It's a great time to go outdoors and look at planets. I have three glorious planetary portraits to share today, sent to me by amateur astronomer Jean-Luc Dauvergne.
In our last episode, we talked about what it’ll take to navigate across the Solar System. In this episode we scale things up and speculate how future civilizations will navigate to other stars and even other galaxies.
NASA and Bigelow Aerospace weren't able to get the space station's newest module up and running this morning. Another attempt could come as early as Friday.
I’ve said it before, and no doubt I’ll have many opportunities to say it again: If you like big, splashy, gorgeous astronomical photos, it’s hard to beat a ridiculously magnificent grand design spiral galaxy. And if you like ridiculously...Show More Summary
The Voyager data set is a gift to Earth that keeps on giving. This week, I've seen three great new images processed from this old data set.
NASA is set to fill a new space station module called BEAM with air Thursday morning. But does BEAM inflate, or expand?
In early 2012 a mystery literally erupted on Mars. Well, above it. Amateur astronomers viewing the Red Planet from Earth noticed weird features on the limb of the planet (the edge as seen from Earth) in March and April 2012. They appeared...Show More Summary
Commerce, Justice, and Science—the House of Representatives’ subcommittee that oversees NASA spending—just released details on how they would fund the space agency in 2017. Overall, the news for the space program is very good.
