Horsehead sculpted in dust

From Hubblecast, the unveiling of Hubble’s 23rd Anniversary image: a stunning new image of one of the most distinctive objects in our skies: the Horsehead Nebula. This image shows the nebula in a whole new light, capturing plumes of gas in the infrared and revealing a beautiful, delicate structure that is normally obscured by dust.

Hypnotic solar explosions in 4k

To the naked eye, our sun is an unremarkable ball of heat and light. Under the eye of the Solar Dynamics Observatory, or S.D.O, the Sun’s activity is revealed under various spectrums of light....

MWC 922: The Red Square Nebula

What could cause a nebula to appear square? No one is quite sure. The hot star system known as MWC 922, however, appears to be embedded in a nebula with just such a shape. The above image combines infrared exposures from the Hale Telescope on Mt. Palomar in California, and the Keck-2 Telescope on Mauna Kea in Hawaii.

NGC 5189: An unusually complex planetary Nebula

Why is this nebula so complex? When a star like our Sun is dying, it will cast off its outer layers, usually into a simple overall shape. Sometimes this shape is a sphere, sometimes a double lobe, and sometimes a ring or a helix. In the case of planetary nebula NGC 5189, however, no such simple structure has emerged.
