Animation of the Light Echoes from Supernova 1987a - From Rolf Wahl Olsen - https://flic.kr/p/2kcAq8f
NOTE: Flickr doesn't display animated gifs, click here to view the animation on my site: www.rolfolsenastrophotography.com/Astrophotography/Light-... This image shows what I believe is the first amateur detection of light echoes from SN1987a - 33 years after the event. The light echoes are produced when the initial flash from SN1987a is subsequently reflected off interstellar dust as light travels outward from the event. Direct light from the supernova was observed on Earth in 1987, and we then see light reflected from dust in the interstellar space arriving later because it has travelled further to reach us. The animation was created by subtracting two Luminance images taken almost 8 years apart, on 24th Oct 2012 and 21st Sep 2020 respectively, in order to create a difference image which was then superimposed on a regular colour image of the area. The expanding light echoes appear as roughly circular concentric arcs, centered on SN1987a's location. This clearly shows how they have expanded during the 8 years. The echoes also appear to be moving outwards at superluminal speed: With a shift of ~47 pixels in the image, and an image resolution of 0.764"/pixel, the movement corresponds to around 28 light years at the distance of the Large Magellanig Cloud where the supernova occurred (163,000 light years away). This is clearly much faster than the speed of light given there are only 8 years between the images. This apparent superluminal speed is only an illusion though...

The empress astride the Radiant Tinged Perylion has, over several centuries, served as a symbol to the Tatran people of Tatran might and dignity.

Hubble Provides Unique Ultraviolet View of Jupiter - From NASA Marshall Space Flight Center - https://flic.kr/p/2peoZZw
This newly released image from the NASA Hubble Space Telescope shows the planet Jupiter in a color composite of ultraviolet wavelengths. Released in honor of Jupiter reaching opposition, which occurs when the planet and the Sun are in opposite sides of the sky, this view of the gas giant planet includes the iconic, massive storm called the “Great Red Spot.” Though the storm appears red to the human eye, in this ultraviolet image it appears darker because high altitude haze particles absorb light at these wavelengths. The reddish, wavy polar hazes are absorbing slightly less of this light due to differences in either particle size, composition, or altitude. The data used to create this ultraviolet image is part of a Hubble proposal that looked at Jupiter’s stealthy superstorm system. The researchers plan to map deep water clouds using the Hubble data to define 3D cloud structures in Jupiter’s atmosphere. Image Credit: NASA, ESA, and M.
