See the fantastic space photos from Rymdstyrelsen's (the Swedish Space Agency's astrophoto competition at Curiosum!
The Rymdstyrelsen's astrophoto competition has been decided! Among all the fantastic photos, five top winners were selected, whose contributions you can see at Curiosum during the summer, along with descriptions of how the photos were taken (in Swedish).
More photos can be found at Rymdstyrelsen.
The sun by Peter Rosén
The picture was taken from a roof terrace at Kungsholmen in Stockholm.
The sun is 150 million kilometers from the earth and the light takes 8.23 minutes to reach us. It is the source of all life and the most important celestial body in the universe for us.
The sun begins to come out of its minima, which is a period of low activity in the sun's 11-year cycle. The activity on the surface is still relatively low but several nice protuberances can be seen as flames all the way around the edge.
Protuberances are huge gas and plasma clouds caused by the sun's strong magnetic field. When ejected from the sun's surface, they can reach thousands of kilometers into space before either falling back on the sun's surface or being released and dissolved.
The supermoon is photographed by Linus Gamni.
The descending supermoon in its peak photographed in symmetrical harmony with its reflection and two sleeping swans.
A supermoon can be seen when a full moon or new moon occurs when the moon is closest to the earth. A supermoon occurs approximately every fourteen full moons when the sun, earth and moon are in line while the moon is as close as it can be to the earth.
The North American Nebula by Zoltan Nagy.
The North American nebula is an emission nebula in the zodiac sign Swan. Emission nebulae are clouds of ionized gas that glow with their own light. Inside the cloud, lots of new stars are created.
The nebula is named after its shape similar to the continent of North America, complete with the Gulf of Mexico. Nebulosa is a cloud of gas and space dust several light-years large. Emission nebulae are normally large formations consisting mainly of ionized hydrogen.
These nebulae are the birthplace of new stars. Young stars in emission nebulae excite the surrounding gas to illuminate. This makes emission nebulae very easy to see, they usually have a reddish color due to the hydrogen. If other substances also exist, this can give rise to colorful objects.
A starry cave by Teddy Svenneskog.
The clear line of stars you can see in the sky where it is really dark is called the Milky Way band. They are seen as a diffuse bright line that stretches across the entire sky, through, among other things, the constellations the Swan, Cassiopeia, Perseus, and in the direction of Sagittarius.
The picture was taken at Munkkyrkan in Grebbestad, The cave, which is located by the sea, is 11-12 meters deep and is a formation that remains from the ice age. Outside we see the Milky Way. It is estimated that there are 200-400 billion stars in the Milky Way.
The Heart Nebula by Arvid Emtegren.
The cardiac nebula, or IC 1805, is an emission nebula in the constellation Cassiopeja, located at a distance of 7,500 light-years from Earth. Nebulae are giant clouds of gas and space dust from which stars are born.
In the upper right of the picture you can also see the small oval planetary nebula WeBo 1 in blue tones. Arvid Emtegren has been photographing space since 2019 and this picture was taken during three cold January nights in Sundsvall 2021 through a telescope.
