Asteroids Are Coming: Do You Know Where Your Children Are?

In fact, it is astéroïdo day happens Friday, June 30 and you want your children to pay attention. You too.

Really? As if climate change Brexit, Trump, North Korea, possible trade wars and all that was not enough, you have to worry about asteroids coming to the planet?

You are right. In fact, earlier this month, June 6, an Object Near Earth – NEO or as they are known – the size of a football field was as close to us as the Moon.

In April, another well-known JO25 2014 and about 2000 feet in diameter, the size of Gibraltar rock, approved by the planet at a relatively close distance of 1.1 million miles, approximately 4 1/2 times that of the Moon.

And as the asteroids approaching the ground several times a week, this was the largest since 2004.

These rocks – smaller and especially the parts of the formation of the universe (move their head around it) – are going to close several times a week and usually pose no threat to the Earth. On average, an asteroid the size of an automobile collides with Earth’s atmosphere every year, it burns in a spectacular fireball.

About 2 000 years ago, a football field asteroid hits the planet and damages.

There have been two major strikes in relatively recent times that show the power of the threat. More recently, on February 15, 2013, a 59-foot, 10,000-tonne meteor that moved around 40 by 000 mph exploded in a blinding flash 14 1/2 miles from Chelyabinsk, Russia. The people on the floor have felt their heat.

In the 20th century, the greatest known impact of human history was a meteorite or asteroid that exploded three to six miles above an area near the Tunguska River in Siberia, flattening about 770 square miles of forest. No human being hurt.

It was estimated between 200 and 620 feet in diameter. It is believed that energy equivalent to 1000 times that of the atomic bomb on Hiroshima fell.

Now consider this: attacking any meteor between 1 and 1 1/2 miles in diameter would have a global impact.

No more sweating? The meteor that hit the ground eventually erase dinosaurs and trigger mass extinctions, no more than six miles and has published about a billion times the energy of the Hiroshima bomb.

Trembling thoughts.

The Tunguska incident took place on June 30, 1908. This is why the founders of the Asteroid Day were established on the same date every year worldwide to illuminate the dangers NEO can present to a world that was not enough to Map the location of the millions of NEOs in our solar system that have the potential to hit the planet and even the destruction of a city.

Specifically, only 10 000 were found – only 1%. This explains the “100x Declaration” signed by 40,000 citizens, including 200 scientists and cultural personalities in the world, including a multitude of astronauts, Nobel laureates, facilitators and entrepreneurs.

Solar Eclipse 2017: Alaska Airlines Flight Will Offer View Above the Clouds

Emphasizing the clouds prevents seeing the total solar eclipse that will come? A group of lucky astronomy fans can feel comfortable.

While the moon blocks the sun’s face on August 21, leaving only the bright crown in the sky, they watch 35,000 feet (10,700 meters) in the air aboard an Alaska Airlines charter flight.

“We are in a unique position to provide a unique experience for astronomy lovers,” said Sangita Woerner, Alaska Airlines vice president of marketing, in a press release. “Flying over the Pacific Ocean provide not only one of the first views, but also one of the best.”

The flight should take off from Portland International Airport in Oregon at 7:30 am local time on August 21.

This will lead to the Pacific coast early to see the total solar eclipse, the first to cross from coast to coast for 99 years. [What they will see during the total solar eclipse of 2017]

The airline does not sell tickets to its observation group. Seats are available only by invitation to a select group of astronomers and guests.

But Alaska Airlines give two seats as part of a marketing promotion from July 21, the company’s social media.

“We still do not know how many people are going to be on board,” Halley Knigge, an Alaska Airlines spokeswoman for Space.com, said in an e-mail.

“The plane has a capacity of 181 guests, but limit the seats available to provide an optimal viewing experience for people on board. It is safe to say that there will be less than 100 people on the flight, including crew.”

Alaska Airlines also offered a flight to eclipse last year, in which Space.com columnist Joe Rao, was a passenger. The video of that flight, shown below, was shot by Mike Kentrianakis with the American Astronomical Society.
During the eclipse of August 21, the moon will pass between the Sun and Earth, blocking the solar disk and leaving only its faint outer atmosphere visible. If time allows, millions of people can see how the shadow of the Moon (113 km) reached 14 states, beginning at 10 am PDT 15 (17 h 15 GMT) in Oregon and ending at 2:49 pm. EDT (1849 GMT) in South Carolina.

The trajectory of the whole is progressing rapidly. Even lucky airline passengers can follow the eclipse, which will cross the country, at speeds of up to 2,900 km / ha in western Oregon at 2,400 km / h near Charleston, South Carolina, according to an interactive Google map created by Eclipse of the French Xavier Eclipse Jubier, with the eclipse defense group of the International Astronomical Union.

Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other

Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other

Do you think our galaxy is special? Ha. Our drilling roll of gas and dark matter could be a good place for humans.

But within hundreds of light years, there is an elliptical galaxy, Galaxy 0402 + 379, that supermassive black holes are orbiting just 24 or more years of light. Their combined weight is about 15 billion times that of our sun.

If not convinced, a team led by scientists at the University of New Mexico has actually detected black holes moving relative to each other using the Very Long Baseline Array, a system of ten radio telescopes in the United States, with locations in Hawaii And the Caribbean.

Not only is it the first direct measurement of the galactic centers orbiting that way, but it was a difficult calculation to realize.

One of the study’s authors, Roger Romani of Stanford University, told Gizmodo: “I think it’s a tour de force technique to measure such movement in the sky,” a-t said. “It took me ten years of measurement with the largest telescope network on earth.”

These black holes are large, probably a few thousand times more massive than the monster in the center of the Milky Way, Sagittarius A *. They are probably the result of a set of fused galaxies, according to Romani.

And although they are 24 light-years away, it’s actually a very narrow range in regards to the orbit of black holes. “Two approaching black holes are quite exceptional,” he said. Even so, it would take about 30,000 years for the giants to complete a full orbit. The researchers published the results in The Astrophysical Journal.
Capturing a movement of this type of distant sources in the sky requires using the VLBA, a radio telescope set up to perform very long base interferometry or VLBI.

In essence, the Earth itself is transformed into a telescope, but instead of focusing light on a mirror as a simple telescope, light is captured on individual radio telescopes and the focus is by comparing the information contained in supercomputers . These types of observations allow researchers to solve very remote but relatively important things.

Other researchers were delighted to observe. “This is an absolutely wonderful result.This is a very convincing proof of what would be the first binary black hole known visual observed supermassive,” meaning a pair of very solid black holes that can be solved separately with a light telescope Grant Tremblay, an astrophysicist at Yale University and Harvard Gizmodo.

“It will be very convincing target tracking for years to come.” Romani emphasized that studying binary black holes like these could help understand how black holes are joining in the center of large galaxies.

Another astronomer Sarah Spolaor at the University of West Virginia explains how these binary black holes are hard to find and none of the candidates is not completely confirmed (though this one). She always thought this observation was exciting.

“Its target source 0402 + 379 … is one of the most credible candidates for a number of reasons, perhaps one of the highlights is that it has actually been” photographed “and we can see the material clearly mark the two holes Blacks, “he said.

“Therefore, the discovery of the orbital motion at 0402 + 379 would be a dream come true for many,” and perhaps one day scientists may be able to make a video on the radio waves of orbiting black holes.

He emphasized that “the orbital movement is not the only possible explanation of what they saw,” Romani said. You will feel more confident after taking more data for longer. Or maybe they can find another pair in orbit.

With a Better Brain, Curiosity Mars Rover Picks Its Own Targets

With a Better Brain, Curiosity Mars Rover Picks Its Own Targets

The Curiosity Mars Rover is now smart enough to choose its own exploration targets, according to a new study.

The secret of Curiosity’s best brain was a software update sent to the ground in October 2015, called Stand-Alone Exploration to Collect Enhanced Science (AEGIS).

This was the first time that artificial intelligence had been tested on a remote probe, and the results showed that similar AI techniques could be applied to future missions, according to NASA scientists working on the project.

AEGIS allows the rover to be “trained” to identify rocks with certain characteristics that field scientists want to investigate. This is valuable because human Curiosity controllers can not be in direct contact with the mobile all the time.

Instead of waiting for instructions to “go there and sample this piece of rock”, Curiosity can now search for goals, even if it is not in contact with its human controllers, according to a new study that describes Curiosity use of the software.

“We can not be in constant contact with the rover – Mars turns and when [Curiosity is] on the opposite side, we can not get in touch with him,” said Raymond Francis, senior system engineer for the deployment of AEGIS . .com.

According to the study, once the AEGIS system was deployed, it was used 54 times between May 13, 2016 and April 7, 2017. Without intelligent targeting, curiosity could be expected to reach a goal Scientists are interested in about 24% time; With AEGIS, the rover managed 93 percent, according to the study.

Even when the rover is in contact, signals from Earth to Mars take the time to get there and come back. In May 2016, Mars was the closest it came from Earth in 11 years – 46.8 million miles.

A radio signal would take a little more than 4 minutes to get there and four more to come back. So if there are planetary scientists who want to take a closer look, it may take some time to send the orders.

Inactive time is often lost for mission rover time, and because sending a robot to Mars is expensive and difficult, it’s not ideal. A few hours hanging around each day may not seem like much, but it adds up during an entire mission.

With AEGIS, the rover could lead to a location, select investigative targets and collect data while waiting for radio contact with the Earth again. This means that terrestrial scientists are free to choose a new target once they re-establish contact with the rover.

For the study, the NASA team formed Curiosity, with the AEGIS software, to analyze the pedestal in a function called the Murray Formation after each training. The Murray Formation is a rocky outcrop with characteristic bands of stones, possibly laid by lakes of liquid water.

One question scientists wanted to answer was whether the chemical composition of the Murray Formation changed over time, as this might reveal changes in water chemistry, disclosing more about the history of water on Mars.

Study links at-risk orcas’ failed pregnancies to scarce food

Study links at-risk orcas’ failed pregnancies to scarce food

SEATTLE – Endangered killer whales attending Washington state inner waters have pregnancy problems because they can not find enough fish to eat, according to new research.

The researchers analyzed the hormones in feces collected at sea and found that more than two-thirds of the killer pregnancies failed over a seven-year period. They joined these problems to nutritional stress caused by a small amount salmon Chinook, the preferred whale system.

“A lot of whale design, but when nutrition is poor, we do not experience these pregnancies,” said Sam Wasser, lead author of the article and professor of biology at the University of Washington.

Southern resident breeders along the west coast of the United States have fought since they were listed as endangered species in 2005. They represent only 78, below a decade of the decade. Whales face threats of lack of food, pollution and ship.

The new study, which will be published on Thursday in the journal PLoS ONE focuses on providing food as a major stressor among which consumption of fish to whales. Unlike other killer whales they eat marine mammals, orcas that spend the summer in Puget Sound mainly feed on salmon, especially Chinook.

Many species of Chinook salmon along the west coast are classified as threatened or endangered because of a number of factors, including loss of habitat for urban development, dams, fishing, pollution and competition from fish Not native.

The toxins that accumulate in the fat of the whales that are released when the animals are weakened and metabolized this fat plays a role in the problems of pregnancy.
“Food is the driver. But what we still can not say is how it is affected by its interaction with toxins,” Wasser said, adding that there were not enough samples to tell how much toxins are influential.

The use of trained dogs to sniff poop whale, a team of scientists collected about 350 stool samples from 79 single whales in the inland waters of British Columbia and Washington State between 2008 and 2014.

In the laboratory, the hormones progesterone and testosterone were analyzed and evaluated whether orca was pregnant and at what time. They also used DNA to determine the whale’s identity, gender, and family line. The pregnancy is considered satisfactory if the female whale was later seen with the calf.

Their analysis showed 35 orcas pregnancies between 2008 and 2014. The eleven calves were seen with their mothers when the births were successful. Puget Sound killer whales can be individually identified and tracked intensely, so researchers know when the offspring are born in one of the three orcas families, known as the J, K, and L pod.
The study found 24 failed pregnancies. No calves were observed in these cases, indicating that whales have lost babies or calves died soon after birth. These women showed signs of nutritional stress – more than those who delivered correctly.

The researchers also recorded the number of vessels in the area collecting whale droppings. We studied two hormones that play an important role in physiological stress and were able to differentiate stress from poor diet and stress from boat traffic.

The team compared hormonal data to the abundance of two Chinook salmon records in the Pacific Northwest.

Data over time suggests that orcas have experienced periodic nutritional stress, partly caused by the change of time and soundness of courses salmon in the Columbia and Fraser rivers, according to the study.

The study said that improving these Chinook salmon migrations could help save the orcas in Puget Sound.
