He maintained the Bill would bulldoze the rights of the indigenous people of the state and the North Eastern Region as a whole if lakhs of migrants from Bangladesh, Afghanistan and Pakistan are granted citizenship rights. He threatened that the organization will resort to violence if the Central government goes ahead with the Bill while asserting that the Central government would be responsible if such chaos erupts. Prior to the burning of the effigy, KSU president, Lambokstarwell Marngar said, “Though the state government has opposed the Bill, it is yet to take a resolution and send it to the Central government to register its opposition to the Bill.” Lissauer and Imke de Pater, 22 October 2019, Icarus.SHILLONG: As a mark of protest against the Citizenship (Amendment), Bill 2016, the Khasi Students’ Union (KSU) and North East Students’ Organisation (NESO) burnt the effigy of the Bill at Civil Hospital junction, near the statue of Khasi-Jaintia freedom fighter, Kiang Nangbah on Monday. Reference: “Orbits and resonances of the regular moons of Neptune” by Marina Brozović, Mark R. They maintain the peace by never getting too close.” “Naiad and Thalassa have probably been locked together in this configuration for a very long time, because it makes their orbits more stable. “We are always excited to find these co-dependencies between moons,” said Mark Showalter, a planetary astronomer at the SETI Institute in Mountain View, California, and a co-author of the new paper. Researchers used the observations to compute their mass and, thus, their densities - which were close to that of water ice. The work also provides the first hint about the internal composition of Neptune’s inner moons. “Only later, after its orbital tilt was established, could Naiad settle into this unusual resonance with Thalassa.”īrozovic and her colleagues discovered the unusual orbital pattern using analysis of observations by NASA’s Hubble Space Telescope. “We suspect that Naiad was kicked into its tilted orbit by an earlier interaction with one of Neptune’s other inner moons,” Brozovic said. So how did they end up together - but apart? It’s thought that the original satellite system was disrupted when Neptune captured its giant moon, Triton, and that these inner moons and rings formed from the leftover debris. There are many different types of ‘dances’ that planets, moons, and asteroids can follow, but this one has never been seen before.” - Marina Brozovic, NASA’s Jet Propulsion Laboratory “We refer to this repeating pattern as a resonance. They are two of Neptune’s seven inner moons, part of a closely packed system that is interwoven with faint rings. Naiad and Thalassa are small and shaped like Tic Tacs, spanning only about 60 miles (100 kilometers) in length. Neso, the farthest-flung of them, orbits in a wildly elliptical loop that carries it nearly 46 million miles (74 million kilometers) away from the planet and takes 27 years to complete. Some orbit in the opposite direction their planets rotate others swap orbits with each other as if to avoid collision. Some of those moons formed alongside their planets and never went anywhere others were captured later, then locked into orbits dictated by their planets. “There are many different types of ‘dances’ that planets, moons, and asteroids can follow, but this one has never been seen before.”įar from the pull of the Sun, the giant planets of the outer solar system are the dominant sources of gravity, and collectively, they boast dozens upon dozens of moons. “We refer to this repeating pattern as a resonance,” said Marina Brozovic, an expert in solar system dynamics at NASA’s Jet Propulsion Laboratory in Pasadena, California, and the lead author of the new paper, which was published November 13 in the journal Icarus. This up, up, down, down pattern repeats every time Naiad gains four laps on Thalassa.Īlthough the dance may appear odd, it keeps the orbits stable, researchers said. An observer sitting on Thalassa would see Naiad in an orbit that varies wildly in a zigzag pattern, passing by twice from above and then twice from below. In this perpetual choreography, Naiad swirls around the ice giant every seven hours, while Thalassa, on the outside track, takes seven and a half hours.
