Over a billion people in China and millions around the world are celebrating the the Chinese New Year – the most important of Chinese holidays – this week.

Just when you think Pluto couldn’t get any more fascinating, it does. NASA said on February 4, 2016 that numerous, isolated hills – possibly fragments of water ice from Pluto’s surrounding uplands – are floating on the nitrogen ice glaciers on the little world’s surface.
Finding star distances isn’t easy. Here’s how it’s done, and why astronomers recently modified the distance estimate to the famous star Betelgeuse.
On this episode of EarthSky News, an update on the idea that the early Earth collided with a Mars-sized proto-planet to make the moon. That and more. Join us.
Like a zombie, the Milky Way galaxy may already be dead but it still keeps going. Our galactic neighbor Andromeda almost certainly expired a few billion years ago, but only recently started showing outward signs of its demise. Why do galaxies stop forming stars, change their shape and fade away?
Asteroid 2013 TX68 is a small asteroid with an uncertain trajectory that will pass close to Earth on March 5, 2016. Although the distance of its pass is not precisely known at this time, scientists say they will soon precisely define its orbit. It could fly past Earth as far away as 9 million miles (14 million km) or as close as 11,000 miles (17,000 km). For comparison, the moon’s distance is about a quarter-million miles.
Saturn’s rings look solid through telescopes and for, hundreds of years, many thought they were solid. But the solidity of Saturn’s rings turned out to be an illusion. Now researchers have discovered another optical illusion related to Saturn’s rings. New results show that the denser-looking areas in the rings don’t necessarily contain more material.
