How Vera Rubin changed the Universe. “Science progresses best when observations force us to alter our preconceptions.” –Vera Rubin Look out at the night sky, and what do you see? […]
Whether it’s “super” or not, you won’t want to miss this piece of the Universe. “From out there on the moon, international politics look so petty. You want to grab […]
You know how bright the full Moon is. Well, from the Moon, how would the ‘full Earth’ compare? “I put up my thumb and shut one eye, and my thumb blotted […]
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 […]
Where gravity comes from has been an utter mystery. String theory offers an explanation.
IFLS might be fun for the armchair enthusiast, but couldn’t you have at least consulted an expert? “You were always a good officer. Until you weren’t.”–Saru, from Star Trek: Discovery With […]
What if we build from the sky down? NYC architects release designs for a skyscraper that would hang from an asteroid and travel between hemispheres.
From a “faint smudge” to the most intricate objects in our galaxy, we’ve come an incredibly long way. “From our home on the Earth, we look out into the distances … to […]
Astronomers trace the origin of repeating radio bursts from deep space to a dwarf galaxy 3 billion light years away.
We should be exploring the oceans as seriously as we explore space.
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 […]
Science may be one of the most complex human endeavors, but the lessons it teaches can be applied far outside of science. “I much prefer the sharpest criticism of a single […]
If it’s the anti-version of normal matter, could it possibly fall “up”? This article was written by Sabine Hossenfelder of Backreaction. Sabine is a theoretical physicist specialized in quantum gravity and […]
The US Air Force’s Space Horizons Team wants to juice America’s space program. Here’s how.
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 […]
New research explains how to build different types of outposts in space.
You’ve never seen a rogue planet like this. “Other galaxies like Andromeda are shooting these ‘spitballs’ at us all the time.” –James Guillochon, coauthor on the new study Black holes don’t […]
Elon Musk announces that SpaceX will fly two private citizens on a mission around the moon in 2018.
If we left on New Years Day, how close could we get if we kept accelerating every second of every day? “The very closest stars would require many years to visit, […]
Everything in the Universe today was compressed into a tiny volume. But how small was it? “The creation of something new is not accomplished by the intellect but by the play […]
How humanity discovered where our elements come from. This article was written by physicist Paul Halpern of the University of the Sciences in Pennsylvania. Paul is author of the new book […]
If the impossible space engine works, could dark matter reconcile the laws of physics with these bizarre experimental results? “…axions are potentially detectable through their weak coupling to electromagnetism…” –Aaron […]
Thanksgiving may already be a week behind us, but there’s always something to be thankful for. “If a fellow isn’t thankful for what he’s got, he isn’t likely to be thankful […]
Risks abound for those plucky few willing to put their lives on the line to populate the Red Planet.
In the depths of intergalactic space, the Big Bang’s leftover glow is just 2.73 K. But this spot in our own galaxy is even colder. “If you want your boomerang to […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
And what it found was a world swimming, literally, with possibilities. Just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies. The misfit becomes the […]
US scientists fearing for Earth’s climate future begin testing solar geoengineering. The consequences may be terrifying — which is exactly why we need these small-scale experiments.
Gravity is the oldest fundamental force ever discovered. Might it not be fundamental after all? “The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic […]
