The public is unaware there are two different smoke detectors.  It's an educational piece that seems to have fallen short, Reger said.He said it's in the consumer's best interest to educate themselves on what kind of smoke detectors are in the home. 254

The University of Maryland's astronomy department said that Comet 46P will be the 10th closest comet since 1950 because few comets are ever bright enough to be seen with the naked eye.The "Christmas comet" appears in our sky once every five years as it orbits the sun. It was closest to the sun on December 12. The comet is named for the man that first observed it in 1948, Carl Wirtanen, a senior observing assistant at California's Lick Observatory."Look towards the east with a small pair of binoculars or a telescope to see the green, fuzzy comet. It will be near the constellation Orion, or the saucepan," said Brad Tucker from the Australian National University Research School of Astronomy and Astrophysics.Much like watching a meteor shower, you'll want to be in an area without much light pollution. Look up anytime between twilight and sunrise to catch a glimpse.

It's three-quarters of a mile across with a core that's less than a mile wide. But the atmosphere around the comet, or coma, is bigger than Jupiter. When it passes the sun, this icy comet essentially experiences some melting. That's what creates the glowing green cloud.The diffuse nature of the coma and its glow may actually make it more difficult to view, especially if using binoculars or a telescope. Astronomers have predicted the comet will have a magnitude of 4.2, which means that a dark, clear sky and an absence of ambient light will most likely be needed to see it.And unlike other comet sightings, this comet's tail will be behind it when it passes, meaning we most likely won't see it unless the tail develops a curve before its closest approach to Earth.Comet 46P was originally chosen by the European Space Agency to land the Rosetta probe on its surface, but launch delays caused a new target to be selected. (Rosetta went on to land on Comet 67P in 2014.)"Wirtanen's comet could easily be chosen again for another mission," said Jim Lattis, director of the University of Wisconsin astronomy outreach center, UW Space Place. "So that means watching this comet each time it comes near could be important."Much like the OSIRIS-REx mission to study the asteroid Bennu, a remnant from the early solar system, Comet 46P could provide similar insight."We're getting a look at stuff that was formed during the formation of the solar system and has been out in the deep freeze since then," Lattis said. "When these things come in and we get a chance to study them, we're seeing some of the raw materials out of which the Earth and the other planets and everything else formed." 2795

The problem I have with bans like this is that they are not strategic, they are piecemeal. ... If this replaces (polystyrene), that's bad, Kersey said, holding aloft a plastic clamshell container. "The problem is littering. That's what we're not addressing here today." 269

The unclassified memos include the now-famous conversation Trump had with Comey where he told Comey, "I hope you can see your way clear to letting this go, to letting Flynn go." 177
