Puerto Rico's iconic telescope facilitated important scientific discoveries while inspiring young scientists and the public imagination.
Even with all the recent impacts we've seen, it might be more "foe" than "friend" to us.
“It doesn’t erase what happened to you. It just changes the impact it has on your life.”
For the cosmos, it’s all too easy being green. Stars come in a wide variety of colors, but never green. Stars form in a wide variety of sizes, colors and masses, […]
There are an estimated two trillion galaxies within the observable Universe. Most are already unreachable, and the situation only gets worse.
Every power source involves trade-offs. Given the challenges of increasing demand and climate change, what is the future of energy?
Scientists at the San Diego Zoo are on a mission to resurrect the extinct northern white rhino.
Forget these scientific myths to better understand your brain and yourself.
After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way's central black hole looks like.
Infrared, visible, and ultraviolet combine to show us Jupiter’s features as never before. The largest planet in our Solar System, Jupiter, is our own ‘failed star.’ The best evidence-based classification scheme […]
A new control system, demonstrated using MIT’s robotic mini cheetah, enables four-legged robots to jump across uneven terrain in real-time.
Archaeologists discover a cave painting of a wild pig that is now the world's oldest dated work of representational art.
Cryptocurrency “news” is dominated by enthusiasts and haters. Surely, an intellectual discussion can be had.
Previously, only the brightest and most active galaxies could pierce the obscuring wall of cosmic dust. At last, normal galaxies break through.
A few years ago, the first dark matter-free galaxies were announced, and then immediately disputed. Now, there are too many to ignore.
One image can give over 100 times the data we now get from Hubble. NASA’s Hubble Space Telescope, launched in 1990, revealed the previously unseen Universe. The most distant galaxy ever […]
The author of classics like "A Farewell to Arms" and "The Sun Also Rises" is known and loved for his simple yet effective writing style. Here’s how to imitate it.
The majority of the matter in our Universe isn't made of any of the particles in the Standard Model. Could the axion save the day?
Whatever’s lurking out there, it isn’t all, or even mostly, normal matter. When it comes to the Universe, it’s only natural to wonder what, exactly, it is that makes everything up. […]
If you think it’s just three quarks held together by gluons, you’ll want to read this. At a fundamental level, the Universe is composed of indivisible particles. From macroscopic scales down […]
Learning styles are supposed to help learners take ownership of their education, but research doesn’t back up this well-intentioned myth.
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 […]
Have any of the stars we can see burned themselves out completely? When we look out across the Universe, we’re also peering back in time. In the early 21st-century, we’ve […]
Remedies must honor the complex social dynamics of adolescence.
When you mix science with speculation, you get speculation. But the underlying science is still real. Whenever you hear the phrase, “it’s just a theory,” it should trigger alarm bells in […]
With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.
With 1550 distinct type Ia supernovae measured across ~10 billion years of cosmic time, the Pantheon+ data set reveals our Universe.
Are the stellar remnants in our cosmic backyard actually our parents and grandparents?
Yet, if they only obey the rules that we know, there’s no way to explain why. One of the greatest puzzles in all of physics is that the laws of nature — as […]
