As the search for "Planet Nine" in the outer solar system continues, new research suggests there may be an Earth twin buried deep within the frozen waste of the Kuiper Belt beyond Neptune.
According to the science, Earth should actually be experiencing a cooling period right now.
Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'
While there are hints that dark energy may be 'phantom,' its true nature remains frustratingly elusive, a new study reports.
Black holes seem to get all the attention. But what about their mirror twins, white holes? Do they exist? And, if so, where are they?
Whether you're a frequent jet-setter or a couch potato, you travel much more than you think, thanks the motion of the Earth, sun, Milky Way galaxy and more.
The modern scientific fields of astronomy and physics stretch back for centuries, and so naturally they've accumulated a lot of interesting names for objects, ideas, and phenomena.
Meet the 'bubbletrons' — theoretical particle accelerators that may have helped build the universe as we know it.
Pseudoscience is a practice that, from the outside, looks like science, but upon closer inspection, is revealed to be nothing but. And what makes a practice look like science?
Earth has held a stable orbit for over 4 billion years but what would happen if we changed Earth's orbit so to avoid the sun's violent demise?
Researchers have found a new way to measure dark energy — the mysterious force that is causing the expansion of the entire universe to accelerate — using data from our own cosmic backyard.
One astrophysicist is suggesting we remove Saturn's status as a gas giant, saying the planet tried but didn't quite make the cut.
Space mysteries Ever wondered how light slows down when passing through a material? Here we explore why the answer is not that straightforward.
In the early 20th century, a team of women went far beyond their job descriptions, not to mention the societal norms of the time, to revolutionize astronomy.
Why didn't the universe collapse into a black hole during the earliest moments of the Big Bang? Simply put, because that's not how you make a black hole.
We may have already found evidence of an evolving, dynamic kind of dark energy, in the form of the radiation emitted when the first stars appeared in the universe.
Dark matter, the invisible material that makes up the vast majority of the universe's mass, may collect itself to form atoms, a new simulation shows.
Astronomers have used the youngest objects in the Milky Way to build a new map of the galaxy's spiral arms, and the results are far messier than expected.
In a distant star system, a sunlike star orbits an invisible object that may be the first example of a 'boson star' made of dark matter, new research suggests.
A new paper discusses how light interacts with theoretical objects called "topological solitons" — kinks in the fabric of space-time that look just like black holes.
New research suggests that Hycean exoplanets would suffer from a catastrophic runaway greenhouse effect, causing their oceans to boil away.
A large population of small black holes could have flooded the young cosmos with particles and radiation, creating their own black hole-powered Big Bang, physicists propose in a new paper.
These cosmic rays typically come from the extremely distant universe, from ultrapowerful events such as supernovas and quasars.
