Sail of stars
The spiral arms of the galaxy NGC 3318 are lazily draped across this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies in the constellation Vela and is roughly 115 light-years away from Earth. Vela was originally part of a far larger constellation, known as Argo Navis after the fabled ship Argo from Greek mythology, but this unwieldy constellation proved to be impractically large. Argo Navis was split into three separate parts called Carnina, Puppis, and Vela — each named after part of the Argo. As befits a galaxy in a nautically inspired constellation, the outer edges of NGC 3318 almost resemble a ship’s sails billowing in a gentle breeze.
Despite its placid appearance, NGC 3318 has played host to a spectacularly violent astronomical phenomenon, a titanic supernova first detected by an amateur astronomer in 2000. Thanks to NGC 3318’s distance from Earth, the original supernova must have taken place in or around 1885. Coincidentally, this was the year in which the only supernova ever to be detected in our neighbouring galaxy Andromeda was witnessed by 19th-century astronomers.

Mini-jet found near milky way’s supermassive black hole
Hubble has found circumstantial evidence that the black hole is still smoldering long after the earlier outburst. Hubble astronomers' evidence is like doing an archeological dig to try and peer through the interstellar pollution of dense sheets of dust and gas between Earth and the galactic center, 27,000 light-years away. Hubble photographed a bright knot of gas that has been impacted by an invisible jet from the black hole, that is merely 15 light-years from it. The black hole must have shown brilliantly billions of years ago as a quasar (quasi-stellar object), when our young galaxy was feeding on lots of infalling gas. But after all this time the black hole still goes through fits and starts, and is not ready for napping as long as there is a snack around.
This image presents a composite view of X-rays, molecular gas, and warm ionized gas near the galactic center. The graphic of a translucent, vertical white fan is added to show the suggested axis of a mini-jet from the supermassive black hole at the galaxy’s heart. The orange-colored features are of glowing hydrogen gas. One such feature, at the top tip of the jet is interpreted as a hydrogen cloud that has been hit by the outflowing jet. The jet scatters off the cloud into tendrils that flow northward. Farther down near the black hole are X-ray observations of superheated gas colored blue and molecular gas in green. These data are evidence that the black hole occasionally accretes stars or gas clouds, and ejects some of the superheated material along its spin axis.

Hubble finds a black hole igniting star formation in a dwarf galaxy
Black holes are often described as the monsters of the universe—tearing apart stars, consuming anything that comes too close, and holding light captive. Detailed evidence from the NASA/ESA Hubble Space Telescope, however, shows a black hole in a new light: fostering, rather than suppressing, star formation. Hubble imaging and spectroscopy of the dwarf starburst galaxy Henize 2-10 clearly show a gas outflow stretching from the black hole to a bright star birth region like an umbilical cord, triggering the already dense cloud into forming clusters of stars. Astronomers have previously debated that a dwarf galaxy could have a black hole analogous to the supermassive black holes in larger galaxies. Further study of dwarf galaxies, which have remained small over cosmic time, may shed light on the question of how the first seeds of supermassive black holes formed and evolved over the history of the universe.
This dwarf starburst galaxy Henize 2-10 sparkles with young stars in this Hubble visible-light image. The bright region at the center, surrounded by pink clouds and dark dust lanes, indicates the location of the galaxy's massive black hole and active stellar nurseries.

One of a pair
In this image the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, more than 50 million light-years from Earth. This galaxy is one of a pair, but NGC 1317’s rowdy larger neighbour NGC 1316 lies outside Hubble’s field of view. Despite the absence here of its neighbouring galaxy, NGC 1317 is accompanied in this image by two objects from very different parts of the Universe. The bright point ringed with a criss-cross pattern is a star from our own galaxy surrounded by diffraction spikes, whereas the redder elongated smudge is a distant galaxy lying far beyond NGC 1317. The data presented in this image are from a vast observing campaign of hundreds of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. Combined with data from the ALMA array in the Atacama desert, these observations help astronomers chart the connections between vast clouds of cold gas and the fiercely hot young stars that form within them. ALMA’s unparalleled sensitivity at long wavelengths identified vast reservoirs of cold gas throughout the local Universe, and Hubble’s sharp vision pinpointed clusters of young stars, as well as measuring their ages and masses. Often the most exciting astronomical discoveries require this kind of telescope teamwork, with cutting-edge facilities working together and providing astronomers with information across the electromagnetic spectrum. The same applies to future telescopes, with Hubble’s observations laying the groundwork for future science with the NASA/ESA/CSA James Webb Space Telescope.

Four filter fusion
This stellar whirlpool is a spiral galaxy named NCG 7329, which has been imaged by Hubble’s Wide Field Camera 3 (WFC3). Creating a colourful image such as this one using a telescope such as Hubble is not as straightforward as pointing and clicking a camera. Commercial cameras will typically try to collect as much light of all visible wavelengths as they can, in order to create the most vibrant images possible. In contrast, raw images collected by Hubble are always monochromatic, because astronomers typically want to capture very specific ranges of wavelengths of light at any time, in order to do the best, most accurate science possible. In order to control which wavelengths of light will be collected, Hubble’s cameras are equipped with a wide variety of filters, which only allow certain wavelengths of light to reach the cameras’ CCDs (a CCD is a camera’s light sensor — phone cameras also have CCDs!).
How are the colourful Hubble images possible given that the raw Hubble images are monochromatic? This is accomplished by combining multiple different observations of the same object, obtained using different filters. This image, for example, was processed from Hubble observations made using four different filters, each of which spans a different region of the light spectrum, from the ultraviolet to optical and infrared. Specialised image processors and artists can make informed judgements about which optical colours best correspond to each filter used. They can then colour the images taken using that filter accordingly. Finally, the images taken with different filters are stacked together, and voila! The colourful image of a distant galaxy is complete, with colours as representative of reality as possible.

NGC 4254 is a grand-design spiral galaxy located approximately 45 million light-years from Earth in the constellation Coma Berenices. The image is a combination of observations conducted at different wavelengths of light to map stellar populations and warm gas. The golden glows mainly correspond to clouds of ionised hydrogen, oxygen and sulphur gas, marking the presence of newly born stars, while the bluish regions in the background reveal the distribution of slightly older stars. The image was taken as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) project, which is making high-resolution observations of nearby galaxies with telescopes operating across the electromagnetic spectrum.
A team of astronomers has released new observations of nearby galaxies that resemble colourful cosmic fireworks. The images, obtained with the European Southern Observatory’s Very Large Telescope (ESO’s VLT), show different components of the galaxies in distinct colours, allowing astronomers to pinpoint the locations of young stars and the gas they warm up around them. By combining these new observations with data from the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, the team is helping shed new light on what triggers gas to form stars.
Astronomers know that stars are born in clouds of gas, but what sets off star formation, and how galaxies as a whole play into it, remains a mystery.

To understand this process, a team of researchers has observed various nearby galaxies with powerful telescopes on the ground and in space, scanning the different galactic regions involved in stellar births.
“For the first time we are resolving individual units of star formation over a wide range of locations and environments in a sample that well represents the

ESA to build second deep space dish in Australia
ESAÕs solar-powered giant one year on.
ESAÕs 35-metre antenna in Australia has now been powered by the Sun for over a year, cutting costs and reducing carbon emissions by 330 tonnes - equivalent to 1.9 million km driven by car.
The solar plant at the New Norcia station in Western Australia started its first full month catching solar rays in August 2017. One year later, it had produced 470 Megawatt-hours of power Ð enough to supply 120 four-person homes for a year, fuelling 34% of the total electricity consumption of the station.
In order for the tracking station to be powered 100% by renewable energy, more panels would be required. Other sources of energy could also be used such as kite power, hydrogen or geothermal energy.
ÒI am really happy with these results Ð they reach beyond our initial expectations when we began the solar-power upgrade and I would be thrilled to see the same development spread to our other ground stations,Ó explains Marc Roubert, ESA's ground stations maintenance engineer.
With this success, ESA engineers will investigate possible similar upgrades for other stations.
Ultimately, Marc says, it would be a real achievement to get all ESA ground stations in the Estrack network completely off the mains power grid. This way, they can continue to track and communicate with satellites orbiting Earth and in deep space, while reducing the carbon footprint of the AgencyÕs giant 'eyes on the skies'.Credit: ESA / eyevine

Description
ESA's 35-metre radio antenna in Malargüe, Argentina, has had a major refurbishment. Extenstive modifications made will now allow the ESTRACK network to support future mission like Euclid, launching in 2022, and to transfer data at much higher rates.
Upgrades to the ESA Malargüe station, and similar upgrades carried out in the Cebreros station located in Spain in 2017, make a big difference to deep space missions.
Currently missions like Gaia are able to send back data at a channel rate of 10Mb/s. Euclid will send back data at a rate of 149Mb/s – a similar increase in speed as we have experienced in our internet browsing in the last 10 years.
Euclid, which will orbit at the Lagrange point L2, will be fitted with the 26 GHz band radio giving it a higher bandwidth for transferring data to and from Earth, significantly increasing the scientific information returned over time.
The refurbishment of Cebreros and Malargue stations, will allow ESA deep space antennas to receive broadband signals at 26GHz as well as the conventional X-band frequency.Credit: ESA / eyevine

NEWS - ExoMars: 'Schiaparelli' schweigt
On 10 October, ESA’s deep-space radio dish in Cebreros, Spain, transmitted an 866 sec interstellar message towards the North Star as part of the international “A Simple Response” project.
This 30 sec exposure was taken just as the 35 m-diameter dish completed rotating from pointing at the the North Star back to the vertical parked position.
This week and next, the Cebreros antenna will play a crucial role in the arrival of ESA’s ExoMars orbiter and lander at the Red Planet, set for 19 October. It will communicate with both the ExoMars Trace Gas Orbiter and the older Mars Express.

Mars navigation
In order to precisely deliver the Schiaparelli landing demonstrator module to the martian surface and then insert ExoMars/TGO into orbit around the Red Planet, it’s necessary to pin down the spacecraft’s location to within just a few hundred metres at a distance of more than 150 million km. To achieve this amazing level of accuracy, ESA experts are making use of ‘quasars’ – the most luminous objects in the Universe – as ‘calibrators’ in a technique known as Delta-Differential One-Way Ranging, or delta-DOR. Until recently, quasars were only poorly understood. These objects can emit 1000 times the energy of our entire Milky Way galaxy from a volume that it not much bigger than our Solar System, making them fearfully powerful.
