Interesting, distorted galaxy with golden ring.

Technical details at Astrobin.

Barnards in Aries:
A wide region just at the border of Taurus full of dust.

Thank you for looking!

This striking nebular profile, adjacent to the Eta Carina nebula, is shown in HST narrowband palette.

An unusual very red supernova in Centaurus A.

This week, a supernova was discovered in Centaurus A, triggering a lot of discussion and a series of Astronomers Telegrams about what type it was. It's nearby, in Centaurus A, but partially hidden by the dust that encircles the galaxy. These images were taken 24 hours after discovery, from Sydney.

Interesting. Presumably the bright star next to it is just a foreground star.

I can't make it blink.

The star next to it is indeed a foreground star. I've noticed it many times in old images of Centaurus A.

The supernova is certainly red, so it is probably quite dust-reddened.

If you click the link below to "original" then it will blink after a few moments.

Epic large pollen corona
... around the Sun

Large version: http://tavcso.hu/kep/nagykep.php?id=1005839
Well, well... spring is coming, and the first sign of that, the peanuts are blossoming. But this time, a rare and very large pollen corona vas visible afternoon. Allergic people! Brace yourselves! Pollen is coming.

What is pollen corona? You can find out at the OPOD, but its easy. The lightbeams bends through the pollen particles, create this beautiful atmosferic optic.

Observation site: Hungary, Somogy - Zselic Observatory
Time: UT 15:00~

The Lone Ear … Really?
Copyright: Petr Horálek
So many object of "close" and distant Universe in the sky and the reflection of the the Swedish-ESO Submilimetre Telescope at the southern part of the large complex of La Silla Observatory. More (and images in higher dimension): http://www.astronom.cz/horalek/?p=2174

The galactic shot
Copyright: Petr Horálek
The dome of the Very Large Telescope (VLT) of the ESO’s Paranal observatory is hiding one of the most scientifically productive instrument of the world. Pointing it’s powerful beam in the sky, it feels like the astronomers are somehow trying to communicate with potential extraterrestrial forms of life. But no, this beam has another, very sophisticated purpose. The so-called Laser Guide Star (LGS) is part of the VLT’s adaptive optics system and is used as a reference to correct the blurring effect of the atmosphere on images. But apart from this, the image gives opportunity to enjoy one more significant object in such a deep detail. One of the most majestic part of the southern sky, the Large Magellanic Cloud (LMC), is in this wild scene. This irregular galaxy belongs to the Milky Way as its satellite, located about 160 000 light years from the the Sun. Even if it’s not a pretty typical and completely „grown up“ galaxy, it gives a view to some particular structures as bar in its center. In fact, it’s structure suggests that it may have previously been a standard barred spiral galaxy before being disrupted, likely by the gravitational tug of the Milky Way, resulting in the disruption of its spiral arms. The LMC’s present irregular appearance is likely the result of tidal interactions with both the Milky Way and the Small Magellanic Cloud (SMC). The pink-red regions are created of emission hydrogen nebulae, full of material for producing new stars. One of the most spectacular region is the Tarantula Nebula (the brightest object in the LMC), which is apparently the most active star-forming region.

Resting VLT and airglow „ribs“

Airglow "ribs" over the "resting" dome of one VLT telescope during cloudiness moment. In the same direction of those structures a few hours later were captured the red as told in ESOcast. More (ESOcast and the image in higher dimension): http://www.astronom.cz/horalek/?p=1963
