We humans have done a pretty good job of trashing the Earth all by ourselves, but we don’t often stop to consider external threats – like asteroids . A 1908 asteroid explosion over Tunguska, Siberia ravaged 800 square miles, and Queen’s University Belfast astrophysicist Alan Fitzsimmons said another asteroid collision is simply a matter of time, which could have devastating consequences if we remain unprepared. He said most of us don’t think about asteroids as a threat to our existence. We now remember the day of the 1908 asteroid strike as Asteroid Day . It’s June 30, and Fitzsimmons is joining other experts like physicist Brian Cox and International Space Station astronaut Nicole Stott to call attention to the threat. Fitzsimmons says it’s not a matter of if an asteroid will impact the Earth, but when. He said a strike like the Tunguska one today could demolish a mayor city – and a larger asteroid strike could be even more devastating. Related: NASA rolls out new asteroid detection program to defend Earth from destructive meteors Fitzsimmons said in a statement, “Astronomers find Near-Earth Asteroids every day and most are harmless. But it is still possible the next Tunguska would take us by surprise, and although we are much better at finding larger asteroids, that does us no good if we are not prepared to do something about them.” He said experts have gotten much better about detecting Near-Earth Asteroids, and have found more than 1,800 objects that could be potentially hazardous. But there are more out there – and we need to be prepared. Fitzsimmons is part of a European Research Council-funded project, NEOshield-2, whose mission is to figure out how to deflect the hazardous asteroids. Asteroid Day events will be live streamed here . There will be conversations with space agencies like NASA and a Neil deGrasse Tyson-narrated video series on scientists laboring to protect Earth from asteroids, to name a few. The organization says it will be the first 24-hour live broadcast about space ever. Via Queen’s University Belfast Images via Asteroid Day

132-year-old lobster returned to ocean after living in tank for 20 years

Comments Off on 132-year-old lobster returned to ocean after living in tank for 20 years

Did you know it’s National Lobster Month? Residents in Hempstead, New York are celebrating the occasion by releasing a captive lobster back into the ocean . Louie the Lobster is 132 years old, but he has spent the last couple of decades living at Peter’s Clam Bar in Long Island . Louie, who could’ve fetched a fair sum at 22 pounds, will get to live out the rest of his life in the wild. Louie lived in a tank at Peter’s Clam Bar for around 20 years. Owner Butch Yamali obtained the lobster when he bought the restaurant four years ago. He says a customer recently tried to purchase Louie for $1,000 for a Father’s Day dinner, but Yamali couldn’t take the money, saying Louie has become like a pet to him.

Hempstead held a pardoning ceremony for the lobster as he was lowered into his new home in the Atlantic Ocean . In a ceremony for Louie, Hempstead Town Supervisor Anthony Santino said, “Today I’m announcing an official pardon for Louie the Lobster. Louie may have faced a buttery fate on a seafood lover’s plate, but today we are here to return Louie to a life that is better down where it’s wetter.” While sending animals to the wild from captivity right away isn’t always the best idea, Louie did live in the ocean for over 100 years before he was caught. Lobster Institute executive director Robert Bayer said, “He’ll be just fine. There aren’t many predators who want to eat a big old lobster like that. Hopefully, he finds a mate – and lives happily ever after.” Around a year ago Larry, another incredibly old lobster who’d been living at Peter’s Clam Bar, also found a new home in the ocean.

UN releases inconceivable new estimate of Earth’s 2050 population

Comments Off on UN releases inconceivable new estimate of Earth’s 2050 population

Right now there are 7.5 billion people on Earth and counting. But the world in 2050 will be even more packed, according to new United Nations (UN) projections. The new World Population Prospects: 2017 Revision report estimates that there could be nearly 10 billion people on the planet in a little over 30 years. By 2030, the global population could be 8.6 billion, according to the UN. 9.8 billion people might reside on Earth in 2050, and 11.2 billion in 2100. As around 83 million people are born every single year, the organization expects the total population to rise even if fertility levels go down. And while China currently has the most people of any country, the UN estimates India will surpass China in around seven years. Related: Earth’s population just hit 7.5 billion people Of the world’s 10 largest countries, Nigeria is growing the fastest. The country is currently the world’s seventh largest but the UN estimates they will surpass the United States to become the world’s third largest country just before 2050. And between now and 2050, around half of all the population growth on Earth will be centered in only nine countries: Nigeria, India, the Democratic Republic of the Congo, Ethiopia, Tanzania, Uganda, Indonesia, Pakistan, and the United States. The new report doesn’t just cover the amount of people in the world. It addresses fertility, life expectancy, and refugee movement. For example, fertility has fallen in almost all the areas of the world, even in Africa. One exception is Europe. A reduction in fertility has led to an aging population. Meanwhile life expectancy has risen globally from 65 to 69 years for men and 69 to 73 years for women, although the UN noted large disparities between countries in those figures. The UN Department of Economic and Social Affairs, Population Division put out the June 21 report. The organization says the statistics could help agencies better work to achieve the Sustainable Development Goals. Via the United Nations Images via Guillaume on Flickr and Wikimedia Commons

Chinese Researchers Plan to Use a Solar Sail to Save Earth from Asteroid Collision

Comments Off on Chinese Researchers Plan to Use a Solar Sail to Save Earth from Asteroid Collision

Chinese researchers plan to build a solar sail-powered spacecraft that will launch into space in the near future on a suicide mission to save planet Earth. Now, stay on your toes, this gets tricky. There is an astroid, called Apophis, that is headed straight into our orbit in 2029. Predictions in 2004 said that this astroid in question would most likely hit the Earth or the Moon, possibly destroying all life on our planet. Additional observations said that Apophis, deadly astroid, was actually most probably not going to hit us in 2029, but would definitely whip back around through a “keyhole” in the solar system and hit us in 2036 — maybe ending all life on planet Earth. That is, unless the Chinese plan works out — if it fails, the Europeans are planning a deflecting game of their own, which they’ll be trying out in 2015 .
