another crisis coming right up

Birds are famous for communicating vocally, but many have other options, too. Some communicate by dancing, for example, or by showing off their feathers. And according to a new study, at least one bird species does something more often associated with humans and great apes: symbolic gesturing. A songbird called the Japanese tit (Parus minor) uses fluttering wing movements to signal "after you," the study's authors report, similar to the way humans extend one open hand to let another person go first.

The tool bag is now orbiting our planet just ahead of the ISS with a visual magnitude of around 6, according to EarthSky. That means it is slightly less bright than the ice giant Uranus, the seventh planet from the sun. As a result, the bag  —  officially known as a crew lock bag  —  is slightly too dim to be visible to the unaided eye, but skywatchers should be able to pick it up with binoculars.  To see it for yourself, first find out when you can find spot the space station over the next few months (NASA even has a new app to help you). The bag should be floating two to four minutes ahead of the station. As it descends rapidly, the bag is likely to disintegrate when it reaches an altitude of around 70 miles (113 kilometers) over Earth.
