While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using small telescopes to study a growing portion of the nearby univer
Comet C/2014 Q2 (Lovejoy), a long-period comet discovered by Australian astronomer Terry Lovejoy on August 17, 2014, is making closest approach to our planet today, at some 70 million kilometers (43.5 million miles / 0.469 AU) away.This comet is now a naked eye object a

Astronomers using NASA's Chandra X-ray Observatory have caught the largest X-ray flare ever detected from what is believed to be a supermassive black hole at the center the Milky Way, also known as Sagittarius A* (Sgr A*).The event was 400 times brighter than the us
Quadrantids are considered to be one of the best annual meteor showers, known for their bright fireball meteors – larger explosions of light and color that can persist longer than an average meteor streak.This year, they peak on the night of January 3rd and the morning
As far as the meteor showers are concerned the year starts with an above average Quadrantids, unfortunately the nearly full moon will block out most of the show. Quadrantids will peak this year on the night of January 3rd and the morning of 4th.Brilliant comet C/2014 Q2
