NASA’s Astronomy Picture of the Day Robert M Wagner

In today's image, we see a small open cluster of stars. Some of the brighter stars seem to form the number 37 in the sky. While 42 may have been more appropriate for this who have read The Hitchhiker's Guide to the Galaxy, it is still an interesting pattern of stars in our sky.

In today's image, we see the large sunspot group known as AR 3664 which has been very active recently, sending solar flares and coronal mass ejection in the direction of Earth and giving up so beautiful auroral displays.

In today's image, we see the red aurora as observed over Poland. The aurora have been especially strong the past couple of days because of the numerous coronal mass ejections from the large sunspot group currently moving across the face of the Sun.My podcasts are available in video form through this YouTube Channel (https://www.youtube.com/channel/UCWksELVw1LfYg6TiLQyjByw).This Podcast is an authorized New Media Mirror Site for APOD.

In today's image, we see the giant sunspot group AR 3664 which is currently crossing the face of the Sun. Sunspots are active regions on the Sun, slightly cooler than the surrounding surface. They are also associated with solar flares and coronal mass ejections when can affect us here on Earth and also contribute to auroral activity.

In today's image, we see a simulation showing the merger of two black holes. This simulation depicts what would have been happening during the first detection of gravitational waves in 2015. As the black holes spiral together, their rapid motion releases gravitation waves that we were able to detect at a distance of 1.3 billion light years.My podcasts are available in video form through this YouTube Channel (https://www.youtube.com/channel/UCWksELVw1LfYg6TiLQyjByw).This Podcast is an authorized New Media Mirror Site for APOD.

In today's image, we see the giant elliptical galaxy, M87. In addition, we see images of the central jets and the famous image from 2017 by the Event Horizon Telescope of the supermassive black hole at the center of the galaxy.My podcasts are available in video form through this YouTube Channel (https://www.youtube.com/channel/UCWksELVw1LfYg6TiLQyjByw).This Podcast is an authorized New Media Mirror Site for APOD.
