Can life begin on a moon without a sun
Free-Floating Planets, or as they are more commonly known, Rogue Planets, wander interstellar space completely alone. Saying there might be a lot of them...
Scientists capture a stunning “cosmic egg” as a dying star
NASA’s Hubble Space Telescope has captured a striking new image of the Egg Nebula, a rare and short-lived object formed as a star nears...
How a single Martian storm triggered massive water loss
Mars’ water disappeared somewhere, but scientists have been disagreeing for years about where exactly it went.
Data from rovers like Perseverance and Curiosity, along with...
Why so few planets can support life
Life needs more than water and the right temperature to exist.
New research suggests that only a small number of planets ever get the chemical...
Dead stars may be hiding the missing mass of galaxy clusters
Galaxy clusters, the largest structures held together by gravity in the universe, may be far heavier than scientists once believed.
New research suggests that much...
A giant star is changing before our eyes and astronomers are watching in real...
For decades, astronomers have been watching WOH G64, an enormous heavyweight star in the Large Magellanic Cloud, a galaxy visible with the naked eye...
Are there hidden dimensions to the universe
This is Part 1 of a series on large extra dimensions.
I always say that one of the things that separates real science from pseudoscience...
Astronomers discover a hidden factory of organic molecules in a dust-shrouded galaxy
rich mix of organic molecules deep inside a nearby galaxy, offering a new glimpse into how the basic ingredients of chemistry may form in...
A strange Martian dust storm offers new clues to how Mars lost its water
Mars today is a cold, dry desert, but its surface tells a very different story.
Ancient river channels, lake basins, and minerals formed in water...
This mysterious particle may be proof that black holes can explode
In 2023, physicists detected something that should not have existed: a single subatomic particle called a neutrino carrying an almost unimaginable amount of energy.
This...
Is there really a black hole at the Milky Way’s center—or something even stranger?
For decades, astronomers have believed that a supermassive black hole sits at the heart of our galaxy.
This object, known as Sagittarius A*, is thought...
Is there a link between primordial black holes, neutrinos, and dark matter
Humanity has worked itself into a position where we can detect a single high-energy particle from space and wonder where in Nature it came...

Scientists solve 40-year mystery over Jupiter’s X-ray aurora
Scientists have solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes.
The X-rays are part of Jupiter's...
Why Venus died
Venus is only slightly smaller than the Earth, and so has enjoyed billions of years of a warm heart. But for this planet, sometimes...
Do hycean worlds have smaller habitable zones
Hycean worlds are also called ocean worlds.
They're planets covered in oceans that also have thick hydrogen atmospheres. There are no confirmed Hycean worlds—also called...
Scientists discover two supermassive black holes headed for a collision
Astronomers have spotted a distant pair of titanic black holes headed for a collision.
Each black hole's mass is more than 800 million times that...
Why asteroids tumble instead of spin—gaia data reveals the answer
Asteroids may look like simple space rocks, but their movements hide complex physics.
Some spin neatly on their axes, while others tumble chaotically, flipping in...
