Space

I love all things in our universe, but I especially love the camera work done outside of our atmosphere. Impress me with shots of things you enjoy about space and I promise to give you the appropriate ooohs and ahhhhs..... I came across this one during my flip through Imgur today. I love how it captures the delicacy of Mars' thin atmosphere and the refraction and amplification of the sun's rays upon the surface of the planet. *sigh*

Maybe we can make this thread just to share pictures of Space.

Might be a cliche image but this one picture means everything to me and I don't think I can come close to how Carl Sagan described it:

He was and still is a very missed mind. He had a way of describing the impossible and making it practical. He was also kind to those who differed in opinions, and we all know how rare that is these days.

:rose:

And I love the BLUE MARBLE shot!!! :love:

Some additional info on that from esa.int.

This luminous star, AG Carinae, is losing mass at a phenomenal rate. Its powerful winds reach up to seven million km/hour, and exert enormous pressure on the clouds of material already expelled by the star.

These incredible winds have already cleared a region immediately around the star, and sculpted the material further away into the pattern observed in this Hubble Space Telescope image.

AG Carinae is a rare breed of Luminous Blue Variable star that evolved from a star around 50 times the mass of our Sun. They show variable and unpredictable behaviour, experiencing periods of quiescence and outbursts alike. They are also some of the most luminous stars known: tens of thousands to several million times as luminous as the Sun.

It is worth noting that the bright glare at the centre of the image is not the star itself, which is tiny at this scale and hidden within the saturated region. The white cross is also not an astronomical phenomenon but rather an effect of the telescope.

AG Carinae lies 20 000 light-years away in the constellation of Carina. The image was taken with the Hubble’s Wide Field and Planetary Camera 2, and was first released in September 2014.

Images from Nasa’s Cassini spacecraft – the most detailed pictures ever taken of Saturn’s rings – showed many previously unseen features, including millions of possible “moonlets”.

I just wanna add that a lot of the 'mind-blowing' pictures we have of stars and planets are artist rendering and not a true image of the actual objects, we just color them going by the chemicals found in them and each color represents different material then the artist adds a lot of vibrance and other effect to make the planet or star look breath taking.

February brought extremely exciting news: the thrilling discovery of seven Earth-sized planets found orbiting the nearby Trappist-1 star, raising hope that the hunt for alien life beyond the solar system can start much sooner than previously thought. This artist’s concept shows what the planetary system may look like, based on available data about the planets’ diameters, masses and distances from the host star.

February also saw the release of this spectacular image from the VLT Survey Telescope, showing the Cat’s Paw Nebula (upper right) and the Lobster Nebula (lower left). These are regions of active star formation where the hot young stars are causing the surrounding hydrogen gas to glow red. The very rich field of view also includes dark clouds of dust. With around two billion pixels this is one of the largest images ever released by ESO. Note that the circular features in the image around bright stars are not real; they are due to reflections within the optics of the telescope and camera.

This image shows the positions of two million stars in our galaxy, based on data from the Tycho-Gaia Astrometric Solution – one of the products of the first Gaia data release. The stars are plotted in galactic coordinates and using a rectangular projection: in this, the plane of the Milky Way stands out as the horizontal band with greater density of stars. The shape of the Orion constellation can be spotted towards the right edge of the frame.

In May, Nasa’s Juno probe captured its dramatic first close-up images of Jupiter, revealing giant, chaotic weather systems and giving new measurements that will help build unprecedented map of planet’s interior. This image is of Jupiter’s south pole, as seen by the spacecraft from an altitude of 32,000 miles (52,000 kilometres). The oval features are cyclones, up to 600 miles (1,000 kilometres) in diameter.

In May, astronomers produced a highly detailed image of the Crab Nebula, by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum. This image combines data from five different telescopes: The VLA (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-ray Observatory (X-ray) in purple. The Crab Nebula, the result of a bright supernova explosion seen by Chinese and other astronomers in the year 1054, is 6,500 light-years from Earth.

Using ESO’s Very Large Telescope Interferometer astronomers constructed this remarkable image of the red supergiant star Antares – the most detailed image ever of this object, or any other star apart from the sun.

One of the most exciting space stories this year was the detection in October of a mysterious object detected hurtling past our sun, which was confirmed to be an asteroid visitor from another solar system. Named ‘Oumuamua, it was even examined for evidence of alien technology.

At a distance of just 160 000 light-years, the Large Magellanic Cloud is one of the Milky Way’s closest neighbours. It is home to one of the largest and most intense regions of active star formation known to exist in our galactic neighbourhood: the Tarantula Nebula. This Nasa/Esa Hubble Space Telescope image shows both the spindly, spidery filaments of gas that inspired the region’s name, and the intriguing structure of stacked “bubbles” that forms the so-called Honeycomb Nebula (to the lower left).

In September, the Cassini spacecraft ended its mission with a dramatic plunge into Saturn’s atmosphere. In December, this image, composed of a series of pictures snapped during Cassini’s last look at the planet , was released. Showing Saturn and its main rings, the moons Prometheus, Pandora, Janus, Epimetheus, Mimas and Enceladus also make a faint appearance in the background.
