tiny town of Abisko, global warming is happening three times faster than in the rest of the world.
On the peatland, covered in tufts of ... more |
