Seemingly impossible, the idea of a nested star has been proposed before – it’s just nobody has ever found an example of the cosmic oddity. That may be about to change though. Scientists are keeping the name of the star a secret right now – at least until their peers can validate their findings – […]

Since who knows when, people have been watching the sky. It has been a means of tracking time, of navigating, of superstition, and a form of entertainment. Check out the giant list of interesting astronomy facts.
It’s a hauntingly beautiful phenomenon created by an unusually high concentration of Noctiluca scintillans (or Sea Sparkles), a single-celled bioluminescent algae of the dinoflagellate species that turns the water a brilliant, glowing, ethereal blue. Floating in swarms of millions and feeding on plankton and bacteria, it is believed that the Sea Sparkles generate their glow […]
On February 15, 2013 an asteroid about half the size of a football field will pass by the Earth with only 17,200 miles to spare. The asteroid, named 2012 DA14, will pass Earth closer than many man-made satellites. Don Yeomans of NASA’s Near Earth Object Program at JPL told reporters that this is a record-setting […]
Astronomers Valeri Hambaryan and Ralph Neuhӓuser have discovered proof that a massive short duration gamma-ray burst hit the earth in the 8th century. The intense blast of high-energy radiation could have caused a mass-extinction event if it had been just a tad bit closer to the earth. Scientists estimate that the event emanated from 3,000 […]
If you have ever wondered why, against conventional logic, black holes are so “light”, researchers at Virginia Tech may be about to quench your thirst for an answer. Computer models of the early universe fall fairly close to home except for one thing – the ratio of the mass of black holes in the center […]
Leonid meteor shower will have an unusual two separate peaks this week – November 17 and November 20
The annual Leonid meteor shower, one of the best annual meteor showers, will be reaching its peak this week although the showing is not expected to be spectacular with only 10-15 meteors per hour projected. This year the shower is a bit unusual with two peaks expected – one on Saturday morning (11/17/2012) and the […]
Two volunteer amateur astronomers have confirmed the existence of a Neptune-like planet that has four suns, making it the first quadruple planetary star system ever discovered and a real-life version of Tatooine from “Star Wars”. The planet is a gas giant located 5,000 light years from Earth and orbits one pair of the stars which […]
Astronomers have discovered a new planet, about the size of Earth, orbiting Alpha Centauri B, a nearby sun-like star roughly 4 light years away. The new planet orbits its parent star about 10 times closer than Mercury so temperatures might be more than 2,240 degrees Fahrenheit. Still, scientists are hopeful that more planets will be […]
Brightest comet (ISON C/2012 S1) in over a century is heading our way (but will probably not hit Earth) [UPDATE]
Russian astronomers have discovered a comet, named C/2012 S1, which is heading our way. It is scheduled to fly by Earth in December 2013. It is expected to be the brightest visitor to our solar system in over a century. Astronomers believe the comet will be considerably brighter than Halley’s Comet (1986) and Hale-Bopp (1997) […]
Each year, the Royal Observatory Greenwich‘s hosts its annual Astronomy Photographer of the Year competition. Now in its fourth year and growing, they received over 800 photo submission. Winners were announced on Sept. 19 in four main categories — Deep Space, Our Solar System, Earth and Space, and Young Astronomy Photographer of the Year — […]
A thousand foot chunk of rock, named Apophis, is on schedule to buzz the Earth on April 13, 2029. For those superstitious types, that’s Friday the 13th. Apophis is expected to pass a mere 23,600 miles from Earth which is a “close call” by astronomical measurements.
For those anxiously awaiting December 21, 2012, here’s a little thriller for you. In a few hours, an asteroid (named 2012 QG42) the size of three football fields will be making a close pass by Earth. We would have warned you earlier but, eh, the astronomy geeks just spotted it a few weeks ago.
Two separate sightings on Monday indicate something big happened on Jupiter. Two astronomers reported seeing a bright flash on the surface of Jupiter on Monday at 6:35 AM CDT. One astronomer, George Hall from Dallas, recorded the event which set the astronomer community abuzz.
Scientists have discovered a strange star that is not aging normally and seems to remain every youthful. In the picture below, the glowing cluster of stars in the center (known as the “globular cluster”) are all stars that astronomers think formed in the universe’s distant past. Astronomers can determine a star’s age by the presence […]
As part of the Mars Science Lab Mission (MSL), Curiosity is now sending back telescopic images from Mars. This image is from a test series used to characterize the 100-millimeter Mast Camera on NASA’s Curiosity rover. It was taken on Aug. 23, 2012, and looks south-southwest from the rover’s landing site. The 100-millimeter Mastcam has […]
