Planet Nine: The Hidden World That Might Be Real — And the Telescope That Will Find It
In 2016, two Caltech astronomers announced evidence for a massive planet lurking at the edge of the solar system — unseen, unfilmed, detected only by the gravitational chaos it leaves behind. A decade later, the debate is fiercer than ever. A new object called Ammonite challenges the hypothesis. The Vera Rubin Observatory has begun scanning the sky. And by late 2027, we may finally know if Planet Nine is real.
Beta Pictoris d: The Hidden Giant Found by Smelling Its Atmosphere, Not Photographing It
For eleven years, a giant planet sat inside pictures of one of the most photographed stars in the sky — and nobody saw it, because it was never a point of light. Two independent teams confirmed Beta Pictoris d the same week using entirely different methods: one dug it out of a decade of ground-based infrared archives, the other detected it by its atmospheric chemistry before anyone photographed it.
The End of the Universe: A Countdown From the Last Star to Heat Death
Every star that has ever shone will one day go out. The universe is dying — and it has been dying since the moment it was born. This is the complete timeline to nothing: from our Sun's death in 5 billion years, to red dwarfs that smolder for 10 trillion years, to evaporating black holes, to the final heat death when nothing changes ever again.
The Wandering Monster: A Black Hole Weighing a Million Suns Was Caught Eating a Star 30,000 Light-Years From Home
Astronomers caught a ~1 million solar-mass black hole shredding a star 30,000 light-years from its galaxy's center — the first tidal disruption event ever seen this far from a galactic core, ten times farther than the previous record.
The Great Attractor: Something Is Pulling Our Entire Galaxy Across the Universe
The Milky Way is racing toward a hidden point in space at 2 million km/h. Astronomers call it the Great Attractor — a gravitational anomaly behind the dust of our galaxy, dragging 100,000 galaxies including our own toward a single unknown point.
Who Left a Rocket on the Moon? The Mystery of the Double Crater
In March 2022, a rocket crashed into the Moon at 8,700 km/h. For weeks, nobody could agree on whose rocket it was — SpaceX or China. The double crater it left behind exposed lunar secrets and a legal vacuum.
4,000 Miles Down: The Mind-Blowing Secrets Hidden Inside Earth's Inner Core
Earth's inner core is hotter than the Sun's surface, spins faster than the planet itself, and may hold the key to understanding how our magnetic field protects all life. Here's what scientists have discovered 4,000 miles beneath your feet.
NASA's Psyche Spacecraft Just Aced a Mars Flyby — Here's What It Found
NASA's Psyche spacecraft used Mars as a gravitational slingshot, capturing stunning timelapse video and testing instruments that will soon study a metal-rich asteroid.
BALLS on the Moon: China Set to Launch Africa's 1st Lunar Science Mission in 2029
Africa's first space exploration mission aims to send a trio of spherical probes named BALLS to the lunar south pole aboard China's Chang'e-8 lander in 2029.
