An asteroid, called 2004 BL86, will sweep safely past Earth on January 26, 2015. The flyby is notable because 2004 BL86 will be the closest of any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027. This asteroid is estimated from its reflected brightness to be about 500 meters in diameter (about a third of a mile, or 0.5 km).
You think you’re pretty cool with your 13 or even 20-megapixel cameras on your smartphones – and those DSLR guys with their HDR shots, don’t get me started. Well, the SLAC National Accelerator Laboratory has both of them beat in getting DOE approval for the world’s most powerful camera.
Bright stars top Christmas trees in Christian homes around much of the world. The faithful sing about the Star of Wonder that guided the wise men to a manger in the little town of Bethlehem, where Jesus was born. They’re commemorating the Star of Bethlehem. The one big question for some astronomers every Christmas is what was the light that guided the Magi and is there any astronomical truth to the Star of Bethlehem?
New research suggests planets similar to Earth are much more common across the galaxy than previously thought. “Our solar system is not as unique as we might have thought,” says Courtney Dressing, graduate student at the Harvard-Smithsonian Center for Astrophysics.
The Year 2015 will be an exciting year for stargazers. Also, the astronomy calendar containing dates for most notable celestial events happening in 2015, including moon phases, meteor showers, eclipses, oppositions, conjunctions and other interesting events could help enthusiasts know when they will occur.
Far beyond the orbit of Neptune, trillions of comets left over from the formation of the solar system lie in wait in a region known as the Oort cloud. Here they are kept in relatively stable orbits around the sun, posing little threat to Earth save for the occasional icy rock that ventures inwards. But in the blink of a cosmic eye that could all change.
Keeping warm? 21/12 marked the start of astronomical winter for the northern hemisphere, meaning long nights and (hopefully) clear, cold skies. But we’ve also got another reason to brave the cold this week, as Comet C/2014 Q2 Lovejoy is set to put on a show for northern hemisphere observers.
Twins can be close, and that goes for stars as well as people. In some cases, stars get so close that they merge. In an unusual celestial event, astronomers have captured the image of two monster stars that may merge eventually and give us a chance to understand the theory on how supermassive stars are born.
When a star dies in a violent, fiery death, it spews its innards out across the sky, creating an expanding wave of gas and dust known as a supernova nebula. Arguably, the most famous of these supernova remnants is M1, also called the Crab Nebula, a blob-like patch visible in low-powered binoculars.
Sunny Sunday afternoons with clear azure blue skies, a promise of changing weather coming make me wonder whether we will see any of those Leonid meteors this week. If the clear skies prevail we can look forward to seeing some because the peak night is expected to be Monday, November 17 in the early evening-before bedtime!
This astronomy calendar of celestial events contains dates for notable celestial events including moon phases, meteor showers, etc… and other interesting events. Events on the calendar are organized by date, times given in Coordinated Universal Time (UTC) must be converted to your local time.
