View the International Space Station at its best from the UK

28 September 2019 Ade Ashford

If you have never seen the International Space Station (ISS), make the most of clear skies over the next few nights. It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 420-tonne, 109-metre-wide spacecraft over the British Isles and Western Europe.

The serene beauty of the International Space Station gliding silently across the sky needs nothing more than the naked eye to appreciate. But when the dazzling ISS is also in conjunction with a partially eclipsed Moon, Saturn and Jupiter on the 50th anniversary of Apollo 11’s launch, be sure to look low in the southeast through south around 10:06pm BST on 16 July 2019!

Have you ever seen the International Space Station (ISS)? It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 450-tonne, 109-metre-long spacecraft over the British Isles and Western Europe this week.

Urban dwellers may resign themselves to spotting the Moon, planets and the brightest stars with the unaided eye on a clear night, but every so often a bright satellite will catch your attention as it glides silently across the sky. The brightest is the 400-tonne International Space Station (ISS) whose orbit carries it directly overhead as seen from the British Isles and parts of Western Europe tonight.

The serene beauty of the International Space Station sailing silently overhead needs nothing more than the naked eye to appreciate. But when the dazzling ISS is also in conjunction with a pair of prominent Solar System bodies — such at the Moon and Saturn on the night of 2 August 2017 in the UK — you may wish to grab your binoculars and look low in the south-southwest just before 11:20pm BST.

Fermi space telescope expands its search for dark matter

14 August 2016 Astronomy Now

Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, six or more years of data from NASA’s Fermi Gamma-ray Space Telescope has broadened the mission’s dark matter hunt using some novel approaches.

If you chance upon a bright ‘star’ crawling across the sky in an arc from west to east, an object that doesn’t flash or possess red and green running lights (which is an aircraft), then you can be fairly certain that you’re looking at the International Space Station (ISS). Find out when and where to see it from the British Isles and Western Europe this week.

In recent nights, observers in the UK and Western Europe have seen the International Space Station (ISS) as a bright naked-eye ‘star’ moving slowly across the sky from west to east. On Thursday, 9 June, London is favoured for some close approaches of the ISS to the Moon, Jupiter and Saturn. If you see the Station, spare a thought for Tim Peake and the Expedition 47 crew on board!

Mercury and International Space Station transit the Sun

1 June 2016 Astronomy Now

French astrophotographer Thierry Legault travelled to the suburbs of Philadelphia, USA to capture both the International Space Station and planet Mercury transiting the Sun on 9 May. This image includes multiple stacked frames to show the Station’s path in the fraction of a second it took to cross the Sun, while Mercury appears as a black dot at bottom-centre.

Tim Peake’s ISS view of the waxing Moon

12 February 2016 Astronomy Now

In this image we see the young lunar crescent as seen from the International Space Station by ESA astronaut Tim Peake on 9 February 2016. At the time of the photograph the Moon was just 1.2 days old. Features on the Earth-facing side of the Moon not directly illuminated by the Sun are glowing softly due to earthshine, light reflected onto the Moon from our planet.
