Astronomers have confirmed the existence of a triple-star exoplanet located 1,800 light-years from Earth. Planets parked in multi-star systems are rare, but this object is particularly unusual owing to its inexplicably weird orbital alignment.
Sure enough, astronomers have discovered even more of those mysterious fast radio bursts from outside the Milky Way galaxy. Scientists using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope have detected 13 different radio bursts, including six repeat bursts from the same location in a galaxy 1.5 billion light years away. Each of those bursts represents about 25 million times more energy than the Sun, and they were collected at the lowest frequencies yet (400MHz to 800MHz).
Powerful, influential figures exert a irresistible pull, gathering an entourage around them. It’s a pattern that repeats on celestial levels. Our planet has the moon, but also a host of other artificial satellites that we’ve used to boost Earth’s follower count. The sun has planets, moons, asteroids, and comets. But neither can compare to galaxies like our Milky Way, which not only hosts hundreds of billions of stars but also has additional satellites, entire dwarf galaxies that chill in our galaxy’s neighborhood.
Not to scare you, but you’re getting hit with radiation constantly. First, there’s just regular old light (yep, that’s a kind of radiation). Then there are low levels of higher energy radiation like the kind in nuclear reactors, including particles coming out of the soil and off of bananas. But the highest-energy radiation is the weirdest stuff. It’s literally out of this galaxy.
Count up all the stuff in a galaxy and you should have a pretty good understanding of how much light is being emitted. But that doesn’t seem to be the case for our own Milky Way. Our galaxy’s got a source of extra gamma rays, the highest-energy light, right in its center. And scientists don’t know where all that energy’s coming from.
With the exploding Note 7 battery fiasco, Samsung inadvertently did something that’s increasingly difficult these days: It made smartphones interesting for a flickering moment. Super interesting in fact. Besides the intriguing mournful saga of the Note 7, whose embarrassing recall cost the company billions, Samsung also set up a dramatic release narrative for the Galaxy S8. This wasn’t just another smartphone—this was a make-or-break device charged with saving a company in the throes of an existential crisis. A smartphone that screams at the void—yikes!
