This rogue black hole is flying through space, eating everything in its path

Added: 26.03.2017 7:01 | 1 views | 0 comments


Supermassive black holes are one of the scariest, most destructive and utterly intimidating forces in the universe, but the good news is that they usually don't do a whole lot of moving around. They often reside at the center of large galaxies, like our own Milky Way, with a gravitational pull keeps us all swirling around it. So what could be more frightening than a stationary black hole? How about one that is flying through space like a colossal vacuum, sucking up whatever it happens upon? Astronomers think they've spotted one doing exactly that. Researchers using the ever reliable Hubble Space Telescope compiled data gathered by the device and compared it with readings from the Chandra X-ray Observatory and the Sloan Digital Sky Survey, all of which support the theory that the supermassive black hole at the center of quasar 3C 186 has gone rogue. The quasar — which is the cloud of gas and material surrounding a black hole — was spotted a significant distance from the center of the galaxy it is believed to have helped form, meaning that some extremely powerful force has caused it to fly free. Using the positional readings of the quasar the scientists were able to calculate an estimated speed that they believe the black hole is moving, and it's pretty insane. The giant celestial object is cruising along at a breakneck speed of approximately 4.7 million miles per hour. If we were able to travel at that speed, astronauts could travel from Earth to Mars in just over seven hours. Thankfully, space is big, and the rogue black hole doesn't pose any immediate threat to our own galaxy. At least for now.

| The bangs, crackles and hums of Earth's seismic orchestra

Study gets to the bottom of ‘musical symphony’ produced in regions prone to mega-quakes as scientists work toward better quake hazard forecasting
You are at a classical music concert. There is an orchestra with three main sections. High up at the back, the percussion section has one very loud, large and moody-looking drum that gets struck very rarely. A handful of triangles produce occasional quieter “tings”. Further down, in the middle, there is a small band of violinists, but they are playing the strings so slowly the audience can barely hear them. Down at the front, a family of double bass instruments produces low-pitched, gentler hums from time to time.
This somewhat unconventional orchestra is like a type of tectonic plate boundary known as a subduction zone. Subduction zones delineate the battle lines between the collision of two titanic tectonic plates. Yet, this encounter is rather one-sided. One plate firmly stands its ground; the other sinks into the depths of the Earth. The grinding and sliding of these two plates produces a musical concert that can be detected by sensitive geophysical instruments and by humans during large quakes. The shallow parts of subduction plate boundaries can produce devastating mega-earthquakes with magnitude eight or greater (like the giant drum in the percussion section). In the tens to hundreds of years between these massive quakes, scientists eagerly listen to the signals at subduction zones to estimate whether the plate boundary fault is primed for a future quake, and to forecast what a rupture may look like.

Scientists make the case to restore Pluto's planet status

Added: 26.03.2017 2:08 | 2 views | 0 comments

Kirby Runyon wants to make one thing clear: regardless of what one prestigious scientific organization says to the contrary, Pluto is a planet. So, he says, is Europa, commonly known as a moon of Jupiter, and so is the Earth's moon, and so are more than 100 other celestial bodies in our solar system that are denied this status under the prevailing definition of 'planet.'
