University of Leicester and The Royal Astronomical Society New theory advanced for how collapsed stars become polluted -- pointing to ominous fate that awaits planet Earth A decades old space mystery has been solved by an international team of astronomers led by Professor Martin Barstow of the University of Leicester and President-elect of the Royal Astronomical Society. Scientists from the University of Leicester and University of Arizona investigated hot, young, white dwarfs —...

Study Gives Insight Into How Skywalker's Tatooine May Have Formed
2014-01-31 13:03:26

Lee Rannals for redOrbit.com - Your Universe Online Tatooine, a fictional planet with two stars that is best known as the home of Luke Skywalker in the Star Wars movie franchise, may not be as farfetched as one might think. Scientists from the University of Bristol studied Tatooine’s real world counterparts: circumbinary planets. These planets, like Kepler-34(AB)b, have an orbit that encompasses two stars, and the latest study gives insight into what Skywalker’s home might have...

Brown Dwarf Binary System May Include A Hidden Planet
2013-12-17 04:15:33

redOrbit Staff & Wire Reports - Your Universe Online Analysis of the two brown dwarfs located closest to the sun suggests that there could actually be a third, previously undetected planetary-mass object, according to research published as a letter to the editor in the journal Astronomy & Astrophysics. Brown dwarfs, which are failed stars that have a mass of less than 8 percent the mass of the sun, are not massive enough to burn hydrogen in their centers. The system at the...

Astronomers Puzzled By Discovery Of Giant Planet Orbiting Distant Star
2013-12-05 12:56:55

[ Watch the Video: What Planet Has Astronomers Puzzled? ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found the most distant orbiting planet to date, and the puzzling discovery is effectively throwing a wrench in planet formation theories. Scientists reported in The Astrophysical Journal Letters that exoplanet HD 106906 b is orbiting its star at 650 times the average Earth-Sun distance. "This system is especially fascinating because no model of either...

Sunless Planet Found Wandering In Galaxy
2013-10-10 10:04:16

Brett Smith for redOrbit.com - Your Universe Online While most of the planets seen outside our solar system have been observed orbiting a distant star, one of the most recently discovered exoplanets found was seen wandering the depths of space without the warming comfort of a nearby sun. The newly discovered planet PSO J318.5-22 is 80 light-years from Earth and has a mass about six times that of Jupiter. According to a study in Astrophysical Journal Letters that described the discovery,...

Not All Rogue Planets Are Born Within Solar Systems
2013-08-20 11:30:55

Lee Rannals for redOrbit.com - Your Universe Online A team of astronomers say free-floating planets can be born freely, outside of an existing solar system. Previously, scientists believed free-floating planets, or "rogue planets," must have been ejected from existing planetary systems. However, telescopes at Chalmers University of Technology have helped astronomers discover not all of these rogue planets were created this way, but that some were born free. Scientists believe there...

Uwingu Kicking Off 'Adopt-A-Planet' Campaign
2013-05-02 17:53:25

Lee Rannals for redOrbit.com — Your Universe Online Uwingu announced on Wednesday the launch of the world's first "Adopt-a-Planet" campaign, allowing the public an opportunity to adopt planets. The space company's new open-ended campaign allows the public to adopt exoplanets in astronomical databases through Uwingu's website. The campaign coincides with its other campaign aimed at naming a planet. Uwingu has asked participants to vote on names for exoplanets, which costs money....

How Planets Form: Your Universe Today Podcasts

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Starting in early 2013, redOrbit will be launching a new podcast series called Your Universe Today, where we interview leading scientists about cutting-edge research in everything from space travel to the origins of our Universe. But we´re in the holiday spirit and couldn´t wait until January to unveil our new podcast project, so we´ve decided to give you a sneak peak of what´s to come. In...

Lee Rannals for redOrbit.com [ Watch the Video: The Birth of a Planet Simulation ] Planetary researchers have a new tool in their artillery when trying to hunt for extrasolar planets. Scientists can now use simulated models developed by a group of scientists of how planets are born, helping the hunt for extrasolar planets. Planets generally form when a molecular cloud collapses into a young star. As the leftover gas and dust form a disk around the star, the particulates inside...

Pluto Demoted From Planetary Status Five Years Ago Today
2012-08-24 12:54:31

Lawrence LeBlond for redOrbit.com - Your Universe Online On August 24, 2006, the solar system´s most distant family member -- tiny, isolated icy planet Pluto -- received some shocking news: it would no longer be considered a true planet. The ruling spurred a hotbed of controversy, with many experts disagreeing with Pluto´s new status as a “dwarf planet.” Despite the controversy and oppositions from scientists and laypeople alike, the ruling went through, reducing...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
