NASA’s Astronomy Picture of the Day

In today's image, we see the bright star Regulus which is the brightest star in the constellation of Leo. We see almost all stars as points of light because of their relatively small sizes compared to their great distances from us. We also see the Leo I dwarf spheroidal galaxy below Regulus. This is a galaxy in our own Local Group of galaxies.

In today's image, we see a large star forming region in the galaxy M33: The Triangulum Galaxy. This is one of the spiral galaxies in our own Local Group of galaxies. The star forming region is one of the larger known in the Local Group, the largest being he Tarantula Nebula within the Large Magellanic Cloud.

In today's image, we see an example of an emission nebula around a hot massive star. The ultraviolet light from the star excites the gases around it and causes them to glow. Patterns in the gas can be caused by motions of the star itself which has a stellar companion as well as effects from he magnetic field of the star itself.

In today's image, we see two contrails from airplanes that cross in the sky. Because of the positioning of the Sun and upper clouds, we also see the shadows cast by these contrails which form an X on the clouds above.

In today's image, we see a thin waning crescent moon in the sky over Mt. Etna. We also see smoke rings from the volcano - this is a rare effect that occurs only when conditions in both the volcano and the atmosphere are just right.

In today's image, we see a time-lapse video clip from the Juno spacecraft as it made its 16 close approach to the planet Jupiter. Juno has a highly elliptical orbit which allows it to come in briefly to study the planet's cloud structures, but spend most of its time well away from the intense radiation near the planet.

In today's image, we see several images of the total solar eclipse which occurred on April 8. The central page showing details of the solar corona only visible during an eclipse. The other two images show what is known as the diamond ring effect which occurs just before and after a total eclipse when only a tiny portion of the Sun is visible.

In today's image, we see the Great Carina Nebula which is a large star forming region about 7500 light years from Earth - it is much larger than the closer Orion Nebula. The bright star Eta Carinae is one expected to become a supernova at some time in the future.

In today's image, we see the spiral galaxy NGC 1232. We see this in a face-on position which gives us a great view of its spiral arms. We can see the pink color of hydrogen gas excited by the ultraviolet light from hot stars as well as the blue light from the many stars that have formed recently within those spiral arms.

In today's image, we see the total solar eclipse of April 8. Also visible in the sky and shown in this image were two planets - Venus and Mercury. Two comets can also be seen including comet Pons-Brooks which was not as bright as many had hoped.
