A black hole punched a hole 15 Milky Ways across in a galaxy cluster’s gas, by far the largest ‘kaboom’ ever seen. The Universe, everywhere we look, is full of cataclysmic […]

There’s so much we don’t know about fast radio bursts and galactic halos. Combined, we get a unique window on the Universe. Deep in space, mysterious signals known as Fast […]
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
13.8 billion years isn’t close to enough time, but if we wait long enough, even our Sun will become one. The Big Bang happened approximately 13.8 billion years ago, and it […]
It’s a supergiant star in the final stage of its life, and it just dimmed by an enormous amount. What’s going on? When you take a look at the stars in […]
As Game of Thrones ends, a revealing resolution to its perplexing geography.
The origin of the 3rd element on the periodic table was one of the great cosmic mysteries. We just solved it. How did we form the elements that pervade the Universe […]
From anti-gravity pens to cool model kits, these space-themed gifts will make any star gazer very happy.
If this discovery came in a pre-LIGO era, maybe it would have been a surprise. But in 2019, there’s no mystery at all. Did you hear that astronomers had recently […]
How does one supernova get so bright, so energetic, and so massive? It’s a spectacular mystery to solve. On February 22, 2016, one of humanity’s automated sky-scanning telescopes — the Pan-STARRS Survey for […]
Gravity gets weaker as the distance squared. But gravitational waves only get weaker as the distance. Why? One of the things we often just accept about the world is that […]
For decades, one of the Big Bang’s greatest predictions was shrouded in doubt. The answer was always there on Channel 3. When it comes to the question of how our Universe […]
If we ruin the night sky too severely, ground-based astronomy could suffer tremendously. Here’s why space is no replacement. There is an existential threat to astronomy as we know it, […]
A lifelong fan on why she’s drawn to the magnificent gas giant.

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 […]
What happened 4.56 billion years ago is the most important part of the cosmic story ever to happen to us. If you were to look at our Universe at the time […]
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 […]
LIGO just announced the second neutron star-neutron star merger ever seen in gravitational waves. It doesn’t match the first. On August 17, 2017, an event occurred that forever changed how we […]
With a new data run coming in 2019 at unprecedented sensitivity, we might finally get our answers. Over the past three years, LIGO discovered ten independent instances of merging black holes […]
Our Universe is 13.8 billion years old, and our Sun formed about 2/3rds of the way through. Here’s what came before it. When it comes to the great cosmic question of […]
The answer is surprisingly simple, if cataclysmic.
And how cutting just $1 billion per year in funding from NASA’s budget would be a catastrophe for science. When you think of the great cosmic beyond and what we know […]
If they saw us as we were before the recent industrial revolution, would there be any reason to particularly care about us? All across the Universe, trillions of galaxies can be […]
The true course of progress is not only charted by great men and women, but also by ordinary people having conversations.
Trump is #45 but Pence is #48 – and other strange consequences of the curious office of vice president.
The hot Big Bang occurred 13.8 billion years ago, and there’s no other possible answer consistent with what we know today. Conceptually, it might seem like the simplest idea in existence […]
Maybe, but that probably doesn’t mean what you think it does. Of all the unsolved puzzles in the Universe, perhaps the most confounding is the dark matter problem. If we look […]
Vitamins do work — when eaten in whole foods, not pills.
A recent headline claimed they could. But if gamma-rays are just a form of light, don’t they have to travel at light-speed? There’s an ultimate speed limit in the Universe: […]
