We’ve been receiving calls into the WTOP Newsroom reporting phenomena in the skies that people can’t explain — but our space expert can.

Night time sky gazers can see meteors — bright and dim, airplanes, aurora, stars, planets and oh, yes, satellites. Lots of them. Smartphone apps are available to track and identify these moving star-like objects of which there are currently over 11,000, with Starlink being a good chunk of the total.

When SpaceX launches a new group of its Starlink satellites check here— it is very likely that they will be spotted as a group, or “train” going across the sky. They can really grab our attention when they do.

If you see something like this you can go to this website and check.

Thankfully, WTOP’s space expert joined us live Sunday night to break it down.
