Lee Rannals for redOrbit.com - Your Universe Online According to NASA, the Hubble Space Telescope has revealed that Neptune has been hiding another moon, bringing the total count of moons orbiting the planet to 14. The new moon, named S/2004 N 1, is no more than 12 miles across, making it the smallest known moon in the Neptunian system. NASA said this moon is so small that it is about 100 million times fainter than the faintest star that can be seen with the naked eye. The moon is so...

John P. Millis, PhD for redOrbit.com - Your Universe Online Previously known simply as P4 and P5, the two smallest moons of the dwarf planet Pluto have officially been given new names. Discovered in 2011 and 2012 respectively, these two tiny bodies were found only after deep exposures using the Hubble Space Telescope. In order to choose new names for the icy bodies, an Internet poll was conducted in February of 2012. More than 500,000 votes were cast, half of which originated outside of...

IAU Speaks Out Against Planet Naming Site Uwingu

Lee Rannals for redOrbit.com — Your Universe Online A few months ago, a new space website opened up its doors for the public to start selecting the names of other planets. Now, the International Astronomical Union (IAU) has stepped up and pointed out this isn't exactly the protocol for the scientific process of naming cosmic bodies. Over 800 planets have been detected outside the Solar System so far, and thousands more are still waiting to be confirmed. Recently, the website...

Astronomers Make First Direct Observation Of A Forming Planet

[WATCH VIDEO: Flying Through The HD 100546 System] Lee Rannals for redOrbit.com — Your Universe Online Astronomers, for the first time, may have made a direct observation of a planet forming inside a thick disc of gas and dust. An international team led by Sascha Quanz, of the Swiss Federal Institute of Technology (ETH Zurich), used the European Space Observatory's (ESO) Very Large Telescope (VLT). Their discovery could help improve scientists' knowledge of how planets form and...

Lee Rannals for redOrbit.com - Your Universe Online - Video 1 | Video 2 | Video 3 Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that the outer region of a dusty disc encircling a brown dwarf contains solid grains like those found in denser discs of newborn stars. The find challenges theories of how rock, Earth-scale planets form, suggesting the planets may be more common in the Universe than expected. Scientists believe rocky planets form...

Astronomers Discover Comets Scattered Throughout Planetary Systems
2012-11-27 14:21:31

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have discovered vast comet belts that are surrounding two nearby planetary systems using the European Space Agency's (ESA) Herschel space observatory. Scientists found that that nearby planetary systems, GJ 581 and 61 Vir, have been found to host vast amounts of cometary debris. The ESA observatory detected the signatures of cold dust in quantities that mean these systems must have at least 10 times more...

Atmosphere Lacking On Dwarf Planet Makemake

[ Watch the Video: The Occultation of Dwarf Planet Makemake ] Lee Rannals for redOrbit.com - Your Universe Online New observations using three telescopes at the European Space Observatory's (ESO) Chile location have shown that the dwarf planet Makemake does not have much of an atmosphere after all. Astronomers originally predicted that the planet had an atmosphere like Pluto, but the new observations published in the journal Nature show that it actually doesn't. The planet is...

Preparing New Horizons: Obstacle Operations Planned Ahead Of Pluto Contact
2012-10-16 16:17:54

Lee Rannals for redOrbit.com — Your Universe Online NASA's New Horizons spacecraft is nearly seven years into its 9.5-year journey across the solar system to explore Pluto and its moons, but that journey is still far from over. As the spacecraft travels through space, its team has become aware of the possibility that dangerous debris may be orbiting in the Pluto system. "We've found more and more moons orbiting near Pluto -- the count is now up to five," Dr. Alan Stern,...

Uranus' moon Titania -- Titania is the largest moon of Uranus. Titania was discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus, Oberon, Titania, Ariel and Umbriel, were given by John Herschel, the son of William.

Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence. Early in their development most brown dwarf stars do have lithium fusion in their cores, and a lack of lithium is a test for low-mass objects that are suspected of being brown dwarfs. Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...
