When China tightened export licences on seven rare-earth elements in April 2025, Western governments responded in the same way as they have to every other critical-minerals shock of the past five years. The European Union accelerated the issuing of extraction permits under the Critical Raw Materials Act. The United States expanded subsidies for domestic refining…

  NEW DELHI: India’s space startup Skyroot Aerospace completed its first orbital flight on Saturday, making India the third country in the world with a private company capable of such a feat. The Vikram-1 rocket lifted off at 12.05 p.m. from the Satish Dhawan Space Center in Sriharikota, an island off the Bay of Bengal….

K2-18b has become one of the most closely watched exoplanets in recent years. The planet lies about 124 light years away in the constellation Leo and orbits within the habitable zone of a red dwarf star. Observations from the James Webb Space Telescope have revealed an atmosphere rich in carbon dioxide and methane, making K2-18b…

In 1993, a team led by the planetary scientist Carl Sagan tentatively concluded that there is life on Earth. Not much of a deduction, you might think — except that the researchers confined their evidence to observations made by the Galileo spacecraft, which had flown past our planet three years earlier on a looping journey…

From small boats off Norway’s Lofoten Islands, researchers used poles to attach recording tags to the backs of sperm whales. Suction cups held the devices in place as the whales slipped below the surface. As the animals stopped swimming and rotated into their upright resting positions, microphones on the tags recorded bursts of bubbles. Those…

The most powerful solar storms to strike Earth may pack a bigger punch than scientists realized, according to a new study that suggests the impacts of extreme space weather have been underestimated. Researchers found evidence that the apparent upper limit on Earth’s response to the strongest solar storms may be an artifact of how solar…
