Landing 12 people on the Moon remains one of NASA’s greatest achievements, if not the greatest. Astronauts collected rocks, took photos, performed experiments, planted some flags, and then came home. But those week-long stays during the Apollo program didn’t establish a lasting human presence on the Moon.   More than 45 years after the most

Finally, scientists have found the source for a high-energy cosmic neutrino coming from outside our galaxy. The so-called mysterious “ghost particle”, detected on 22 September 2017, travelled 4 billion light-years to reach us, originating from an extremely energetic object called a blazar.   It’s an amazing discovery, one that not only confirms blazars as a

A mysterious cataclysm in a neighboring galaxy was spotted in the sky above Hawaii last week, sending astronomers around the world scrambling to understand the source of the staggeringly brilliant flash.   “I’ve never seen anything like this before in the local universe,” said Stephen Smartt, an astrophysicist at Queen’s University Belfast and a lead

The Fermi Paradox remains a stumbling block when it comes to the search for extra-terrestrial intelligence (SETI). Named in honor of the famed physicist Enrico Fermi who first proposed it, this paradox addresses the apparent disparity between the expected probability that intelligent life is plentiful in the Universe, and the apparent lack of evidence of extra-terrestrial intelligence

Almost all the large vertebrates on Earth suddenly went extinct 66 million years ago – including dinosaurs, mosasaurs, plesiosaurs, and pterosaurs. A city-size asteroid or comet is thought to be responsible for that mass extinction. The impact, called the Chicxulub event, triggered global cooling and volcanic eruptions that transformed Earth.   In the 1980s, Richard

Chris Hadfield, most widely known for his zero-gravity guitar-playing, has seen an impressive amount of space travel. Between his first spaceflight in 1995, his second in 2001, and a third in 2013, Hadfield has flown inside NASA space shuttles, a Russian Soyuz spacecraft, and the International Space Station.   Hadfield, who’s now retired, shares his

In 2006, NASA’s Mars Reconnaissance Orbiter (MRO) established orbit around the Red Planet. Using an advanced suite of scientific instruments – which include cameras, spectrometers, and radar – this spacecraft has been analyzing landforms, geology, minerals and ice on Mars for years and assisting with other missions.   While the mission was only meant to
