Astronomers may have found the impossible – a star within a star

// January 10th, 2014 // No Comments » // Astronomy and Space News

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 – […]

Giant list of interesting astronomy facts

// September 10th, 2013 // No Comments » // Science

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.

Bioluminescent microorganisms in our oceans – nature’s beautiful palette of sea sparkles

// August 9th, 2013 // No Comments » // General Science News

Bioluminescence at night

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 […]

NASA says incoming Feb 15 asteroid will be a “record-setting close approach”

// February 1st, 2013 // No Comments » // Astronomy and Space News

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 […]

Researchers discover proof of massive gamma-ray burst striking Earth in 8th century

// January 22nd, 2013 // No Comments » // Astronomy and Space News

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 […]

Researchers discover clue as to why a black hole’s mass is lighter than expected

// November 28th, 2012 // No Comments » // Astronomy and Space News

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

// November 13th, 2012 // No Comments » // Astronomy and Space News

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 […]

The impossible: first ever quadruple planetary star system discovered – by amateur astronomers

// October 17th, 2012 // No Comments » // Astronomy and Space News

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 […]

Scientists discover new planet orbiting our nearest neighboring star – Alpha Centauri B

// October 17th, 2012 // No Comments » // Astronomy and Space News

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]

// October 1st, 2012 // No Comments » // Astronomy and Space News

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) […]

Thousand foot chunk of rock passing dangerously close to Earth in 2029

// September 16th, 2012 // No Comments » // Science

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.

Asteroid to make close pass by Earth today

// September 13th, 2012 // No Comments » // Astronomy and Space News

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.

Jupiter may have just taken a hit for us

// September 11th, 2012 // No Comments » // Astronomy and Space News

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.

Strange star discovered that is not aging normally

// September 7th, 2012 // No Comments » // Astronomy and Space News

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 […]
