A supermassive black hole in the center of the Milky Way just woke up and is flashing 75 times brighter than ever observed, after being quiet for more than 20 years, baffling astronomers. Sagittarius A*, a supermassive blackhole that weighs about 4 million solar masses, is normally low key with minimal fluctuation in brightness. Recently, however, it bloomed 75 times brighter than ever before for... 

Using our current technology, it would take 180,000 years to reach Zarmina. But our resident physicist Dave Goldberg has a more optimistic estimate – thanks to antimatter and time dilation, astronauts could get there in just a few years. Dave calculates that, if we could build a stellar drive that gets its fuel from matter-antimatter explosions, then it would be possible to travel to Zarmina... 

Astronomers say they have for the first time spotted a planet beyond our own in what is sometimes called the Goldilocks zone for life: Not too hot, not too cold. Juuuust right. Not too far from its star, not too close. So it could contain liquid water. The planet itself is neither too big nor too small for the proper surface, gravity and atmosphere. It’s just right. Just like Earth. “This...
