Astronomers predict the orbits of potentially hazardous comets from meteor showers
Comets have long been seen as omens and portents, and it's easy to understand why. They first appear as faint smudges of light in the sky, sometimes fading soon after and sometimes becoming brighter than the planets, with a long, glowing tail. They h.....»»
The mortality rate of bats at modern-day swimming pools is comparable to that at Messel 47 million years ago
More than 500 bat fossils have been discovered at the Messel Pit UNESCO World Heritage Site over 42 years. A new study, published today in the journal Palaeobiodiversity and Palaeoenvironments, investigates whether the high number of fossils is due t.....»»
