Astronomers have found a nearby galaxy that’s roughly the same mass as the Milky Way, but somehow contains less than 1 percent of its stars.
The galaxy is so dim, it’s evaded detention for decades, and now the team behind its discovery has figured out how its lack of stars hasn’t ripped it apart - it’s made from 99.99 percent dark matter.

Once again, the holiday season is upon us. Unfortunately, this leaves a lot of us at a loss. First, it’s easy to get bogged down by the commercialism that surrounds the season. Second, it’s sometimes difficult to find something that is really meaningful. To that end, here are some science themed gift ideas that you can get your loved ones (or maybe use as a treat for yourself). Some are educational, others are science based charitable contributions, all of them are pretty awesome.

“Zeno Effect” Verified: Atoms Won’t Move When They’re Being Watched
Remember playing Super Mario Bros. 3 as a kid (okay, maybe as an adult, too) and encountering Boos? The sneaky ghosts would only move when you weren’t watching them. Well, Cornell physicists proved that, much like the fictional enemies from the Mario universe, a quantum system can’t change while you’re watching it.

The simple discovery that a piece of wire mesh can stop a flame in its tracks saved the lives of thousands of miners.
This demonstration shows how a simple lamp made of gauze could contain the open candle flames that miners used before 1815. With the safety lamp, any potential explosions would stay contained and never escalate to dangerous levels (although mining remained an extremely dangerous occupation).
Watch the whole demo and hear the full story here.
What a way to spend Christmas!
