Not only does this give us a look at the scaffolding of the universe, we found some new galaxies too!
The laws of physics state that you can't create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?
Bloodcurdling war cries, shrieking elephants, and whistling arrows all made soldiers flee in terror.
We can describe what we see happening, but we don’t understand why. Despite our vast cosmic knowledge, enormous unknowns remain. The quantum fluctuations inherent to space, stretched across the Universe […]
A new study discovers how blazars shoot out jets of radiation towards Earth.
How Nobel Prize winner physicist Lev Landau ranked the best physics minds of his generation.
James Gillray's 'plumb-pudding' caricature is "probably the most famous political cartoon of all time."
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
LIGO just announced the second neutron star-neutron star merger ever seen in gravitational waves. It doesn’t match the first. On August 17, 2017, an event occurred that forever changed how we […]
For years, astronomers have been puzzled by an excess of antimatter particles. Unfortunately, dark matter is probably not the solution. When you look out at the Universe, what you see […]
With advanced laser technology and an appropriate sail, we could accelerate objects to ~20% the speed of light. But would they survive?
Both views are equally spectacular, but unequally informative. Every so often, a creative amateur project highlights our professional achievements. This mosaic shows the region between the constellations of Cygnus and […]
When you’re trying to peel back the veil obscuring the fundamental nature of matter, you have to look absolutely everywhere. Sometimes, the solution to a puzzle you’ve been stymied by […]
Two new papers say everything we knew about black holes was wrong.
When you hear ‘quantum,’ you probably think of splitting everything into discrete, indivisible chunks. That’s not necessarily right. If you want to learn what the Universe is made out of […]
And Dr. Jill Tarter never once lost her composure. One of the most fascinating questions in all of science is: “are we alone?” Since our distant ancestors first gazed at […]
A man paralyzed from the waist down was able to voluntarily control and move his legs with the help of an electrical implant in his spine.
In 2017, we saw gravitational waves a neutron star merger for the first and only time. And it keeps getting more interesting. On August 17, 2017, a cosmic signal arrived […]
The Israeli historian has plenty to say.
