SETI is searching for the same signals humans were producing in the 1960s. Why wouldn’t aliens do better? “I know perfectly well that at this moment the whole universe is listening […]

An astronaut looked out the window of the Cupola—an observation nook on the International Space Station (ISS)—and saw a crack in the glass. Imagine floating in space in a pressurized spacecraft and seeing a crack in the thing keeping you safe from the empty void outside.
From Space, in HD. “You cannot rob me of free nature’s grace,You cannot shut the windows of the skyThrough which Aurora shows her brightening face.” –James Thomson Ever since humanity first […]
There’s a big gap between Helium and Carbon. Come find out why! “And argon, krypton, neon, radon, xenon, zinc and rhodium,And chlorine, cobalt, carbon, copper, tungsten, tin and sodium.These are the […]
Paul Davies suggests we open our minds to where alien messages might be hiding, including in our own DNA.
No one is right 100% of the time. Even the greatest genius of all. “The only man who never makes a mistake is the man who never does anything.” –Theodore Roosevelt […]
The highest energy collisions go beyond any collider… and may hold a fantastic secret! This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity. […]
Could finding a planet capable of supporting humans already be within our reach? “The diversity of the phenomena of nature is so vast and the treasures hidden in the heavens so […]
We see them change in wavelength, energy and in their electric and magnetic fields over time. So how do they experience it? “Everyone has his dream; I would like to […]
All pointing toward the Standard Model plus General Relativity not being all there is. “The Universe is very, very big. It also loves a paradox. For example, it has some extremely […]
The gravitational waves were real. But earlier announcements that X-rays and gamma-rays were detected, too? Not so much. “What’s really exciting is what comes next. I think we’re opening a window […]
Sure, we move through it just like space, but it was the aftermath of Einstein that led to us truly understanding it. “It is old age, rather than death, that […]
How colliding galaxy clusters emit the most spectacular fireworks, if only you look beyond what your eyes can see! “Every single time you make a merger, somebody is losing his identity. […]
There’s a small rock orbiting our planet more distant than the Moon we know. Does that mean we have two Moons? “You can be the Moon and still be jealous of […]
Earth day may have been last week, but the lessons we learned about Earth from space are with us always. “We are not learning to view ourselves as an advanced, evolving […]
And if it is, what does that mean for dark energy, and our Universe’s fate? “Until the 1990s, there were few reliable observations about movement at the scale of the […]
A view that no one ever had — not even from space — until Astronaut Don Pettit changed everything with these stunning photographs. “This job is a great scientific adventure. But it’s also a […]
Now that LIGO’s found two pairs of merging black holes, what does the future hold? “We shall not cease from exploration, and the end of all our exploring will be to […]
The atmosphere is on the mend, according to an article published in Science. It took almost 30 years for the ban on ozone-depleting substances to work and scientists are saying the ozone could be completely healed by the middle of the century.
We’re looking back in time when we look across the light years, so what’s different between what we see and what’s really there? “I saw a star explode and send out […]
If we started all over again, could our Solar System’s second planet have been the inhabited one? “It was the Venus I had prayed to, it was my prayer, though […]
The massive black holes that formed LIGO’s first event were a surprise, and then a mystery. Here’s the long-awaited solution! “Black holes can bang against space-time as mallets on a […]
If you’ve ever wondered just why it has piqued the interest of so many, have a look inside. “I just think too many nice things have happened in string theory for […]
There is software that can track drones in open areas, but none that can do so in tight-knit, urban ones.
Neil deGrasse Tyson and others consider whether alien diseases have the potential to wipe out humanity and maybe already have in the past.
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 […]
They’re judged to be “standard candles” and the greatest cosmic distance indicators. What if they’re not so standard? “It’s everywhere, really. It’s between the galaxies. It is in this room. […]
If we look to the distant future, with unlimited technology, how far could we reach? “Even if I stumble on to the absolute truth of any aspect of the universe, I […]
Those white spots are still salt, but there’s so much more there! “Although impact processes dominate the surface geology on Ceres, we have identified specific color variations on the surface […]
Gamma rays from black holes? It’s an incredible idea… and it’s probably wrong. “That’s the next step: to simultaneously see [gravitational waves] with three, four or five interferometers, localize it quickly, […]
