NASA Spots Weather Patterns on Brown Dwarf NASA Spots Weather Patterns on Brown Dwarf

Astronomers this week announced that they have produced a “weather map” for a brown dwarf that shows planet-sized clouds driven by wind. Brown dwarfs are objects at the edge of becoming a star. They lack the mass to begin hydrogen …

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

Solar Eruption Rang in the New Year, Shows NASA Video Solar Eruption Rang in the New Year, Shows NASA Video

While people across the world were celebrating or preparing to celebrate the arrival of the year 2013, the sun was putting on a New Year’s show of its own. On December 31, a massive solar eruption twisted up from the …

100 Billion Planets Populate the Milky Way Galaxy, Say Astronomers 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 …

Just in time for the holidays, NASA has released two new space photos filled with festive greens and reds. The photo seen above (a larger version of which can be seen here) was taken using NASA’s Spitzer Space Telescope. the …

Cassini to Track Venus Transit, Study Exoplanets Cassini to Track Venus Transit, Study Exoplanets

NASA announced today that it will begin using the Cassini probe’s visual and infrared mapping spectrometer (VIMS) for uses other than studying Saturn and its moons. On Friday, from its vantage point in orbit around Saturn, the VIMS will be …

NASA Releases a “Game” to Crowd-Source Cloud Classification NASA Releases a “Game” to Crowd-Source Cloud Classification

NASA this week has launched a “game” that allows anyone to identify galactic clouds in a series of photos. The game, called Clouds, is part of the Milky Way Project, which helps astronomers crowd source data sorting. It can be …

Globular Cluster Aging Revealed in New Study Globular Cluster Aging Revealed in New Study

Globular clusters are spherical groupings of stars tightly bound by gravity. While these objects are usually 12 to 13 billion years old, a new study has found that clusters can appear to be vastly different ages, depending on the behavior …

Radio-Emitting Jet Detected From Andromeda Black Hole Radio-Emitting Jet Detected From Andromeda Black Hole

Astronomers revealed this week that they have detected an intense radio emission from a black hole’s radio-emitting jet. The emission was moving at more than 85% the speed of light, though it was also “quite variable.” The observations, published this …

NASA’s Hubble Takes Census of Early Galaxies NASA’s Hubble Takes Census of Early Galaxies

Using the Hubble Space Telescope, astronomers have discovered seven previously unseen galaxies that formed over 13 billion years ago – a time when galaxies were just beginning to form. The new discovery has provided researchers with a “statistically robust” sample …

NASA Simulations Show How Wide Binary Stars Could Form NASA Simulations Show How Wide Binary Stars Could Form

Scientists with NASA‘s Astrobiology Institute team at the University of Hawaii have used computer simulations to reveal what causes binary stars to form. The researchers have concluded through their research that the widest binary star systems began as three stars, …
