Barnard 68 is a dark molecular cloud located in the constellation Ophiuchus, and is one of the coldest and most isolated places in the universe. It is approximately 500 light-years away and half a light-year across, and is likely to collapse and form a new star system. Astronomers believe that molecular clouds like Barnard 68 are potential places for new stars to form.
Comet-like plumes are blowing over the volcanic peaks of Mount Etna in this wintry mountain-and-skyscape from planet Earth. The stacked and blended combination of individual exposures recorded during the cold night of January 23, also capture naked-eye Comet ZTF just above Etna’s snowy slopes. Of course increasing sunlight and the solar wind are responsible for […]

The current darling of the northern night, Comet C/2022 E3 ZTF is captured in this telescopic image from a dark sky location at June Lake, California. Of course Comet ZTF has been growing brighter in recent days, headed for its closest approach to Earth on February 1. But this view was recorded on January 23, […]
Active galaxy NGC 1275, the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies, is a mysterious object. Wild-looking at visible wavelengths, the active galaxy is a prodigious source of x-rays and radio emission as it accretes matter from entire galaxies. This Hubble Space Telescope image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long, that are held together by magnetic fields.

To some, the dark shape looks like a mythical boogeyman. Scientifically, Lynds’ Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. In contrast, the brighter reflection nebula vdB 62 is more easily seen just above and to the right of center in […]
