I was never very good at science. Mostly because it was taught to me the same way math was taught to me: It wasn’t. I mean it was, technically. But not in a way that inspired me or held my … Continue reading
The Kepler Space Telescope found the oldest solar system in the galaxy. While digging through backlogged data from the Kepler telescope, scientists found Kepler-444, an 11.2 billion year-old star in the Milky Way orbited by at least five Earth-sized planets.
It turns out, like us, stars slow down in their old age.
That observation is the key to a new method astronomers are using to accurately tell the age of cool stars — stars that match the size of, or are smaller than, our own sun. In a study published Monday in the journal Nature, a U.S. team claims it can estimate the age of these stars to within 10 percent by measuring how fast the star is spinning. Continue reading
In 1995, the Hubble Telescope snapped a stunning photo in the Eagle Nebula, 6,500 light years from Earth. The photo revealed three gigantic columns of cold gas, illuminated by the ultraviolet light from nearby young stars. The Pillars of Creation became one of the telescope’s most iconic and popular images.
Black holes are some of the most exotic objects in our universe. But how do you see something that, by definition, you can’t see? The answer will take a telescope the size of the Earth. Continue reading
Using the ALMA radio telescope in Chile, astronomers were able to capture the formation of a new planet, and scientists are observing it happen more clearly than ever before. Hari Sreenivasan reports. Continue reading
It’s only a matter of time before a big comet or asteroid is on a collision course with Earth. Will scientists discover it, and be able to do something about it, ahead of time? Science correspondent Miles O’Brien talks to NASA astronomers who troll for trouble in the sky. Continue reading
Deadly altitudes, breathtaking skies, treacherous roads, wild donkeys — it’s all part of working on the most sophisticated telescope in the world. Continue reading
Beyond Earth’s atmosphere lurks a threat that could knock out our electrical grid and cause catastrophic structural, not to mention economic, damage. The risk within the next decade is about as great as that of another earthquake shaking California. So why haven’t we prepared? Continue reading
Two years ago, the worst solar storm in almost two centuries tore through Earth’s orbit. Luckily, the storm’s path just missed Earth. Continue reading
