NASA’s Astronomy Picture of the Day

In today's image, we see an image of the surface of Mars taken by the Perseverance Rover which has been exploring Mars since 2021. We can note the similarities to many desert areas on Earth with the exception that there is no sign of life.

In today's image, we see an image of comet Pons-Brooks which made its closest approach to Earth a couple of days ago and is heading back into the outer solar system We can see the two distinct tails - the ion tail pointing downward to the left and the dust tail toward the upper left, less distinct and more spread out.

In today's image, we see the spiral galaxy known as NGC 2403. This is a galaxy much like our own Milky Way in many ways and shows the distinct blue in the spiral arms from bright stars that have recently formed. We also see the pink color if ionized hydrogen (H II) regions.

In today's image, we see the Moon in a short video put together from images taken by the Lunar Reconnaissance Orbiter (LRO). This shows the near side of the Moon which always faces Earth, but also the far side which cannot be seen from the surface of Earth and has only been studied since the late 1950s.

In today's image, we see one of the moons of Saturn, Helene in a 3D image which can be viewed with the red-blue 3D glasses. This moon orbits in a Lagrange point formed by the gravitation of Saturn and one of the other moons, Dione.

In today's image, we see the region around the Wolf-Rayet star, WR 134. A Wolf-Rayet star is the type of star that is expected to become a supernova at the end of its short life. At that point, it will explode, sending heavier elements out into the universe to enrich the material from which future stars will form.

In today's image, we see the Eiffel Tower in the foreground and the Moon above in the sky. Around the Moon, we see a lunar corona - this is a quantum mechanical effect caused by many rain drops which all have a similar size and each color of light by a different amount.

In today's image, we see a stairway leading up a mountain and apparently to the Milky Way in the sky! Of course, the Milky Way is far beyond anything here on Earth, but this does give us a striking view. In the sky, we see the stars Vega and Altair as well as the airglow near the horizon.

In today's image, we see an image from the Solar Dynamics Observatory showing the rotation of our Sun over the course of a day. Here were see the active region, AS 3446 as it returns around the limb of the Sun and gives off a powerful X-class flare. Over the coming days, it will move into better view and further eruptions will have the possibility of impacting Earth causing communication disruptions and more strong aurorae.

In today's image, we see the Chameleon I Molecular Cloud which is a region of star formation visible in the southern sky. Here we see a number of dark nebulae as well as a couple of reflection nebulae which are both associated with regions of newly forming stars.
