When people pick the greatest scientist of all-time, Newton and Einstein always come up. Perhaps they should name Johannes Kepler, instead.

Puerto Rico’s iconic telescope facilitated important scientific discoveries while inspiring young scientists and the public imagination.
If you think you know how an astronomical nova works, buckle up. You’re in for a ride like you never expected.
Want some crazy space phenomena? You don’t have to leave the neighborhood for it.
At its biggest for the next 15 years, it’s still much smaller than the Moon. On October 6, 2020, Mars makes its closest approach to Earth until 2035. Earth orbits in […]
From Ramses II to Alexander the Great, these leaders helped shaped the world we know today.
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
If you want flexibility, transparency, and decent health policies, it seems like working in tech pays off.
Don’t wait until Christmas to gift a telescope this year. All throughout the year, two bright lights have stood out in the post-sunset skies. Earlier this year, on March 31, 2020, […]
If you had a clear western horizon, you had your shot at this view! On September 9, 2021, the Moon and Venus nearly overlapped. A simulated view of the post-sunset skies […]
The past ~4 billion years have been an incredibly successful, unbroken run for life on Earth. The future won’t be nearly so bright.
At four million solar masses, the Milky Way’s supermassive black hole is quite small for a galaxy its size. Did we lose the original?
You might be inclined to modify gravity instead, but those ideas have grossly unequal evidence supporting them. What is it, exactly, that you’re supposed to do when the predictions of […]
A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.
The dream of zero resistance is closer than you may think. One of the biggest physical problems in modern society is resistance. Not political or social resistance, mind you, but electrical […]
Think there are habitable super-Earths out there? Think again. Here in our Solar System, we have two very distinct types of planets: small, terrestrial, rocky worlds, with thin (or no) atmospheres […]
New research explains why the Moon’s crust is magnetized by debunking one long-standing theory.
We’re not made out of the densest elements, but we’re the densest planet nonetheless. Here’s why. Of all the planets, dwarf planets, moons, asteroids and more in the Solar System, only […]
In 1990, we only knew of the planets in our own Solar System. Today, the exoplanet count is more than 5000. Here’s what we’ve learned.
It rotates on its axis, revolves around the Sun, moves throughout the Milky Way, and gets carried by our galaxy all throughout space.
How two seemingly distinct exoplanet systems turned out to be related. Practically every star in the Milky Way has a similar origin story. At some point in the past, a molecular […]
Planets are either rocky, like Earth, or gas-rich, like Neptune, with no in-between. What are the different types of planets that exist in the Universe? If all you could see […]
Ingenuity is remarkable. But these 5 exploration ideas are revolutionary. Telescopes are our initial tools for revealing and studying foreign worlds. Hubble images of Mars, particularly around the regions with […]
Science doesn’t exist in a cultural and existential vacuum and its teaching shouldn’t either.
On May 9, 2016, the prior transit of Mercury occurred, and was photographed many times on a practically continuous basis by NASA’s Solar Dynamics Observatory. Transits of Mercury are rare, […]
The surface and atmosphere is colored by ferric oxides. Beneath a very thin layer, mere millimeters deep in places, it’s not red anymore.
After a wait of 397 years in orbit, we’re finally getting a truly ‘Great’ Conjunction. Recently, December 21, 2020, Jupiter and Saturn finally met. Looking towards the southwest skies from […]
The solar system has some strange stuff in it. Learning how it ended up that way can tell us where we’re going.
Jonathan Berman wants us to have better dialogues.
Conjunctions this close are rare, but give humanity an opportunity to view our Solar System’s faintest planet. With eight planets orbiting our Sun, any two will eventually appear close together from […]
