If you don’t have pristine, dark skies, you might never connect to the Universe. But there’s hope. “Before we devised artificial lights and atmospheric pollution and modern forms of nocturnal entertainment […]
The outer three can even be seen with a small, 1.5 meter telescope. This 2010 picture of three of the four known exoplanets orbiting HR 8799 represents the first time […]
If humans are going to explore the solar system, we need to figure out how to live in space. The best way to figure that out is on the Moon — and you can help. Here’s how.
Brown dwarfs are the ultimate failed stars, but they might not remain as failed forever. “[Brown dwarfs] appear to live a more exciting life than we presumed. They are too big […]
Sometimes, what nature gives you is even better than what you hoped for. “Science doesn’t always go forwards. It’s a bit like doing a Rubik’s cube. You sometimes have to make […]
The Earth is round, Kyrie Irving. But not every world needs to be. “‘I’ll follow him to the ends of the earth,’ she sobbed. Yes, darling. But the earth doesn’t have […]
If Scotty beams you up for a trip around the Sun, here’s how to handle it. “I really didn’t have to work, shall we say, with Star Trek. It was a […]
We claim it’s the leftover glow from the Big Bang, but where is this light actually coming from? “We are told to let our light shine, and if it does, we […]
One of inflation’s cofounders has turned his back on the idea. But practically no one else is following him. Is he right? This article was written by Sabine Hossenfelder. Sabine is […]
From a speculative story to solid science! “The new ALMA images show the disk in unprecedented detail, revealing a series of concentric dusty bright rings and dark gaps, including intriguing features […]
If black holes lose information in an event horizon, then do we have a paradox with our cosmic horizon? “The history of astronomy is a history of receding horizons.” –Edwin Hubble […]
We take for granted how much the Moon does for Earth, but not all of the changes would be bad. “If we get rid of the moon, women, those menstrual cycles […]
This was the first direct measurement of gravitational waves ever, as predicted by Einstein.
The greatest advances in human history have come from science and scientific knowledge. Don’t stop now. “Bad times have a scientific value. These are occasions a good learner would not miss.” […]
Space is getting bigger, but atoms, humans, Earth and our Milky Way stay the same size. How is this possible? “The Universe is expanding the way your mind is expanding. […]
As president, Donald Trump is uniquely positioned to bring America back to the Moon.
The first ultra-deep, ultra-wide field view of the Universe heralded what the 2010s would bring. “Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal […]
As if the north pole of Saturn weren’t weird enough already. “Cassini is different — it’s a mission of enormous scope and is being conducted in grand style. It is much more sophisticated […]
It might be the nearest supernova humanity will ever see. What will happen when it goes off? “Without these supernova explosions, there are no mist-covered swamps, computer chips, trilobites, Mozart or […]
Is gravitational repulsion a real thing? “For the first time, astronomers have outlined and named the network of galaxies that includes the Milky Way, adding a line to our cosmic address […]
Just because we know it’s real doesn’t mean it’s easy to create in a lab. “For me the best answer is not in words but in measurements.” –Elena Aprile Atoms, molecules, […]
Stephen Hawking has accepted an offer to go to space. He’s one of the world’s most famous scientists, who’s been paralyzed due to ALS for much of his life.
From a “watery past” to water today! “If you look at the field of robotics today, you can say robots have been in the deepest oceans, they’ve been to Mars, you […]
Before you even look through your telescope, you need to know where to begin. “If you can’t measure something, you can’t understand it. If you can’t understand it, you can’t control […]
Never heard of SKA, the square kilometer array? Once it starts taking data, you’ll never forget it. “Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for […]
Scientists are starting to run for office to bring evidence-based reasoning back to government.
Jupiter’s icy moon, Europa, may spout water vapor miles into space, says NASA, making it possible to better determine whether its vast underwater oceans support extraterrestrial life.
What caused the incredible eruption that Hubble caught on film? A predicted merger in 5 years might show us. “We have chased away the clouds, the sky is all ‘rose.’” –Francois […]
Our tiny Earth may have changed a lot, but the gradual changes of the Universe add up, too. “We are not the same persons this year as last; nor are those […]
