We’re living longer than ever, but few of us will save enough to afford this historical boon.
Some pesticides are about as toxic as table salt.
Is there life beyond Earth, even in our Solar System? This mission might be humanity’s best hope of finding it. The biggest question facing humanity might be, “Does life exists beyond […]
The closest star to our own doesn’t just host one rocky planet, but a second, larger ‘super-Earth’ much farther out. Of all the stars in the Universe, the closest one to […]
While the world considers future trips to Mars, two astrophysicists make a case for exploring asteroids.
LIGO just announced the second neutron star-neutron star merger ever seen in gravitational waves. It doesn’t match the first. On August 17, 2017, an event occurred that forever changed how we […]
NASA JPL takes a first step toward a GPS for space.
If you’re wondering whether the blast wave or the radiation would kill us first, you’re asking the wrong question. As far as raw explosive power goes, no other cataclysm in […]
Not only can’t astronomers and planetary scientists agree, but the IAU made it worse for everyone. If you were alive in 2006, you likely remember a momentous event in astronomy: […]
Our Universe cannot be described by normal matter alone. Vera Rubin’s work led the way. Ask an astrophysicist what our Universe is made of, and you’ll likely receive a shocking surprise. […]
A loophole signed into law during the Bush administration has been fiendishly tough to close.
Only 8 worlds make the astronomical cut as planets. Here are the 10 fascinating bodies that didn’t make it. Astronomically, bodies within the Solar System must achieve three criteria in order […]
There are real problems that our society faces, and only through expert-level knowledge can we solve them. All across the country, you can see how the seeds of it develop from […]
Two of our biggest science-fiction dreams might not remain fiction for much longer. Here’s how 21st-century science could make it real. For as long as human beings have looked up at […]
And one of our planets has the orbiting moons to prove it. Despite the dangers posed to planet Earth by a comet or asteroid strike, our Solar System is actually an […]
Here are 7 often-overlooked World Heritage Sites, each with its own history.
If they saw us as we were before the recent industrial revolution, would there be any reason to particularly care about us? All across the Universe, trillions of galaxies can be […]
In all the Universe, there’s only one Earth. But can we find the other worlds that are like ours? Even though the ingredients for life have been confirmed to be practically […]
If you understand gravity well enough, you might not even need a telescope to revolutionize astronomy. In science, advances arise at the intersection of theory and real-world observation. One of […]
Doomsday prophesies have never once come to pass, but they’ve never had science on their side like this before. Every year, the Earth completes an orbital revolution around the Sun, returning […]
There’s a million things we haven’t done. But just you wait. The Universe as we know it began some 13.8 billion years ago with the onset of the hot Big Bang. […]
Beyond the oceans boiling and the death of our Sun, Earth’s ultimate fate won’t be determined until far in the distant future. It took the Universe 13.8 billion years to create […]
Tesla CEO Elon Musk shocked the markets on Tuesday with a series of tweets outlining the mercurial entrepreneur’s desire to take the company private.
After Kepler but before James Webb, TESS is preparing astronomers for the coming exoplanet revolution. There are always new discoveries and achievements occurring in science, and certain fields have experienced […]
Future or extraterrestrial civilizations could create megastructures the size of a solar system.
The hallmark of a good scientist is changing your mind when new evidence arises. Here’s what that looks like. Science, like many things in life, is always a work-in-progress. While a […]
Mars will never look as big as the full Moon. But it isn’t even the biggest planet. From humanity’s perspective, the Sun and Moon always dominate Earth’s skies. The Moon and […]
Beefless meat enters the mainstream.
A star orbiting past our galaxy’s supermassive black hole offered a chance to test relativity as never before. The supermassive black hole at the center of the Milky Way is the […]
