New research has revealed how temperatures in Neptune's atmosphere have unexpectedly fluctuated over the past two decades.

New research shows how the impact that created the Moon's South Pole -- Aitken basin is linked to the stark contrast in composition and appearance between the two sides of the Moon.

Researchers are investigating the psychological impact of social isolation in harsh environments, such as on the Moon.

Scientists have built instruments to give humans eyes and a nose on Mars -- and now they are helping add ears as well.

On November 8, 2020, NASA's Juno spacecraft flew through an intense beam of electrons traveling from Ganymede, Jupiter's largest moon, to its auroral footprint on the gas giant. 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.

An international research team has discovered a new planet so young that it has yet to emerge from the womb of matter where it is forming. This is the youngest protoplanet discovered to date. It's location and the surrounding patterns of matter suggest that an alternative method of planet formation may be at work. This discovery could help to explain the histories and features of extrasolar planets seen around other stars.

NASA's Perseverance rover, which has been surveying the surface of Mars since February 2021, has for the first time recorded the acoustic environment of the Red Planet.

An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere.

Newly discovered deposits of layered ice in craters scattered around Mars' southern hemisphere provide insights into how the planet's orientation controlled the planet's climate over the past 4 million years, according to a new study. The findings help scientists understand what controlled Mars' past climate, which is essential for predicting when the planet could have been habitable.

Researchers have built the world's first physics-based computer simulation of oxygen transport on Europa, finding that it's possible for oxygen to drain through the moon's icy shell and into its ocean of liquid water -- where it could potentially help sustain alien life -- by hitching a ride on salt water under the moon's 'chaos terrains.' 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.

The further we move away from a heat source, the cooler the air gets. Bizarrely, the same can't be said for the surface of the Sun, but scientists may have just explained a key part of why.

Astronomers identified a nearby star whose sunspot cycles appear to have stopped. Studying this star might help explain the unusual period from the mid 1600s to the early 1700s when our Sun paused its sunspot cycles.

Among thousands of known exoplanets, astronomers have flagged three that are actually stars.

Researchers have recently discovered a breakthrough in magnetic reconnection that could ultimately help predict space weather.

Many coronal loops -- ropey strands of plasma that scientists have long thought existed in the sun's atmosphere -- may actually be optical illusions, according to a new paper that challenges prevailing assumptions of what we know, and don't know, about the sun.

Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solar astronomy and other fields such as plasma physics, fusion science, and fluid dynamics.

Scientists have today provided more insight into the possibility of establishing a pathway to generate oxygen for humans to potentially call the Moon or Mars 'home' for extended periods of time.

It has long been known that Mars once had oceans due in part to a protective magnetic field similar to Earth's. However, the magnetic field disappeared, and new research may finally be able to explain why. Researchers recreated conditions expected in the core of Mars billions of years ago and found that the behavior of the molten metal thought to be present likely gave rise to a brief magnetic field that was destined to fade away.

Space scientists have discovered a never-before-seen mechanism fueling huge planetary aurorae at Saturn.

Astronomers have identified two different cases of 'mini-Neptune' planets that are losing their puffy atmospheres and likely transforming into super-Earths.
