Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.

Research reveals a shocking discovery about the history of our universe: the Milky Way Galaxy's last major collision occurred billions of years later than previously thought.

Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon composition seen to date in a protoplanetary disk, including the first extrasolar detection of ethane and a relatively low abundance of oxygen-bearing species. By including previous similar detections, this finding confirms a trend of disks around very low-mass stars to be chemically distinct from those around more massive stars like the Sun, influencing the atmospheres of planets forming there.

New partitioning coefficients of first-transition row elements, Ga and Ge between olivine and silicate melt have been reported. New high-temperature experiments have investigated the effects of oxygen fugacity and iron content on these partition coefficients. This newly compiled dataset offers insights into interpreting trace elements found in olivine phenocrysts within lunar basalts, shedding light on the deep interior composition of the Moon.

A groundbreaking method of detecting high-frequency gravitational waves (HFGWs) has been proposed. The team's innovative approach may enable the successful detection of HFGWs by utilizing existing and technologically feasible astronomical telescopes in planetary magnetosphere, opening up new possibilities for studying the early universe and violent cosmic events in an effective and technically viable way.

Scientists have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate -- slower than any of the more than 3,000 radio emitting neutron stars measured to date.

A rare exoplanet that should have been stripped down to bare rock by its nearby host star's intense radiation somehow grew a puffy atmosphere instead -- the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments. Nicknamed 'Phoenix' for its ability to survive its red giant star's radiant energy discovered planet illustrates the vast diversity of solar systems and the complexity of planetary evolution -- especially at the end of stars' lives.

Researchers call for strengthening existing planetary protection policies beyond the space surrounding Earth to include requirements for preserving the Lunar and Martian environments.

Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.

Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that can inform recent NASA missions like Insight and Perseverance and the Mars Sample Return.

Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.

Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.

The moon orbiting the asteroid Dinkinesh is actually two tiny moons stuck together. Collectively called 'Selam,' the two moonlets bring new insight into the complex processes behind planetary formation and evolution.

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.

A new study may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.

Scientists have come a step closer to identifying the mysterious origins of the 'slow' solar wind, using data collected during the Solar Orbiter spacecraft's first close journey to the Sun.

Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.
