The Hubble Space Telescope has taken anniversary pictures of Neptune, revealing high-altitude clouds in the northern and southern hemispheres composed of methane ice crystals. The images also show that cloud activity is shifting to the northern hemisphere, with seasons lasting about 40 years.
A University of Arizona planetary scientist has determined Neptune's rotation with high accuracy by tracking atmospheric features in its atmosphere. The discovery improves upon previous measurements and provides a better understanding of the planet's fundamental properties.
Researchers found binary systems in the Kuiper Belt would be destroyed by Neptune's interaction, contradicting previous assumptions. The study suggests the region formed near its present location and remained undisturbed over the age of the solar system.
Asteroid 2008 LC18 is found in the L5 stability region of Neptune, with an estimated diameter of 100 kilometers. The discovery suggests a population of similar asteroids at L5, outnumbering those in the main asteroid belt.
Researchers plan to use FAIR facility in Germany to expose water molecules to heavy ion beams, generating extreme pressure conditions similar to Neptune's core. This will allow scientists to observe 'superionic' state of water, a hybrid phase with oxygen lattice and hydrogen liquid.
Researchers believe that Galileo's notebooks from 1613 may reveal evidence of his discovery of a new planet, which is now known as Neptune. The planet was observed by Galileo as a faint star near Jupiter and moved relative to an actual nearby star.
The University of Victoria-led NEPTUNE Canada observatory will receive a significant boost in funding, allowing for expansion of its scope and scientific impact. The additional $20 million will enable more comprehensive studies on ocean-climate interactions, fisheries, gas hydrate deposits, and seafloor ecology.
Astronomers have found four stable groups of asteroids around the Sun: Kuiper Belt, Jupiter Trojans, main asteroid belt, and now Neptune Trojans. The new discoveries suggest a large population of high-inclination Neptune Trojans, which may have formed after giant planets settled into their orbits.
A new model for the capture of planetary satellites involving a three-body gravitational encounter between a binary and a planet suggests that Triton was originally part of a binary pair orbiting the Sun. This mechanism introduces a new pathway for satellite capture by planets, which may be relevant to other objects in the solar system.
A nuclear-powered space mission to Neptune, expected to launch between 2016 and 2018, aims to gather data on the planet's atmosphere and its largest moon Triton. The mission will employ electrical and optical sensors to study Neptune's atmospheric elemental ratios, gravity, and magnetic fields.
Astronomers used Hubble to search for faint Kuiper Belt objects, finding only three small objects in a 15-day period. The discovery suggests that smaller planetesimals may have been shattered into dust by colliding with each other, affecting the number of comets near Earth.
Researchers from the University of Notre Dame and NASA's Goddard Space Flight Center used an infrared spectrometer to determine the carbon monoxide/water ratio in comet Hale-Bopp. The findings suggest that the comet formed 4 billion years ago, providing clues about its history and composition.
Scientists have captured the most insightful images to date of Neptune's wildest weather, including monster storms and equatorial winds of 900 miles per hour. The new observations revealed a
