Asteroids, as the dinosaurs found out, can have big effects on life on Earth. Sixty-five million years ago, an asteroid crashed into the Yucatán. The impact caused apocalyptic tsunamis and volcanic eruptions. Grit and ash blotted out the sun. It wiped out species that had roamed the Earth for millions of years.Yet asteroid hits also were critical t…

To make a black hole, you need to think big. Really big. Start with a star much bigger than the sun — the bigger the better. Then settle in, and wait a few million years for your star to die.That should do the trick, if you want to get yourself a garden-variety black hole. But there’s another kind of black hole. They are mind-boggling in size. And …

On September 15, 2018, the last Delta II rocket lifted off from Vandenberg Air Force base, in California. It carried into orbit IceSat-2 — a satellite equipped with perhaps the most sophisticated space laser ever built. NASA didn’t put it up there to shoot down rogue asteroids. Instead, it’s taking aim — with exquisite precision — at Earth.On this …

For a long time, probably as long as we have been gazing up at the night sky, people have been asking ourselves: Are we alone? Is there life out there, anywhere else in the universe?For modern Earthlings, our fascination with extraterrestrial life has focussed on one place in particular: Mars.The planet today is a forbidding, arid place. But billio…

On August 17, 2017, an alert went out. Gravitational wave detectors in Louisiana and Washington state had detected a disturbance from deep space. The effect was subtle — these detectors and a sister site in Italy measure disturbances smaller than a proton. But the evidence was dramatic. And the story they told was truly cataclysmic: A pair of neutr…

Scientists in 1985 discovered something that threatened the world we live in: The ozone layer had a hole in it. A big one. And this hole was growing very quickly. If it continued to grow, the consequences would be dire.Presented with the science, world leaders came up with an international agreement. The Montreal Protocol, as the treaty was called,…

In this darkest season of the year, Dr. Michelle Thaller and NASA astronomer Andrew Booth curl up by the fire. Gazing into the embers, red wine in hand, they consider the meaning of the winter solstice — on other planets. Like Uranus, where parts of the planet go 42 earth years without seeing the sun. Or Mars, where winters are made colder by an or…

NASA’S office of planetary defense isn’t worried about Klingons or Amoeboid Zingatularians. They worry about asteroids and comets. Like the one that exploded over Chelyabinsk, Russia in 2013. It was about 20 yards across. An asteroid 150 yards in diameter could take out a city. An even bigger one — as the dinosaurs reading this will attest — could …

These days, astrophysicists like Dr. Michelle Thaller use instruments to probe the distant reaches of our galaxy, and far beyond. They use interferometry, the Hubble space telescope, and other technology impossible to imagine when the constellations of the winter sky were named.

We live our lives in three dimensions. But we also walk those three dimensions along a fourth dimension: time.??Our world makes sense thanks to mathematics. Math lets us count our livestock, it lets us navigate our journeys. Mathematics has also proved an uncanny, stunningly accurate guide to what Brian Greene calls “the dark corners of reality.”??…

In a scary time, in a scary world, in a scary universe, NASA astronomer Andrew Booth says one of the things that frightens him most is math. Specifically, the unshaken power of mathematics to describe the universe. That’s because, beyond the comforting world of Newtonian physics, math gets mind-bendingly weird. So from the relative safety of their …

Remember the myth of Icarus? He and his dad were trying to escape from prison. Locked up on the Greek island of Crete, they made wings out of beeswax and bird feathers. They soared to freedom — but Icarus got cocky, flew too close to the sun, and fell into the sea. A few thousand years later, NASA is ready to do the job right.The Parker Solar Probe…

There was a time before planets and suns. A time before oxygen. You could say there was time, even, before what we think of as light.Back in 1989, the Big Bang theory was still in question. But that year, a NASA team led by cosmologist John Mather launched a mission to probe the earliest moments of the universe.Mather won the Nobel Prize in Physics…

NASA is relying on hi-tech lasers — and some vintage U.S. Navy hand-me-downs — to learn about the polar regions of a remarkable, watery planet. It's located in the Orion spur of our galaxy. NASA scientists have detected mountain ranges completely under ice. But the remaining mysteries of the ice here are profound, and what the science tells us coul…

Scientific discovery can happen in two ways: “Eureka!” moments of sudden understanding, where researchers glean unexpected insight into new phenomena. Or, a slower, less glamorous hunt for truth that happens day-after-day, for years. But both methods can lead to new understandings that pushes the field forward for future breakthroughs.In this episo…

Alex Young, Associate Director for Science in the…
