Both views are equally spectacular, but unequally informative. Every so often, a creative amateur project highlights our professional achievements. This mosaic shows the region between the constellations of Cygnus and […]
Find out the truth for yourself. If this past year has shown us anything, it’s how thoroughly we rely on high-quality expertise. As the COVID-19 pandemic swept the globe, it […]
The majority of the matter in our Universe isn’t made of any of the particles in the Standard Model. Could the axion save the day?
Is focusing solely on body mass index the best way for doctor to frame obesity?
According to international law, the seabed belongs to everyone.
It might not feel that way, but a 95% dark Universe really is the best game in town. No matter how much we might try and hide it, there’s an enormous […]
New research sees dogs checking a North-South axis on their way home.
Telescopes from the ground are bigger, but have to fight the atmosphere. Here’s how to win. In astronomy, seeing farther and fainter than ever before requires three simultaneous approaches. First light, […]
In order, they go: hydrogen, helium, oxygen, carbon, neon, nitrogen, magnesium, silicon, iron, sulfur. Here’s how we made them. Everything found on planet Earth is composed of the same ingredients: atoms. […]
The Sun produces a wide variety of particles and radiation throughout it, but all of its neutrinos are produced in the core: where nuclear reactions take place. The various reactions […]
Trump is #45 but Pence is #48 – and other strange consequences of the curious office of vice president.
I’m not saying it’s not aliens, but it’s not aliens. When it comes to life in the Universe, we still have no definitive answer to the biggest question of all, “are […]
If dark matter is fundamentally different from the normal matter we know, there should be a way to test it. Here are the results. Dark matter — despite the enormous indirect evidence for […]
Map shows oldest buildings for each U.S. state – but also hints at what’s missing.
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 […]
It’s massive, it’s transparent, and it’s ubiquitous. But so is our ignorance. When we look out at the Universe, we have two general ways to try and make sense of […]
The rings are raining down onto the planet, and disappearing surprisingly fast. 4.5 billion years ago, our Solar System first formed. Protoplanetary disks, which all solar systems are thought to […]
What qualifies someone for the top position in American government?
We put presidents on our money, but isn’t there more to life than politics?
If there are cracks in Einstein’s theory, this is how to find them. Is Einstein’s most powerful theory, General Relativity, always correct? Or will there come a point where it breaks […]
The Universe’s idea of a ‘typical star’ has changed dramatically over time. When you look out at the Universe today, you’re not seeing it exactly as it is at one particular […]
Think there are habitable super-Earths out there? Think again. Here in our Solar System, we have two very distinct types of planets: small, terrestrial, rocky worlds, with thin (or no) atmospheres […]
One look at the uncertainties and the assumptions changes the story tremendously. Is there intelligent life out there in the Milky Way beyond our own Solar System? If so, how […]
Learn how to get the best views no matter where you are. Every year, no matter what else is occurring on Earth or in the heavens, you can rely on two […]
A recent survey also found that political messaging from the pulpit increased the likelihood of believing presidents to be ordained by God.
One of NASA’s original great observatories, Spitzer showed us the infrared Universe as never before. On January 30, 2020, NASA’s Spitzer Space Telescope was retired after a 17 year mission. Prior […]
After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
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 […]
When you look at the Universe in an entirely new way, you sometimes find what you could never have anticipated. Almost exactly one year ago today, the Event Horizon Telescope […]
