If only I was there … by Foto Foosa
In a place where foxes can roam free without being hunted down by men with guns and dogs.
This view looks toward the sunlit side of the rings from about 43 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on Nov. 23, 2013 using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 752 nanometers.
The view was obtained at a distance of approximately 1.6 million miles (2.5 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 97 degrees. Image scale is 93 miles (150 kilometers) per pixel.
Star factory NGC 7538
The billowing clouds portrayed in this image from ESA’s Herschel observatory are part of NGC 7538, a stellar nursery for massive stars. Located around 9000 light-years away, this is one of the few regions of massive-star formation that are relatively close to us, allowing astronomers to investigate this process in great detail.
Star factories like NGC 7538 consist mainly of hydrogen gas, but they also contain small amounts of cosmic dust. It was through this minor – but crucial – component that Herschel could image these star-forming regions, because dust shines brightly at the far-infrared wavelengths that were probed by the observatory.
With a total mass of almost 400 000 Suns, NGC 7538 is an active factory where stars come to life – especially huge ones that are over eight times more massive than the Sun. Hundreds of seeds of future stellar generations nestle in the mixture of surrounding gas and dust scattered across the image. Once they reach a critical mass, they will ignite as stars. Thirteen of these proto-stars have masses greater than 40 Suns, and are also extremely cold, less than –250ºC.
One group of stellar seeds seem to trace a ring-like structure, visible in the left part of the image. The ring may be the edge of a bubble carved by previous stellar explosions – as stars reach the end of their lives and explode as dramatic supernovas – but astronomers are still investigating the origin of this peculiar arrangement.

The Hubble ACS image shows a portion of the southern tidal tail of the Antennae galaxies. The main visible component consists of young blue stars recently formed out of the gas accumulating along the spine of the tail, and many red background galaxies can also be seen. The region is also filled by thousands of faint red stars, just visible when zooming on the image.
The Antennae Galaxies are among the closest known merging galaxies. The two galaxies, also known as NGC 4038 and NGC 4039, started to interact a few hundred million years ago, creating one of the most impressive sights in the night sky. They are considered by scientists as the archetypal merging galaxy system and are used as a standard with which to validate theories about galaxy evolution.
By measuring the colours and brightnesses of red giant stars in the system, the scientists found that the Antennae Galaxies are much closer than previously thought: 45 million light-years instead of the previous best estimate of 65 million light-years. These red stars cannot be brighter than a certain threshold, and it is this luminosity threshold that was used to derive the new distance of the Antennae.
Do you ever stand alone out in the darkness? Have you ever felt the rest of the world drain away—all your worries and commitments and fears—and then suddenly it’s just you and the stars, face to face in the culmination of this cosmic accident of existence? And as you drink in the vast darkness and the light of far-off suns, as you realise that you are the eyes of the universe wondering at itself, you’re filled with this dizzying, soul-gripping sense of awe, because—holy shit, space.
Sirius B compared to Earth
Based on the Hubble measurements made with the Space Telescope Imaging Spectrograph, an international team found that Sirius B has a mass that is 98 percent that of our own Sun.
Despite this large mass Sirius B is only 12 000 kilometres in diameter, making it just smaller than Earth - but much denser!
Sirius B’s powerful gravitational field is 350 000 times greater than Earth’s, meaning that a 68-kilogram person would weigh 25 million kilograms standing on its surface!
ILLUMINATED CODE FROM SPACE
Bioartis Haari Tesla (behance) - "Macrocosm and microcosm is an ancient Greek Neo-Platonic schema of seeing the same patterns reproduced in all levels of the cosmos, from the largest scale (macrocosm or universe-level) all the way down to the smallest scale (microcosm or sub-sub-atomic or even metaphysical-level). In the system the midpoint is Man, who summarizes thecosmos." - I was doing some researches and I found experiment with miniatures of space so I decided to try my own. The result has been nebulae, galaxies and supernovae transformed into microorganism.
