NASA said in February it intends to keep operating the International Space Station until the end of 2030, after which the ISS would be deorbited and crashed into a remote part of the Pacific Ocean. Commercially operated space platforms would replace the ISS as a venue for collaboration and scientific research, NASA said.
Tuesday’s releases showed parts of the universe seen by other telescopes. But Webb’s sheer power, distant location from Earth and use of the infrared light spectrum showed them in a new light that scientists said was almost as much art as science.
Chicago-area birds are nesting and laying eggs earlier than ever before. A mysterious meteor burns up over Papua New Guinea. A fossil could rewrite the history of the evolution of life on Earth. And a disturbing finding about microplastics.

An Atlas V rocket blasted off before dawn, sending Lucy on a roundabout journey spanning nearly 4 billion miles. Researchers grew emotional describing the successful launch — lead scientist Hal Levison said it was like witnessing the birth of a child. “Go Lucy!” he urged.
A NASA mission to deflect an asteroid – it’s been the premise for more than one Hollywood movie – but next month NASA launches its DART mission that aims to do it for real.
Virgin Galactic founder Richard Branson on Sunday became the first billionaire to ride his own rocket ship to space. But beyond being the ultimate joyride for billionaires, will commercial space travel take off as an industry accessible to the rest of us?
