A month in space: quantum teleportation, a shuttle's final flight and mysterious Martian spheres – in pictures

Our pick of the best space-related images from last month includes the first experimental steps towards a global quantum internet, space shuttle Endeavour's final journey, and the spherical objects on Mars that have left scientists scratching their heads
A month in space: A Chinese rocket takes off with the Vene
A Chinese rocket lifts off in the Gobi desert on 29 September carrying the Venezuelan Earth observation satellite Miranda. The $140m satellite is named after the Venezuelan independence hero Francisco de Miranda and will provide images for mapping agriculture, spotting illegal drug crops and monitoring floods Photograph: AFP/AFP/Getty Images
A month in Space: Space Shuttle Endeavour Ferried by Shuttle Carrier Aircraft
On 19 September, the space shuttle Endeavour flew over Houston, piggybacking on Nasa's Shuttle Carrier Aircraft. The shuttle was en route to Ellington Field near the Johnson Space Center, where it made a scheduled stopover. This was the first leg of Endeavour's journey, which concluded in a crawl through Los Angeles ending on Sunday 14 October at the California Science Centre

A month in Space: An enormous halo of hot gas (in blue) around the Milky Way galaxy
Astronomers used the Chandra X-Ray Observatory to find evidence that the Milky Way is embedded in an enormous blob of hot gas. This artist's illustration shows the halo around our galaxy and two small neighbouring galaxies. The halo's mass is estimated to be equivalent to the mass of all the stars in the Milky Way. If its size and mass are confirmed, the halo could be the solution to the 'missing-baryon' problem

A month in Space: Soyuz 30
On 7 September, Nasa astronaut Joe Acaba (left) and Russian cosmonauts Gennady Padalka and Sergei Revin (centre and right) conducted a 'suit leak check' in the Soyuz spacecraft in preparation for their return to Earth on 16 September Photograph: ISS/NASA
A month in Space:  Japan Aerospace Exploration Agency astronaut Aki Hoshide
Japanese astronaut Aki Hoshide takes a picture of himself during a spacewalk outside the International Space Station. Hoshide and Nasa astronaut Sunita Williams (visible in the reflections of Hoshide's visor, apparently) completed the installation of a Main Bus Switching Unit and installed a camera on the space station's robotic arm. On Monday 17 September, Williams became the second woman to take command of the orbiting outpost Photograph: ISS/NASA
A month in Space: Rover Takes Self Portrait
The Curiosity rover also took a picture of itself – using a camera on its arm – but left the dust cover on. The purpose of the picture was to check that the cover on the Mars Hand Lens Imager (MAHLI) was free of debris, but the picture also captures a cloudy image of the top of the Remote Sensing Mast, showing the Mastcam and Chemcam cameras Photograph: Malin Space Science Systems/JPL-Caltech/NASA
A month in Space: Curiosity on the Move
After a few short drives, Curiosity's progress can be seen from orbit on 2 September. Monitoring the tracks over time will provide clues about how the surface is changing as dust is deposited and eroded Photograph: University of Arizona/JPL/NASA
A month in Space: NASA's Curiosity rover found evidence for an ancient stream on Mars
The rover found evidence of an ancient, flowing stream on Mars, including the rock outcrop pictured here, which the science team named 'Hottah' after Hottah Lake in Canada's Northwest Territories

A month in Space: Little Martian Spheres That Don't Taste Like 'Blueberries'
Meanwhile Nasa's veteran rover Opportunity sent back a picture of mysterious spherical objects at an outcrop called Kirkwood in the Cape York segment of the western rim of Endeavour Crater. Each spherule is about 3 millimetres in diameter Photograph: Modesto Junior College/USGS/Cornell Univ./JPL-Caltech/NASA
A month in space: Stabilising laser
Physicists passed a milestone in the development of a 'quantum internet' by transmitting quantum states between telescopes on La Palma and Tenerife – a record distance of 143km. The visible laser beam was used to stabilise the telescopes sending and receiving the quantum signal. In theory, 'quantum teleportation' will enable the exchange of messages with greater security, and allow calculations to be performed much more efficiently than is currently possible Photograph: IQOQI Vienna/Austrian Academy of Sciences
A month in Space: a stellar nursery nicknamed the Seagull Nebula
The cloud of gas that forms the head of the Seagull Nebula. The cloud glows brightly due to radiation blasting from a very hot young star at its heart. The entire nebula, which resembles a seagull in flight, has a wingspan of over 100 light years. See the whole bird here Photograph: ESO
A month in Space: James Webb Space Telescope Mirrors 'Can
Mirror segments for the James Webb Space Telescope were packed up in special canisters for shipping to Nasa from Ball Aerospace & Technologies Corp of Boulder, Colorado, where they were made

A month in Space: Webb telescope's first two flight mirrors
Through the looking glass: Technicians check one of the mirrors in the clean room at Nasa's Goddard Space Flight Center in Greenbelt, Maryland. Each of the infrared telescope's 18 hexagonal primary mirrors – which will form a single mirror in space – measures more than 1.3 metres across and weighs approximately 40kg. The segments are made of beryllium coated with gold. The telescope will be capable of peering through clouds of dust to the first galaxies to form after the big bang, and is scheduled for launch in 2018 Photograph: Chris Gunn/NASA
A month in space: A-Glimmer-from-a-Dark-Cosmic-Era
Astronomers spotted what could be the most distant galaxy ever seen, looking further back in time than ever before into the 'cosmic dark ages' when the universe was just 3.6% of its current age. Light from the primordial galaxy took around 13.2bn years to reach Nasa's Spitzer and Hubble telescopes. To see the galaxy astronomers relied on 'gravitational lensing', a phenomenon predicted by Einstein whereby the gravity of objects in the foreground warps and magnifies light from more distant objects Photograph: Hubble Space Telescope /NASA/ESA
A month in Space: The Royal Observatory's 2012 Astronomy Photographer of the Year
The Whirlpool Galaxy. Faint trails of light show its small companion galaxy being gradually torn apart by the gravity of its giant neighbour.

A month in Space: The  oddly shaped Pencil Nebula (NGC 2736)
The Pencil Nebula, part of the remnants of a supernova explosion about 11,000 years ago. The image was captured by the MPG/ESO 2.2-metre telescope at the European Southern Observatory's La Silla Observatory in Chile Photograph: ESO
A month in Space: Hubble goes to the eXtreme,  the deepest ever view of the Universe
Astronomers combined 10 years of images from the Hubble Space Telescope to create the deepest ever view of the universe, the eXtreme Deep Field, which includes 5,500 galaxies. The image delves into a small patch of space in the constellation Fornax (The Furnace) Photograph: Hubble Space Telescope /NASA/ESA
A month in Space: Full Dark Energy Camera image of the Fornax cluster of galaxies
The Dark Energy Camera – the world's most powerful digital camera, based on a mountaintop in Chile – opened its eye for the first time on 12 September. This is a composite image of the Small Magellanic Cloud, a dwarf galaxy that is a satellite of our own Milky Way galaxy. The 57-megapixel camera is part of efforts to explain the 'dark energy' that is driving the accelerating expansion of the universe Photograph: Dark Energy Survey Collaboration/NOAO
A month in Space: Earth as 'Pale Blue Dot'
This image was taken by Voyager 1 on 14 February 1990 when the spacecraft was 6.4bn kilometres from Earth. At that distance our home planet has been reduced to a pale dot. On 5 September 2012, exactly 35 years after its launch, the craft is now 18.21bn kilometres from home Photograph: NASA
A month in space: The debris from a supernova observed in 1604.
In 1604, Johannes Kepler witnessed what appeared to be the birth of a new star that was much brighter than Jupiter but which then dimmed over several weeks. What Kepler was actually seeing was the thermonuclear explosion of a white dwarf star. The debris is still visible and is known as the Kepler supernova remnant. Observations by Nasa's Chandra X-ray Observatory now suggest the explosion was even more powerful and further away than astronomers thought Photograph: Chandra X-ray Observatory Center/NASA
