The Universe isn’t just expanding, the expansion is also accelerating. If that’s true, how will the Milky Way and Andromeda eventually merge?

If light can’t be bent by electric or magnetic fields (and it can’t), then how do the Zeeman and Stark effects split atomic energy levels?
Giant particle accelerators aren’t a waste of money. They are essential for understanding the Universe.
Meet the power plant of the future.
The first supernova ever discovered through its X-rays has an enormously powerful engine at its core. It’s unlike anything ever seen.
Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.
Ground-based facilities enable the greatest scientific production in all of astronomy. The NSF needs to be ambitious, and it’s now or never.
Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.
An almost 40-year-old theory finally has ‘smoking gun’ evidence for it. During most of their lives, stars burn stably, changing imperceptibly. The rotten egg nebula, at lower right (and shown in […]
From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.
Singularities frustrate our understanding. But behind every singularity in physics hides a secret door to a new understanding of the world.
From exoplanets to supermassive black holes to the first stars and galaxies, Webb will show us the Universe as we’ve never seen it before.
More than two years after JWST began science operations, our Universe now looks very different. Here are its biggest science contributions.
There are over 100 known elements in the periodic table. These 8 ways of making them account for every one.
A study says nature’s candy can be a valuable supplement to sunblock.
The thrills and horrors of strange heavenly bodies condensed into one attractive snapshot.
“Carpe diem” was only one part of Horace’s poem Odes 1.11.
Gravitation, all on its own, can reveal what’s present in the cosmos like nothing else.
The human brain is only the latest chapter in the ancient story of thinking on Earth.
From the present day all the way to less than 400 million years after the Big Bang, we’re seeing how the Universe grew up like never before.
We should all pause to appreciate the awe-inspiring beauty of the Universe.
JWST has brought us more distant views of the early Universe than ever before. Is the Big Bang, and all of modern cosmology, in trouble?
The acceptance of death is deeply embedded in our culture; it’s time to overthrow that idea.
This representation of the Bamum kingdom is a rare example of early 20th-century indigenous African cartography.
What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
It doesn’t propagate at infinite speeds, and that’s a problem for Newton. When you look at the Sun, the light you’re seeing isn’t the light that’s being emitted right now. Instead, […]
We’ll never be able to extract any information about what’s inside a black hole’s event horizon. Here’s why a singularity is inevitable.
Mammals have a history stretching back 325 million years. To study that ancient history is to know our own origins.
We confidently state that the Universe is known to be 13.8 billion years old, with an uncertainty of just 1%. Here’s how we know.
