PLANET X NEWS

Brown dwarf stars are bizarre objects, which straddle the gap between fully functional stars, and massive planets like Jupiter. Brown dwarfs aren’t massive enough to start nuclear fusion in their cores, which is the process by which our own Sun reaches such tremendous temperatures. Without a large source of heat in their cores, brown dwarfs can’t do anything to maintain a stable temperature and cool over time as they radiate their heat away into the void. In many ways, we look to Jupiter as a model of what a small brown dwarf might look like. But, like many boundaries in astronomy, the border between a large Jupiter-like planet and a small brown dwarf is very, very fuzzy. Do you count a brown dwarf formed with a much larger, brighter star as a dual star system, or as a single one with a very massive planet? There are a few things we know should change. Brown dwarfs should be hotter than Jupiter, and this is largely because they contain more mass than Jupiter - typically at le

NASA administrator Jim Bridenstine believes the prospect of a killer asteroid colliding with Earth isn't something reserved for science fiction films. Bridenstine made the case for why the US should be fortifying its defense against meteor events on Monday at the 2019 Planetary Defense Conference in Washington, D.C.  It comes as NASA, the Federal Emergency Management Agency and other parties will conduct a defense drill at the conference that simulates what it would be like if an asteroid were heading straight for Earth. 'We have to make sure that people understand that this is not about Hollywood, it's not about the movies,' Bridenstine said at the conference. 'This is about ultimately protecting the only planet we know, right now, to host life and that is the planet Earth.' He pointed to the Chelyabinsk Event as evidence of the increasing seriousness and potential for these events. The meteor, which blazed across the southern Ural Mountain range in

Severe weather is affecting the Central United States since over the past couple of days, dumping heavy rain and hail, and producing damaging tornadoes. NWS warns severe weather will be possible across a broad area across the South and Central Plains, and lower and Middle Mississippi Valley today, May 1, 2019. Very large hail will be possible for a portion of west-central Texas, otherwise, damaging winds, hail, and heavy rain will be the primary threats. Late season Spring snow continues into Wednesday across the central Rockies and High Plains. AccuWeather meteorologists warn similar weather is expected to continue into May, the most active month for severe storms across the region. "Widespread severe thunderstorms broke today [Tuesday, April 30] out across northern Texas, central Oklahoma, northwestern Arkansas, and southern Missouri. Conditions were ripe for tornadoes to develop as several discrete supercells developed this afternoon," AccuWeather Meteorolog
