Heads Up: NASA Says 4,700 Potentially Hazardous Asteroids Are Out There

This afternoon around 3 o’clock Central time, asteroid 2012 KA will fly silently past Earth at a distance of about 139,433 miles. That’s a little more than halfway to the moon and well out of harm’s way. 2012 KA was discovered only yesterday by the Mt. Lemmon Observatory as part of the larger Catalina Sky…

One Weird-looking Comet Plus A Constellation That Can Spell

Comet Garradd is one weird-looking comet. At the moment, because we see it high above the plane of our planet’s orbit, the two tails stick straight out of either side of its head. It’s not often you get to see a comet’s tails 180 degrees apart, but Garradd has been visible for so many months…

Garradd's two tails point away from each from a combination of the comet's location high above the plane of the planets and our perspective of it from Earth. Blue arrows show the direction the comet's moving along its orbit.  Credit: NASA/JPL with my own additions

Comet Garradd Pays A Visit To A Herculean Star Cluster

Binocular and telescope owners can watch a fine match-up of the sky’s current brightest comet – Comet C/2009 P1 Garradd – and the rich cluster M92 in Hercules tomorrow morning. The cluster belongs to an ancient group of spherical, star-packed clusters called globulars. Some 330,000 stars are jammed into a ball 109 light years in…
