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.

They propose a new scientific subfield: planetary geoarchaeology, the study of how cultural and natural processes on Earth's moon, on Mars and across the solar system may be altering, preserving or destroying the material record of space exploration.

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.

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.

This image serves as context for an observing program that will test the telescope's capacity to detect faint moons around the planet and its bright rings. Any newly discovered moons could help scientists put together a more complete picture of the current system of Saturn, as well as its past.

Mysteries surrounding the origin of the Geminids have long fascinated scientists because, while most meteor showers are created when a comet emits a tail of ice and dust, the Geminids stem from an asteroid -- a chunk of rock that normally does not produce a tail. Until now, this unusual meteoroid stream had only been studied from Earth.

A team of scientists has discovered new evidence that the subsurface ocean of Saturn's moon Enceladus contains a key building block for life. The team directly detected phosphorus in the form of phosphates originating from the moon's ice-covered global ocean using data from NASA's Cassini mission. Cassini explored Saturn and its system of rings and moons for over 13 years.

The researchers concluded that the planet's rings formed less than 400 million years ago, making them much younger than Saturn itself.

It brightens and forms a tail when it's near the Sun, and it is the source of the annual Geminid meteor shower, even though comets are responsible for most meteor showers. Scientists had blamed Phaethon's comet-like behavior on dust escaping from the asteroid as it's scorched by the Sun. However, a new study using two NASA solar observatories reveals that Phaethon's tail is not dusty at all but is actually made of sodium gas.

The computational framework takes in information about the rocket, its engines, and the surface composition and topography, as well as the atmospheric conditions and gravitational forces at the landing site, and the results can be used to evaluate the safety and feasibility of a proposed landing site and to optimize the design of spacecraft and rocket engines for planetary landings.

The tail of particles that form can help determine the physical characteristics of the asteroid. NASA's Double Asteroid Redirection Test mission in September 2022 gave a team of scientists a unique opportunity -- to observe the evolution of an asteroid's ejecta as it happened.

This experiment was to test a potential technique to someday deflect an asteroid on a collision course to Earth. Perhaps, for the first time in the history of the universe, an intelligent planetary species sought ways to avoid its own potential extinction by threats from outer space (something the dinosaurs, who were wiped out 65 million years ago by a rogue asteroid, never evolved to accomplish).

Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus' core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.

They have been observed in the years preceding and following the planet's equinox, becoming more prominent as the date approaches. Saturn's upcoming autumnal equinox of the northern hemisphere on May 6, 2025, means that spoke season has come again. NASA's Hubble Space Telescope will be on the job studying the spokes, thanks to time dedicated to Saturn in the mission's ongoing Outer Planet Atmospheres Legacy (OPAL) program. Are the smudgy features related to Saturn's magnetic field and its interaction with the solar wind, as prevailing theory suggests? Confirmation could come in this spoke season, as scientists combine archival data from NASA's Cassini mission with new Hubble observations.

This marks humanity's first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology.

The Japanese space probe Hayabusa 2 had collected the samples. Geoscientists have now discovered areas with a massive accumulation of rare earths and unexpected structures.
