Published Oldest planetary debris in our galaxy found from new study
(via sciencedaily.com) Original source Astronomers have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way.
Published First glimpse of what gravity looks like on cosmological scales
(via sciencedaily.com) Scientists have reconstructed gravity to find a more robust way of understanding the cosmos.
Published IceCube neutrinos give us first glimpse into the inner depths of an active galaxy
(via sciencedaily.com) Scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date.
Published Uncovering the massive quantum mysteries of black holes
(via sciencedaily.com) Bizarre quantum properties of black holes -- including their mind-bending ability to have different masses simultaneously -- have been confirmed by physicists.
Published Rare Earth elements synthesis confirmed in neutron star mergers
(via sciencedaily.com) When two neutron stars merge, the resultant explosion forms heavy elements -- many of which make up our Universe. A new study has identified the specific rare-earth elements produced in a neutron star merger.
Published Cosmic rays drive galaxy's winds
(via sciencedaily.com) VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic evolution, particularly at earlier times in the history of the universe.
Published Using carbon-carbon clumping to detect the signature of biotic hydrocarbons
(via sciencedaily.com) The mystery of the origin of hydrocarbons found in extraterrestrial environment may finally be resolved, thanks to a technique based on a 13C-13C abundance analysis. By measuring the abundance of clumped 13C-13C isotope in the hydrocarbons, it can be inferred if a hydrocarbon was produced via biological processes. This could open doors to distinguishing such hydrocarbons from abiotic ones, aiding our search for extra-terrestrial life.
Published Unprecedented glimpse of merging galaxies
(via sciencedaily.com) Original source Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe.
Published NASA's Webb takes star-filled portrait of pillars of creation
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has captured a lush, highly detailed landscape -- the iconic Pillars of Creation -- where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear -- at times -- semi-transparent in near-infrared light.
