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...
In a paper published in the Proceedings of the Royal Society A: Mathematical Physical and Engineering Sciences, researchers at the University of Cambridge...
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...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
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...
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...
Geoscientists from Durham University and elsewhere have discovered a landscape that appears to have been formed by rivers at least 14 million years ago...
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...
The newly-discovered intense (140 m/s) jet is confined to ±3° of Jupiter’s equator, is approximately 4,800 km wide, and is located in the gas giant’s...
