  San Antonio TX (SPX) Feb 25, 2021 A Southwest Research Institute (SwRI) scientist examined 11 Mars years of image data to understand the seasonal processes that create linear gullies on the slopes of the megadune in the Russell crater on Mars. In early spring images, captured by two different cameras on the Mars Reconnaissance Orbiter, SwRI's Dr. Cynthia Dinwiddie noticed airborne plumes of dusty material associated with the linear dune gullies on the sand dune's downwind slope. These clues point to active processes involving chun ... read more |

Large galaxies are known to strip the gas that occupies the space between the stars of smaller satellite galaxies.
In research published this week astronomers have discovered that these small satellite galaxies also contain less 'molecular' gas at their centres.
Molecular gas is found in giant clouds in the centres of galaxies and is the building material for new stars. Large galaxie ... more |

On Feb. 22, 1906, German astrophotographer Max Wolf helped reshape our understanding of the solar system. Again. Born in 1863, Wolf had a habit of dramatically altering the astronomy landscape.
Something of a prodigy, he discovered his first comet at only 21 years old. Then in 1890, he boldly declared that he planned to use wide-field photography in his quest to discover new asteroids, whi ... more |

Rather like David versus Goliath, it appears that Saturn's tilt may in fact be caused by its moons. This is the conclusion of recent work carried out by scientists from the CNRS, Sorbonne University and the University of Pisa, which shows that the current tilt of Saturn's rotation axis is caused by the migration of its satellites, and especially by that of its largest moon, Titan.
Recent o ... more |

Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images, whether the object in view is a single cell, the page of a book, or a far-off galaxy.
Changing focus to see clearly at all these scales typically requires physically moving a lens, by tilting, sliding, or otherwise shifting the lens, usuall ... more |

A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this 'quantum gravity' often involve mathematical corrections to Heisenberg's Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement.
These corrections arise when gravitational interactions ar ... more |

For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based facilities, including NASA's Neil Gehrels Swift Observatory, they traced the neutrino to a black hole tearing apart a star, a rare cataclysmic occurrence called a tidal disruption event.
