The ‘final parsec problem’ is still a mystery for astronomers. When it comes to black holes in the Universe, we know there are at least two major types. There are […]
Are the stellar remnants in our cosmic backyard actually our parents and grandparents?
Hubble’s still going strong after 31+ years. James Webb will never make it that long. Every decision that’s made — in both astronomy and in life — comes with its own set of pros and […]
The quick test would be a breakthrough in cancer treatment.
The most massive nearby stars could be the seeds our supermassive black holes need. The problem with the Universe, as we see it today, is that we only get a snapshot […]
Dark matter must gravitate, so why couldn’t the graviton solve it? One of the most puzzling observations about the Universe is that there isn’t enough matter — at least, matter that we know […]
Binary pulsars are doing what no other measurement has done: measure our galactic acceleration directly. Even though the majority of the matter that makes up our Universe may be completely […]
Young galaxies are bright and blue; old galaxies are red and dead. So how did this old, red galaxy form so early? The observable Universe contains two trillion distinct galaxies, but […]
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 […]
It isn't surprising, but what's behind the straight-white-male hegemony?
All the things that surround us and make us up weren’t always here. But where did it all come from? The Universe, as we see it today, sure is full of […]
Why the effects of aging are detrimental to being the U.S. president.
Over the past 30 years, we’ve revolutionized what we know about the Universe. But we couldn’t have done it without these lessons. On April 24, 1990, the Hubble Space Telescope rocketed […]
The first list of antidepressant food scores restructures the "standard" American diet.
Stronger than the LHC and faster than anything except light, the world’s cleverest particle detector sees the particles we could never create on Earth. It might be true that there’s an […]
All supernovae are not created equal. After a 14 year investigation, the brightest ones have a surprising explanation. In 2006, astronomers witnessed a supernova that defied conventional explanation. Typically, supernovae […]
How do we see extremely short-lived stars in places that haven’t experienced star-formation in over 10 billion years? The most fundamental truth about stars is that when they run out of […]
After 13.8 billion years, there’s still a whole lot that’s changing as time goes on. With each new year that comes upon us, there are a slew of new events awaiting […]
This parody documentary skewers both the skeptic and the superstitious, and accurately shows what issues skeptics face.
Helium and carbon are made copiously in the interiors of stars. But the in-between elements? They’re rarities everywhere. If you were to take every element in the periodic table and […]
Some galaxies might not have any dark matter. Here’s why you should care. There are two assumptions that everyone makes about the Universe for extremely good reasons, but they might not […]
Galaxies are found uniformly everywhere in the Universe, except in the Milky Way’s plane. Here’s why. From the time of their very first discovery, the Universe’s grand spirals have puzzled astronomers. […]
Forget the speed of light or the electron’s charge. This is the physical constant that really matters. Why is our Universe the way it is, and not some other way? There […]
The Universe is filled with something, as opposed to nothing, and scientists don’t understand it. When we look around at the Universe: at the planets and stars, at the galaxies […]
