New Neptune Moon Found by Hubble Space Telescope

NASA this week revealed that a new moon has been spotted orbiting the furthest planet from the sun, Neptune. The moon, the 14th known to be orbiting Neptune, has been labeled S/2004 N 1. The small rock is the smallest of Neptune’s known moons at approximately 12 miles across. It is located around 65,400 miles from Neptune, between the orbits …

Hubble Telescope Spots a Blue Planet

Astronomers have been finding and cataloging exoplanets for years now, but NASA this week announced that the Hubble Space Telescope has helped determined the color of a planet orbiting a star 63 light-years from our solar system. The planet, HD 189733b, has been found to be blue in color. Astronomers determined this using Hubble’s imaging spectrograph, which was able to …

Three Planets Found in the Habitable Zone of Nearby Star

The European Southern Observatory (ESO) this week announced it has found six planets in the Gliese 667C system, and that three of those planets are located within the system’s habitable zone. The habitable zone of a system is the area around a star where liquid water can exist. With the presence of water also comes the possibility for life as …

Giant Planet Formation May Have Been Spotted

Astronomers have found what could be the first-ever sighting of a planet forming while still in the midst of a dust cloud surrounding a star. The object, which orbits the star HD 100546, is only 335 light-years from Earth and appears to be a gas giant. If the findings, published this week in Astrophysical Journal Letters, are confirmed, they could …

NASA’s Kepler Finds Extra-Solar Planets Smaller Than Earth

Over the past year, NASA’s Kepler mission has found hundreds of possible planets outside of our solar system, and even a few candidates for Earth-like planets. This week, astronomers revealed that a new system has been found that contains planets smaller than Earth. The new data has been presented in a paper published recently in the journal Nature. The planets …

Earth-Sized Planets May be Close by, Shows Study

Astronomers this week published a new study that estimates six percent of red dwarf stars may have Earth-sized planets orbiting within their “habitable zone” – the area around a star in which liquid water can exist on the surface of an orbiting body. Since many stars close to our solar system are red dwarfs, astronomers say an Earth-like planet could …

Comet-Like Ionosphere Seen on Venus

New observations of Venus have shown that the planet’s ionosphere on its night side resembles a comet’s tail. The observations were made by the European Space Agency’s (ESA) Venus Express satellite. The ionosphere is the region of electrically charged gas high in a planet’s atmosphere. The shape and density of an ionosphere are determined, in part, by the internal magnetic …

Rogue Planet Orbit Spotted by NASA’s Hubble

New images of the Fomalhaut star system could show evidence of a “titanic planetary disruption.” Astronomers have found that the debris belt in the system is wider than was thought, and that a “rogue” planet has a precarious orbit that takes it straight through the dust ring. The debris belt spans a huge section of space from 14 to around …

461 New Planet Candidates Discovered by NASA’s Kepler, Including Four Earth-Like Ones

Astronomers last week announced that they estimate there to be 100 billion planets throughout the Milky Way Galaxy. This week, Astronomers announced 461 new candidates for extra-solar planets have been discovered. NASA‘s Kepler mission has been discovering exoplanets for years now, and the number of confirmed exoplanets is currently 105. As astronomers dig more deeply into Kepler data, smaller planet …

100 Billion Planets Populate the Milky Way Galaxy, Say Astronomers

For years now, NASA‘s Kepler mission has been confirming the existence of planets outside our solar system. Now, a new review of Kepler data suggests that there are billions upon billions of planets just in the Milky Way galaxy. “There are at least 100 billion planets in the galaxy, just our galaxy,” said John Johnson, assistant professor of planetary astronomy …

Giant Planet Formation Revealed in New Observations

Astronomers have spotted a system that could reveal a key stage in the formation of giant planets. For the first time, images of vast gas streams flowing across a gap in the accretion disc of a young star have been seen. The new research, published today in the journal Nature, shows that the gas streams found around a star named …

Close Star Could Have up to Five Planets

A new study by an international team of scientists has discovered that the star Tau Ceti may have five planets orbiting it. Tau Ceti is the 20th closest star to the sun, and the nearest star to have sun-like properties. The star has the same spectral classification as the sun, with a mass 78% that of the sun’s. It lies …
