In today's image, we see images from the recent lunar eclipse. The red and blue colors are caused by light being scattered differently by different parts of Earth's atmosphere.

In today's image, we see a large, faint nebula known in the constellation of Lacerta to the Lizard.

In today's image, we see images showing how much water there is on Earth compared to its entire size. even though we often consider Earth to be a water planet, the amount of water here is far less than one might think.

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 from much of the worlds from Europe to Africa to Asia and Australia. My podcasts are available in video form through this YouTube Channel .

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 Galaxy. My podcasts are available in video form through this YouTube Channel .

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 they are more powerful than previously thought. My podcasts are available in video form through this YouTube Channel .

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 stars in the belt of Orion.

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 Pillow Planetary Nebula is suspected to be caused by a bakery system at its center rather than a single star. My podcasts are available in video form through this YouTube Channel . This Podcast is an...

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 sky just after sunset. My podcasts are available in video form through this YouTube Channel .

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 clears its orbit of debris, which is part of the IAU planet definition. My podcasts are available in video form through this YouTube Channel .

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 such that it has the density of an atomic nucleus.

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 more atmosphere, scattering out the shorter wavelengths.

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 on the sky, this is only coincidence, based on their actual sizes and distances. My podcasts are available in video form through this YouTube Channel .

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 and Jupiter.
