A strange 'cloud' was spotted across Tampa Bay, Florida early Wednesday morning. The phenomenon, known as noctilucent clouds, was caused by a recent SpaceX Starlink launch in Cape Canaveral. These high-altitude clouds made of ice crystals are able to reflect sunlight, giving them a glowing appearance.

Why it matters

Noctilucent clouds are an uncommon sight, especially at lower latitudes like Florida. While climate change may be causing them to appear more frequently, rocket launches can also create these types of clouds by expelling particles into the upper atmosphere. This event highlights how space technology and exploration can have visible impacts on the natural world.

The details

The noctilucent cloud was spotted by residents across the Tampa Bay area shortly before 6 a.m. on Wednesday. Meteorologist Juliana Meija of WFLA explained that these clouds are made up of ice crystals high in the atmosphere that are able to reflect sunlight, giving them a glowing appearance. According to NASA, noctilucent clouds can only be seen during twilight hours when the sun is just below the horizon.

The takeaway

This event showcases how space technology and exploration can have visible impacts on the natural world, with rocket launches capable of creating rare atmospheric phenomena like noctilucent clouds. As space activity continues to increase, it will be important to monitor and understand these types of effects.
