NASA’s Astronomy Picture of the Day

In today's image, we see a sunset from Sardinia in an image taken last month. When the moon is full, it will rise as the sun sets which will happen tomorrow. This will also be a lunar eclipse visible…

In today's image, we see the globular star cluster known as 47 Tuc. This is a prominent star cluster visible in the souther hemisphere and the second brightest globular star cluster as seen from Eart…

In today's image, we see the spiral galaxy known as NGC 4565. This is a spiral galaxy seen edge-on from Earth. We can see the thin disk of the galaxy, giving it a more popular nickname of the Needle …

In today's image, we see recently studied jets within the Africa Nebula around the neutron star - the x-ray source of Cir X-1. New studies show that the jets form early after the supernova and that t…

In today's image, we see the dark nebula known as the Horsehead nebula off to the right. To the left we see the Flame Nebula and at the top of the image, the bright star Alnitak, only of the bright s…

In today's image, we see one of the large moons of Jupiter - Callisto. this is one of the large moons of the solar system, which shows cratering on its icy surface.

In today's image, we see what is known as the Pillow Planetary Nebula. This type of nebula forms when a star like our Sun reaches the end of its life and sheds its outer layers. The complexity of the…

In today's image, we see the very young crescent moon - only 1.5 days old and only 2% of the visible face of the Moon illuminated. This is a waxing crescent moon, which would be seen in the western s…

In today's image, we see a long, dark nebula stretching across a red emission nebula in the constellation of Ophiuchus.

In today's image, we see an image that shows a number of galaxies, stars within our own Milky Way galaxy, and dust clouds known as the galactic cirrus, which are a part of our Milky Way.

In today's image, we see an image of an exoplanet which is in the process of carving out a gap in the disk of material around the star from which it formed. We can think of this as how a planet clear…

In today's image, we see a 3-second timelapse of a solar prominence as we watch solar material fall back onto the solar surface.

In today's image, we see the central regions of the Crab Nebula showing the pulsar located at the center. A pulsar is a rapidly spinning neutron star - which is a star pressed together by gravity suc…

In today's image, we see our Moon apparently caught in a fishing net in this image. The red color of the Moon is because of the fact that it is close to the horizon and the light has to pass through …

In today's image, we see two nebulae: M57 also known as the Ring Nebula and IC 1296, a spiral galaxy - known as a spiral nebula until just about 100 years ago. While they appear roughly the same size…

In today's image, we see large number of Perseid meteors from the recent shower. This composite of about 500 images shows many Perseids, as well as a couple of sporadic meteors and the planets Venus …

In today's image, we see a number of Perseid meteors captured in various images and combined together in one picture.

In today's image, we see the galaxy known as NGC 1309. This galaxy is said to be useful since there have been multiple supernovae as well as Cepheid variable stars known in it. This gives us multiple…
