Although human beings arrived on Earth just ~300,000 years ago, we've transformed the entire planet completely. Here's how we did it.

After 15 years of monitoring 68 objects known as millisecond pulsars, we've found the Universe's background gravitational wave signal!
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
At just 3 solar masses, it eliminates the “mass gap.” Searching for black holes is one of the most difficult astronomical games a scientist can play. Emitting no light of their […]
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 […]
After Kepler but before James Webb, TESS is preparing astronomers for the coming exoplanet revolution. There are always new discoveries and achievements occurring in science, and certain fields have experienced […]
The past 300,000 years occurs in the blink of a cosmic eye, but it’s meant everything to humanity. The history of humanity was anything but inevitable. Although the Universe created […]
We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]
Is Google's moral compass broken?
The most surefire, easily-seen signature of life on Earth might be a cosmic red herring around other worlds. In our quest for life beyond the Solar System, it makes sense to […]
If you can’t explain the astrophysical signal that you see and cry ‘dark matter,’ chances are you’re not thinking hard enough. Despite our knowledge of the laws of physics, and the […]
The most unusual star known has finally had its dimming scientifically explained. Here’s the unusual, dusty resolution. The science of planet-hunting has truly taken off in the 21st century, with […]
It’s discovered thousands. But how many more are out there? “How vast those Orbs must be, and how inconsiderable this Earth, the Theatre upon which all our mighty Designs, all our […]
The indirectly find was completely unexpected, and, if it holds up, could give the James Webb Space Telescope its first tantalizing target. In the quest to understand our Universe, and […]
There’s a point beyond which we cannot go, there are things beyond that we cannot know. But here’s what we expect. “The Edge… there is no honest way to explain it […]
The oddest star known in the galaxy is dimming again, and this time it might give up some of its secrets! “As far as I can tell, every telescope that can […]
Could there be a massive, giant planet beyond Neptune? Here’s what the science says… for now. “Finding out that something you have just discovered is considered all but impossible is one […]
But are any of these potentially Earth-like worlds actually inhabited? Here are the prospects. “It isn’t only the beauty of the night sky that thrills me. It’s the sense I […]
A live-blog event happened a week ago, but you can catch the entire thing anew here, right now! “We have never observed infinity in nature. Whenever you have infinities in […]
I’m not saying it isn’t aliens… but it’s not aliens. “Just to clarify, neither Jason or myself … are advocating that it is an alien megastructure, but we also can’t completely rule […]
The ‘compact galaxy groups’ of the Universe won’t be around for long! “They most likely form as subsystems within looser associations and evolve by gravitational processes. Strong galaxy interactions result and […]
When our imaginations run wild, it’s important to remember that’s our fault, not the data’s. “Otherwise we are trying to communicate with someone who doesn’t exist with a system which doesn’t […]
Rather than life arising on Earth, did it already exist in space prior to our planet’s formation? “When you arise in the morning, think of what a precious privilege it […]
And, at a fundamental level, it can never be one. “Even when Darwin’s teaching first made its appearance, it became clear at once that its scientific, materialist core, its teaching concerning […]
In principle, they could, of course. But around bizarre star KIC 8462852? Probably not. “The fancy that extraterrestrial life is by definition of a higher order than our own is […]
And here’s the reason why, despite all you may have heard. “Thou shalt not embarrass thyself and thy colleagues by claiming false planets.” –Bill Cochran Late last year, one of the […]
As we all still recover from the Paris attacks, remember the beauty and joy of one of the most forgotten French discoveries. “Truth is more valuable if it takes you […]
Which makes you wonder what other “candidate worlds” aren’t worlds after all. “These types of systems could be ubiquitous in the universe. This is a really exciting time for planet hunters.” […]
Supernova remnants return the insides of exploded stars back to the Universe, making things like us possible. “No matter how ‘normal’ people look, living ‘ordinary’ lives, everyone has a story […]
Wanting to believe in the impossible can be far worse than keeping an open mind. “No man is so foolish but he may sometimes give another good counsel, and no man […]
