Stephen Hawking: Earth Could Turn Into Hothouse Planet Like Venus

Earth could turn into a hothouse planet like Venus, with boiling oceans and acid rain, if humans don’t curb irreversible climate change, physicist Stephen Hawking claimed in a recent interview. But most climate experts...

Climb Aboard a Boeing 747 That NASA Turned Into the World’s Biggest Flying Telescope | WIRED

To get the best space observations possible, NASA scientists fly around the world in a highly modified 747 carrying a giant telescope.

Climate change did not “cause” Harvey or Irma, but it’s a huge part of the story

Climate change did not “cause” Harvey or Irma, but it’s a huge part of the story

Climate is not central, but by the same token it is grossly irresponsible to leave climate out of the story, for the simple reason that climate change is, as the US military puts it,...

Plate Tectonics May Have Begun a Billion Years After Earth’s Birth

Plate Tectonics May Have Begun a Billion Years After Earth’s Birth

Precisely what Earth looked like before plate tectonics, which drive these chunks of crust around, bumping and grinding into one another, is an open question. During the Archean eon 4 billion to 2.5 billion years...

‘Halos’ on Mars Suggest Conditions for Life Lasted Longer Than Thought

Shortly after touching down inside the Red Planet’s 96-mile-wide (154 kilometers) Gale Crater in August 2012, NASA’s Curiosity rover found evidence that the area had harbored a potentially habitable lake-and-stream system in the ancient past. The...

Bad News for Life: TRAPPIST-1 Planets’ Atmospheres May Have Been Destroyed

When first observed thirteen years ago, Cassini researchers concluded that the propeller gashes “are much like the wave pattern that trails after a speedboat as it skims across a smooth lake.” But, Saturn’s rings...
