Back in 2015, the Kepler Space Telescope spotted a strange planet orbiting a red dwarf in the constellation of Leo, some 100 light years from Earth. K2-18b, as it was designated, is about eight times more massive than Earth with twice the radius, making it a type of planet astronomers call a mini-Neptune. It orbits its parent star in just 33 days, placing it firmly within the habitable zone, the region around a star where liquid water can exist.Precise conditions on such a planet are impossible ...read more

Happy leap year! Feb. 29, 2024, is leap day and marks an ongoing, longstanding correction to the calendar we use.In most years, our calendar contains 365 days. But Earth actually takes 365.2422 days (let’s call it 365¼ days) to orbit the Sun. As you might imagine, if we let these quarter days add up, we’d quickly be celebrating the 4th of July in America when it’s snowing.So, we add a full day every four years … almost.

No one looks forward to getting old; in fact, it can seem pretty scary. But you might be surprised to learn that aging brings some benefits. All things being equal —  given reasonably good health and a secure economic situation — older people tend to be happier than younger people, according to a growing body of research. A widely cited study published in 2016 in the Journal of Clinical Psychiatry looked at more than 1,500 people from 21 to 100 years old and found that mental health increas ...read more
