Using ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), an international team of astronomers track Neptune’s atmospheric temperatures over a 17-year…
Neptune Is Cooler Than We Thought New research led by space scientists at the University of Leicester has revealed how temperatures in Neptune’s atmosphere have…
Probing the structures and properties of superionic ice. A layer of “hot,” electrically conductive ice could be responsible for generating the magnetic fields of ice…
Mushballs – giant, slushy hailstones made from a mixture of ammonia and water – may be responsible for an atmospheric anomaly at Neptune and Uranus…
It’s been 30 years since NASA last visited Venus, with the Magellan orbiter in 1990. Now, two new missions have been selected to explore the deadly atmosphere, crushing…
While scientists have amassed considerable knowledge of the rocky planets in our solar system, like Earth and Mars, much less is known about the icy…
Uranus and Neptune both have a completely skewed magnetic field, perhaps due to the planets’ special inner structures. But new experiments by ETH Zurich researchers…
This video is a full-globe map of the distant planet Neptune, created from Hubble Space Telescope data taken January 7-8, 2020. The movie reveals Neptune’s…
One of four concepts being considered for a Discovery Program mission, Trident would investigate one of the solar system’s most unusual worlds. When NASA’s Voyager…
Even by the wild standards of the outer solar system, the strange orbits that carry Neptune’s two innermost moons are unprecedented, according to newly published…
In 1989, NASA’s Voyager 2 zipped past Neptune—its final planetary target before speeding to the outer limits of the solar system. It was the first…
Astronomers using the NASA/ESA Hubble Space Telescope, along with older data from the Voyager 2 probe, have revealed more about the origin of Neptune’s smallest…
Since Pluto’s demotion from fully-fledged planet to dwarf planet, Neptune holds the title of outermost planet in the Solar System. This new image of the…
ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test…
Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm – once big enough to stretch across…
NASA has released the first study of potential future missions to the mysterious “ice giant” planets Uranus and Neptune. The Ice Giant Mission Study is…
Seventy days worth of solar system observations from NASA’s Kepler spacecraft, taken during its reinvented “K2” mission, are highlighted in this sped-up movie. The planet…
This newly released image of Neptune and its large moon Triton was captured by NASA’s New Horizons Spacecraft as it continues on its voyager towards…
