Mathematically, it is a monster, but we can understand it in plain English.
From corrupt czars to bloodthirsty Bolsheviks, Russia has had no shortage of bad leaders. But just how evil were they really?
Every power source involves trade-offs. Given the challenges of increasing demand and climate change, what is the future of energy?
Solar geoengineering ideas could weaken storms in both hemispheres, scientists find.
How many potentially habitable planets are there? We sincerely don’t know. One of the most compelling scientific goals humanity has set for itself is to find extraterrestrial life: biological activity originating […]
A new study sheds light on the final supernovae of the Universe.
A famous thought experiment from the 1970s is more relevant today than ever before.
Named M51-ULS-1b, it’s certainly a curious astronomical event. But the evidence is far too weak to conclude “planet.”
When we look at the night sky, we may see junk instead of stars.
If you want to find life in the Universe, this is how you do it. When it comes to uncovering the ultimate truths about reality, we can only reap what we […]
A unique exoplanet without clouds or haze was found by astrophysicists from Harvard and Smithsonian.
There are three factors all competing to determine the fate of the Earth, and the one that’s winning now won’t win in the end. If you could measure the average distance […]
Using modern tools, a team of astronomers uses celestial sleuthing to figure out when Vermeer painted his masterpiece “View of Delft.”
When we look out at the Universe, even with Hubble, we’re only seeing the closest, biggest, brightest galaxies. Here’s where the rest are.
The Source Family, a radical 1970s utopian commune, still impacts what we eat today.
When one group says “A” and another group says “B,” consider that everyone might be wrong. One of the biggest enemies of scientific truth is the setup of a false dichotomy. […]
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
A supernova exploded near Earth about 2.5 million years ago, possibly causing an extinction event.
At four million solar masses, the Milky Way’s supermassive black hole is quite small for a galaxy its size. Did we lose the original?
The center of our Sun tops out at 15 million K, but nuclear bombs can get nearly 20 times hotter. Here’s how. In terms of raw energy output, nothing on our […]
For the first time, it was discovered that nonphotosynthetic bacteria have a circadian clock.
An unprecedented number of new satellites threatens the night sky as we know it. Will we act in time to save it?
The bizarre discovery could pave the way for advances in regenerative medicine for humans.
Take a journey through the maze of interpretations of one of the most famous paintings in history.
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 […]
As long as it remains operational, we’ll have a chance to conduct groundbreaking science with it. In the history of spaceflight, only five spacecraft ever launched by humanity possess enough energy […]
Probably not. Even though we’re still investigating the origin of life, the evidence suggests that cells came much later.
What was the universe like one-trillionth of a second after the Big Bang? Science has an answer.
Think they all burn through their fuel, die, and leave white dwarfs, neutron stars, or black holes behind? Think again. The day will come when our Sun, like most stars, can […]
