NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.
Over the past 50 years, 27 leap seconds have been added to our time.
With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.
The Universe begins with negligible amounts of angular momentum, which is always conserved. So why do planets, stars, and galaxies all spin?
Venerated astrophysicist Carl Sagan entertained the possibility.
Before we discovered gravitational waves, multi-messenger astronomy got its start with light and particles arriving from the same event.
It's the very closest stars to us that hold the key to unlocking the possibilities for life in star systems all throughout the Universe.
This technological feat changes our cosmic history.
Sooner or later, Earth is going to be hit by a large enough space object to cause significant damage to humanity. Stopping them isn't easy.
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.
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.
"Spanish Stonehenge" contains 526 giant stones, three circular burial sites, a quarry, and four necropolises.
“The more we understand ourselves and the universe, the more magnificent it is.”
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.
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.
One book will gather all topics on the search for life in the Cosmos.
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.
Spaceguard shows that we can manage risks to the extinction of humanity — if only we put our mind to it.
The concept is so complex that scientists still argue whether it exists or if it is an illusion.

Remembering Frank Drake, who transformed the search for alien life & extraterrestrial intelligence into a full-fledged scientific endeavor.
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?"
If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
Unexpected images of galaxies from the James Webb Space Telescope do not disprove the Big Bang. There are other likelier explanations.
