Two cool nighttime photos by astronauts aboard the ISS. Check out the bright city lights.
North America has a ringside seat to the partial eclipse of the sun on October 23, and this eclipse is almost exclusively visible on land from North America. Eye safety is of the utmost importance in observing this solar eclipse, or else you risk eye injury or blindness. Click on the links in this post to find out more.
The human dream of travel to Mars and beyond seems closer than it’s ever been. But a new study announced by the American Geophysical Union on October 21 suggests that these plans might need to be delayed, or at least significantly altered. The reason? Increasing levels of cosmic radiation spurred by decreasing activity on our sun.
The peak of the annual Orionid meteor shower has now passed, but you might see some meteors still from this shower if you’re looking in a dark country sky. That’s because Earth is still moving through the orbit of Comet Halley, which last returned near Earth in 1986 and which is due to return again in 2061. This comet spawned this annual meteor shower by leaving bits of dusty debris behind in its orbit. Each year when we intersect the orbit of Comet Halley, we see the Orionid meteor shower!
You’ll see the Small Magellanic Cloud from Earth’s Southern Hemisphere. It’s even farther to the south than its larger cousin, the the Large Magellanic Cloud . These two hazy patches in the southern sky are really separate galaxies from our Milky Way. They are satellite galaxies to the Milky Way, orbiting around it. Follow the links below to learn more about the Small Magellanic Cloud.
To kick off the Halloween season of candy consumption, costume concocting and ghost story telling, I present to you a most fiendish lifeform, one that lurks in the dark and spooky rainforests of southeast Asia leeching life from innocent tree roots: a strange entity known as the corpse flower.
A team led by astronomers has created the first three-dimensional map of a section of the universe 10.8 billion light years away, when the universe was only a quarter of its current age. This map, built from data collected from the W. M. Keck Observatory, is millions of light-years across and provides a tantalizing glimpse of large structures in the ‘cosmic web’ – the backbone of cosmic structure.
Weather permitting, almost everyone in North America will be able to see the partial solar eclipse this Thursday. Here’s more info, including when to see the eclipse where you live
Hurtling through space at about 35 miles (56 kilometers) per second, Comet Siding Spring (C/2013 A1) swept closest to Mars on October 19, 2014. It swept extremely close to the planet, closer than any known comet in recorded history. We’re just beginning to see the photos from this event. See the best ones here …
