Published Astronomers observe intra-group light -- the elusive glow between distant galaxies


Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan stars.
Published International team observes innermost structure of quasar jet


Scientists have observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world. The results suggest that the narrowing of the jet is independent of the activity level of the galaxy which launched it.
Published An exoplanet atmosphere as never seen before


New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet -- sulfur dioxide -- among other details.
Published Satellites cast critical eye on coastal dead zones


Scientists have found a new and better way to use remote sensing to understand where coastal dead zones are and predict changes.
Published Short gamma-ray bursts traced farther into distant universe


Astronomers have developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers pinpointed the galactic homes of 84 SGRBs and probed the characteristics of 69 of the identified host galaxies.
Published The tilt in our stars: The shape of the Milky Way's halo of stars is realized


New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ago.
Published Black holes in eccentric orbit


A research team has reconstructed the origin of an unusual gravitational wave signal. The signal GW190521 may result from the merger of two massive black holes that captured each other in their gravitational field and then collided while spinning around each other in a rapid, eccentric motion.
Published Elusive, dusty inner region of distant galaxy


An international team of scientists has achieved the milestone of directly observing the long-sought, innermost dusty ring around a supermassive black hole, at a right angle to its emerging jet. Such a structure was thought to exist in the nucleus of galaxies but had been difficult to observe directly because intervening material obscured our line of sight.
Published NASA's Webb catches fiery hourglass as new star forms


NASA's James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star. These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb's Near-Infrared Camera (NIRCam).
Published NASA's Webb draws back curtain on universe's early galaxies


A few days after officially starting science operations, NASA's James Webb Space Telescope propelled astronomers into a realm of early galaxies, previously hidden beyond the grasp of all other telescopes until now.
Published How does radiation travel through dense plasma?


Researchers provide experimental data about how radiation travels through dense plasmas. Their data will improve plasma models, which allow scientists to better understand the evolution of stars and may aid in the realization of controlled nuclear fusion as an alternative energy source.
Published WALLABY builds an intergalactic map in the outback


A radio telescope in remote Western Australia is helping to build a 3-dimensional map of the night sky, mapping nearby galaxies up to a billion light years away.
Published Cosmic chocolate pralines: General neutron star structure revealed


Through extensive model calculations, physicistshave reached general conclusions about the internal structure of neutron stars, where matter reaches enormous densities: depending on their mass, the stars can have a core that is either very stiff or very soft.
Published Astronomers capitalize on early access to James Webb Space Telescope data


First in line to receive data transmissions from the James Webb Space Telescope, a team of astronomers is using the unprecedentedly clear observations to reveal the secret inner workings of galaxies.
Published Safety in space: Synthetic hibernation could provide protection from cosmic radiation


It is still a glimpse into the future: Astronauts could be put into artificial hibernation and in this state be better protected from cosmic radiation. At present, there are already promising approaches to follow up such considerations. An international research team now has found decisive indications of the possible benefits of artificial hibernation for radiation resistance.
Published Study of 'polluted' white dwarfs finds that stars and planets grow together


A team of astronomers have found that planet formation in our young Solar System started much earlier than previously thought, with the building blocks of planets growing at the same time as their parent star.
Published 2400 new eyes on the sky to see cosmic rainbows


The Subaru Telescope successfully demonstrated engineering first light with a new instrument that will use about 2400 fiberoptic cables to capture the light from heavenly objects. Full operation is scheduled to start around 2024. The ability to observe thousands of objects simultaneously will provide unprecedented amounts of data to fuel Big Data Astronomy in the coming decade.
Published Searching for traces of dark matter with neutron spin clocks


An international research team has succeeded in significantly narrowing the scope for the existence of dark matter. The experiment makes an important contribution to the search for these particles.
Published Black holes don't always power gamma-ray bursts, new research shows


Space scientists may need to rethink how gamma-ray bursts are formed after new research shows new-born supramassive stars, not black holes, are sometimes responsible for these huge extragalactic bursts of energy.
Published Hubble captures three faces of evolving supernova in early universe


Three different moments in a far-off supernova explosion were captured in a single snapshot by NASA's Hubble Space Telescope. The star exploded more than 11 billion years ago, when the universe was less than a fifth of its current age of 13.8 billion years.
