Roger Babson wanted a “partial insulator, reflector, or absorber of gravity” — something, anything, that would stop or dampen it.
A unique combination of DNA and silica is the strongest known material for its density (but you’ll need a lot of it before you can build a suit from it).
With LEDs bringing brighter nighttime lighting than ever before, and thousands of new satellites polluting the skies, astronomy needs help.
Finding alien technology on the seafloor would be truly incredible. This extraordinary claim, however, is debunked by the actual evidence.
With JWST, Chandra, and gravitational lensing combined, evidence has emerged for the earliest black hole ever. And wow, is it a surprise!
Sometimes, going "deeper" doesn't reveal the answers you seek. By viewing more Universe with better precision, ESA's Euclid mission shines.
Freethink's weekly countdown of the biggest space news, featuring a stranded space factory, Jeff Bezos' new moon lander, and more.
The TRAPPIST-1 system is a treasure trove of possibilities and questions. Observations by JWST have just begun.
Out of the four rocky planets in our Solar System, only Earth presently has plate tectonics. But billions of years ago, Venus had them, too.
See the 3 biggest space stories from October 16-22, 2023.
Sophisticated rovers have found the conditions for Martian life, as well as the building blocks of life, but never life itself. AI can help.
Einstein's theory of general relativity introduced the concept of space having a shape. So, what is the shape of space?
"If we find just one other example of biology out there, then life is not an accident."
A true scientific view of if, where, and when extraterrestrial life exists is within our grasp thanks to biosignatures and technosignatures.
A woman’s name would undermine the credibility of the mission. Names of former Nazis, however, were no problem.
Back during the hot Big Bang, it wasn't just charged particles and photons that were created, but also neutrinos. Where are they now?
Considering the astronomical occupational risks, life insurance was prohibitively expensive for the first NASA astronauts.
The Universe, although violent, is filled with creation events following destructive ones. 1850 light-years away, both types are unfolding.
In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?
With such a vast Universe and raw ingredients that seem to be everywhere, could it really be possible that humanity is truly alone?
In the quest to measure how antimatter falls, the possibility that it fell "up" provided hope for warp drive. Here's how it all fell apart.
The laws of physics don't prefer matter over antimatter. So how can we be certain that distant stars & galaxies aren't made of antimatter?
Within the next few decades, we may well have hard evidence for the existence of alien life on worlds light-years distant from Earth.
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There's no evidence for oceans or life.
Chemical changes inside Mars' core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?
Finding a tiny planet around bright stars dozens or hundreds of light-years from Earth is extremely difficult.
An annular eclipse is coming to Earth on October 14, 2023. Six months later, a total solar eclipse is headed our way. Here's the reason why.
How does star-formation, occurring in small regions within galaxies, affect the entire host galaxy that contains it? JWST holds the answers.
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
In 1987, the closest supernova directly observed in nearly 400 years occurred. Will a pulsar arise from those ashes? JWST offers clues.
