Universe Images

Black Sun and Inverted Starfield2012 October 15

This image of our Sun was captured originally in a very specific colour of red light, then rendered in black and white and then colour inverted. Once complete it was added to a starfield and colour inverted again. As a result we can see long filaments, dark active regions , prominences peaking around de edge and a moving

carpet of hot gas. It shows how the Sun is nearing solar maximum.

I think editing a photo helps to discover something new about our Universe because, as we see, it’s

easier to understand it this way.

A Spiral Nebula Surrounding

Star R Sculptoris 2012 October 16

This unusual spiral structure has been discovered around Milky Way star R Sculptoris, a red giant

star located about 1,500 light years away, toward the constellation of the Sculptor (Sculptoris). The

photo was taken by the new Atacama Large Millimeter/submillimeter Array (ALMA), the most

powerful telescopic array observing near millimeter wavelengths .

I find this structure incredible as the circles of the spiral are really sharp.

A quintet in the universeThis heap of galaxies placed in the constellation of Pegasus is called Stefan's Quintet. This five galaxies are as different as interesting. Two of them are in the center, almost close. They are placed to approximately 300 million light years of distance and they were photographed by the

new camera of the Hubble in 2009.It‘s interesting for me to know that five galaxies can be so close from each other, at least two of them, without joining and creating a new one.

Over 180.000 stars appear on this photo, captured by the camera of the Hubble, focusing

the centre of our galaxy, in order to find exoplanets. Planets that orbit the far-off stars

cannot be observed directly, but by means of a wide range of astronomic technologies it’s

possible to calculate its situation.Imagining there is such an amount of stars and

planets around us made me think our planet Earth is infinitely tiny.

Searching for planets

The birth of the starsIn this stellar heap called NGC 602, near the

Little Magallanes Cloud, millions of young stars issue radiation and energy as waves that erode

the material that surrounds them, creating interesting formations. The size of what this

image shows covers about 200 light years from side to side.

In my opinion, this is a beautiful image of this surprising phenomenon that sometimes take place in the universe thanks to the stars .
