In September 2016, China unveiled the world’s largest telescope – an instrument engineered so finely it is 3 times more sensitive than Arecibo and may help in the international search for understanding more on the origin of the universe and the Big Bang. Sadly, since filming this video, FAST’s chief engineer and scientist, Professor Nan Rendong lost his fight with cancer. Not only was Professor Nan a talented and well-respected scientist who dedicated over 20 years to the FAST project, but we found him to be a kind, intelligent and dedicated man who took the time to explain his work and the importance of it to us. The Five-Hundred-Metre Aperture Spherical Telescope, known as FAST had been constructed over five years in a remote area of Guizhou province, south central China. It was built in a 45 million year old crater, unlikely to be affected by flooding and far from human interference. The 500m dish surpasses Arecibo radio telescope, built in Puerto Rico in 1963, as the world’s largest and is three times more sensitive in detecting radio waves thousands of light years away. FAST consists of 4450 individual panels and Chinese project engineers had to design a cable net of ten thousand cables to manipulate it to detect signals. FAST’s focus cabin is also unique thanks to a directional tracking system. A key mission for the telescope will be detecting pulsars, the matter that remains when a star eight times the size of the sun explodes. These pulsars rotate thousands of times per second and are the universe’s most accurate clock. Experience the construction and meet the creators of FAST: The World’s Largest Telescope.

Nearly five years after its celebrated arrival at Mars, the Curiosity rover continues to reveal Mars as a once-habitable planet. Early in the planet’s history, generations of streams and lakes created the landforms that Curiosity explores today. The rover currently is climbing through the foothills of Mount Sharp, a 3-mile-high mountain formed from sediment brought in by water and wind. This talk will cover the latest findings from the mission, the challenges of exploration with an aging robot, and what lies ahead.

he Alpha Centauri star system is ideal to search for habitable planets by various observing techniques due to its proximity and wide range of stellar masses. Following the recent discovery of an Earth-size planet candidate located inside the Proxima Centauri habitable zone, Dr. Marois will discuss this remarkable discovery and the planet’s potential to find life. He will also present our current instrument project for the Gemini South observatory, TIKI, to discover similar planets around the two Sun-like pair located 15,000 AU from Proxima Centauri. The Alpha Centauri system is the prime target of the Breakthrough Starshot program, a project to send small quarter-size probes to take resolve images of these new worlds, and to prepare for Humanity’s first step into a new star system.
Dr Marois completed his Ph.D. at the Université de Montréal in 2004. The main topic of his thesis work was to understand the limits in exoplanet imaging and to design innovating observing strategies. After his thesis, he did postdoctoral researches at the Lawrence Livermore National Laboratory, Univ. of California Berkeley and NRC. In 2008, while at NRC, he led the team that took the first image of another planetary system (HR 8799) using the Keck and Gemini telescopes. He is currently pursuing his research at the NRC Herzberg where he is part of the Gemini Planet Imager campaign, and leading the development of instruments for imaging Earth-like planets at Gemini South and at the TMT.

Aboard the International Space Station, Expedition 47 Commander Tim Kopra of NASA and Flight Engineers Jeff Williams of NASA and Tim Peake of ESA (European Space Agency) discussed life and research on the orbital outpost during a pair of in-flight interviews March 22 with online technology media outlets Gizmodo and The Verge. Williams arrived on the station on March 19 for a six-month mission, his record-breaking third long duration flight on the complex. Kopra and Peake are more than halfway through their six-month stay on the station.
After launching earlier in their Soyuz TMA-20M spacecraft from the Baikonur Cosmodrome in Kazakhstan, Expedition 47-48 Soyuz Commander Alexey Ovchinin and Flight Engineers Oleg Skripochka of Roscosmos and Jeff Williams of NASA arrived at the International Space Station on Mar. 19. The new crewmembers will join station Commander Tim Kopra of NASA and Flight Engineers Yuri Malenchenko of Roscosmos and Tim Peake of the European Space Agency, already onboard the station.

What is Dark Matter? – Space Documentary
By fitting a theoretical model of the composition of the Universe to the combined set of cosmological observations, scientists have come up with the composition that we described above, ~68% dark energy, ~27% dark matter, ~5% normal matter. What is dark matter?
We are much more certain what dark matter is not than we are what it is. First, it is dark, meaning that it is not in the form of stars and planets that we see. Observations show that there is far too little visible matter in the Universe to make up the 27% required by the observations. Second, it is not in the form of dark clouds of normal matter, matter made up of particles called baryons. We know this because we would be able to detect baryonic clouds by their absorption of radiation passing through them. Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter. Finally, we can rule out large galaxy-sized black holes on the basis of how many gravitational lenses we see. High concentrations of matter bend light passing near them from objects further away, but we do not see enough lensing events to suggest that such objects to make up the required 25% dark matter contribution.
What is space? What is Space Made of ? If you ignore the galaxies, stars & atoms, then the rest of empty space is mysterious. It is really not nothing. See this documentary to know more.
Most scientists believe the Moon’s formation resulted from a giant impact between the Earth and a mysterious object called Theia.

Quasars: the Brightest Black Holes – Lecture by Professor Carolin Crawford
Quasars are among the most dramatic objects anywhere in the cosmos. They emit prodigious amounts of energy, all due to a supermassive black hole at the heart of a galaxy. Visible far across the Universe, quasars can be used to trace both the early life of galaxies, and the properties of the intervening space.

When and how did the universe begin? A global group of astronomers wants to answer that question by peering as far back in time as a large new telescope will let us see. Wendy Freedman headed the creation of the Giant Magellan Telescope, under construction in South America; at TEDGlobal in Rio, she shares a bold vision of the discoveries about our universe that the GMT could make possible.
After three action-packed years on Mars, the Curiosity rover is ready to take on higher slopes of Mount Sharp.
Saturn’s ring system is an astrophysical disk that is neither light-years away nor billions of years in the past. We can visit this disk at close range and observe a number of phenomena that also operate in disks of other kinds. As a result, we see small-scale processes that shape ring texture, connect those processes to the bodies and structures that cause them, and watch closely as the disk changes with time.
We will discuss recent Cassini observations that elucidate disk processes including 1) “self-gravity wakes” and “spiral density waves,” both of which were originally proposed for galaxies but are observed with exquisite precision in Saturn’s rings, 2) “propeller” features caused by 100-meter to km-sized moonlets embedded in the disk; these are the first objects ever to have their orbits tracked while embedded in a disk, rather than orbiting in free space, and hold the potential of deepening our understanding of planetary migration, and 3) irregular edge shapes in the gaps opened up by larger moons (10 km and more), which may hold clues to angular momentum transport.
NASA astronaut Reid Wiseman or otherwise known as @Astro_Reid recounts his launch into space on a Soyuz rocket and his stay on board the International Space Station as a member of Expedition 40/41 from the Moving Beyond Earth Gallery at the Smithsonian’s Air and Space Museum.
