When we don’t have spectra, we can estimate the distance to a quasar by calculating its photometric redshift. Today’s authors present a new way to use the ‘flickering’ of quasars to improve these distance estimates.
How do you produce ultra-high-energy neutrinos like KM3-230213A? Guest author Domenik Ehlert explains how cosmic rays may be behind it!
The Infinity Galaxy might be home to a newborn supermassive black hole that formed directly from a gas cloud instead of a star. Could this help reveal how these objects formed in the early universe?
JWST liked it so much it put two rings on it: a pair of dying stars dance at the heart of this spectacular nebula that is enriching the Galaxy.
JWST’s discovery of free-floating binary planetary-mass objects came as quite a surprise and tests theories of planet formation. Today’s paper investigates whether dynamical encounters in dense star-forming regions could destroy such binary systems.
When stars are born, they’re hidden behind dust and dense gas. How long will it take them to emerge?
