So Chris Hatfield, a Canadian astronaut who’s currently at the International Space Station, cowrote a song with the Barenaked Ladies called “Is Somebody Singing?”
It’s about the wonders of space exploration and music, and it’s adorable.

Mystery Wave in Milky Way Galaxy Suggests Recent Crash
A mysterious wave discovered in the Milky Way suggests our galaxy is still ringing like a bell from a galactic collision, a crash that possibly occured within the last 100 million years, scientists say.
Astronomers discovered that stars north and south of the midplane of the galaxy are distributed differently, suggesting that some recent event perturbed them. The most likely explanation is that a small satellite galaxy or clump of invisible dark matter plowed through the Milky Way, leaving behind the echoes that we see.
“Our part of the Milky Way is ringing like a bell,” Brian Yanny, of the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill., said in a statement. “But we have not been able to identify the celestial object that passed through the Milky Way. It could have been one of the small satellite galaxies that move around the center of our galaxy, or an invisible structure such as a dark matter halo.”
Astronomers have spotted one of the rarest and most extreme galaxy clusters in the universe and, behind it, an object that shouldn’t exist.
NASA’s Biggest Rocket: Thrust Would Be Useful Now
Some of the more exciting plans for the future of space exploration are currently quite literally out of reach.
The United States doesn’t have the rocket power to send men to the moon or to Mars. There are some big rockets in the pipeline that will soon restore that power to the United States, but none can match the power of Nova. Nova was NASA’s first heavy launch vehicle that never made it to the launch pad — let alone off it.
