Already 26 million km (16 million miles) from Earth, NASA’s Psyche spacecraft will arrive at its target asteroid Psyche in 2029. The Psyche team wanted...
Enceladus is a prime target in the search for life in the Solar System, identified by NASA as the second-highest priority site for a flagship mission in...
The trans-Neptunian dwarf planet Eris is tidally locked to its small moon Dysnomia. Recently obtained bounds on the mass of Dysnomia demonstrate that Eris...
As part of the Thor-Davis experiment on the International Space Station (ISS), ESA astronaut Andreas Mogensen has captured images of a phenomenon called...
In an operation that took mission scientists three months to plan, NASA’s Mars Odyssey orbiter captured a series of panoramic images that showcases the...
Astronomers have long puzzled over why all of the planets in our Solar System have slightly slanted orbits around the Sun. But Yale University planetary...
Using satellite observations, including from ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, and a new developed analytical...
A few decades ago, seismologists identified a thin layer with a lower velocity in Earth’s metallic liquid core. The origin of this layer, known as the...
The atmospheric nightglow is observed on Earth. On Mars, it was something expected, yet never observed in visible light until now.
This image shows an...
Atomic oxygen is produced on the dayside of Venus by photolysis of carbon dioxide and carbon monoxide.
Atomic oxygen is a key species in the mesosphere...
NASA has released a beautiful ultraviolet image taken by the Hubble Space Telescope of the gas giant Jupiter.
This Hubble image shows Jupiter in ultraviolet...
A giant collision between the ancient protoplanet Theia and the proto-Earth about 4.5 billion years ago may have formed Earth’s Moon as well as two continent-sized...
Using data from the Jovian InfraRed Auroral Mapper (JIRAM) aboard NASA’s Juno spacecraft, planetary scientists have detected hydrated sodium chloride,...
While the ultraviolet aurora of Uranus has been observed since 1986, no confirmation of the infrared aurora had been observed until now.
An artistic representation...
Venus is the least understood of the terrestrial planets. Despite broad similarities to the Earth in mass and size, Venus has no evidence of plate tectonics...
Mars’ liquid iron alloy core is surrounded by a layer of fully molten silicate (magma) about 150 km thick, according to a pair of papers published in...
Ancient river deposits exist across Mars and can be identified in satellite data by erosional landforms called fluvial ridges. Fluvial ridges take the...
By analyzing tiny lunar zircon crystals gathered by Apollo 17 astronauts in 1972, planetary scientists recalculated the age of the Moon. Although previous...
