The NASA Dragonfly mission will send a rotorcraft relocatable lander to the surface of Saturn's moon Titan in the mid-2030s; it will be the first mission to explore the surface of Titan.

Scientists show that 'cool' stars like the sun share dynamic surface behaviors that influence their energetic and magnetic environments. Stellar magnetic activity is key to whether a given star can host planets that support life.

Tests of glass samples gathered on Apollo missions show magnetization may result from impacts of objects like meteors, not as a result of magnetization from the presence of a magnetic shield.

Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots. Mathematicians have proposed a new model of the Sun that matches observed data.

New research has revealed the solution to Jupiter's 'energy crisis', which has puzzled astronomers for decades. Astronomers have created a detailed global map of the gas giant's upper atmosphere, confirming that Jupiter's powerful aurorae are responsible for delivering planet-wide heating.

New research provides a closer look at a nearby star thought to resemble our young Sun. The work allows scientists to better understand what our Sun may have been like when it was young, and how it may have shaped the atmosphere of our planet and the development of life on Earth.

Middle-aged stars can experience their own kind of midlife crisis, experiencing dramatic breaks in their activity and rotation rates at about the same age as our Sun, according to new research. The study provides a new theoretical underpinning for the unexplained breakdown of established techniques for measuring ages of stars past their middle age, and the transition of solar-like stars to a magnetically inactive future.

Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.

A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behavior of active regions and the nature of the solar interior.

Not a moonshot: Astronomers explore possibility of lunar observatory to better understand fundamental physics, astronomy and cosmology.

Any life identified on planets orbiting white dwarf stars almost certainly evolved after the star's death, says a new study that reveals the consequences of the intense and furious stellar winds that will batter a planet as its star is dying.

New high-resolution observations clearly show a moon-forming region around exoplanet PDS 70c. The observations have allowed astronomers to determine the ring-shaped region's size and mass for the first time.

Little is known about the weather at night on Venus as the absence of sunlight makes imaging difficult. Now, researchers have devised a way to use infrared sensors on board the Venus orbiter Akatsuki to reveal the first details of the nighttime weather of our nearest neighbor. Their analytical methods could be used to study other planets including Mars and gas giants as well.

A serendipitous flythrough of the tail of a disintegrated comet has offered scientists a unique opportunity to study these remarkable structures.

Physicists have described in fuller detail the sun's electric field. The researchers measured the flow of electrons streaming from the sun as the Parker Solar Probe spacecraft made its closest approach to date to our home star.

Last autumn, researchers reported finding the gas phosphine in trace amounts in Venus' upper atmosphere, raising the slim possibility of a biological signature. Now scientists say that the phosphine's chemical fingerprints support a different find: evidence of explosive volcanoes.

Researchers combined close-up observations of Jupiter's environment by NASA's satellite Juno, which is currently orbiting the planet, with simultaneous X-ray measurements from the European Space Agency's XMM-Newton observatory (which is in Earth's own orbit). 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.

Tidal stresses may be causing constant icequakes on Saturn's sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study.

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle. For decades, scientists argued that hit-and-run collisions blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame -- instead, the density, mass and iron content of a rocky planet's core is influenced by its distance from the sun's magnetic field.

A new analysis of Venus' surface shows evidence of tectonic motion in the form of crustal blocks that have jostled against each other like broken chunks of pack ice.
