NASA’s Astronomy Picture of the Day

In today's image, we see galaxies in the process of colliding. The collision will allow large gas clouds to merge and compress, causing star formation rates to increase. We see this in the many large, blue star cluster visible around the image. In a few hundred million years, the collision will have finished and we will have just a single, ordinary galaxy left behind.

In today's image, we see the ongoing construction of the ELT - Extremely Large Telescope. This is expected to be completed later this decade and will be a 40-meter telescope. In the sky above, we see our Milky Way Galaxy as well as two satellite galaxies known as the Magellanic Clouds.

In today's image, we see the full moon as it rises over the horizon. The full moon is always directly opposite to the Sun in the sky which makes it 180 degrees (π radians) away from the Sun in the sky.

In today's image, we see the Seagull Nebula. This is an example of an emission nebula which glows red with the light of hydrogen gas that has been excited by ultraviolet light from newly formed hot stars.

In today's image, we see the exhaust from a SpaceX Falcon 9 rocket launch. Because of the high winds, the exhaust was twisted into a spiral pattern here. In addition, in the background we can see the green color of the aurora.

In today's image, we see multiple images of the full moon as it descends toward the horizon. Because the image was taken near Earth's equator, it descends almost straight down instead of at an angle. On the shore below, we see the blue glow of bioluminescent plankton.

In today's image, we see a total eclipse as seen from Antarctica in 2003. A total eclipse occurs when our Moon passes in front of the Sun and blocks out its light. This allows us to see the Sun's outer atmosphere (corona) around the limb of the Moon. Another total solar eclipse will be visible from pats of North America on April 8 of this year.

In today's image, we see Comet Pons-Brooks which will make its closest approach to our Sun (perihelion) on April 21 of this year. In addition, we can see two galaxies in our Local Group - the Andromeda Galaxy and the Triangulum Galaxy near the top of the image.

In today's image, we see the Tarantula Nebula also known as 30 Doradus. This is a massive star forming region located in the Large Magellanic Cloud. This region is also home to the closest supernova seen in modern times, SN 1987A.
