There are ~400 billion stars in the Milky Way, and ~2 trillion galaxies in the visible Universe. But what if we aren't typical?

There's a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
The closest star system to Earth, just over 4 light-years away, has three stars and at least one Earth-sized planet. Is it time to go there?
Ketamine’s remarkable effect bolsters a new theory of mental illness.
There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here's what they really mean.
The study identified superhabitable planets outside of our solar system.
Almost everything we can observe and measure follows what's known as a normal distribution, or a Bell curve. There's a profound reason why.
By challenging your preconceptions, art offers a framework by which you can solve problems.
Virtual reality continues to blur the line between the physical and the digital, and it will change our lives forever.
The Big Bang was hot, dense, uniform, and filled with matter and energy. Before that? There was nothing. Here's how that's possible.
With radio and X-ray data combined, we’re understanding how energy flows like never before. When we look out at the Universe on the largest cosmic scales of all, gravity is the […]
Mixed messages and competing interests have left college students feeling lost and stressed.
Although equal parts Hollywood blockbuster and Putinist propaganda, "Trotsky" still manages to capture the good, the bad, and the ugly of Russia’s revolutionary past.
With a new telescope on the horizon, we reflect on the best pictures of space that came before.
A recent study illuminated surprising differences in how men and women seek help when struggling with relationships.
There are a few clues that the Universe isn't completely adding up. Even so, the standard model of cosmology holds up stronger than ever.
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
Some constants, like the speed of light, exist with no underlying explanation. How many "fundamental constants" does our Universe require?
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
The last naked-eye Milky Way supernova happened way back in 1604. The next one could be the key to solving the dark matter mystery.
The photometric filters for the Vera Rubin Observatory are complete and showcase why they are indispensable for astronomy.
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!
In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren't close to the same.
Political partisanship might be a treatable condition.
The last image puts it all in perspective. Compared to what we find in our Solar System, galaxies are truly enormous. The Sun may be 109 times the diameter of […]
We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]
Previously, only the brightest and most active galaxies could pierce the obscuring wall of cosmic dust. At last, normal galaxies break through.
Some neurology experiments — such as growing miniature human brains and reanimating the brains of dead pigs — are getting weird. It's time to discuss ethics.
America’s war in Southeast Asia is fading fast from memory. These maps offer a horrific reminder.
