While the existence of extra dimensions is a cool idea, it's currently not supported by any evidence
The astronomers estimate that this galaxy will deplete itself of gas in only a few hundred million years.
Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.
The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.
If you think you've met the wildest exoplanet yet, you haven't learned about TOI-4507 b. This strange world breaks almost every known rule for how planets should behave.
If the universe is expanding, then what is it expanding into, and what is it expanding from? Where's the edge of the universe, and where is its center?
We actually know very little about what's going on inside Uranus and Neptune, causing researchers to propose that these planets be called "rocky giants" instead.
As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing them into tiny targets.
NASA plans to send the ISS into Earth's atmosphere in 2030, and it has no plans for a replacement — at least, not directly.
It will take the most sensitive instruments ever imagined to reveal ripples from the Big Bang, but they could change our understanding of the entire universe.
Astronomers just ruled out merging black holes as a possible solution to a giant discrepancy plaguing cosmology.
A galaxy in the early universe was rich with oxygen, astronomers have found. The discovery raises questions about how early life could have first appeared in the universe.
Some stars in the universe grow to 300 times larger our own sun. But how do they get so big, and how do they sustain their mass?
Ultimately, we do not understand where glitches come from or exactly what's going on inside pulsars.
The theorists predict that the beginning of the end will be in about 10 billion years — less than the present age of the universe.
In a recent contest, teams of researchers competed to see who could train an AI model to best pilot a spaceship. The results suggest that an era of autonomous space exploration may be closer than we think.
Unfortunately, any work you do in the universe will have to be done the old-fashioned way.
The vast, seemingly empty spaces between galaxies are not entirely empty. So what's in these cosmic voids?
New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that absolutely soaked the early cosmos.
New research suggests there may be a narrow window of possibility for life to persist on the icy moons of the outer solar system.
There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from?
The physical constants of the universe appear to favor the existence of life. So why are we here?
New research has found that lightning, while not very common, can occur on tidally locked exoplanets like our nearest neighbor, Proxima b.
Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe.
