A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]

Congratulations to Penrose, Ghez and Genzel, and to black hole enthusiasts everywhere. On October 6, 2020, the Nobel Prize in Physics was awarded towards research in black holes. 50% of […]
A new study shows white dwarf stars create an essential component of life.
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 […]
According to international law, the seabed belongs to everyone.
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, […]
Is focusing solely on body mass index the best way for doctor to frame obesity?
New research sees dogs checking a North-South axis on their way home.
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 […]
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. […]
Map shows oldest buildings for each U.S. state – but also hints at what’s missing.
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 […]
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 […]
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 […]
What qualifies someone for the top position in American government?
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
We put presidents on our money, but isn’t there more to life than politics?
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 […]
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 […]
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 […]
Dark matter is perhaps the most mysterious substance in the Universe. What exactly it is, however, still eludes us. Dark matter is one of the most mysterious and yet most ubiquitous […]
From talking about Schrödinger’s cat to nuking the South Pole, this decades-old interview shows why Kaku was born to be a science educator.
