The theory is accurate within at least one part in a quadrillion.

No matter what physical system we consider, nature always obeys the same fundamental laws. Must it be this way, and if so, why?

The James Webb Space Telescope viewed Neptune, our Solar System's final planet, for the first time. Here's what we saw, and what it means.

From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?

UAP are no laughing matter anymore.

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

Recent research suggests that Earth’s magnetic field bounced back just as complex life was starting to emerge on our planet.

Yes, NASA's Perseverance rover found organics on Mars. So did Curiosity. Unfortunately, that doesn't mean anything in the search for life.

An average undergraduate student in physics is better than the AI.

You would think that with all our technology, like the James Webb Space Telescope, we would know how big the Universe is. But we don't.

Since the time of Galileo, Saturn's rings have remained an unexplained mystery. A new idea may have finally solved the longstanding puzzle.

Black holes aren't just the densest masses in the Universe, but they also spin the fastest of all massive objects. Here's why it must be so.

On the morning of June 30, 1908, an explosion of more than 10 megatons occurred above the sparsely populated Siberian Taiga. What caused the so-called Tunguska event?

The first set of James Webb's images blew us all away. In just 2 mere months, it's seen highlights that no one could have predicted.

As recently as 1990, we didn't know of any planets beyond our Solar System. Today, with 5000+, we're deep into the weeds of how they form.

Following the advent of human space flight, NASA began naming missions after children of Zeus.

Each of us carries our own version of the Multiverse in our heads.

One book will gather all topics on the search for life in the Cosmos.

An astrophysicist explains these shortcuts through space-time.

No planet enters retrograde more frequently than Mercury, which does so 3-4 times each year. Here’s the scientific explanation for why.

Asteroid collisions aren't always bad.

Venus Life Finder could launch as early as 2023.

Spaceguard shows that we can manage risks to the extinction of humanity — if only we put our mind to it.

Remembering Frank Drake, who transformed the search for alien life & extraterrestrial intelligence into a full-fledged scientific endeavor.

Einstein's relativity teaches us that time isn't absolute, but passes relatively for everyone. So how do telescopes see back through time?

Oxygen isn't strictly necessary for combustion, but it is ideal. Any advanced (alien) civilization probably uses oxygen to burn things.

Planets can create nuclear power on their own, naturally, without any intelligence or technology. Earth already did: 1.7 billion years ago.

The last 70 years have taken us farther than the previous 70,000. But can we accomplish more than creating a record saying, "We were here?"

From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.

No. No no no. Just... no. The JWST has truly blown our scientific minds, but it's a pure crackpot idea that the Big Bang is now disproven.
