An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed.
This rare supernova, called 2023ufx, originated from the core collapse of a red supergiant star, exploded on the outskirts of a nearby dwarf galaxy. Results of the study showed that observations of both this supernova and the galaxy it was dis NASA selects SpaceX for Dragonfly mission to Titan

NASA has officially awarded SpaceX the contract to provide launch services for its highly anticipated Dragonfly mission, part of the New Frontiers Program. This innovative mission will send a rotorcraft lander to Titan, Saturn's largest moon, to explore its unique geologic settings and search for clues about the origins of life.

The universe just got a whole lot bigger - or at least in the world of computer simulations, that is.
In early November, researchers at the Department of Energy's Argonne National Laboratory used the fastest supercomputer on the planet to run the largest astrophysical simulation of the universe ever conducted.
The achievement was made using the Frontier supercomputer at Oak Ridge Nat XRISM mission looks deeply into 'hidden' stellar system

The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has captured the most detailed portrait yet of gases flowing within Cygnus X-3, one of the most studied sources in the X-ray sky.
Cygnus X-3 is a binary that pairs a rare type of high-mass star with a compact companion - likely a black hole.
"The nature of the massive star is one factor that makes Cygnus X-3 so HESS Observatory identifies highest-energy cosmic-ray electrons and positrons yet observed

Scientists from CNRS, a German university consortium, and the Max-Planck-Institut fur Kernphysik working at the H.E.S.S. Observatory in Namibia have detected cosmic-ray electrons and positrons with the highest energies ever recorded, exceeding 40 TeV. This significant discovery reveals new insights into cosmic processes that produce immense energy, although their origins remain unclear.

Eclipse-maker: How Proba-3 subtracts the Sun

Hidden in plain sight within the Sun’s glare is the ultra-hot yet ghostly faint solar corona, source of the solar wind and solar storms. The only way to see this key element of the Solar System is either through the remarkable cosmic coincidence that gives rise to total solar eclipses – the fact that the Sun is not only 400 times bigger than our Moon but also about 400 times further away, allowing it to cover the solar disc entirely – or else through artificial Sun-obscuring telescopes.
