‘Maybe you’ll be going to Mars,’ Buzz Aldrin tells a 6-year-old Shiloh boy

‘Maybe you’ll be going to Mars,’ Buzz Aldrin tells a 6-year-old Shiloh boy

Lukas Pilkey was so excited last week he could have leaped over the moon. The Shiloh 6-year-old got to meet one of his heroes — retired Air Force Col. Edwin “Buzz” Aldrin. “It was really cool,” Lukas said with an ear-to-ear smile while donning a T-shirt with an astronaut on it. Lukas, his parents, Greg and Aerica Pilkey, and Aerica’s dad, Mike Dreps, stood in line for over three hours on Wednesday, Nov. 15 to get into the Center for Global Citizenship at St. Louis University to hear the famous astronaut speak.

These Photos From the Hubble Space Telescope Show Two Galaxies Colliding in Spectacular Fashion

These Photos From the Hubble Space Telescope Show Two Galaxies Colliding in Spectacular Fashion

Even after more than 27 years in space, the Hubble Space Telescope can still take one heck of a photo. The image above was taken earlier this year and shows two galaxies merging into one. Described by the European Space Agency and NASA as a "twisted cosmic knot" in the constellation Cancer, it's about 250 million light-years from earth.

Aircraft and helicopter in mid-air crash

An aircraft and a helicopter have crashed in mid-air over Buckinghamshire, the Air Accidents Investigation Branch (AAIB) said. Emergency services were called to the site near Waddesdon Manor, near Aylesbury, at 12:06 GMT. The AAIB said it was sending a team to investigate. Ambulance crews said there had been a number of casualties. A Wycombe Air Park spokesman said both aircraft involved came from the airfield near High Wycombe.

New pulsar result supports particle dark matter

New pulsar result supports particle dark matter

New results from an unconventional observatory in Mexico are bringing scientists one step closer to solving the dark matter mystery. They lend credence to the idea that some strange non-light-emitting particle is responsible for about 85% of the universe’s mass. This new observation casts serious doubt on the more conventional of two favored theories for the enigmatic excess of antimatter particles in space, leaving dark matter particles as the most likely explanation.

A broken heart can cause as much damage as a heart attack

A broken heart can cause as much damage as a heart attack

Severe emotional stress can prompt a sudden heart condition that poses the same sort of long-term damage as a heart attack, new research has found. Takotsubo cardiomyopathy – or “broken heart syndrome” – affects at least 3,000 people in the UK and is typically triggered by traumatic life events such as bereavement. During an attack, the heart muscle weakens to the point where it can no longer function as effectively.

Kill switches for engineered microbes gone rogue

Kill switches for engineered microbes gone rogue

Synthetic biologists are fitting the genomes of microorganisms with synthetic gene circuits to break down polluting plastics, non-invasively diagnose and treat infections in the human gut, and generate chemicals and nutrition on long haul space flights. Although showing great promise in the laboratory, these technologies require control and safety measures that make sure the engineered microorganisms keep their functional gene circuits intact over many cell divisions, and that they are contained to the specific environments they are designed for.

NASA Snaps Amazing Close-up Shot Of Antarctica’s Massive Iceberg

NASA Snaps Amazing Close-up Shot Of Antarctica’s Massive Iceberg

Last July, the world saw the amazing satellite images that showed an iceberg bigger than the state of Delaware drifting away from Antarctica’s ice shelf. Now it’s summertime in Antarctica, which is allowing scientists to view the massive ice structure up close. According to Gizmodo, the ice behemoth is known as “iceberg A-68” and weighs “about a trillion tons and features a surface area of 2,240 square miles (5,800 square kilometers).”
