🌍Where in the World?
The Copernicus Sentinel-2 mission captures the colourful waters of two salty lakes in East Africa: Lake Natron in northern Tanzania and Lake Magadi in southern Kenya.

Lake Natron, the large lake at the bottom of the image, is 56 km long. It is rather shallow, only reaching a depth of 3 m, although its depth varies during the year. There can be as many as 2.5 million flamingos congregating on the lake, which also offers a habitat for thousands of other species of waterbird.

The smaller Lake Magadi, at the centre top, is located in a vast depression in an area of volcanic rock. No permanent river enters the lake, which is fed only by surface runoff when it rains.

This image was acquired on 12 February 2023 during the short dry season, immediately before the main rainy season that begins in March. Owing to algae that thrive on the salt, both lakes are naturally red or pink, especially during the dry season when water evaporates and the salts become more concentrated. Here, however, the colours are because the image processing included Sentinel-2’s near-infrared channel, which helps to reveal different information than what is yielded in a natural colour image.

While heavy shades of red highlight vegetated areas and dominate this false-colour image, the seasonal flowering of algae in the lakes appears green. The bright white and blue areas along the shores depict a mixture of sand, salt and mud flats. Salt crusts, resulting from evaporation caused by high temperatures, can be spotted as white dots speckling the waters.

⭐SUNDAY SPACE FACT ⭐

Neutron stars are the densest and tiniest stars in the universe, and even though they only have a radius of about 10 km, they have a mass of one or two Suns.

They are born from a core-collapse supernova explosion and have been known to spin as fast as 716 times per second because of conservation of angular momentum in the explosion!

UPDATE 🌡️

Last night was colder again with the Grass Minimum temperature reaching -9.6 °C!
This matches the second coldest Grass Min recorded for November in 2009, and is only beaten by 14th November 2019 when the Grass Min temperature reached -10.5 °C 🥶

Last night we recorded a Grass Minimum temperature of -8.8°C!
This is the 5th coldest November reading that we have on record for this parameter (since 2000)❄️🥶

You can bring your telescope along to the clinic and get expert advice on how best to see the night sky! 🌖

The clinic will run at 7pm, and then again at 8pm, so there will be plenty of opportunity to ask your questions.

Star Gazing evening is from 7pm-9pm. Buy your tickets here: https://armaghobservatoryplanetarium.ticketsolve.com/ticketbooth/shows/1173648714

🚀EIRSAT-1 Launch today!🛰

Did you know that Ireland's first satellite is being launched into space today? 'EIRSAT-1' stands for 'Educational Irish Research Satellite'. A team of students in University College Dublin, with support from academic and professional staff, has designed, built, tested, and will operate, Ireland's first satellite, a 2U CubeSat. EIRSAT-1 is carried out with the support of the Education Office of the European Space Agency, under the educational Fly your Satellite! Programme.

You can watch the live stream of the launch from 17:45 on ESA TV: https://www.esa.int/ESA_Multimedia/ESA_Web_TV

🗣This image shows an artist’s impression of what nightglow might look like to an astronaut in the polar winter regions of Mars at night. The green glow occurs when oxygen atoms high up in the atmosphere combine to form oxygen molecules.

This simulated view was created using a real but darkened image of the martian surface from the panoramic camera of NASA’s Opportunity rover, and a synthetic nightglow corresponding to the real colour of the oxygen emission.

A very Georgian Festival!

As the Georgian Festival comes to a close, we wanted to share an images of our own Gorgeous Georgians from our Very Georgian Collection Tour on Friday and Saturday.

We had so much fun showing off our King George III collection. It was the first time in many years that this collection has been seen in public!

We hope you've all had a wonderful Georgian Festival, and we can't wait for next year!

November’s full moon is also known as the ‘Beaver Moon’ 🦫

This nickname was given by early Native American tribes because this was the time of year to set the beaver traps before the swamps and rivers froze.

This month’s Full Moon will occur tomorrow, 27th November, and will reach peak illumination at around 9:16am.

It is our third and final day at the UK Space Conference, and to say we've had fun would be a serious understatement! 🤩

Today, Rok and Anna were on hand once again with our 'Pop Rocket' workshop, and helped launch some amazing rockets created by the school children. Let's just say, there are some very talented budding engineers out there!🚀

It has been a fantastic three days, and we really have had a blast. A huge thanks has to go to the UK Space Conference for having us. It has been an amazing experience seeing all of the cool industries, as well as meeting so many amazing astronauts and hearing about their experiences.🧑‍🚀

Same again next year? 🪐

Today, we were very lucky to be joined by none other than ESA Astronaut and British Paralympic Sprinter, John McFall! Rok and Kerem couldn't believe their luck!

John was nice enough to stop by and help out with our Pop Rocket workshop, and he was a huge hit with the kids. 🧑‍🚀
After all, who better to help blast off rockets than an actual astronaut?!🚀

Join us this Georgian Festival for a Very Georgian Collections Tour of the Armagh Observatory.

Since the 1840's we have preserved and held some of the instruments used by King George III including this Short Telescope from 1769. This telescope has not been on public display in decades due to the delicate construction. Find out the history of this telescope, and see how it was used this weekend!

Our last remaining tickets are for:

🌍Where in the World?
This rare, almost cloud-free view of the remote Elephant Island in Antarctica was captured in February 2023 by the Copernicus Sentinel-2 mission.

Lying in the Southern Ocean about 250 km northeast off the tip of the Antarctic Peninsula, Elephant Island is one of the outermost of the South Shetland Islands. It owes its name to both the sighting of elephant seals along its shores and its elephant-like shape, here the ‘trunk’ is partially covered by clouds.

This mountainous island is covered by ice. The highest peaks are Mount Pendragon, which reaches around 970 m, visible on the southern end, and, moving northeast, Mount Elder, which reaches around 945 m.

The variations in the colour of the waters surrounding the island are due to sediment eroded by the flow of ice and carried by meltwater into the ocean.

Dramatic changes in Antarctica’s ice have become synonymous with the climate crisis. The continued observations from satellites are key to surveying the remote polar regions. Satellites can monitor the melting ice sheets caused by rising temperatures and the subsequent rising of sea levels, as well as the impact on global ocean currents caused by the increased influx of freshwater into ocean. This is paramount to improving our understanding of the Earth system and to providing evidence on the impact of climate change.
