Chandra Detects ‘Sonic Boom’ from Powerful Kilonova

Mar 3, 2022 by News Staff

The binary neutron-star merger GW170817 was discovered in August 2017. Many telescopes saw different kinds of light after the discovery, but only NASA’s Chandra X-ray Observatory is still making a detection. Early Chandra data revealed the presence of a narrow jet that has slowed down and expanded over time. The new study presents X-ray evidence for a shock — similar to a sonic boom — in the aftermath of the neutron-star merger. An artist’s...

Noise variations in the two regions covered by the second data release from the LOw-Frequency ARray (LOFAR) Two-metre Sky Survey with the coverage of the 841 individual pointing outlined. The RA-13 (top) and RA-1 (bottom) regions span 4,178 and 1,457 square degrees and have median rms values of 74 μJy beam−1 and 106 μJy beam−1 respectively. Failed facets (white regions) are generally caused by either poor ionospheric conditions or dynamic range issues around bright sources such as 3C 48 and 3C 196.

This Hubble image shows the galaxy pair NGC 4496. The color image is composed of infrared, optical and ultraviolet observations from Hubble’s Wide Field Camera 3 (WFC3), the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope, and the Sloan Digital Sky Survey (SDSS). Nine filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / T. Boeker / B.

You et al. shows that meat intake is positively associated with life expectancy at national level; the underlying reasons may be that meat not only provides energy but also complete nutrients to human body; from the evolutionary point of view, meat has arguably been an indispensable component in human diet for millions of years, which is evidenced, genetically, by meat digesting enzymes and digestive tract anatomy; the complete nutritional profile of meat and human adaptation to meat eating have enabled humans to gain many physical benefits, including greater life expectancy; meat intake, or its adequate replacement, should be incorporated into nutritional science to improve human life expectancy.

Four possible domains of planetary intelligence: (a) on a planet with an immature biosphere (such as the Earth during the Archean Eon) there are insufficient feedback loops between life and geophysical coupled systems to exert strong co-evolution; (b) on a planet with a mature biosphere (such as Earth after the Proterozoic) the biosphere exerts strong forcing on the geophysical state establishing full co-evolution of the entire system; this feedback may provide some degree of long-term stabilizing (i.e. Gaian) modulations for the full system; (c) on a planet with an immature technosphere (represented by the current Anthropocene Earth) feedbacks from technological activity produce strong enough forcing on the coupled planetary system to drive it into new dynamical states; these forcings however are unconstrained by intention relative to the health of the civilization producing the technology; (d) on a planet with a mature technosphere, feedback loops between technological activity and biogeochemical and biogeophysical states have been intentionally modified to ensure maximum stability and productivity of the full system; alongside each planetary image, we show a schematic atmospheric spectrum; an immature biosphere would show an atmosphere mostly in equilibrium dominated perhaps by carbon dioxide (CO2); in a mature biosphere life would have changed atmospheric chemistry leading to a highly non-equilibrium state such as perhaps high concentrations of oxygen (O2); in an immature technosphere new ‘pollutant’ species appear, such as CFCs, while industrial activities such as combustion may alter the abundance of other pre-existing gases like CO2 and methane; in a mature technosphere all atmospheric constituents may have their concentrations modified to produce long-term stable and productive states for the full (civilization + biosphere) system; this is represented via a range of possible peaks for different constituents.
