Want to see a comet whizzing by Earth? A great chance to catch one of these celestial visitors is overnight tonight, when Comet 21P/Giacobini-Zinner will be best visible in binoculars or a telescope. The comet, also known as "21P," will make its closest approach to Earth at around 2:30 a.m. EDT Monday (630 GMT). The bright-green comet should reach a visual magnitude of 6.5 to 7, according to EarthSky.org. This makes 21P almost bright enough to see with the naked eye — but not quite.

ISON UPDATE/Large Debris Moving Fast. Published on Dec 4, 2013 Ison Update. Solar and Quake Links http://www.BPearthWatch.ComPaul Begley Show Thursday 11 am - 2 pm Central time. LINK http://www.paulbegleyprophecy.com/web... Ison is a V shaped debris field with objects that are miles wide each..at least 21 large ones..They are moving at 2 million miles per day. Ison is moving away from "Secchi A" at that speed which makes it appear smaller from that camera each hour.. THE ROCKS ARE DARK NOW. They will become darker as they move further from the sun over Earth..They will not become smaller.

This Hubble Space Telescope model from 2003 shows us why. From afar, Comet 67P/Churyumov-Gerasimenko is a tiny object to image, even for the NASA probe’s powerful lens. Back then, the telescope was tasked with examining the comet to look at its size and shape to better design the Philae lander spacecraft. And the model reveals no duckie; it looks more like a sombrero from some angles. The main concern of scientists back then was redirecting Rosetta to a new target when its original comet (46P/Wirtanen) fell out of reach due to a launch delay. 67P was bigger and had a...
