While it doesn't emit, absorb, or reflect light, we know dark matter exists because of the way its gravity affects visible matter. Galaxies rotate faster than they should based on the mass we can see, and large-scale structures in the universe form in patterns that only make sense if th...
While it's relatively straightforward to identify the shapes of planets, moons and galaxies, it's more complex to measure the shape of the universe. In fact, this question has a very counterintuitive answer, because when we think of the shape of something, we might imagine an object seen fr...
Nearby stars are valuable scientific targets, and in our galaxy of a hundred billion stars it's a target-rich environment. Telescopes extend that reach to galaxies so far away that the numbers start to lose meaning. The Hubble telescope captured the image above, a supernova observed in 1994,...
The Dragonfish is likely the largest such nebula in the Milky Way, making it easily visible even from other galaxies, yet it’s entirely invisible to our optical telescopes 龙鱼星云可能是银河系中最大的此类星云,即使从其他星系也能轻易观测到,但在光学显微镜下却完全不可见。
We could see that there are multiple galaxies beyond it… and all these galaxies are moving away from one another. So multiple galaxies… moving away from each other… led to the theory… MALE STUDENT:The big bang theory? MALE PROFESSOR:Exactly. And that theory, that 15 billion years ago ...

Hawking stars could be one way to find them. “Even though the Sun is used an exercise, there are good reasons to think that Hawking stars would be common in globular clusters and ultra-faint dwarf galaxies,” points out Professor Matt Caplan at Illinois State University, co-author of the...
What is a supernova made of? Where and how do stars form? What is the cycle of the making of a star? What are galaxies made of? What is a protostar made of? What kind of star is Procyon? What are planetary nebula made of? What is the Earth made of? What is Betelgeuse made of...
