Colonizing the Red Planet isn’t a bad idea in theory. But . . .
USGS’s ‘Unified Geologic Map of the Moon’ is the definitive blueprint of the lunar surface.
When it comes time for humanity to pick a new home, where will we go?
One of the scientists with the Viking missions says yes.
Galaxies can have regions both hotter and colder than the background radiation of the Universe. When we talk about the depths of space, we get this picture in our heads […]
Until about a decade ago, only two habitable zone planets of any size were known to astronomers: Earth and Mars.
A NASA robot on Mars sends back unusual findings, including timed magnetic pulses.
What lies in store for humanity? Theoretical physicist Michio Kaku explains how different life will be for your descendants—and maybe your future self, if the timing works out.

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 […]
Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
The Red Planet, the God of War, and important life lessons for us all.
Can neural networks help scientists discover laws about more complex phenomena, like quantum mechanics?
Leap years will only get us through the next few thousand years before we have to fix it. With every year that passes, we assume that two separate things will both […]
A leading British space scientist thinks there is life under the ice sheets of Europa.
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
The planet that we are searching for is a little bit smaller and closer than we originally thought.

Planets are either rocky, like Earth, or gas-rich, like Neptune, with no in-between. What are the different types of planets that exist in the Universe? If all you could see […]
Since the late 1800s, what we know has advanced light years ahead.
The dream of an ‘Earth-like’ planet showcases our astrobiological ignorance. Over the past decade, our understanding of what planets exist around stars other than our own has exploded. The number […]
SpaceX’s momentous Crew Dragon launch is a sign of things to come for the space industry, and humanity’s future.
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, […]
It’s not volcanic activity, and it’s definitely not from a fire. Mars, our red planetary neighbor, is a vastly different world from Earth. Mars and Earth, to scale, shows how much […]
The water tower-shaped craft is an early prototype of Starship, which SpaceX hopes will someday send humans to Mars.
The new record-holder opens up a literal Universe full of possibilities. Someday, even our own Sun will eventually run out of hydrogen fuel in its core, bringing a tremendous set […]
Find a clear western horizon after sunset, and this ‘triple treat’ of a dance can be yours. Every once in a while, the night sky provides a spectacular feast for our […]
Catch Saturn at its biggest and brightest, and view its rings while you still can. Right now, in Earth’s skies, Saturn appears at its biggest and brightest. A view of tonight’s […]
The Apollo 11 astronaut was recently awarded the Stephen Hawking Medal for Lifetime Achievement.
Physicist Frank Wilczek proposes new methods of searching for extraterrestrial life.
If life exists on Mars, there’s a good chance it’s related to us, say researchers.
