Testing cosmology with the DES 5-year supernovae dataset
In today’s astrobite, we discuss the results of the cosmology analysis for the Dark Energy Survey, from it’s 5 year supernovae dataset.

Do magnetars have flux ropes that look like giant muscular arms? No, but they have some magnetic arches with the muscle to rip light apart!
Venus may be quite similar in size and mass as Earth, but its surface conditions could not be any more different! Can a modern space telescope like JWST identify the difference between an exoEarth and an exoVenus?
Today’s authors analyze the time delay between energetic flares coming from a black hole x-ray binary system, and try to determine if this is evidence of a magnetic process occuring in the accretion disk.
Signs of life on other worlds might be detectable with today’s instruments – but can JWST detect the signs of conditions where life could form? Today’s authors try to answer this question.
Today’s paper describes the brightest ever gamma-ray burst, as seen in very-high-energy gamma-rays by LHAASO.
