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 […]

The reason why is simple, and should apply to every solar system like our own. On January 3rd, 2019, Earth reached the point in its orbit where it’s at its closest […]
What took hundreds of millions of years to create is being wasted on… party balloons? There’s a natural resource found beneath Earth’s surface that’s been building up for hundreds of […]
The Solar System’s outermost, undisputed planet wasn’t discovered until the 19th century. Here’s how you can easily find it yourself this December. There’s no greater scientific thrill than discovering something […]
Despite what you may have heard, they don’t suck anything in at all. Black holes are some of the strangest, most wondrous objects in all the Universe. With huge amounts of […]
Scientists have been probing our solar system for extraterrestrial life.
A case for looking beyond the planetary scientist’s (or even the astronomer’s) definition. Ever since 2006, when the International Astronomical Union (IAU) officially defined the term planet — introducing the term ‘dwarf […]
Was it a real thing? And the Wise Men? Or are they just myths?
If particles weren’t also waves, the Sun would never achieve nuclear fusion. Without quantum mechanics, life on Earth would never have come to exist. The greatest source of newly-produced energy in […]
It may have been captured by Neptune since it formed, but Triton remains king of the Kuiper belt. Our Solar System is arguably the most well-studied corner of the Universe, with […]
Researchers discover extraterrestrial origins of a chemical essential for human DNA and other cell processes.
If we restrict ourselves to looking for extraterrestrial life on Earth-like worlds, we might miss it entirely. When we think about life out there in the Universe, far beyond the […]
Christmas has many pagan and secular traditions that early Christians incorporated into this new holiday.
The Soviet Union’s space program was years ahead of the USA’s. So how did they lose the space race? Here in the United States and all across the world, humanity is […]
Stars don’t stay the same throughout their life, and the Sun is no exception. Here’s what’s going on. Here on Earth, the ingredients for life to survive, thrive, evolve, and sustain […]
When the Universe gives us clues, we ignore them at our own peril. When you approach the world scientifically, you seek to gain knowledge about how it works by asking it […]
Weather isn’t climate. The President isn’t a scientist. And physics is still real. The country is freezing in an unprecedented fashion, and global warming is to blame. Sound crazy? The cold […]
Finding the ingredients for life is a very different prospect than finding the products of life. Perhaps the greatest quest in science today is to find life that originated beyond Earth. […]
The coming few years should really tell us a lot more about them.
The evidence of water vapor plumes on Europa is enough for NASA to plan a probe that will take samples in 5 to 10 years.
The ancients had a cornucopia of holidays and festivities.
This is what we’ve learned from first object ever discovered to enter our Solar System from interstellar space. Billions of years ago, our Solar System was an extraordinarily different place […]
On January 20/21, half of Earth will experience a total lunar eclipse. For the first time in 19 years, this includes all of North and South America. When the Sun, Earth, […]
Walking all over the English countryside picking up trash, the genitalia of the spotted hyena, and many other subjects comical and deadly serious.
In order to reap the greatest rewards, we have to think big and invest big. One of these four missions will deliver like never before. When it comes to exploring the […]
If you want to go where no one has gone before, you have to make the investment. Here’s what last week’s launch means. If you want to send humans to Mars, […]
All the planets, asteroids, and Kuiper belt objects out there all point to the same conclusion: it’s giant impacts or no moons at all. Out of all the rocky planets […]
Some of the meteorites that strike our planet originate from our red neighbor, Mars. Here’s how we know. As the planets orbit the Sun, well-separated from one another, we tend to […]
The story of John Couch Adams, “the man who failed to discover Neptune,” and his cosmic redemption. Perhaps its human nature to want to only think positive thoughts about our […]
