A look at Neptune, a potential gateway to the stars... Visit our sponsor, Brilliant: The Icy Giants, Neptune and Uranus, are often overlooked for as candidates for colonizing our solar system. Even when noted, the focus tends to be on their larger moons like Triton. Today we will challenge that notion by looking at way we might place a colony on the planet itself, and how Orbital Rings and Chandelier Cities might let us colonize any gas giant. We will also look at how helium-3, a core ingredient of aneutronic fusion abundant on Neptune, might serve as the fuel of future starships, and the physics behind some other starship drives future science might give us access to, such as laser propulsion.

JHU Applied Physics Laboratory 45.6K subscribers Neptune Odyssey The Johns Hopkins University is a planetary mission concept study conducted by the Johns Hopkins Applied Physics Laboratory under contract from NASA to support the 2023-2032 Planetary Science and Astrobiology Decadal Survey. The mission concept involves a spacecraft entering into orbit around the ice giant planet Neptune, deploying an atmospheric entry probe into Neptune's atmosphere. The orbiter would study Neptune, its rings, small satellites and space environment, as well as the captured dwarf planet, moon and likely ocean world, Triton.
Like a long-married couple accustomed to each other’s kitchen habits, two of Neptune’s moons are masters at sharing space without colliding. And though both situations may appear odd to an observer, there’s a certain dance-like quality to them both.

The moons of Uranus and Neptune are some of the most fascinating and least known worlds in the Solar System. Here's what we know about them. Me on Facebook: Me on Twitter:
Neptune is about 30 times farther from the Sun than our Earth. As the last of the major planets, it orbits the Sun almost in complete darkness. Due to the lack of light, Neptune can only be seen from Earth with very good telescopes. The latest telescope now provided brand new views of this normally luminous blue planet. In this photo from the James Webb Telescope, Neptune shines almost as brightly as a star. But where did the glow suddenly come from, and what makes this planet so unique? Let's take a look at the latest discoveries and findings about the enigmatic ice giant Neptune.
NASA's Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken on Aug. 20, 1989, at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach on Aug. 25. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called "Scooter" and the little dark spot are visible. These clouds were seen to persist for as long as Voyager's cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen. In the summer of 2015, another NASA mission to the farthest zone of the solar system, New Horizons, will make a historic first close-up study of Pluto. Although a fast flyby, New Horizons' Pluto encounter on July 14, 2015, will not be a replay of Voyager but more of a sequel and a reboot, with a new and more technologically advanced spacecraft and, more importantly, a new cast of characters. Those characters are Pluto and its family of five known moons, all of which will be seen up close for the first time next summer(2015) Image Credit: NASA
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 images of the planet Neptune, star clusters and other objects. The pioneering MUSE instrument in Narrow-Field Mode, working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope. The combination of exquisite image sharpness and the spectroscopic capabilities of MUSE will enable astronomers to study the properties of astronomical objects in much greater detail than was possible before. This ESOcast gives a taste of these remarkable results. The video is available in 4K UHD. The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces.

Although new missions to Neptune have been proposed, none are likely to arrive for many decades.
So for now, the only way to better understand how the planet works is through computer simulations.
In a new example of interdisciplinary research at Imperial College London, the space and atmospheric
physics group and the plasma physics group have been working together to address this challenge.

Storms on Neptune seem to follow a pattern of forming, strengthening and then dissipating over the course of about two Earth years. But a Neptunian storm spotted in the planet’s atmosphere over two years ago has done something quite different: it has reversed course and is still going strong. The storm, which is wider than the Atlantic Ocean, originated in the planet’s northern hemisphere and seen with the Hubble Space Telescope in 2018. Observations a year later showed that it began drifting southward toward the equator, where previous similar whirling storms went to die. But recent observations with Hubble spotted the vortex doubling back to the north in August of 2020.

Welcome to the exciting world of space exploration! In this video, we're excited to announce that the first REAL images have been taken from the surface of Triton, the largest moon of Neptune! This groundbreaking documentary film follows a team of scientists as they undertake the complex and dangerous journey to capture these stunning images. Not only are these images the first taken from Triton's surface, but they also reveal new information about the mysterious giant planet Jupiter and its moon, moon of moon, Triton!
Paul Schenk of the Lunar and Planetary Institute used data from NASA's Voyager 2 spacecraft,
which flew by Neptune and its big moon Triton on Aug. 25, 1989, to create this best-ever global color map of the moon.
"In the intervening quarter century and its many discoveries, I think we have tended to forget how strange and exotic Triton really is!"
Schenk wrote in a blog post Thursday (Aug. 21, 2014).

Neptune's largest moon Triton boasts an uncommon icy mixture of carbon monoxide and nitrogen, which could help astronomers better understand the conditions of other distant alien worlds. Using the Gemini Observatory in Chile and the high-resolution spectrograph called IGRINS (Immersion Grating Infrared Spectrometer), a visiting instrument for Gemini, astronomers detected a distinct infrared signature on Triton, revealing a mixture of carbon monoxide and nitrogen frozen as solid ice. This finding helps explain seasonal atmospheric changes on Triton and how material is transported across the moon's surface via geysers, according to a statement. Prior to detecting this unique signature on Triton, researchers first identified the specific wavelength of infrared light absorbed by an ice mixture of carbon monoxide and nitrogen molecules in the lab. "While the icy spectral fingerprint we uncovered was entirely reasonable, especially as this combination of ices can be created in the lab, pinpointing this specific wavelength of infrared light on another world is unprecedented," Stephen Tegler, lead author of the study from Northern Arizona University's Astrophysical Materials Laboratory, said in the statement. The icy mixture detected on Triton could help explain the moon's iconic geysers, which are the dark, windblown streaks first observed by NASA's Voyager 2 spacecraft in the moon's south polar region. These distinct streaks are believed to be erupted material from an internal ocean, or an icy mixture that migrates around the surface in response to changing seasonal patterns of sunlight, according to the statement. "Despite Triton's distance from the sun and the cold temperatures, the weak sunlight is enough to drive strong seasonal changes on Triton's surface and atmosphere," Henry Roe, deputy director of Gemini and a member of the research team, said in the statement. "This work demonstrates the power of combining laboratory studies with telescope observations to understand complex planetary processes in alien environments so different from what we encounter every day here on Earth." In fact, NASA's New Horizons spacecraft found that carbon monoxide and nitrogen ices coexist on Pluto. However, the recent findings are the first evidence of these ices mixing, according to the statement. Therefore, the study, which will be published in The Astronomical Journal, sheds light on the possible composition of ices and seasonal variations in the atmosphere on other distant worlds beyond Neptune.
Subscribe to Naked Science – Welcome to Triton, one of Neptune’s moons, super-chilled and covered in frozen nitrogen snow. It would be big enough for us to live on, the question is, could we? Triton is the largest natural satellite of the planet Neptune, and the first Neptunian moon to be discovered, by English astronomer William Lassell in 1846. It is the only large moon in the Solar System with a retrograde orbit, an orbit in the opposite direction to its planet's rotation. Clip taken from the Naked Science documentary “Deadliest Planets”.
Talk about recycling! Twenty-five years after Voyager 2 zinged past Neptune�s moon Triton, scientists have put together a new map of the icy moon�s surface using the old data. The information has special relevance right now because the New Horizons spacecraft is approaching Pluto fast, getting to the dwarf planet in less than a year. And it�s quite possible that Pluto and Triton will look similar.
Published on Aug 21, 2014 The Voyager 2 spacecraft flew by Triton, a moon of Neptune, on August 25, 1989. Paul Schenk,
a scientist at the Lunar and Planetary Institute in Houston, used Voyager data to construct this video recreating that exciting encounter.
Published on May 6, 2016 In the summer of 1989 Earthlings got their first view of Neptune and its formidable moon Triton. Fast forward 25 years and scientists are working on technologies to not only visit this icy moon but ‘hop' around on its surface too. NASA 360 joins Geoffrey A. Landis and Steven Oleson, both of NASA Glenn Research Center, as they discuss their concept for a hopper vehicle to explore Triton.

The Lesser Worlds - Episode #2 At the most distant recesses of our Solar System lay the ice giant planets, Uranus and Neptune. We have only managed to visit these worlds once, and as such we know considerably less about the moons that orbit them. However, one moon stands out from the rest - Triton. Today, we will examine its unique features, and also relive the story of how this Kuiper Belt object came to be Neptune's largest satellite. FOLLOW MY NEW TWITTER!

Is it time to head back to Neptune and its moon Triton? It might be. After all, we have some unfinished business there. It’s been 30 years since NASA’s Voyager 2 spacecraft flew past the gas giant and its largest moon, and that flyby posed more questions than it answered. Maybe we’ll get some answers in 2038, when the positions of Jupiter, Neptune, and Triton will be just right for a mission. NASA is deliberating over the next mission in its Discovery Program, narrowing it down to four possibilities: a mission to study Venus’ atmosphere, one to observe volcanic activity on Jupiter’s moon Io, one to map Venus’ surface and study its geology, and one to explore Neptune’s moon Triton.

Triton is by far the largest of Neptune’s moons. It’s in a counter-rotation with neptune, and is most likely a captured Kuiper Belt Object, rather than an in-situ moon. Neptune’s outer moon Neried is on a highly elliptical orbit and is not shown. Image Credit: NASA / ESA / A. Feild, STScI
The surface of Triton is very rugged, scarred by rising blobs of ice, faults and volcanic pits and lava flows composed of water and other ices. The surface is also extremely young and sparsely cratered, and could be geologically active today. This Voyager image shows the moon’s “cantaloupe terrain.” This scene is on the order of 150 meters (500 feet) across. Vertical relief has been exaggerated by a factor of 25 to aid interpretation.

Three grainy images of Triton’s surface from Voyager 2. This is a time sequence of image taken 45 minutes apart, from top to bottom. They show a dark geyser-like plume of material reaching a height of 8 km (5 mi) above the surface. The cloud of material drifts downward to the right for about 150 km (100 miles) and appears to get denser in each image. Image Credit: NASA/JPL
This Voyager 2 images shows a close-up of a prominent chain of volcanic features surrounded by smooth volcanic plains formed by lavas or ash deposits of water or other ices, such as methane or ammonia. The smaller pits and domes are typically 10 kilometers (6 miles) across and have relief of no more than a few hundred meters (several hundred feet). The large depressions at the far left and right of the chain are 50 to 80 kilometers (31 to 50 miles) across.

Neptune's rotational axis (28.3°) is a little more tilted than Earth's (23.5°) and, because it has no solid surface, its equatorial atmosphere spins more slowly (18 hrs.) than its magnetic field (16 hrs.). Researchers at London's Imperial College have combined Voyager's dataset with plasma and atmosphere observations to accurately model Neptune’s magnetosphere for the first time. -- Full Story: Credit: Imperial College, London / NASA / Space.com

Earlier this year, NASA announced 4 new Discovery-class missions that they were considering. These are low-cost, rapidly-built missions that will help scientists understand some mystery in astronomy and planetary science. One of these missions is called Trident, and it’s going to be targeting the Planet Neptune. And more specifically, it’s going to be providing close up pictures of its largest moon Triton.

VIDEOS ON NEPTUNE
What is the Mysterious Extraterrestrial World of Neptune like ? | Space Documentary
🌍 Neptune is known as the eighth most distant planet from the Sun. It lies more than 4 billion miles from Earth, making it too far away to be seen by the naked eye. On September 23, 1846, Neptune was the first planet to be discovered through mathematical calculations. It was the second planet after Uranus to be revealed with a telescope, but the first planet discovered by astronomers who were specifically looking for it. Because of its blue color, Neptune was named after the god of the sea in Roman mythology. The story of the discovery of this mysterious blue giant on the outskirts of the solar system is quite curious and unusual. It was a triumph for Newtonian physics, because it proved that the motion of planets is entirely subject to the laws of gravity. Neptune has a composition close to Uranus, and both planets are placed in a distinct category of "ice giants". Neptune has a bright blue color with a particular azure tint. Externally, it looks very similar to Uranus, these two planets can even be confused. However, the color of Neptune is more saturated and bright. Neptune is the smallest of the gas giants. Also called the planet of storms, Neptune is the seat of the strongest winds in the solar system. 🔥 As a reminder, videos are published on SUNDAYS at 6:00 PM. ------------------------- 💥 The Extraterrestrial World of the Planet Neptune: - Neptune is the eighth most distant planet in the solar system. It is also the fourth largest planet in diameter and the third largest in mass. In fact, Neptune's mass is 17 times greater than Earth's while its diameter is only 4 times greater than our planet. Despite its title as the 4th largest planet in the solar system, we could easily fit 58 Earth inside Neptune. Thus, the average density of Neptune is only 1.6 g / cm3, that is to say about one third of that of the Earth, or about one and a half times more than that of water. The low densities are characteristic of the four giant planets: Jupiter, Saturn, Uranus and Neptune. Among these four, the first two are the least dense because they are mainly made of gas. The densest are Uranus and Neptune because they are mainly made of ice. With Uranus, Neptune belongs to a subclass of gas giants, called "ice giants" because of their smaller size and their composition made mainly of volatile elements such as methane, ammonia and water, rather than hydrogen and helium. The average distance between Neptune and the Sun is 4.5 billion km, which is about 30 times the average distance between the Sun and the Earth, and it takes almost 165 years for Neptune to make one complete revolution around our star. The distance between Neptune and Earth is between 4.3 and 4.6 billion km. On July 12, 2011, Neptune made its first complete orbit since the discovery of the planet in 1846. Seen from our planet, Neptune could thus be observed differently since the day of its discovery, because the period of revolution of the Earth around the Sun, which is 365 days, is not a multiple of the period of revolution of Neptune. The axial tilt of Neptune is 28.3°, which is similar to the axial tilt of the Earth and Mars. Therefore, the planet experiences similar seasonal changes. However, due to Neptune's long orbital period, the seasons last about forty years each. Neptune's sidereal rotation period is about 16 hours and 7 minutes. Due to an axial tilt similar to that of the Earth, changes in the sidereal rotation period during its long year are not significant. Among all the planets of the solar system, this type of rotation is the most pronounced in Neptune. This leads to a strong latitudinal wind shift.
