In today's image, we see an animation showing the orbit of comet Swift-Tuttle which is the comet responsible for the Perseid Meteor shower that occurs every year in mid-August. Here we can see how the stream of material comes very close to Earth's orbit, giving us the sower go meteor particles each year.

In today's image, we see the comet known as Swift-Tuttle. It is a periodic comet which means it returns to the inner solar system at regular intervals. In this case, every 133 years. It is also the comet responsible for the debris that becomes the Perseid Meteor shower which will peak this weekend.

In today's image, we see a storm cloud as seen over Texas in 2021. The structure of the cloud is caused by Earth's atmosphere and the different temperatures and storm fronts morning through it. The colors are caused by light from the Sun and are different because different parts of the cloud see the Sun at different heights above the horizon.

In today's image, we see a rendering of our galaxy. We will move through the galaxy, using positions and distances determined by the Gaia satellite which helps give us a 3D view of our galaxy. In many cases, we are getting accurate distances now for many stars for the first time.
