2nd August - Mercury at Greatest Western Elongation
Because Mercury orbits closer to the Sun than Earth, it always appears quite close to the Sun in the sky, being lost in its glare most of the time. However, Mercury will be at its furthest separation from the Sun as seen from Earth on 2 August when it reaches greatest western elongation, making it a great time to try and spot the Sun’s closest planet. Look to the east just before sunrise – it will look like a star-like point visible to the naked eye but will be incredibly close to the horizon, so you’ll need a good clear view without tall buildings and trees. Find out more about greatest elongations in our Astronomical phenomena blog written by David Southworth in our Education team.
3rd - 4th August (and 31st August) - Moon and Saturn Close in the Sky
9th August - Moon and Mars Close in the Sky
11th August - Moon, Mercury and Jupiter Close in the Sky
12th August - Partial Solar Eclipse (19:11)
During the evening of 12 August, we’ll be treated to a partial solar eclipse – the best one visible from the UK for the next several decades! As it will occur around sunset, the spectacle will be visible quite low on the horizon, so be sure to find clear views without tall buildings and trees that may block your view. Ensure you view the event safely by using solar eclipse glasses, pin hole projections, or telescopes with solar filters that have been setup correctly – do not look directly at the Sun. Look to the west / north-west, where first contact will occur at 18:15 (from Leicester). This is when you’ll begin to see the dark disk of the Moon creeping onto the right edge of our star. At 19:11, it will reach its maximum coverage where the Moon will be blocking about 90% of the Sun’s surface – leaving just a small crescent of sunlight from the top right limb of our star. The event will end shortly after 20:00 where the last contact of the Moon will be on the left edge of the Sun. Find out more in our blog: ‘The Great British Partial Solar Eclipse 2026’ written by Emma Mosley in our Public Programmes team. We’ll also be holding special Space Lates - Partial Solar Eclipse viewing event in the car park of the National Space Centre (weather permitting) so come and join us!
12th August - New Moon (18:36)
12th - 13th August - Peak of the Perseid Meteor Shower
16th August - Moon and Venus Close in the Sky
24th August - Launch of Chang'e 7
28th August - Partial Lunar Eclipse (05:12)
28th August - Full Moon (05:18)
30th August - Launch of Roman Space Telescope
The Nancy Grace Roman Space Telescope is NASA's newest flagship infrared observatory and is scheduled to launch at 12:26 on 30 August from Kennedy Space Centre, Florida, on a SpaceX Falcon Heavy rocket. It will head to L2 – a point in space 1.5 million km from Earth (where the JWST telescope is also positioned). It has a 2.4m primary mirror (the same diameter as that of the Hubble Space Telescope) but has been designed with a field of view 100 times larger than its predecessor thanks to one of its two main instruments – the wide field Instrument. This will allow the Roman Space Telescope to capture more of the sky with less observing time. It will measure light from a billion galaxies over the course of the mission lifetime to investigate some major cosmic mysteries like dark energy, dark matter, and take a census of distant exoplanets. It will also perform a microlensing survey (measuring the bending of light from a distant background star by a foreground object) to find roughly 2,600 exoplanets and will use its second main instrument - the coronagraph instrument to perform high-contrast imaging and spectroscopy of individual nearby exoplanets to learn more about these alien worlds.
