Most Close Pairs of Stars Are Born as Cosmic Twins
2+ hour, 30+ min ago (460+ words) Many stars in our galaxy don't live alone like the Sun. Roughly half of Sun-like stars are part of a pair or even a small family of stars that orbit each other. Young stars are even more likely to have…...

2+ hour, 35+ min ago (169+ words) astrobiology. com As Above, Not So Below: Ion Fractionation In Planetary Analog Ices The geophysical evolution and astrobiological potential of ocean worlds are indelibly linked to the chemical compositions of their oceans and ice shells. In the absence of direct…...
The Master Molecule That Built Biology: How Water Shaped The Chemistry Of Life
2+ hour, 54+ min ago (173+ words) The deep entanglement of biomolecular structure and function with aqueous systems supports the view that water actively sculpted both molecules and processes during the origins of life and continues to constrain evolution today. Nature's rules of biochemistry and biophysics have…...
In Situ Analytical Chemistry Laboratory for the Exobiology Extant Life Surveyor
2+ hour, 45+ min ago (188+ words) astrobiology. com In Situ Analytical Chemistry Laboratory for the Exobiology Extant Life Surveyor In this paper, we report a fully automated, end-to-end (sample-in/data-out) capillary electrophoresis system. The system's dimensions conform to the cylindrical shape and power/data requirements of…...
LMA Observations Of Acetone In Hot Cores
1+ day, 2+ hour ago (258+ words) Acetone (CH3 COCH3) is a ubiquitous interstellar molecule, and serves as an important tracer of hot core chemistry. We conducted a line survey of acetone and its precursor acetaldehyde (CH3 CHO) towards 60 hot cores by using the ALMA 3 mm lines observations. We calculated…...
