Fireball Lights Up Australian Sky, Scientists Looking For Meteor’s Remnants
Australian scientists are searching for the remnants of a meteor which burned spectacularly across the sky in Perth Tuesday night.
The unusual phenomenon was caught on camera by multiple spectators and described as a “fireball” on social media.
Curtin University professor Phil Bland told CNN it was “almost certainly” a chunk of an asteroid coming through the atmosphere, an event which he said occurs only a couple of times a year.
Bland is the founder of the Desert Fireball Network, a group of scientists working to track the path of meteors and asteroids across the night sky, with a goal to building a “geological map of the solar system.”
He called for anyone who finds an unusual lump of rock to give him a call, saying he’d be “chuffed” to find it.
“It will look strange, it will have a black crust on it and it’ll be kind of slightly rounded in a way that most terrestrial rocks aren’t. It will look distinct, it’ll look odd, also they’re usually a little bit heavier than average rocks,” he said.
Bland said while asteroids came through the atmosphere a few times a year it was rare for it to occur in heavily populated areas such as Perth.
“There are probably 50,000 or 60,000 meteorites in existence in the world’s museum collections, they are incredibly valuable materials, from a scientific perspective,” he said.
One witness told the Australian Broadcasting Commission (ABC) they had heard a “boom” before seeing the light in the sky.
“We just thought it was lightning to start with, but the boom that came after it was definitely not thunder,” she told ABC Radio Perth. “It shook the whole house, the windows, the dog went psycho.”
Unexplained 'Security Issue' Keeps National Solar Observatory Facility Closed Indefinitely 9/14/18
It's been more than a week, and a National Solar Observatory (NSO) facility in New Mexico is still closed for an undisclosed "security issue."
The NSO's Sunspot Solar Observatory, on Sacramento Peak in the southern part of the state, was evacuated last Thursday (Sept. 6), as was a nearby post office, according to the Albuquerque Journal. FBI agents have reportedly been investigating the site, and they're apparently keeping local law-enforcement personnel in the dark.
The Association of Universities for Research in Astronomy (AURA), which manages the Sunspot observatory with funding from the U.S. National Science Foundation, hasn't said much, either. The organization released a statement saying that AURA "is addressing a security issue" at Sunspot "and has decided to temporarily vacate the facility as a precautionary measure until further n…
FEMA to test system allowing Trump to send emergency alerts
The Federal Emergency Management Agency (FEMA) is testing a new system next week that allows President Trump to send messages directly to U.S. cellphones.
All major wireless firms and more than 100 mobile carriers are participating in the new Wireless Emergency Alerts (WEA) program that allows for presidential alerts, FEMA wrote in a Thursday statement.
“The EAS [Emergency Alert System] is a national public warning system that provides the president with the communications capability to address the nation during a national emergency,” FEMA said in a statement. ADVERTISEMENT
Compatible cell phones will receive a text message that reads “Presidential Alert" and “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.”
The EAS is also used with radio and television broadcasters, cable systems, satellite radio, and television providers, and wireline video providers, the agency said.
The WEA system…
Asteroids 2018 RY5 and RZ5 flew past Earth at 0.47 and 0.13 LD, one day before discovery Two newly discovered asteroids - 2018 RY5 and 2018 RZ5 - flew past Earth within 1 lunar distance on September 12, 2018, one day before they were first observed. RZ5 is one of the closest known asteroids to flyby us this year and RY5 one of the biggest (nominal distance <= 1LD).
Asteroid 2018 RY5 flew past us at 17:12 UTC at a distance of 0.47 LD / 0.00120 AU (179 517 km / 111 546 miles) and a speed (relative to the Earth) of 23.73 km/s.
It was also discovered by astronomers at Catalina Sky Survey on September 13. Its estimated diameter is between 3.1 and 6.8 m (10 - 22 feet).

U.S. EPA Scientist Fired For Trying To Tell The Truth About Climate Engineering And Fluoridated Water
The public has been trained and conditioned to believe that federal agencies like the EPA exist to watch over them and warn them of any potential dangers. This notion could not be further from the truth. Though there are honest and caring people within these agencies (like the scientist who has drafted the statement below), the institutions as a whole exist to hide threats from the population, not to disclose them. The majority of the public continues to convince themselves that if there was really anything they should be concerned about, someone, somewhere, in some federal public protection agency would tell them. The statement below should be a sobering wake-up call for us all. It is yet another confirmation of all that has been stated above. From global geoengineering to Fukushima, to toxic fluoridated water and lethal vaccinations, the public health and the health of our biosphere…
Hong Kong Crushed by Typhoon Mangkhut, Death Toll rises to 36 Hong Kong and southern China under red alert as biggest storm of the year makes landfall near Macau.
Hong Kong and southern China braced on Sunday as strong winds and heavy rain from Typhoon Mangkhut lashed the densely populated coast, a day after the biggest storm of the year left at least 36 dead in the northern Philippines, with dozens of others missing.
Nearly half a million people had been evacuated from seven cities in Guangdong province of China, and the Hong Kong Observatory warned people to stay away from the Victoria Harbour landmark, where storm surges battered the waterfront reinforced with sandbags.
Mangkhut made landfall in Guangdong on Sunday.
The national meteorological center said southern China "will face a severe test caused by wind and rain" and urged officials to prepare for possible disasters.
On Sunday morning, the typhoon packed sustained winds of 155 kilometers an hour and gusts of up to 1…
Sunspot Solar Observatory to reopen Monday morning 9/17/18 after FBI investigation SUNSPOT, N.M. - The solar observatory located in Sunspot, N.M. that was closed for safety reasons is scheduled to reopen after it was shut down while the FBI investigated the area.
According to a release by the Association of Universities for Research in Astronomy (AURA), the observatory will reopen Monday after criminal activity was reported at Sacramento Peak.
The release also stated that the investigation involved a suspect who AURA officials believed posed a threat to the safety of staff and residents that live nearby.
AURA has not released the current status of the suspect or any information involving the suspect.
ABC-7 learned the observatory had closed on Sept. 6 and that staff and some residents in the area were forced to evacuate.
According to AURA, they did not release any information about the closure because of the potential of alerting the suspect and impede the law enforcement inve…
Scientists: World's warming; expect more intense hurricanes A warmer world makes for nastier hurricanes. Scientists say they are wetter, possess more energy and intensify faster.
Their storm surges are more destructive because climate change has already made the seas rise. And lately, the storms seem to be stalling more often and thus dumping more rain.
Study after study shows that climate change, in general, makes hurricanes worse. But determining the role of global warming in a specific storm such as Hurricane Florence or Typhoon Mangkhut is not so simple — at least not without detailed statistical and computer analyses.
The Associated Press consulted with 17 meteorologists and scientists who study climate change, hurricanes or both. A few experts remain cautious about attributing global warming to a single event, but most of the scientists clearly see the hand of humans in Florence.
Global warming didn't cause Florence, they say. But it makes the system a bigger danger.
Severe typhoon hits Hong Kong, Southern China after taking at least 30 lives in the Philippines Typhoon Mangkhut rocked Hong Kong en route to mainland China on Sunday, lashing its coastline and sending skyscrapers swaying, after killing at least 49 people in the Philippines and ripping a swathe of destruction through its agricultural heartland. The world's biggest storm this year left large expanses in the north of the Philippines' main island of Luzon underwater as fierce winds tore trees from the ground and rains unleashed dozens of landslides. The number of people killed jumped to 49 on Sunday, police said, as more landslide victims were discovered. Police spokesman Benigno Durana released updated figures showing the number of dead had risen from the previously reported toll of 30. In Hong Kong, weather authorities issued their maximum alert for the storm, which rocked the city with violent gusts that have reportedly reached 145 miles per hour. As the storm passed south of Hong …
Florence weakens to a tropical depression but flash flooding is far from over
Florence weakened to a tropical depression as it marched inland, unloading a powerful mix of wind and rain on the Carolinas after killing at least 13 people.
Despite its weakening Sunday from a tropical storm, its relentless rain drenched already saturated areas as authorities warned the danger is far from over.
"The flood danger from this storm is more immediate today than when it ... made landfall 24 hours ago," North Carolina Gov. Roy Cooper said Saturday. "We face walls of water at our coasts, along our rivers, across our farmland, in our cities and in our towns."
Florence crashed ashore Friday morning in North Carolina as a Category 1 hurricane, and it has wiped out power to about 796,000 customers in that state and South Carolina.
It has trapped people in flooded homes, with citizen swift-water rescue teams from out of state joining local emergency professionals to try to bring them…
