The subject of this NASA/ESA Hubble Space Telescope Picture of the Week is NGC 1637, a spiral galaxy located 38 million light-years from Earth in the constellation Eridanus.
This image comes from an observing programme dedicated to studying star formation in nearby galaxies. Stars form in cold, dusty gas clouds that collapse under their own gravity. As young stars grow, they heat their nurseries through starlight, winds, and powerful outflows. Together, these factors play a role in controlling the rate at which future generations of stars form.
Evidence of star formation is scattered all around NGC 1637, if you know where to look. The galaxy’s spiral arms are dotted with what appear to be pink clouds, many of which are accompanied by bright blue stars. The pinkish colour comes from hydrogen atoms that have been excited by ultraviolet light from young, massive stars. This contrasts with the warm yellow glow of the galaxy’s centre, which is home to a densely packed collection of older, redder stars.
The stars that set their birthplaces aglow are comparatively short-lived, and many of these stars will explode as supernovae just a few million years after they’re born. In 1999, NGC 1637 played host to a supernova, pithily named SN 1999EM, that was lauded as the brightest supernova seen that year. When a massive star expires as a supernova, the explosion outshines its entire home galaxy for a short time. While a supernova marks the end of a star’s life, it can also jump start the formation of new stars by compressing nearby clouds of gas, beginning the stellar lifecycle anew.
[Image Description: A spiral galaxy filling the view. Its disc is filled with bright red spots where stars are forming, dark reddish threads of dust that obscure light, and bluish glowing areas where older stars are concentrated. It has a large, glowing yellow oval area at the centre, from which two spiral arms wind through the galaxy’s disc. The bottom side of the disc is rounded while the top side is somewhat squared-off.]

The swirls of the galaxy IC 1776 stand in splendid isolation in this image from the NASA/ESA Hubble Space Telescope. This galaxy lies over 150 million light-years from Earth in the constellation Pisces.
IC 1776 recently played host to a catastrophically violent explosion — a supernova — which was discovered in 2015 by the Lick Observatory Supernova Search, a robotic telescope which scours the night sky in search of transient phenomena such as supernovae. A network of automatic robotic telescopes are spread across the globe, operated by both professional and amateur astronomers, and, without human intervention, reveal short-lived astronomical phenomena such as wandering asteroids, gravitational microlensing, or supernovae.
Hubble investigated the aftermath of the supernova SN 2015ap during two different observing programmes, both designed to comb through the debris left by supernovae explosions in order to better understand these energetic events. A variety of telescopes automatically follow up the detection of supernovae to obtain early measurements of these events’ brightnesses and spectra. Complementing these measurements with later observations which reveal the lingering energy of supernovae can shed light on the systems which gave rise to these cosmic cataclysms in the first place.
[Image description: A spiral galaxy. It is irregularly-shaped and its spiral arms are difficult to distinguish. The edges are faint and the core has a pale yellow glow. It is dotted with small, wispy, blue regions where stars are forming. A few stars and small galaxies in warm colours are visible around it.]

Every street has paper lanterns, some more than others. These were on one of the side streets near Senso-Ji.

Another of my Thanksgiving Day dramatic sky shots from Fort Ross, with the Pacific and the wooden Russian Church silhouetted on the left, more of the Russian fort complex silhouetted to the right of these. It really was a fabulous sunset. This fort would have been in full use by the Russians during the war of 1812, which is the war that is the backdrop to Tolstoy's War and Peace.

It is definitely the weather for our wood burning stove.
The BBC weather says it will be minus 7 tonight which is very cold for us.
This image features a relatively small galaxy known as UGC 5189A, which is located about 150 million light-years away in the constellation Leo. This galaxy was observed by Hubble to study a supernova explosion in 2010 known as SN 2010jl. This particular supernova was notable for having been an exceptionally luminous supernova event. In fact, over a period of three years, SN 2010jl released at least 2.5 billion times more visible energy alone than our Sun emitted over the same timeframe across all wavelengths.
Even after supernovae have faded to non-observable levels, it can still be of interest to study the environments where they occurred. This can provide astronomers with valuable information: supernovae can take place for a variety of reasons, and understanding the environments in which they took place can help improve our understanding of the conditions necessary for them to be triggered. Furthermore, follow-up studies after supernovae can improve our understanding of the immediate aftermath of such events, from their potent effects on the gas and dust around them, to the stellar remnants they leave behind.
To this end, UGC 5189A has been observed many times by Hubble since 2010. This image is from data collected in three of the latest Hubble studies of UGC 5189A, which also examined several other relatively nearby galaxies that recently hosted supernovae — ‘relatively nearby’, in this context, meaning roughly 100 million light years away.
[Image Description: A galaxy that is flat and misshapen. Above and on its right it is covered by plumes of shining gas and dust, while its centre and left side are more dim and patchy. A trail of dark, dim dust stretches from below the galaxy up and off to the left, where there are three more bright patches. The background around the galaxy is quite dark, with only a few small background galaxies and one star visible.]

Sometimes you just have to change perspective. THese beauties were growing in northern New Medico along the upper Pecos river.
Drents-Friese Wold National Park
On the border of the provinces of Friesland and Drenthe lies Drents-Friese Wold National Park. Within this extensive area of woodland and heath lie the shifting sands of Aekingerzand.
Het Nationaal Park Drents-Friese Wold is een natuurgebied op de grens van de Nederlandse provincies Friesland en Drenthe. Het Nationale Park bestaat uit bos, heide en stuifzanden. Het is vooral bekend vanwege De Kale duinen (het Aekingerzand). Dit stuifzandgebied is groot genoeg om de wind de kans te geven het zand ook echt te laten stuiven. Met behulp van grazers wordt het gebied verder vrij van gras en bomen gehouden.
