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.

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.

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.

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.

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.

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.

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.

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.

Scientists have found a source for the mysterious alignment of stars near the Galactic Center.

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.

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.

Scientists gain vital insights into Mars' history and potential for supporting life.

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.

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.'

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.

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.

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.

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.

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.

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.
