    JANUARY 17, 2015 Ted Cruz and the Ice Giants Senator Ted Cruz now oversees NASA, and that’s a very good thing.By Josh Gelernter Neptune, photographed by Voyager 2 in 1989. (NASA)With the GOP in charge of the Senate, Ted Cruz has taken charge of the Science, Space, and Competitiveness subcommittee. Which means Ted Cruz now oversees NASA. On Wednesday, Cruz issued a statement saying that “Our space program marks the frontier of future technologies for defense, communications, transportation and more, and our mindset should be focused on NASA’s primary mission: exploring space and developing the wealth of new technologies that...
  • What is Pluto?

    01/31/2022 7:41:35 PM PST · by CondoleezzaProtege · 39 replies
    Pluto is a dwarf planet. A dwarf planet travels around, or orbits, the sun just like other planets. But it is much smaller. Clyde Tombaugh discovered Pluto in 1930. He was an astronomer from the United States. An astronomer is a scientist who studies stars and other objects in space. Venetia Burney named Pluto that same year. She was an 11-year-old girl from England. Pluto is not very big. It is only half as wide as the United States. Pluto is smaller than Earth's moon. This dwarf planet takes 248 Earth years to go around the sun. If you lived...

    I have carried out a search for Planet 9 in the IRAS data. At the distance range proposed for Planet 9, the signature would be a 60 micron unidentified IRAS point source with an associated nearby source from the IRAS Reject File of sources which received only a single hours-confirmed (HCON) detection. The confirmed source should be detected on the first two HCON passes, but not on the third, while the single HCON should be detected only on the third HCON. I have examined the unidentified sources in three IRAS 60micron catalogues: some can be identified with 2MASS galaxies, Galactic...
  • Potential orbit of mysterious Planet Nine which may lurk on edge of our solar system has been plotted by scientists

    Scientists have debated the existence of Planet Nine since it was first introduced several years ago, but a new study has determined the orbit of the alleged celestial object. Caltech researchers Mike Brown and Konstantin Batygin have plotted the orbital path of the mystical planet, which has yet to be discovered. In a blog post, Brown detailed that the 'highest probability' of Planet Nine's location is near aphelion - the point at which it is furthest from the sun - around 60 degrees in Right Ascension, 'pretty close to the galactic plane.' If in fact Planet Nine were at the...

    Neptune's largest moon, Triton, was originally a member of a duo orbiting the Sun but was kidnapped during a close encounter with Neptune, a new model suggests. Triton is unique among large moons in that it orbits Neptune in a direction opposite to the planet's rotation, which long ago led scientists to speculate that the moon originally orbited the Sun. But until now, no convincing theory for how Triton paired with Neptune existed. Gravity might have pulled Triton away from its companion to make it an orbiting satellite of Neptune, researchers report in a new study published in the May...

    The planets of the outer Solar System are known for being strange, as are their many moons. This is especially true of Triton, Neptune’s largest moon. In addition to being the seventh-largest moon in the Solar System, it is also the only major moon that has a retrograde orbit – i.e. it revolves in the direction opposite to the planet’s rotation. This suggests that Triton did not form in orbit around Neptune, but is a cosmic visitor that passed by one day and decided to stay. ... Triton has a radius, density (2.061 g/cm3), temperature and chemical composition similar to...

    Neptune’s moons are ...all are named for gods of the sea, or for the children of Poseidon (which include Triton, Proteus, Depsina and Thalassa), minor Greek water dieties (Naiad and Nereid) or Nereids , the water nymphs in Greek mythology (Halimede, Galatea, Neso, Sao, Laomedeia and Psamathe). Neptune’s Regular Moons are those located closest to the planet and which follow circular prograde orbits that lie in the planet’s equatorial plane. They are, in order of distance from Neptune: Naiad , Thalassa , Despina, Galatea, Larissa , S/2004 N 1, and Proteus. All but the outer two are within Neptune-synchronous orbit......

    (NASA/JPL-Caltech) ================================================================================= Life isn't always easy for astrophysicists: just when they've figured out another aspect of the patterns of movement in our Solar System, along come two of the moons of Neptune to mess everything up. The two moons in question are Naiad and Thalassa, both around 100 kilometres or 62 miles wide, which race around their planet in what NASA researchers are calling a "dance of avoidance". Their strange orbit was first detected by NASA researchers in November 2019. Compared with Thalassa, Naiad's orbit is tilted by about five degrees – it spends half of its time above Thalassa...

    Uranus, far from Earth in the darker region of the Solar System's planetary reach, isn't alone. It's accompanied by a retinue of moons - 27, to be precise. Far and dim, these moons are difficult to study, but astronomers have made an accidental discovery while observing Uranus. According to infrared images of the five main moons of Uranus, their composition is closer to that of dwarf planets like Pluto and Haumea - compact, rocky objects with an icy crust - than the more fluffy composition of the smaller Uranian moons. Uranus orbits the Sun at an average distance around 20...

    A new paper describes how the researchers connected the moving dots to find the new TNOs, and also says this new approach could help look for the hypothetical Planet Nine and other undiscovered worlds. The Dark Energy Survey (DES) is designed to probe the origin of the accelerating universe and help uncover the nature of dark energy by measuring the 14-billion-year history of cosmic expansion with high precision. It studies galaxies and supernovas and precisely tracks their movements. This survey has been active since 2013, using the 4-meter Blanco Telescope located at Cerro Tololo Inter-American Observatory (CTIO) in Chile. The...

    Day by day, new images appear showing an ever clearer view of a world we inexplicably love. Call it a dwarf planet. Call it a planet. It’s the unknown, and we can’t help but be drawn there. Pluto made history when it was discovered in 1930. In 2015, it’s doing it all over again. Check out the new geology peeping into view.I’m reminded of the early explorers who shoved off in wooden ships in search of land across the water. After a long and often perilous journey, the mists would finally clear and the dark outline of land take form...

    A team of astronomers from NASA’s New Horizons mission has unveiled our best look yet at the far side of Pluto, which went unseen to the spacecraft during its historic July 2015 flyby of the dwarf planet. We have only seen one hemisphere of Pluto in high-resolution because the New Horizons flyby of Pluto lasted just hours, whereas the dwarf planet takes 6.4 Earth days to rotate. Thus as New Horizons flew past, one side of the world was illuminated by the Sun, but the other was shrouded in darkness. However, using images taken by the spacecraft while it was...

  • Moons that escape their planets are now called ‘ploonets’

    BGR ^ | 07/11/2109 | Miek Wehner
    The researchers suggest that this type of world may a result of large “hot Jupiter” exoplanets migrating toward their host star. Exoplanet surveys have detected several such planets, and it’s believed that they likely formed at a greater distance from their respective stars and then slowly crept inward. When that happens, it’s possible that the change in gravitational forces would prompt large moons to break free from their existing orbits and become standalone worlds of their own. Computer simulations showed that this could indeed happen, and in those cases, the researchers believe we should call them ploonets. Remarkably, our own...

    You might not care what Keith Richards or Jimmy Page think about Pluto's status as a dwarf planet, but when Queen guitarist Brian May speaks up about it, it's worth a listen. May, who received his doctorate in astrophysics in 2007, posted his Pluto thoughts on Instagram late Wednesday after hearing about how NASA administrator Jim Bridenstine still thinks of Pluto as a full-on planet. The International Astronomical Union (IAU) tightened up its definition of a planet in 2006 and demoted Pluto to dwarf-planet status, sparking an ongoing debate that just won't rest. May is on the pro-planet side of...

    hen NASA's New Horizons spacecraft flew past Pluto in 2015, researchers hoped that its data would help them unravel some of the dwarf planet's mysteries. Instead, the discoveries made during the close-up look at Pluto and its moon Charon revealed more questions that needed answering. One of the big revelations from the flyby was the discovery of an ocean beneath the icy shell encapsulating Pluto. The ice shell was thin in a spot near the equator that's about the size of Texas, known as Sputnik Planitia, which helped researchers notice Pluto's odd topography and suggest the ocean's existence. But this...

    Pluto and the Young Solar System by Dr. Lisle | Mar 8, 2019 | Astronomy, Origins | Pluto and the Young Solar System The outer solar system continues to confirm the biblical timescale. When the New Horizons spacecraft flew past the Pluto system in July 2015, its findings challenged secular expectations. In the standard old-universe model, Pluto formed about 4.5 billion years ago. Yet, New Horizons found evidence of a geologically “youthful” surface for both Pluto and its largest moon Charon. A recent study examining the sparse cratering on these worlds provides even additional evidence of their biblical age of...

    If you ever find yourself at a cocktail party of astrophysicists and don't know what to say, try this: "But what about the angular momentum?" No matter what the topic of conversation, you'll be guaranteed to sound erudite. Nearly every field of astronomy, from galaxy formation to star formation, has an "angular momentum problem." Nothing in the cosmos ever seems to spin or orbit at the rate it should. The moon is no exception. It is the flywheel to end all flywheels; if its orbital angular momentum were transferred to Earth's axial rotation, our planet would come close to spinning ...

    Act Two of the 12-year-old New Horizons mission to Pluto and the solar system’s icy Kuiper Belt is heating up, with less than a month to go before NASA’s piano-sized spacecraft makes history’s farthest-out close encounter with a celestial object. The New Year’s flyby of a mysterious Kuiper Belt object (or objects) known as Ultima Thule (UL-ti-ma THOO-lee) follows up on the mission’s first act, which hit a climax three years ago with a history-making flyby of Pluto. Launched in 2006, New Horizons was never meant to be a one-shot deal. Even before the Pluto flyby, mission managers used the...
