A massive gate unearthed in Israel may have marked the entrance to a biblical city that, at its heyday, was the biggest metropolis in the region. The town, called Gath, was occupied until the ninth century B.C. In biblical accounts, the Philistines — the mortal enemies of the Israelites — ruled the city. The Old Testament also describes Gath as the home of Goliath, the giant warrior whom the Israelite King David felled with a slingshot. The new findings reveal just how impressive the ancient Philistine city once was, said lead archaeologist of the current excavation, Aren Maeir, of Bar-Ilan...

Archaeologists at Israel's Bar-Ilan University announced on Monday the discovery of a massive gate and other fortifications in the ruins of Gath, the hometown of the Bible's Goliath. The ancient gate is one of the largest ever discovered in Israel and evidence of the Philistine city's power in the 10th and ninth centuries B.C.E, head archaeologist Professor Aren Maeir says. It even made a brief appearance in the Bible when David, Goliath's slayer and future king of Israel, "acted like a madman, making marks on the doors of the gate and letting saliva run down his beard."

Explanation: If you're looking for something to print with that new 3D printer, try out a copy of the Homunculus Nebula. The dusty, bipolar cosmic cloud is around 1 light-year across but is slightly scaled down for printing to about 1/4 light-nanosecond or 80 millimeters. The full scale Homunculus surrounds Eta Carinae, famously unstable massive stars in a binary system embedded in the extensive Carina Nebula about 7,500 light-years distant. Between 1838 and 1845, Eta Carinae underwent the Great Eruption becoming the second brightest star in planet Earth's night sky and ejecting the Homunculus Nebula. The new 3D model of...
