Hubble Finds New Neptune Moon

NASA’s Hubble Space Telescope has discovered a new moon orbiting the distant blue-green planet Neptune, the 14th known to be circling the giant planet.

The moon, designated S/2004 N 1, is estimated to be no more than 12 miles across, making it the smallest known moon in the Neptunian system. It is so small and dim that it is roughly 100 million times fainter than the faintest star that can be seen with the naked eye. It even escaped detection by NASA’s Voyager 2 spacecraft, which flew past Neptune in 1989 and surveyed the planet’s system of moons and rings.

The method concerned following the movement of a white dot that seems over and once more in additional than a hundred and fifty repository Neptune pictures taken by Edwin Powell Hubble from 2004 to 2009.

On a whim, Showalter looked way on the far side the ring segments and detected the white dot regarding sixty five,400 miles from Neptune, placed between the orbits of the Neptunian moons Larissa and Proteus. The dot is S/2004 N one. Showalter planned a circular orbit for the moon, that completes one revolution around Neptune each twenty three hours.

The Edwin Powell Hubble area Telescope may be a cooperative project between {nasa|National Aeronautics and area Administration|NASA|independent agency} and therefore the European Space Agency. NASA’s Goddard area Flight Center in belt, Md., manages the telescope. The area Telescope Science Institute (STScI) in metropolis, Md., conducts Edwin Powell Hubble science operations. STScI is operated by the Association of Universities for analysis in physical science Iraqi National Congress., in Washington.
