Super Planetary-Motion Smackdown: Kepler v. Newton

The ancient Greeks studied the earth and the sky, but their basic model had all the objects (sun, moon, and planets) moving in circles around us.Is there a more fundamental model that could explain both the motion of a planet orbiting the sun and the motion of the moon orbiting Earth?

Elon Musk: Humanity Is a Kind of 'Biological Boot Loader' for AI

So among the set of actions we can take, that are likely to increase the scope and scale of consciousness such that we are better able to understand the nature of the universe, one of those actions is to become a multi-planet species or ensure that life is multi-planetary, not because I think—it's not not from the standpoint of it just being an escape hatch, or because I think that Earth is doomed.

Forget the Moon—We Should Go to Jupiter’s Idyllic Europa

Jupiter's moon Europa is like the Brigadoon of the solar system: an idyllic moon with an ice-covered ocean that may hide some form of life, even though plans to send a spacecraft there keep receding farther and farther away into the Jovian mists.

NASA Will Send a Helicopter to Hunt for Life on Saturn's Biggest Moon

The Dragonfly mission will spend two years flying around the surface of Titan, studying the moon’s composition and searching for signs of life. On Wednesday, NASA announced it will send a spacecraft to the surface of Titan , Saturn’s largest moon and one of the leading candidates for finding extraterrestrial microbial life in our solar system.

How to Watch SpaceX's Falcon Heavy Launch a Solar Sail Tonight

The Planetary Society pressed on and a decade later launched the LightSail 1 into low Earth orbit. In 2010, the Japanese space agency launched IKAROS , which used solar sailing as its only form of propulsion on a mission to Venus and demonstrated that the technology actually worked for the first time.

Bezos Says Amazon Will Bet Even Bigger Despite Antitrust Probes

“We need to be doing things where if they work, they have to be able to move the needle for us," Amazon CEO Jeff Bezos said. “We can’t do things that if they work they’ll be small,” Bezos said, in conversation with Amazon’s forecasting chief Jenny Freshwater.

When the Large Hadron Collider smashes lead ions together, the collisions regularly reach temperatures of 5.5 trillion degrees Celsius, or 10,000 times hotter than the core of the sun.

The Mystifying Case of the Missing Planets

The Mystifying Case of the Missing Planets

Dragomir said the radius gap points to possible rules both about how planets are formed, and what happens to them early on. Though some kind of atmosphere loss is a reasonable guess, it is just one of three general ideas, said Sara Seager, an astronomer at MIT who is deputy science director for the TESS mission.

Minecraft Earth Wants to Be the Next Pokémon Go—But Bigger

Back in the Minecraft offices in Redmond, Washington, where they shared a building with Halo studio 343 Industries, the team would put people in the HoloLens and then send AR sheep walking down the hallway toward them—“slowly, certainly not threateningly,” Persson says now, sitting in a conference room right next to that hallway.

Climate Adaptation Isn’t Surrender. It’s Survival

For one thing, science fiction fans are not new to post-apocalyptic scenarios, whether it’s robot uprisings, mysterious unnamed disasters that leave the planet uninhabitable, total Wall-E style environmental collapse, or actual climate-change-inspired disaster, as in Kim Stanley Robinson’s New York 2140 , which imagines a mostly drowned Earth after 100 feet of sea level rise over just a few decades.

Quiet Evidence of People's Impact on Earth

It supports something else scientists have been saying for a while: Human activity has so drastically impacted the planet that it's entering a new geological epoch, called the Anthropocene. George Marazakis documents traces of this activity, from fish farms to salt works, while driving through Greece for his series A Cure for Anthropocene .

Move Over, San Andreas: There’s an Ominous New Fault in Town

When I asked Caltech geologist Brian Wernicke, a giant in the field of global geophysics, if it was possible that Faulds was paying too much attention to the Walker Lane, he replied, quickly and without irony: “Well, it's the most interesting place in the world.” In terms of understanding how continents deform and how seismic hazards relate to plate tectonics, he added, “it's an unparalleled natural laboratory.”.

The Odd Physics of Rey's Backflip in Star Wars: Episode IX

For Rey jumping over (I assume she makes it) a TIE fighter, I'm just going to look at her vertical motion. There is some type of TIE fighter zooming toward Rey. You would think her goal is to jump over the spacecraft, but who really knows.

As the World Warms, Clouds Could Disappear—Catastrophically

This is one of several lines of evidence, Bretherton said, “that would favor the range of predictions that’s 3 to 5 degrees, not the 2- to 3-degree range.” Schneider’s new simulation with Kaul and Pressel improved on Bretherton’s earlier work primarily by connecting what happens in a small patch of stratocumulus cloud to a simple model of the rest of Earth’s climate.

“If you have good enough data and good enough sensing technologies, such as the seismometer network in California or the hurricane-hardened WeatherFlow anemometer stations on the East Coast, you can get that data and very quickly work out whether someone should be getting paid,” says Samuel Jay Gibson, of the Capital and Resilience Solutions Group at the catastrophe risk modeling firm RMS.
