Ultraviolet LED lights could soon be used to help disinfect air and surfaces in buildings, planes, subways and other spaces.
With the right material at the right temperature and a magnetic track, physics really does allow perpetual motion without energy loss.
Is science absolute? Its truths and discoveries guide us toward the nature of reality, but we must always remain open-minded to revisions.
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn’t instant.
In 2006, Pluto was demoted in a very controversial decision. Unless you ignore nearly all of planetary science, it’ll never be one again.
The largest moon in our Solar System, often overlooked, is a water-rich world. Does that mean life? Here on Earth, life took hold very early on in our planet’s history, and […]
Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?
Whether they’re gas giants or rocky planets makes all the difference for life. Over the past 30 years, we went from not knowing if there were planets like ours around other […]
Water is vital for life. Luckily for spacefaring humans, the solar system is full of it.
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
The odds are slim, but the consequences would be literally world-ending. There really is a chance of a black hole devouring the Earth.
The most momentous and significant events in our lives are the ones we do not see coming. Life is defined by the unforeseen.
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant.
Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.
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 […]
Lots of people have seen lots of bizarre events and phenomena that defy our conventional experience. But is there a scientific explanation?
The most feared sexually transmitted disease (STD) of the last half-millennium was usually named after foreigners, often the French.
Binary black holes eventually inspiral and merge. That’s why the OJ 287 system is destined for the most energetic event in history.
A Mercury-bound spacecraft’s noisy flyby of our home planet.
Earth is the Solar System’s only known inhabited planet. Could Venus, if its phosphine signal is real, be our second world with life?
The idea of “absolute time” was our default for millennia. But time is relative, as gravity and motion both cause time to dilate.
It’s the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!
The eastern inner core located beneath Indonesia’s Banda Sea is growing faster than the western side beneath Brazil.
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
Unless you have a critical mass of heavy elements when your star first forms, planets, including rocky ones, are practically impossible.
We’ve only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.
Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.
