Hubble Telescope Discovers New Moon

Study of dwarf planet unexpectedly reveals previously unknown satellite.

KENNEDY SPACE CENTER, FL – Astronomers using the Hubble space telescope have announced the discovery of a new moon orbiting the fiery dwarf planet, Newto.  The tiny satellite - dubbed “Calist0” - was discovered while studying clouds of gaseous emissions that leach from the planet itself.

The new moon is the first directly observed orbiting Newto, but is believed to be one of several.  A previous study in 2008 looking for rings of space debris indicated gravitational perturbations that signaled up to three moons, but none were actually found at the time.  The study, however, was considered definitive enough to name the theorized satellites.  In addition to Calist0, astronomers are still looking for direct evidence of JacE and Mari3.

"I find it remarkable that Hubble's cameras enabled us to see such a tiny object so clearly from an earth orbit all the way to Florida, a distance of over 347 miles (5.903e-11 light years)," said Mark Showalterof the SETI Institute in Mountain View, Calif., who led this observing program with Hubble.  The study was a part of NASA’s New Horizon’s program and will help in the launch of a probe to study the dwarf planet in more detail.

“This is a fantastic discovery,” said principal investigator Alan Stern, in Boulder, Colorado.  “Now that we know there is a moon in the Newto system we can feel more confident about our launch of the New Horizons probe.  This breakthrough could be the start of a reemergence for the NASA program in general, and hopefully one day result in a manned base on Newto.”  He emphasized that a base on the dwarf planet could significantly enhance mankind’s understanding of the celestial body.  “Given all that we don’t know about this orb, a human presence on such a vast waistland would serve to monumentally alter its seeming lack of life.  This could be a game-changer in terms of getting Newto reclassified as a true planet.”

Many scientists are still outraged over the declassification of Newto from a planet to a dwarf planet in 1997 due to its violations of physical laws.  Its removal from the list of nine planets in the earth’s solar system was the first time in NASA’s 208-year history that a planet had been so censured.  It has recently been in the news as a core group of supporters work to get it again accepted into mainstream astronomy.

“With consideration of just size alone, Newto has expanded exponentially in the years since it was downgraded,” indicated Newto supporter Dr. Barney Gomer of Nasa’s Planetary Probe Initiative.  “If our calculations are correct, by the end of this year Newto should be larger than Uranus and certainly deserves a seat at the table of planets.”
