This is the first time a dark spot on the planet has ever been observed with a telescope on Earth. These occasional features in the blue background of Neptune's atmosphere are a mystery to astronomers, and the new results provide further clues as to their nature and origin.

But radio observations show that the storms have long-lasting effects deeper in the atmosphere, in particular in the distribution of ammonia. Using NRAO's Very Large Array, astronomers see such impacts from storms that happened hundreds of years ago. The findings will help explain the differences between storms on the gas giants Saturn and Jupiter.

Absorption lines of hydrogen peroxide at Ganymede's poles indicate radiolysis of water ice by charged particles funneled by the moon's magnetic field. Io had two major eruptions, one associated with a forbidden emission line of sulfur monoxide. The latter supports a theory that SO is produced at volcanic vents in a thin atmosphere that allows forbidden emission before collisions destroy the excited state.

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.

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.

Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will help deepen our knowledge of how stars evolve.

The technique uses instruments on airplanes or satellites to survey large regions quickly. The upper few feet of ice sheets are important for measuring melt on Earth or looking for habitable environments on icy worlds. Previous airborne or satellite techniques could not image this narrow region in detail.

While some scientists speculated this, a research team shows that if Europa indeed formed from hydrated rocks (i.e., rocks have hydrogen and oxygen), then enough of Europa's interior should get hot enough to release water directly from the hydrated rocks to form the ocean and ice shell.

The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to radio images of Jupiter's radiation belts.

This new method promises to improve the efficiency of exoplanet searches, paving the way for the discovery of an Earth twin.

Their findings challenge long-held ideas about planet formation.

The newly discovered material's properties match those of the substance seen on the surface of icy moons, like Europa and Ganymede, and may offer clues to their icy oceans.

These observations represent the first time the previously known disk has been imaged at these infrared wavelengths of light. They also provide clues to the composition of the disk.

A team has used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region.

This could, in particular, explain the presence of oxygen in sulphur dioxide-rich atmospheres of several of Jupiter's moons. Wed, 12 Oct 2022 10:31:42 EDT //www.koonmotors.com/releases/2022/10/221012103142.htm //www.koonmotors.com/releases/2022/09/220930163205.htm Europa is more than just one of Jupiter's many moons -- it's also one of most promising places in the solar system to look for extraterrestrial life. Under 10 kilometers of ice is a liquid water ocean that could sustain life. But with surface temperatures at -180 Celsius and with extreme levels of radiation, it's also one of the most inhospitable places in the solar system. Exploring Europa could be possible in the coming years thanks to new applications for silicon-germanium transistor technology research.

If Jupiter's orbit changes, a new study shows Earth could be more hospitable than it is today.

The catch? All that water is probably embedded in the rock, rather than flowing as oceans or rivers on the surface.

What's more, the detection also suggests the presence of a very young exoplanet.

But new research shows Jupiter's massive moons prevent that vision from lighting up the night sky.

The team's near-global UV maps show concentrations of sulfur dioxide on Europa's trailing side.

The results show that the interactions of a substellar body (a planet or brown dwarf) with the hot gas in the outer envelope of a sun-like star can lead to a range of outcomes depending on the size of the engulfed object and the stage of the star's evolution. The dynamics and possible outcomes of planetary engulfment are poorly understood, but it is thought to be a relatively common fate for planetary systems.

The results suggest where to look for extraterrestrial life in the ice-covered oceans of Jupiter's moon Europa and Saturn's moon Titan.

Now, a research study has provided a new explanation of how dunes can form even on a surface as icy and roiling as Io's.

Scientists used data from Juno's payload to study the particle population traveling along the magnetic field line connecting Ganymede to Jupiter while, at the same time, remotely sensing the associated auroral emissions to unveil the mysterious processes creating the shimmering lights.

The results show that not only is the transport possible, but that the amount of oxygen brought into Europa's ocean could be on a par with the quantity of oxygen in Earth's oceans today.

This is the hottest and most massive planet-hosting star system found to date, and the planet was spotted orbiting it at 100 times the distance Jupiter orbits the Sun.

The X-rays are part of Jupiter's aurora -- bursts of visible and invisible light that occur when charged particles interact with the planet's atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but Jupiter's is much more powerful, releasing hundreds of gigawatts of energy, enough to briefly power all of human civilization.
