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. […]
If there are cracks in Einstein’s theory, this is how to find them. Is Einstein’s most powerful theory, General Relativity, always correct? Or will there come a point where it breaks […]
The view from beyond Pluto is far enough from Earth that we can see the stars shift. NASA’s New Horizons, humanity’s first spacecraft to encounter Pluto, is more than 4.3 billion […]
A single lifetime is more than enough to take you to the limits of the Universe. Right now, there are only three things limiting how far our spacecrafts can take […]
The drive would provide enough thrust for a spacecraft to travel near the speed of light using only electricity, says physicist Jim Woodward.
It comes from a supernova seen just 33 years ago, and it doesn’t pulse. 33 years ago, a supernova occurred just 168,000 light-years from Earth. This new image of the supernova […]

When the supernova occurs, a whole slew of signals will arrive at once. But there’s one hint that could successfully warn us in advance. As Betelgeuse continues to vary in brightness […]
Unlike most articles that are titled with a question, the answer isn’t automatically “no.” Announced on January 6, 2020, NASA’s TESS mission has just discovered its first Earth-sized, habitable zone […]
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 […]
Can neural networks help scientists discover laws about more complex phenomena, like quantum mechanics?
When it comes time for humanity to pick a new home, where will we go?
A binary white dwarf in a tight, super-fast rotation looks to be pumping out gravitational waves.
Princeton scientists find a new way to control nuclear fusion reactions.

A tourist generally has an eye for the things that have become almost invisible to the resident.
We just found the first one within 1,000 light-years of us. But there’s probably one much, much closer. For a long time, black holes were known to exist only in the […]
Amid such suffering, people need some joy.
You never know what you’re going to find when you look somewhere new for the first time. Approximately 4600 feet (1400 meters) underground, beneath the Italian mountain known as Gran Sasso, […]
The Moon, Venus, and Jupiter are the brightest night sky objects. On Thursday evening, November 28, they’ll all align, plus Saturn, too. As the planets orbit the Sun throughout the year, […]
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 […]
Our Universe is 13.8 billion years old, and our Sun formed about 2/3rds of the way through. Here’s what came before it. When it comes to the great cosmic question of […]
I’m not saying it’s not aliens, but it’s not aliens. When it comes to life in the Universe, we still have no definitive answer to the biggest question of all, “are […]
