Supermassive black holes are thought to grow slowly, as they pull in matter from around them over billions of years. But if that’s the case, how did they appear so early in the universe’s lifetime? Now, researchers have proposed a new origin story for … Continue reading Collapsing dark matter halos could seed supermassive black holes
Astronomers say they’ve closed the case on the mysterious and unprecedented dimming of the supergiant star Betelgeuse in 2019 and 2020. A new study says that the event was caused by a combination of a big dust cloud and a drop in temperature.Continue R… Continue reading Astronomers conclude Betelgeuse isn’t dying, it’s just dusty
Like most galaxies, the Milky Way is thought to host a supermassive black hole in its center – but perhaps its dark heart is made of different stuff. A new study proposes that it could instead be a dense core of dark matter, made up of hypothetical par… Continue reading Milky Way’s central black hole could be a ball of dark matter
The universe is expanding, and that expansion is accelerating. But what is causing that to happen? The leading hypothesis is a repellent force that astrophysicists refer to as “dark energy,” which pushes everything away from everything else. So how doe… Continue reading Dark energy: The eerie force accelerating the expansion of the universe
Antimatter is the strange, evil twin of regular matter, and it’s thought to have been mostly banished from our universe. But could it still be lurking out there in large clumps, even as stars? Astronomers have now identified a few signals that could be… Continue reading Stars made of antimatter could be lurking in our galaxy
Moons orbit planets, planets orbit stars, and stars in galaxies orbit supermassive black holes. And that’s more or less where the chain ends, because the super masses involved tend to anchor those black holes in place. But now, researchers have found e… Continue reading “Restless” supermassive black hole may be wandering round its galaxy
Faster-than-light (FTL) travel is a staple of sci-fi, hand-waving away multi-millennia journeys between stars. Such a technology would of course be incredibly handy to us in the real world, and while these “warp drives” have been considered theoretical… Continue reading New theoretical warp drive design clears “negative energy” barrier
Last year scientists detected gravitational waves from what appeared to be the most massive black hole collision ever recorded. But now an international team of astrophysicists has proposed an exotic alternative – the data may actually favor a collisio… Continue reading Invisible “dark matter” stars may explain puzzling gravitational waves
Astronomers have discovered a nearby system of exoplanets with unusually orderly orbits but disordered densities. Five of the six planets circle the star in a rare rhythmic dance called a resonance chain, and the types of planets are far more shuffled … Continue reading Exoplanet system discovered with strange balance of order and disorder
Curing cancer is a noble goal and all, but sometimes scientists just want to see what happens when you give octopuses ecstasy. From medical marvels to wild speculations about time travel, aliens and the end of the universe, New Atlas revisits some of 2… Continue reading Talking mummies and time travel rules: Strangest science stories of 2020
