How Big Is Space – Interactive version
You've now reached the outer edges of our own solar system It would take you about 23 million years of continuous scrolling on this scale to get to the farthest regions of the observable universe, another 435,000,000,000,000,000,000,000 kmor 46 billion light years away. We think we'll stop here. Live long and prosper

Docking gives Intelsat telecoms satellite new lease of life Image copyright Northrop Grumman Two American satellites have docked high over the Atlantic in a demonstration of what many commentators expect to be a burgeoning new industry. One of the platforms is an old telecoms spacecraft low on fuel; the other is an auxiliary unit that will now take over all the former's manoeuvring functions. This will allow Intelsat-901 to extend its 19-year mission of relaying TV and other services by another five years. The event has been described as a major accomplishment by the firms involved.

Stars align for epic space missions Image copyright ESA Two of the most exciting space missions of the 2030s are likely now to be launched within a year of each other. European Space Agency member states are poised to increase the organisation's science budget on Thursday by 10%. This would make it possible to align projects to build a big X-ray telescope and a trio of satellites to sense the collision of gargantuan black holes. It's important they fly together because the insights they'll bring are highly complementary.

ISS crew blast off after long quarantine Image copyright Getty Images Three new crew members have arrived at the International Space Station (ISS) after a launch carried out under tight restrictions due to the coronavirus. The Russian Soyuz rocket carrying cosmonauts Anatoly Ivanishin and Ivan Vagner and Nasa astronaut Chris Cassidy took off from Kazakhstan on Thursday. Pre-launch protocols were changed to prevent the virus being taken to the ISS. Only essential personnel were allowed at the launch site for the blast-off. Support workers wore masks and kept their distance as the crew walked to the bus to take them to the spacecraft.

'Whodunnit' awareness test: How many changes can you spot? The clip initially appears to be a scene from a cliched murder mystery, with a trench coat–wearing detective interviewing the maid, butler and lady of the house over the death of Lord Smithe, who lies sprawled on the drawing room floor. But the sketch is merely the premise for a test designed to show just how bad we are at noticing things that we're not looking for – including on the roads. After the detective names the killer the scene is replayed, this time filmed from a camera that captures all the film crew's out-of-shot manoeuvrings. This angle reveals that the 50 second scene contained 21 glaring continuity errors; paintings, props and rugs were all switched half way through the shoot, and even the actor playing Lord Smithie's corpse was replaced. The advert ends with the message: "It's easy to miss something you are not looking for. On a busy road this could be fatal.

Dancing gargantuan black holes perform on cue Media playback is unsupported on your device Astronomers have been able to test key consequences of Einstein's theories by studying the way a couple of black holes move around each other. One of these objects is a true colossus - a hole weighing 18 billion times the mass of our Sun; the other not quite so big at "only" 150 million Sun masses. Scientists managed to predict their interactions very precisely.

Pentagon releases UFO videos for the record Media playback is unsupported on your device The US Department of Defense has released three declassified videos of "unexplained aerial phenomena". The Pentagon said it wanted to "clear up any misconceptions by the public on whether or not the footage that has been circulating was real". The videos had already been leaked in 2007 and 2017.

James Webb Space Telescope comes together Image copyright NASA/Chris Gunn The successor to the Hubble observatory has reached a key milestone in its construction. All the elements that make up the James Webb Space Telescope (JWST) have been brought together for the first time. It sets the stage for some critical tests that will hopefully lead to a launch to orbit sometime in 2021. JWST will use a colossal mirror and state-of-the-art instruments to try to see the glow from the very first stars to shine in the Universe.

Milky Way galaxy is warped and twisted, not flat Image copyright OGLE/Warsaw UNiversity Our galaxy, the Milky Way, is "warped and twisted" and not flat as previously thought, new research shows. Analysis of the brightest stars in the galaxy shows that they do not lie on a flat plane as shown in academic texts and popular science books. Astronomers from Warsaw University speculate that it might have been bent out of shape by past interactions with nearby galaxies. The new three dimensional map has been published in the journal Science. Moon landings: What was the 1969 Apollo 11 mission? Image copyright Reuters It's nearly 50 years since the US became the first country to land men on the Moon. The Apollo 11 mission was a huge moment in US and world history, but what exactly happened and why does it matter? Why did the US want to go to the Moon? A space race developed between the US and the then Soviet Union, after the 1957 launch of the first Soviet Sputnik satellite.

The CubeSat revolution changing the way we see the world Image copyright Alamy There is a beloved story about the dimensions of the space shuttle. Apparently the booster rockets had to fit through railway tunnels designed to accommodate a horse and cart. In short, the space shuttle boosters were the width of two horses' backsides. Apollo 11: Four things you may not know about the first moon landing Image copyright NASA Fifty years on, the Apollo Moon programme is probably still humankind's single greatest technological achievement. On 16 July 1969, astronauts Neil Armstrong, Buzz Aldrin and Michael Collins were strapped into their Apollo spacecraft on top of the vast Saturn V rocket and were propelled into orbit in just over 11 minutes. Four days later, Armstrong and Aldrin became the first humans to set foot on the lunar surface. Here's a visual guide to four lesser-known facts about the history-making mission. 1.

Jeff Bezos unveils Moon lander concept Image copyright Reuters Amazon entrepreneur Jeff Bezos has unveiled a mock-up of a new lunar lander spacecraft that aims to take equipment and humans to the Moon by 2024. The unmanned, reusable Blue Moon vehicle will carry scientific instruments, satellites and rovers. It will feature a new rocket engine called BE-7 that can blast 10,000 pounds (4,535 kg) of thrust. "It's time to go back to the Moon, this time to stay," said Mr Bezos.
