As the moon rotates around its host planet, this charged gas swipes across Jupiter’s magnetic field lines “like plucking strings on a guitar,” said Nichols, who studies space-based magnetic fields.
In an Monday, the world’s richest man committed $10 billion of his personal fortune to set up the new Bezos Earth Fund, which would support “scientists, activists, NGOs—any effort that offers a real possibility to help preserve and protect the natural world.” The announcement was light on specifics, and it’s not clear yet how the money will be spent .
In response to the argument that we can ditch oil and coal immediately, he points out that renewable technologies are still more expensive and are not as readily available in the economically developing world, where plentiful and cheap fossil fuels are helping pull people out of poverty.
Kitten Bowl VII (2 pm ET): The seventh Kitten Bowl will kick off the day's activities at 2 pm eastern time on the Hallmark Channel and will re-air at 5 pm.Puppy Bowl XVI (3 pm ET): The 16th Puppy Bowl kicks off an hour later, at 3 pm ET, and airs on Animal Planet.
Star Wars films contain few easy shots, but the hardest ones to capture are likely the images fans will remember best.“When you have just enough time in the day to go once more and it finally comes together, there’s no better feeling in the world,” Mahoney says.

But maybe a better way to approach gravity is to think not about being stuck on Earth but about being weightless.“What you’re really doing when you’re experiencing gravity isn’t being heavy in your chair, it’s falling weightlessly in the gravitational field,” says astrophysicist Janna Levin.
In a lot of cases, to understand the character I need to understand literally everything about their world.” To do so, she applies two frameworks: one that focuses on macroworldbuilding (the creation of the physical environment in which the story will take place—planet, continents, climate, ecology, and culture) and one that focuses on microworldbuilding (the societies that result, in all their flavors of social stratification).
Air cofounder Stafford Sheehan introduces hydrogen gas and carbon dioxide gas into the company's reactor.
The powerful Hubble Space Telescope in orbit around Earth takes an astoundingly detailed look at the same planet: You can see its telltale bands, the iconic Great Red Spot, and smaller individual storms.
This year’s award goes to a Canadian physicist, James Peebles, whose theoretical work underpins the current understanding of the universe’s beginnings, and to two Swiss astronomers, Michel Mayor and Didier Queloz, who discovered the first planet orbiting a Sun-like star .
Bigger Change Faster: Integrated Development, Health, and Environment Actions for a Sustainable Future is co-authored by the United Nations Development Programme and the Bridge Collaborative—a partnership led by The Nature Conservancy, PATH, the International Food Policy Research Institute, and Duke University.
As this equation shows, the magnitude of the gravitational force depends on the mass of each object (m1 and m2) and the distance (r ) between them.Think of the planet and space object as a system, where the total energy in the system is constant—there’s no external force acting on it.
"The adoption and use of SEPAL for forest monitoring has exceeded all expectations and its impact on country reporting to the United Nations Framework Convention on Climate Change (UNFCCC) is already a significant improvement compared to previous years," said Tiina Vahanen, Chief, Forestry Policy and Resources Division in FAO's Forestry Department.
The seas continue to take on the atmosphere’s heat, as marine heatwaves cripple ecosystems and less snow and ice threaten water supplies.Let’s begin with the most apparent consequence of climate change in the oceans: global mean sea level rise.
And while this image is incredibly detailed, Cassini was a whopping 870,000 miles above the plane of the rings when it took this photo in 2014.Photograph: NASA/JPL-Caltech/Space Science InstituteThis maelstrom on Saturn is one of the biggest storms ever observed on the planet.
Photograph: Gerald Eichstadt/Sean Doran/NASA/JPL-Caltech/SwRI/MSSSDid you know Jupiter has rings?Photograph: NASA/JPL-Caltech/SwRIThis May, the spacecraft swooped outward in its orbit and captured this stunning photo of Jupiter and its turbulent atmosphere from 11,600 miles away.
We have the Voyager program to thank for some of this week’s spirals: When Voyager 1 first flew past Jupiter in 1979, it photographed the monster tempest swirling around and over on itself, and in 1989 Voyager 2 flew past Neptune and spied a small spiral storm that NASA nicknamed “Scooter.” Farther beyond are galaxies like our own spiral that contain gorgeous illuminated arms speckled with starlight.
The fiery, anti-environment populist has encouraged settlements in the Amazon region, sacked the head of the government agency that monitors deforestation from space, and just this week blamed NGOs for setting the fires to make him look bad.On Tuesday, a satellite took this image of forest fires burning across three Brazilian states.
This 300-year-old storm used to be huge—so big it could hold nearly four Earths, although over the past few decades it has been shrinking and no one knows why.#Space Photos of the Week #Jupiter #solar eclipse.
That, though, would require forest management across swaths of the Arctic, a kind of management we in the US can’t even do right on a small scale .What we’re looking at, then, is yet another complicating factor in the massive complexity that is climate change: When peat burns, it emits lots of CO2, and when peatlands aren’t healthy, they don’t capture any.
The imitation of forward movement in games like Destiny 2 is catnip to a mind stuck in neutral. It's about what videogame players call "grinding"—the act of repetitiously getting resources, experience points, or anything else you might need in a game to achieve your goals.
“I think the results of this paper really add an abundance of caution, that we shouldn't hope that species will adapt to changing climate and changing habitats, that we don't need to do anything,” says Mark Reynolds, lead scientist for the Nature Conservancy’s migratory bird program, who wasn’t involved in the study.
It’s called a solid-state greenhouse effect—light penetrates the surface, passes through the translucent ice, and then hits darker regolith, which warms up. Could an insulating material create a solid-state greenhouse effect warm enough to make Mars habitable?
The more than 2 billion iPhones sold since Apple first launched it exactly 12 years ago have done a lot of good for their owners, but it seems like they’ve been bad news for the planet.
