The total solar eclipse of July 2, 2019, is the longest one we’ll have until 2027. And that’s not all. On July 2, 2019, the new Moon will pass between Earth […]

Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
It’s the largest, most massive planet in the Solar System. But what’s the real story behind all the impacts on Jupiter? One of the most terrifying prospects here on Earth is […]
A 1060-hour amateur exposure of a nearby galaxy does what even Hubble couldn’t do. The Universe is full of astronomical wonders, but it’s up to humanity to observe and analyze them. […]
From galaxies with no dark matter to ones with hundreds of times more dark matter than normal, our Universe needs it more than ever. One of the most mysterious substances in […]
The world’s greatest observatory can go no further with its current instrument set. The Hubble Space Telescope has provided humanity with our deepest views of the Universe ever. It has […]
Despite the claims of one of Earth’s newest Nobel Laureates, the data doesn’t lie. One of the greatest scientific successes of the past century was the theory of the hot Big […]
The light we observe isn’t the same as the light that gets emitted. Here’s what causes it. The light you see, when you look out at the stars and galaxies that […]
If we could see in three dimensions instead of two, we’d never have thought otherwise. Perhaps the most famous sight of a dying star is the Ring Nebula, discovered in […]
Within the next billion years, the Magellanic Clouds might merge with our galaxy. But the new stars are already here. Within the Milky Way, there are only a few instances of […]
What makes Uranus and Neptune-like worlds so fascinating? If you only knew. What do we really know, and what mysteries are left to solve, about the outer worlds of our Solar […]
A new paper claims that scientists might be wildly mistaken about the density — and therefore, the shape — of our universe.
Observations have been ruined; scientific satellites with the right-of-way have had to alter course. Here’s a how-to guide to doing better. In any field of business or industry, the prevailing rule […]
The first image of an Event Horizon is here. Here’s what it means. Variety isn’t just the spice of life, but a natural consequence of living in our Universe. Gravitation, obeying […]
Some have suggested that there is no hidden giant out there.
And what do we still have left to learn? The original idea of a black hole goes all the way back to 1783, when Cambridge scientist John Michell recognized that a […]
It wasn’t the birth of space and time. But it was truly essential to our cosmic story. For more than 50 years, we’ve had definitive scientific evidence that our Universe, as […]
A star orbiting past our galaxy’s supermassive black hole offered a chance to test relativity as never before. The supermassive black hole at the center of the Milky Way is the […]
There was less than a 2 second delay between gravitational waves and light, but that’s incredibly meaningful. There’s an important rule in relativity that — as far as we know — all objects must […]
Remember the announcement of a galaxy with no dark matter? It’s just been re-examined, with astounding results. In theory, all galaxies should contain copious amounts of dark matter, with one […]
The object, originally dubbed “Ultima Thule,” was renamed to “Arrokoth” due to the connection between the word “Thule” and the Nazis.
It likely isn’t the rare occurrence we once thought it was. In our Solar System, there’s one overwhelming source of mass that all the planets orbit around: our Sun. Each planet […]
Light cannot escape from a black hole, no matter what. But when two black holes merge? They just might. On September 14, 2015, history was made as the NSF’s twin LIGO […]
CERN’s bold new proposal has physicists confronting the biggest question of all: is building a new collider worth it? If you want to discover anything novel about the natural, physical […]
New research based on observational data from the Spitzer telescope provides clues as to how the universe first emerged from its dark age.
What should a black hole look like? Our theoretical predictions are about to meet our first observations. In science, there’s no moment more exciting than when you get to confront […]
When we send messages to the stars, just what are we getting ourselves into?
Everything is being driven apart. But there’s hope of reaching what’s currently so far away. For the first 7.8 billion years, the Universe unfolded exactly as scientists would have expected in […]
The massive Starlink satellite network from SpaceX is causing worries.
We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]
