    Dawodang telescope, China
    The Five hundred meter Aperture Spherical Telescope (FAST; Chinese: 五百米口径球面射电望远镜

    FAST, in full Five-hundred-metre Aperture Spherical radio Telescope, astronomical observatory under construction in the Dawodang depression, Guizhou province, China, that when completed in September 2016 will be the largest single-dish radio telescope in the world. FAST’s collecting area will be more than 2.5 times that of the 305-metre (1,000-foot) dish at the Arecibo Observatory in Puerto Rico. FAST will be a spherical reflector 500 metres (1,600 feet) in diameter sitting in a natural depression
    It will have a cost of 700 million yuan (around 110 million US dollars at the time).
    The site's Karst depression is large enough to host the 500-meter telescope and deep enough to allow a zenith angle of 40°. The light-weight feed cabin —suspended 140 m above the reflector— will be driven by cables and servomechanisms in addition to a parallel robot as a secondary adjustable system to move with high precision

    No need to quote all the pics in a post! CM

    Unfortunately, all photos, barring one that astronaut Scott Kelly took last year, are all gray scale (black and white) and then manipulated to produce colors that they think we would see with our naked eyes, using RGB filters.
    Cassini included. But here's an article that explains the Saturn and Earth "color" shot from Cassini.
    http://www.dpreview.com/articles/800...ings-and-earth

    I just found the color photo the astronaut took. Seems he's taken more, according to this article. It was big news when he did the first one. There are now 29 color images from him on the bottom site link. I think, maybe, that another was taken years ago with 70mm film in a hopped up Hassleblad of Earth itself. Not sure on that one.

    The binary asteroid Didymos, has a main body “Didymaion”, about 800 meters in diameter, and a small moon orbiting around, “Didymoon2, of about 170 meters. Didymoon is perfect to test a spatial operation that could be of importance in the future for our planet: to deflect a solar system body on a collision course with Earth.
    Experts from the European Space Agency (ESA) have chosen this binary system as an objective of the AIM mission (Asteroid Impact Mission), which should start in October 2020 to Didymos in June 2022, when it will come to about 16 million of kilometers from Earth.
    The project is a collaboration with the Dart Mission (NASA) that will send the missile to change Didymoon orbit while the ESA mission will be to follow the impact and evaluate the changes in the orbit

    The European plan includes lowering a probe to the ground of the asteroid and drop a small satellite called CubeSat, which fulfill different scientific research purposes.

    To celbrate it's 26 year in Orbit the Hubble telescope took this photo the Bubble Nebula.

    NGC 7635 or Bubble Nebula is located in the constellation Cassiopeia about 8,000 light-years away.... the nebula itself is 10 light-years in diameter!

    NGC 7635 Is a giant gas bubble abd the star inside of it (SAO 20575) is between ten and twenty times the mass of our Sun.
    The gas sphere is still growing at more than 100 000 kilometres per hour.

    Winter i Charon

    Charon winter lasts about 100 (Earth) years, when it ends, the methane that accumulates in the north pole is transformed by the sun in red chemicals

    Rosetta Mission

    .

    Rosetta ended the mission today and landed in "her" comet.
    Rosetta was a space probe built by the European Space Agency launched on 2 March 2004. Along with Philae, its lander module, Rosetta performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P).
    During its journey to the comet, the spacecraft flew by Mars and the asteroids 21 Lutetia and 2867 Šteins.
    On 6 August 2014, the spacecraft reached the comet and performed a series of manoeuvres to be captured in its orbit. On 12 November, the lander module performed the first successful landing on a comet,though its battery power ran out two days later. Communications with Philae were briefly restored in June and July 2015, but due to diminishing solar power, Rosetta's communications module with the lander was turned off on 27 July 2016.
    On 30 September 2016, the Rosetta spacecraft ended its mission by landing on the comet near a pit called Deir el-Medina.

    On Monday China launched the Long March 2F rocket with the Shenzhou-11 spacecraft on board and two astronauts, Jing Haipeng and Chen Dong from the Jiuquan launch center in the Gobi Desert. After 13 minutes the capsule entered orbit and in two days and will dock the space lab Tiangong 2, where the astronauts will spend 30 days before returning to Earth.
    The mission is key to the Chinese space program, which seeks to build and operate a station in 2022. China does not participate in the development of the International Space Station because the US Congress prohibited the NASA work with China on national security issues.
    The two astronauts, will be 33 days in orbit. Their aim is to check the proper functioning of the space laboratory that was launched a month ago. According to Chinese state media, they will also be carry out "experiments in the field of medicine and space technologies,"
    China plans new missions to the Moon and Mars. In 2018 is expected to launch a probe into the far side of the moon with the aim of bringing samples to be examined, while in mid-2020 is expected to launch another mission to Mars in order to study its atmosphere and surface. Around 2025, China hopes to send a manned mission to the moon.

    «Nature» published the results of a research by Emerson J. Speyerer, Reinhold Z. Povilaitis,
    Mark S. Robinson, Peter C. Thomas & Robert V. Wagner (Arizona State University) based in the high resolution lunar images obtained by the Lunar Reconnaissance Orbiter probe for seven years.
    The observations identified 222 new impact craters on the Moon of more than 10 meters in diameter, exceeding by 33 percent the number predicted by estimates.
    In addition to these impacts, scientists observed a surprising number, of 47000, small changes in the surface caused by small impacts of materials released by the greatest impacts. The swipe of a meteorite throws various types of waste, some at a speed of 16 km per second. This material removes the top layer of lunar soil and changes its brightness. At this rate the materials of the uppermost surface of the moon are completely transformed every 80,000 years or so.

    Jupiter was at it's closer distance from Earth this April

    The first photo was taken from Atacama observatory in Chile in February, the second by Hubble telescope in April the 4th.



    A second Great Spot has been discovered on Jupiter by University of Leicester astronomers, rivaling the scale of the planet's famous Great Red Spot and created by the powerful energies exerted by the great planet's polar aurorae.

    J025 The Rock!

    .

    An asteroid, the size of the Gibraltar Rock, discovered nearly three years ago, approached the Earth last Wednesday, April 19, at 12.24 GMT.
    The asteroid crossed at about 1.8 million kilometers, which is 4.6 times the distance between our planet and the Moon. No known space rock of that size has ever come so close, (just don’t ask the dinosaurs!), but NASA says there was no chance it could have collided with us.

    The asteroid, known as the 2014 JO25, was discovered in May 2014 by astronomers from the Catalina Sky Survey near Tucson, Arizona.

    Given its incredible dimensions, it has been dubbed "The Rock", in honor of the sturdy American actor and professional wrestler Dwayne Johnson, who also has an imposing appearance.

    Tianzhou 天舟

    Yesterday 20th April China launched the Tianzhou:

    The Tianzhou in Chinese: 天舟, means "Heavenly Ship" and it's a Chinese automated cargo spacecraft developed from the Tiangong-1 to resupply it's future modular space station. It was first launched on the Long March 7 from Wenchang on April 20, 2017. It is scheduled to demonstrate autonomous propellant transfer.
    It weights 13.000 Kg and can take as much as 6.500 Kg. (including 2.000 Kg fuel)
    The ship is 3,35 meters in diameter and 9 meters long, and was carried buy a Long March 7-Y2,
    With this Chine is following USA, Russia and... Space X

    Re: Space

    Everybody that has been in Space is in this graphic:
    Of 593 astronauts; 326 are Americans and 119 Russians, follows China with 10 and Japan with 7.
    In average Chinese cosmonauts are the youngest, while Japan has the highest percentage of women. 75 Astronauts are from different countries and last but not least, 7 are "space tourists" and the SpaceShipOne 2 pilots.
    India is also trying to appear in the list and is the first Asiatic country in sending a probe to Mars.
