Breakthrough

This year we said goodbye to one of our most intrepid planetary explorers, the Opportunity rover. Take a look back at its storied 15-year mission on Mars, and how it revolutionized our understanding of not just the red planet, but our solar system at large.

MOSE is one of the world’s largest and highest-profile civil-engineering works. But will it be able to save Venice? Venice has grappled with inundation for centuries. But due to natural subsidence and higher tides caused by global warming the city is more vulnerable to flooding than ever before.

For all of human history, the Sun, our home star, has measured our days and our seasons while fueling all life on Earth. Yet it remains an enigma. NASA's Parker Probe Plus is on a mission to change that -- flying through dangerous radiation to become the closest spaceship to orbit our Sun.

Wildfires have greatly increased in size and intensity over the past few years. After record-setting conflagrations erupted in the region’s prized forests new tools using cutting-edge technology are being developed to help save property and lives.

Lions may be known as the kings of the jungle but it was saber-tooth cats that ruled over the Americas. New fossil evidence is shinning a light on the violent lives of these mysterious species.

The eruption of Mount Vesuvius is renowned for its decimation of Pompeii, but nearby, an equally impressive Roman settlement known as Herculaneum was lost to history. Today, the latest in technology is opening a wind to the past, as scientists digitally "unravel" the Herculaneum Scrolls.

Rip currents can appear without warning, turning an ideal beach outing into a horrific scene of chaos and panic. But groundbreaking new research could teach thousands of potential victims how to spot and escape these silent killers before it's too late.

The real impact of global warming is now being felt in communities around the world. Climate scientists explain what to expect where you live, and what steps might still be taken to reverse the climate crisis.

A ballistic missile test by India recently shot down one of its own communications satellites. With over 900,000 pieces of debris currently orbiting planet Earth, space trash has become a very real threat to ongoing missions.

66 million years ago, an asteroid slammed into Mexico’s Yucatán Peninsula, causing a dinosaur mass extinction. With over 700,000 asteroids in space, what's in store for humanity and our planet if it happens again?

One of the oldest known hominins in southern Africa. An almost complete skeleton dates back more than three million years. Found in 1994 in the Sterkfontein Caves near Johannesburg in South Africa, which form part of the “Cradle of Humankind”.

Heart disease is the number one cause of death worldwide but there are researchers frantically working to change that. Meet the people inventing the future of cardiac health from new ways of imaging the body to the possibility of 3D printing a functioning heart.

The Tyrannosaurus Rex is known as the king of the dinosaurs, but how did its reign begin? Meet Moros Intrepidus, a 180 lb., deer-sized ancestor to the T-Rex. Learn how the latest in paleontology can now link this small dinosaur to the 19,000-pound Scotty, the largest T-Rex ever discovered.

A non-profit organization established in 2011 is aiming to land the first Israeli spacecraft on the Moon. This is the story of their attempt and the excitement of being the first private company to have a spacecraft launched with the intention of going to and landing the moon.

How close are we to rendering infertility a problem of the past? Scientists believe that they are steps away from making healthy babies from stem cells, opening the doors for those with health limitations to become parents. But what are the legal and ethical implications of this breakthrough?

Wiped off the face of the Earth by humans nearly a century ago, geneticists are now working on resurrecting the enigmatic Tasmanian Tiger.

Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way...

Great white sharks are one of the most feared predators on Earth, and yet we know very little about them. Science is now revealing the mysteries of this perfect predator through evolutionary biology.

For the first time, scientists have captured a photograph of a black hole. The image verifies one of the most important theories in physics and will help unlock the greatest mysteries of the cosmos.

How long does it take for life to rebound after a major mass extinction? Scientists in Svalbard dig through fossil clues for surprising revelations about our Earth's history.

The Hayabusa2 spacecraft has just completed one of the most intricate procedures in space exploration. The first mission to deliver rovers onto an asteroid has now descended to its surface for a sample, before returning back to Earth in 2020.

The Greenland ice sheet the last remnant of the Ice Age is melting at an unprecedented rate. Today scientists and researchers from all over the world are paying close attention to what could become a global catastrophe.

The fate of the Mars InSight lander will all come down to a fiery seven-minute freefall into the Red Planet. Will it survive and reveal new insight into our planetary neighbor, or will the atmosphere of Mars prove to be too much for our new planetary explorer?
