Creation of the next supercontinent will make most of Earth unlivable to mammals.

NASA used AI and satellite photos to map carbon of over 10 billion trees in Africa. NASA scientists scanned over 10 billion individual trees in Africa's drylands using commercial, high-resolution satellite pictures and artificial intelligence (AI) to estimate the amount of carbon stored outside of the continent's vast tropical forests.

New simulations show how weaker, low-luminosity jets produced by a galaxy's monster black hole interact with their galactic environment.

The Event Horizon Telescope collaboration captured the world’s imagination in 2019 with a mind-bending photograph of a supermassive black hole’s shadow at the heart of galaxy M87. Imagine the light show from two such monsters locked in a space-warping dance, distorting and redirecting light emitted from the super-heated gas swirling in the accretion disc that surrounds each one. That’s what researchers at NASA’s Goddard Space Flight Center set out to accomplish with a computer visualisation showing two gravitationally bound supermassive black holes, one with 200 million times the mass...

Key facts: The system, also called TIC 168789840, is the first known sextuple composed of three sets of eclipsing binaries, stellar pairs whose orbits tip into our line of sight so we observe the stars alternatively passing in front of each other. Each eclipse causes a dip in the system’s overall brightness. Astronomers designate the binaries by the letters A, B, and C. The stars in the A and C systems orbit each other roughly every day and a half, and the two binaries orbit each other about every four years. The B binary’s members circle each other about every eight days, but the pair is...
