NASA’s Astronomy Picture of the Day

In today's image, we see a video showing a total lunar eclipse which was visible from Tajikistan in 2011. A lunar eclipse occurs when the Moon passes into Earth's shadow and becomes dim and red. Another lunar eclipse will occur later today or tomorrow (depending on your location.)

In today's image, we see our Sun in an image taken in the light of hydrogen, converted to black and white and then inverted to give a negative image. This is then placed on a negative image of a field of stars. We se many prominences on the Sun in this image associated with heightened solar activity from 2012. We are approaching another maximum of solar activity over the next couple of years.

In today's image, we see a lunar eclipse as observed at the South Pole telescopes from May of this year. In the deepest part of the eclipse, the Moon appears a blood red color as light is bent by Earth's atmosphere into the shadow. We also see the Aurora Australis as well a part of our Milky Way galaxy.

In today's image, we see a selfie taken by the InSight lander on Mars. The mission of this lander is to study the interior of Mars through seismic waves from marsquakes. This allows us to determine what the interior must be like by the way the seismic waves travel through it. It is likely the final selfie as the solar panels are becoming caked with dust from Martian winds and will soon no longer be able to provide power to the lander.

In today's image, we see the nearby spiral galaxy known as the Triangulum Galaxy or M33. This is one of the three spiral galaxies which dominate out local group of galaxies which also includes our Milky Way and the Andromeda Galaxy.

In today's image, we see our Moon moving in front of the Sun during the recent partial eclipse. The Moon moves in front of the Sun and blocks out some of the Sun's light. We also see a solar prominence on the Sun where material has been lifted off the surface by the Sun's magnetic field and rains back down on the surface.

In today's image, we see the Lobster Nebula known for producing some of the most massive stars possible. The theoretical limit under current models is about 100 times the mass of our Sun. Stars larger than this would be unstable and would expel their outer layers to reduce their mass. Why this specific nebula produces such massive stars is a current topic of research.

In today's image, we see the Cosmic Bat Nebula, an example of a dark nebula where the material within is dense enough to block out the light so that we cannot see stars beyond. Within the nebula, new stars are forming which will eventually emerge, destroying the nebula.

In today's image, we see the spooky planet known as Earth. The clouds in the foreground are clouds of steam from vents in the ground in Iceland. The green glow in the sky is the aurora - the glow of oxygen atoms when excited by charged particles from our Sun.

In today's image, we see the dark nebula known by its catalog designation of LDN 673. This is an example of a dark nebula in which star formation is currently going on. We also see a Herbig-Haro object, also associated with young stars and cause by the outlaw of jets of material as they strike and energize material surrounding the young star.
