Astronomers are crowing about the discovery of what they say just might be "the largest individual structure ever identified by humanity."

It's not a galaxy or a cluster of galaxies--nor even a galaxy supercluster. It's not even a structure in the usual sense. Rather, it's...

이 넓은 우주에 우리가 혼자인지 아니면 머리 좋은 외계인과 함께 사는지, 아무도 모른다. 하지만 외계인이 어떤 모습일지를 상상하는 건 자유다.

스페인 바르셀로나 대학의 우주학자인 퍼거스 심슨 교수는 새로운 논문에서 대부분의 지성 있는 외계 종족은 300kg을 넘을 정도로 클 것이라고 발표했다. 평균적인 크기가 "북극곰과 비슷한 정도"라는 것이다....

How big is the Milky Way? Way bigger than we thought, it seems.

Surprising new research suggests that our home galaxy is about 50 percent bigger than previously thought, spanning some 150,000 light-years across rather than the 100,000 light-years that has been the generally accepted number.

머피의 법칙보다 화나는 자가운전자의 악몽이 있다. 바로 세차한 날엔 반드시 비가 오더라는 진리. 그런데 비가 오면 저절로 세차가 되는 차가 있다면 어떨까? 아니면, 커피나 와인을 쏟아도 더러워지지 않는 셔츠가 있다면?

페인트를 도포한 것 만으로 이 천은 모든 물을 튕겨낸다.
