More Evidence that Planet 9 is Really Out There

Artist's impression of Planet Nine as an ice giant eclipsing the central Milky Way, with a star-like Sun in the distance. Neptune's orbit is shown as a small ellipse around the Sun. The sky view and appearance are based on the conjectures of its co-proposer, Mike Brown.

What’s going on in the distant reaches of our Solar System? Is there a Planet 9 out there?

Out in the frigid expanse of our System, there are bodies on orbital paths that don’t make sense in terms of our eight-planet Solar System. There seems to be an undiscovered body out there, several times more massive than Earth, shaping the orbits of some Kuiper Belt Objects (KBOs), and driving astronomers to look deeper and more thoroughly into the extreme reaches of our System.

What they’re looking for is the mysterious, and so far unproven, ninth planet.

Remember Far Out, the distant planet at the far reaches of the Solar System, that was discovered in December, 2018? Well, it has been kicked unceremoniously off its pedestal as the most distant object after a short, two-month reign. In its place is the very newly-discovered FarFarOut (FFO.)

And if it weren’t for a heavy snowfall, things might have turned out differently.

Massive Volcanic Eruptions 66 Million Years Ago Happened Almost Exactly When the Dinosaurs Died Off

Everyone knows an asteroid strike wiped out the dinosaurs, right? Lots of evidence shows that the Chicxulub impact event had terrible consequences for the dinosaurs. But the picture is a little more complicated than that. Extreme volcanic activity may have contributed to the extinction.

Moons have the coolest names, don’t they? Proteus, Titan, and Callisto. Phobos, Deimos, and Encephalitis. But not Io. That’s a stupid name for a moon. There’s only two ways to pronounce it and we still get it wrong. Anyway, now we have another cool one: Hippocamp!

Okay, maybe the new name isn’t that cool. It sounds like a summer camp for overweight artiodactyls. But whatever. It’s not every day our Solar System gets a new moon.

Japan’s Hayabusa2 spacecraft has completed an important part of its mission to asteroid Ryugu. The spacecraft descended to the surface of the asteroid to collect two samples with its sampling horn. We don’t know for sure if samples were successfully collected, but all indications are that the sampling mission went well.

Billions of years ago, Mars was likely a much warmer and wetter place than the cold, dry, barren world we see today. Whether there was life there or not remains an open question. But there’s a massive, growing wall of evidence showing that Mars may have had the necessary conditions for life in the past, including at least one system of river valley networks.

Antarctica is About to Unleash an Iceberg Twice the Size of New York City

An ice shelf in Antarctica is about to give birth to a baby. This baby is a giant, spawned by growing cracks in the Brunt Ice Shelf. It’s not clear what this’ll mean to the scientific infrastructure in the area, and to the human presence, which were both established in the 1950s.

Japan’s Hayabusa2 mission is about to get down to business. After arriving at asteroid Ryugu at the end of June 2018, and dispatching its tiny rovers to the surface, the spacecraft is about to approach the surface of the asteroid and get some samples.
