Astronomers discover a new strategy for detecting exoplanets: look for aligned binary stars that reveal hidden worlds more ...

Planet 9 could soon be discovered as astronomers ‘narrow in’ on hidden world in Solar System. ... a research effort to map hundreds of millions of galaxies to shed light on dark energy.

A new paper by physicist Edward Witten proposes hunting Planet 9 using a fleet of laser-launched probes like Breakthrough Starshots'.

Planet 9 likely isn't a stolen exoplanet after all. ... influencing the behavior of every other planet in our system. That's why when spacecraft like Juno map the interior Jupiter, considered ...

It’s now believed that Planet 9, if it exists, will be about half the mass of Uranus. Maybe that doesn’t sound like much, but it’s more than the combined heft of Mercury, Venus, Earth and Mars.

The implications were dramatic: with Planet Nine in tow, 2017 OF201 is thrown out of the solar system within 100 million years, an eyeblink on cosmic time. Without Planet Nine, the object’s ...

Almost a decade after astronomers proposed the existence of Planet 9, an unseen extra planet in the distant reaches of the solar system, they still haven’t all agreed whether it’s real or not ...

Planet 9 would be too distant to be seen by reflected light, so you’d have to look for it by its faint infrared glow. And with a mass of only five Earths, it wouldn’t give off much heat.

Here's why the Star Wars trope of incomplete star maps and missing planets makes perfect sense. Menu. Reel Science. The Dumbest Star Wars Trope Is Also Somehow The Most Scientifically Accurate.
