Spiral Galaxy NGC 6744

Image Credit & Copyright: Don Goldman

Big, beautiful spiral galaxy NGC 6744 is nearly 175,000 light-years across, larger than our own Milky Way. It lies some 30 million light-years distant in the southern constellation Pavo. We see the disk of the nearby island universe tilted towards our line of sight. Orientation and composition give a strong sense of depth to this colorful galaxy portrait that covers an area about the angular size of the full moon. This giant galaxy’s yellowish core is dominated by the light from old, cool stars. Beyond the core, spiral arms filled with young blue star clusters and pinkish star forming regions sweep past a smaller satellite galaxy at the lower left, reminiscent of the Milky Way’s satellite galaxy the Large Magellanic Cloud.

NOAA AR 2132 produced a C2.2 flare on August 7 with peak time 22:56 UT, the strongest flare in the past 24h. On the same day, NOAA AR 2135 produced a C1.4 flare around 17:28 UT. We expect more flaring at C-class level from these region and possibly also from region 2134. We maintain the warning
condition for proton activity. No earth-directed CMEs were observed. Geomagnetic conditions are quiet to unsettled. We expect a maximum K value of 3 later today and tomorrow under the possible influence of a coronal hole wind stream.

NGC 1763 in Dorado

NGC 1763 is an emission nebula in the Large Magellanic Cloud (LMC) – a small satellite to our Milky Way – about 163,000 light-years away from Earth in the constellation of Dorado. It is part of the N11 (also known as NGC 1760) star-forming region, the second largest of such in the LMC after 30 Doradus.
