Space is getting bigger, but atoms, humans, Earth and our Milky Way stay the same size. How is this possible? “The Universe is expanding the way your mind is expanding. […]

Because “Earth-like” doesn’t necessarily mean “like our Earth.” “I have lost tolerance for things without meaning. There is no time for them. Does that make sense?” –Sara Seager At the end […]
Astronomers find a galaxy made almost entirely of dark matter.
SETI is searching for the same signals humans were producing in the 1960s. Why wouldn’t aliens do better? “I know perfectly well that at this moment the whole universe is listening […]
LIGO’s world-changing announcement was the beginning. The best is what comes next. “It’s the first time the universe has spoken to us through gravitational waves, up to now we’ve been deaf […]
A shining bauble among a diffuse cloud of stellar debris has a tremendously interesting physics story behind it. “Truth is tough. It will not break, like a bubble, at a touch; […]
There’s useful science to be gotten out of it, but most science that mentions it is anything but. “There is a voice inside of youThat whispers all day long,‘I feel this […]
Rather than life arising on Earth, did it already exist in space prior to our planet’s formation? “When you arise in the morning, think of what a precious privilege it […]
The nearest exoplanet ever has been observed, but not yet seen. Is this what the ‘Earth Next Door’ looks like?
The press says yes. But what does the science say? “This isn’t my life anymore, Mulder. I’m done chasing monsters in the dark.” –Dana Scully, X-files Without a doubt, one […]
How the bulge, disk, and halo stars of Andromeda reveal lessons we cannot see about our own galaxy. “He who would search for pearls must dive below.” –John Dryden The Milky […]
Thanksgiving may already be a week behind us, but there’s always something to be thankful for. “If a fellow isn’t thankful for what he’s got, he isn’t likely to be thankful […]
Three simple questions; an amazing story that goes way beyond Einstein! “Each ray of light moves in the coordinate system ‘at rest’ with the definite, constant velocity V independent of […]
Each might be as heavy as an asteroid and as tiny as a decimal point.
That’s not how probability works. Or asteroids, for that matter. “Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, […]
Think we’d never do better from the ground than from space? This adaptive optics system is proving this wrong! “This event marks the culmination of many years of hard work on […]
The highest energy collisions go beyond any collider… and may hold a fantastic secret! This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity. […]
Albert Einstein was the first to discuss the fabric of space, and according to his theorems, the curvature of it. We have been discussing the possibility of gravitational waves ever since.

A “double burst” of star formation in a globular cluster may explain our galaxy’s mysterious center. “It matters not what someone is born, but what they grow to be.” –J.K. Rowling […]
Astrophysicists have been looking for worlds like Proxima b since the 19th century. At last, they’re found! This article is contributed by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
In 1994, Miguel Alcubierre showed how warp drive could be made real within General Relativity. What does that imply? “Its continuing mission: to explore strange new worlds, to seek out new […]
The way to greatness requires us to look forwards, not backwards. “Whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, […]
How they get so big so fast is a mystery. Could “direct collapse” be the solution we’re seeking? “For something to collapse, not all systems have to shut down. In most […]
https://players.brightcove.net/2097119709001/4kXWOFbfYx_default/index.html?videoId=5131037086001 It’s the 10th anniversary of dark matter’s most compelling proof. “It may be that ultimately the search for dark matter will turn out to be the most expensive and […]
Ultra-deep field? Move over; there’s a new deepest-view of all! “In other words, theory attempts to segregate the minimum number of possible worlds which must include the actual world we inhabit. […]
We’re looking back in time when we look across the light years, so what’s different between what we see and what’s really there? “I saw a star explode and send out […]
The Big Bang’s leftover glow tells us a lot more than just where we came from. “Cosmology is the study of the origin, evolution, and fate of objects in the observable […]
During a live audio conference, NASA announced the discovery of 1,284 confirmed exoplanets as part of a new method outlined in a recent study. This method may help cut down the busywork of finding habitable planets.
From “billions and billions” to more than two trillion, we still need dark matter as much as ever! “In order for the light to shine so brightly, the darkness must be […]
The detection of a second binary black hole merger officially begins the robust era of a new kind of astronomy. “It turned out that nature was very kind, and there […]
