In 2006, the International Astronomical Union came up with a new way to classify planets that famously saw Pluto downgraded. Now a new row has started as astronomers try to define exoplanets What is a planet? Despite decades of trying, astronomers still haven’t found a definition that everyone can agreeContinue Reading
With its mirrors now focused, the observatory’s science instruments are now being readied for work After James Webb Space Telescope officials released a stunning image of a single star, the team is ready to get other telescope parts in line with the observatory’s mirrors. The $10 billion telescope successfully alignedContinue Reading
Most bears live in the Northern Hemisphere; polar bears are no exception. The Arctic and Antarctica, while similar habitats in some ways, are home to very different creatures. Both poles host a variety of seal and whale species, but only the Arctic is home to Earth’s largest bear, the polarContinue Reading

The study, published Monday (March 7) in the journal Nature Climate Change, suggests that more than 75%Continue Reading
