Both made monumental contributions that were far ahead of their time. It’s hard to believe, but the idea that the Universe was dominated not by normal matter but rather by dark […]
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
We’ve already observed three cases where it’s happened. When you look at an object in space, it’s pretty easy to tell if it’s a star or a planet. Stars are […]
The raw ingredients just weren’t there. Thankfully, their predecessors were. Here on Earth, our planet practically overflows with life. After more than 4 billion years, life has spread to practically […]
The scientists, not the fossil fuel industry, were right all along. Back in 1990, the world’s top climate scientists convened to put together a report on the state of Earth’s climate. […]
And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]
It peaks the nights of August 11–13, but it’s no longer the year’s most reliable meteor shower. Every year, beginning in mid-July, planet Earth commences passing through an enormous debris […]
We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]
Most of us will never run a 4 minute mile. But on a bicycle, almost anyone can do it. As human beings, we often take for granted how our bodies work. […]
Despite the recent headlines, it’s an extraordinarily unlikely proposition. Have you ever wondered, if it were possible to travel through space straight ahead as quickly as you could imagine, if […]
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 […]
Ignoring a scientific truth doesn’t change it, even when the consequences are deadly. “If all your friends jumped off a bridge, would you do it, too?” Many of us, as children, […]
And why, even at its faintest, it always outshines every other star and planet. If you’ve been looking to the west after sunset recently, you may have noticed that there’s one […]
The contact binary system KIC 9832227 is worth another look. Astronomers have seen some incredible occurrences across space and time. The nova of the star GK Persei, shown here in an […]
Yes, the Big Bang is real, but what about what came before? If you ask anyone about the origin of some phenomenon that we’ve observed, they’ll usually default to the same […]
When you view your right hand in a mirror, it appears as a left hand. Writing is reversed, as is the direction of any spinning object: clockwise becomes counterclockwise and […]
Metal really does sometimes stick to some people’s skin. Here’s the science of why. Every once in a while, a claim comes along that wildly challenges the mainstream scientific narrative. These […]
How slight differences could have forever changed our cosmic history. 13.8 billion years ago, what we know today as our Universe began with the hot Big Bang. Filled with matter, antimatter […]
Filaments, hundreds of millions of light-years long, were just caught spinning. In our own cosmic backyard, everything we see spins, rotates, and revolves in some fashion or other. Our planet […]
The only doubts are completely unreasonable. Where did the virus that causes COVID-19, SARS-CoV-2, come from? Over the past few weeks, there’s been a tremendous push — largely among politicians but also […]
Despite the enormous flood of recent reports, there’s no good evidence for a lab leak. At the very end of 2019, a new disease began to emerge in humans: COVID-19. Originally […]
The sacrifices of early astronauts paved the way for Apollo’s successes, and so much more. In all of history, only 24 humans have ever escaped Earth’s gravity. The very first launch […]
Our galaxy not only isn’t stationary, but different parts are accelerating at different rates. When we think about the Universe as a whole, the accelerations that objects experience from our […]
And a combination of all three might take us farther than ever. If you want to see the farthest objects in the Universe, you have to know not only where to […]
‘Fast Optical Bursts’ will confound ground-based astronomy. As of 2021, planet Earth is currently experiencing the least pristine night sky in recorded history. Prior to the development of artificial lighting, […]
Has all this happened before, and will all this happen once again? There are only a few questions, when we ask them, that force us to reckon with the fundamental nature […]
It occurred naturally, and scientists know this for certain. Starting in late 2019, a novel strain of coronavirus, SARS-CoV-2, began infecting human beings for the very first time. Discovered in samples […]
Even the ones hunting for aliens aren’t excited. Here’s the reason why. In this world, there are very few issues more polarizing than the notion of aliens. For as long as […]
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 […]
Even after our merger with Andromeda, we might retain our spiral shape for trillions of years. You probably don’t think about it very often, but the Milky Way galaxy won’t remain […]
