Ett fönster till rymden
När jordens alla vassa problem känns jobbiga på huden så är det ibland skönt att rikta blicken mot rymden.
Dess oändlighet får mig konstigt nog att känna mark under fötterna och påminner mig om att problemen vi ibland tvingas tampas med inte är så stora när allt kommer omkring.
Jag är verkligen tacksam för att vår vän Micke Palm också tycker om att vända blicken mot himlen.
När han vänder näsan mot oändligheten har han dessutom med sig ett högkvalitativt teleskop som han tar foton med.
Men, inte nog med att han tar vackra och professionella foton - han delar med sig av dem.
Tack!
Rosett nebulosan kallas ibland för skall(e)nebulosan eftersom den liknar en dödskalle i vissa vinklar vilket orsakas av 'pareidolia', det vill säga att hjärnan uppfattar bekanta mönster i luddiga former.
Den är formad av unga stjärnor som producerar intensiv strålning och stjärnvindar.
Nebulosan har en diameter på över 100 ljusår och ligger cirka 5 000 ljusår bort i stjärnbilden Enhörningen.
Den har en 'Wrench Trunk' som är en ovanligt formad gaspelare skapad av ett magnetfält.
Magiskt.
When all the pressing problems of the world weigh heavily....
.... on your mind, it can sometimes be nice to turn your gaze towards space.
Strangely enough, its infinity makes me feel grounded and reminds me that the problems we sometimes have to deal with are not so big after all.
I am truly grateful that our friend Micke Palm also enjoys looking up at the sky.
When he turns his gaze towards infinity, he also brings a high-quality telescope with him, which he uses to take photos.
But not only does he take beautiful, professional photos – he also shares them.
Thank you!
The third largest spiral galaxy in the Andromeda galaxy, which is embedded in the Milky Way, is the Triangulum Galaxy [Messier], which is located about three million light years from Earth and contains approximately 40 billion stars and is 60,000 light years in diameter – just a little thing like that.
You can actually see it with the naked eye, even though it mostly looks like a diffuse fluff.
It is best known for forming stars at a dizzying speed.
The Heart Nebula of glowing hydrogen gas is shaped like a heart and is 200 light years wide. It is an emission nebula in Cassiopeia, located approximately 7,500 light years away from our little planet.
The nebula is a teenager compared to the sun.
The glow and energy radiating from the nebula comes from a group of young, dense stars called Melotte 15 via ions that encounter gases.
The nebula was discovered in 1787 by Sir William Herschel, a British astronomer from Germany who had already discovered the planet Uranus in 1781 and was appointed Royal Astronomer by King George III.
The Heart Nebula is linked to the Soul Nebula (top) by a small gas bridge.
Micke also managed to find the Manet Nebula, which is a supernova remnant located 5,000 light years away in the constellation Gemini.
The Jellyfish Nebula was created after a huge stellar explosion that killed the star about 30,000 years ago and is exciting because it teaches us about cosmic evolution. What we see on the outside are layers of shock waves eagerly playing with the gas and dust that surround it.
The explosion itself also formed iron, gold and calcium, which are important for the birth of new stars and planets.
An absolutely stunning photo of the Andromeda Galaxy, which is the closest galaxy to Earth that we know of (2.5 million light years)! As I read up on it, I see that it is on a collision course with our own Milky Way and that the two galaxies will probably merge in 4.5 billion years.
We can see the galaxy from Earth, albeit very faintly.
In the centre of Andromeda is a supermassive black hole and a so-called massive star cluster.
We have about 50 galaxies around us, and the Triangulum Galaxy is the third largest. It is a satellite galaxy orbiting the larger Andromeda Galaxy.
Being a satellite to a galaxy can be described as a cosmic dance in which the galaxy orbits the Andromeda Galaxy in spiral movements.
Stars are also actively and relatively frequently formed in this galaxy.
The Horsehead Nebula, located in the constellation Orion, is difficult to find. It is a dark, dense dust cloud that reveals its unique shape by blocking the light from a more distant, glowing red nebula.
It is described as a work of art “sculpted” by the powerful ultraviolet radiation from nearby stars, such as the bright star Sigma Orionis.
The Whirlpool Galaxy (spiral galaxy) was discovered by Charles Messier in 1773. It is the first galaxy to be
classified as a spiral and is known for its elegant, curved arms that give it high speed.
The Whirlpool Galaxy dances a “cosmic couple dance” with a galaxy that has been given the personal name NGC5195. They will soon be married.
The nebula, named after California, is a huge cloud of gas and dust that gets its red hydrogen glow from a nearby star, Xi Persei. The nebula spans about 100 light-years and is located in
Orion's arm of the Milky Way (about 1,000 to 1,500 light-years from Earth).
I sometimes look for the constellation Perseus and the Pleiades star cluster in the pitch-black sky, and this nebula is located in Perseus, close to the Pleiades.
Many galaxies have black holes at their centre, but not the Triangulum Galaxy, which is a “disk galaxy”. It is flat, which is unusual for a large spiral galaxy and makes it unique – or as unique as it can be with our limited knowledge.
The Triangulum Galaxy is seen as a cousin to our own Milky Way galaxy and is also known for producing many stars.
This galaxy is on its way to merging with Andromeda in about 2.5 billion years.
The Rosette Nebula is sometimes called the Skull Nebula because it resembles a skull from certain angles, which is caused by “pareidolia”, i.e. the brain perceiving familiar patterns in fuzzy shapes.
It is formed by young stars that produce intense radiation and stellar winds.
The nebula has a diameter of over 100 light years and is located about 5,000 light years away in the constellation Unicorn.
It has a “Wrench Trunk”, which is an unusually shaped gas column created by a magnetic field.
Magical.
When it comes to more down-to-earth activities, I just saw that I have been given a slot at Culture Night on 13 September from 12:00 to 15:00, where I will be selling books near the Uppsala Writers' Society's premises at Walmstedtska on Sysslomansgatan 1 – looking forward to it!
