California, October 1, 2017 : Pluto’s surface consists of sharp blades of ice that shoot to the height of skyscrapers in Dubai. And scientists now might just be able to tell precisely how these dramatic structures arose.

The revelations of ice on Pluto first altered our understandings in July 2015 when NASA’s New Horizons mission flew past the dwarf planet and sent images of astounding terrains back to earth. Among its numerous discoveries were pictures of strange formations, resembling giant blades of ice, whose origin could not be traced.

Now scientists have come up with a scientific explanation for this ‘knife-like landscape’.

According to data obtained by New Horizons, these structures are made almost entirely of methane ice. While the cause of these peaks is still a mystery, scientists contend that they are likely to arise following a specific kind of disintegration that wore away their surfaces, leaving dramatic peaks and sharp partitions on the planet.

These land edges can be found at the extreme heights on Pluto’s surface, close to its equator and soar as high as the New York skyscrapers. Scientists identify these high cutting blades as a complex feature of the planet’s atmosphere and topographical history.

According to Jeffrey Moore, a research scientist associated with the New Horizons’ mission, presently at NASA’S Ames Research Center in California, the knife-like terrain began with methane solidifying out of the climate at extreme elevations on Pluto. This can be understood to happen in the same manner as frost freezing on Earth, the only difference being in the scale of the two.

These structures can also be found on Earth and are called penitentes. However, here they extend only up to a couple of meters in height in the high-altitude snowfields along the planet’s equator. Researchers believe slight inconsistencies can transform them into dramatic spikes of snow as sunlight sublimates a few sections faster than others and prompting longer and spikier structures.

The discovery of penitentes on Pluto highlights its complex surface and air temperature changes.

The new finding is set to appear in an upcoming issue of the journal Icarus.

Another Space Telescope Shuts Down: NASA

Launched by space shuttles in the 1990s, Hubble and Chandra are part of NASA's Great Observatories series.

Second Space Telescope Shuts Down, NASA Says Pixabay

Another NASA space telescope has shut down and halted science observations.

Less than a week after the Hubble Space Telescope went offline, the Chandra X-ray Observatory did the same thing. NASA said Friday that Chandra automatically went into so-called safe mode Wednesday, possibly because of a gyroscope problem.

Hubble went into hibernation last Friday because of a gyroscope failure.

Both orbiting observatories are old and in well-extended missions: Hubble is 28, while Chandra is 19. Flight controllers are working to resume operations with both.

NASA said it’s coincidental both went “asleep” within a week of one another. An astronomer who works on Chandra, Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, tweeted Friday that “Chandra decided that if Hubble could have a little vacation, it wanted one, too.”

Launched by space shuttles in the 1990s, Hubble and Chandra are part of NASA’s Great Observatories series. The others are the Compton Gamma Ray Observatory, which was also launched in the 1990s but eventually failed and was destroyed, and the Spitzer Space Telescope, launched in 2003 and still working. Each was intended to observe the cosmos in different wavelengths. (VOA)
