In 2011, a bizarre, green object was discovered. At long last, we finally understand why. One of astronomy’s biggest surprises came in 2007, when a mysterious green object was found. […]

A few years ago, the first dark matter-free galaxies were announced, and then immediately disputed. Now, there are too many to ignore.
When you mix science with speculation, you get speculation. But the underlying science is still real. Whenever you hear the phrase, “it’s just a theory,” it should trigger alarm bells in […]
More energy means more potential for discovery, but we’re topped out. If your goal is to discover something completely novel, you have to look in a way that no one else […]
Are the stellar remnants in our cosmic backyard actually our parents and grandparents?
Every December, the Geminid meteor shower reaches its peak. Its 2021 show will be spectacular, but only if you do it right.
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 […]
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 […]
With 1550 distinct type Ia supernovae measured across ~10 billion years of cosmic time, the Pantheon+ data set reveals our Universe.
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 […]
A new study shows white dwarf stars create an essential component of life.
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 […]
