Published Does this exoplanet have a sibling sharing the same orbit?


Astronomers have found the possible 'sibling' of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit and which, they believe, could be the building blocks of a new planet or the remnants of one already formed. If confirmed, this discovery would be the strongest evidence yet that two exoplanets can share one orbit.
Published The puzzle of the galaxy with no dark matter


New research has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology.
Published Unusual white dwarf star is made of hydrogen on one side and helium on the other



In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is made up of helium.
Published Hidden cameras spot wildlife returning home after 2018 megafire



Researchers analyzed more than 500,000 motion-sensor camera trap images taken at a Northern California reserve in the years before and after the Mendocino Complex Fire to understand how the blaze impacted small- and medium-sized mammals. The study is one of the first to compare wildlife observations made before and after a megafire, and is also one of a limited number of studies to focus on the impacts of megafires on California's oak woodlands.
Published What causes mudslides and floods after wildfires? Hint: It's not what scientists thought



Scientists once assumed that flooding and mudslides after wildfires were linked to the waxy coating that builds up on charred soil, preventing water absorption. Researchers found that water flow came from absorbed water in both burnt and unburnt areas, suggesting that water was, in fact, being absorbed into burnt ground. The discovery provides valuable insights into where and when potential flooding and mudslides may occur and how landscapes recover after a wildfire.
Published Giant swirling waves at edge of Jupiter's magnetosphere


A team has found that NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere. The waves are an important process for transferring energy and mass from the solar wind, a stream of charged particles emitted by the Sun, to planetary space environments.
Published James Webb Telescope catches glimpse of possible first-ever 'dark stars'


Three bright objects initially identified as galaxies in observations from the James Webb Space Telescope might actually represent an exotic new form of star. If confirmed, the discovery would also shed light on the nature of dark matter.
Published Rare, double-lobe nebula resembles overflowing cosmic 'jug'



A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star. The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star.
Published When the stars align: Astronomers find answers to mysterious action of ghost stars in our Galaxy



Scientists have found a source for the mysterious alignment of stars near the Galactic Center.
Published Search for dark matter



Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a storage ring COSY.
Published Fungi blaze a trail to fireproof cladding



Scientists have shown it's possible to grow fungi in thin sheets that could be used for fire-retardant cladding or even a new kind of fungal fashion.
Published New study reveals evidence of diverse organic material on Mars



Scientists gain vital insights into Mars' history and potential for supporting life.
Published Training robots how to learn, make decisions on the fly



Mars rovers have teams of human experts on Earth telling them what to do. But robots on lander missions to moons orbiting Saturn or Jupiter are too far away to receive timely commands from Earth. Researchers developed a novel learning-based method so robots on extraterrestrial bodies can make decisions on their own about where and how to scoop up terrain samples.
Published Reinventing cosmology: New research puts age of universe at 26.7 -- not 13.7 -- billion years



Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called 'impossible early galaxy problem.'
Published Addressing justice in wildfire risk management



The unequal distribution of wildfire risk in our society is influenced by various factors, such as social vulnerabilities and intersecting forms of inequality, including gender, age, ethnicity, or disability. A new article calls for more integrated and inclusive wildfire risk management approaches and proposes a novel framework mapping different justice aspects.
Published Three things to know: Climate change's impact on extreme-weather events



Researchers found that the effects of climate change on the intensity, frequency, and duration of extreme weather events, like wildfires, could lead to massive increases in all three.
Published Quasar 'clocks' show Universe was five times slower soon after the Big Bang



Quasars are the supermassive black holes at the centres of early galaxies. Scientists have unlocked their secrets to use them as 'clocks' to measure time near the beginning of the universe.
Published First 'ghost particle' image of Milky Way



Scientists have revealed a uniquely different image of our galaxy by determining the galactic origin of thousands of neutrinos -- invisible 'ghost particles' which exist in great quantities but normally pass straight through Earth undetected. The neutrino-based image of the Milky Way is the first of its kind: a galactic portrait made with particles of matter rather than electromagnetic energy.
Published Gullies on Mars could have been formed by recent periods of liquid meltwater, study suggests



A study offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on Mars.
Published Earliest strands of the cosmic web



Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This 'cosmic web' started out tenuous and became more distinct over time as gravity drew matter together.
