Earth's polar skies have exhibited eerie blue-white glowing clouds at  twilight every summer since the late 1800’s. These Noctilucent clouds form in upper layers of the Earth’s atmosphere and can be seen from high latitudes on Earth. To see them: The sky must be clear. The atmosphere, where they form, must be sunlit, so the sun must be less than 16 degrees below the horizon. The background sky must be dark enough for the clouds to stand out. Viewing location should be at a latitude north of 45 degrees, Eruptions from Krakatoa in 1883 drew attention to noctilucent clouds. Dust from the volcano spewed into the atmosphere causing spectacular colourful sunsets for several years. What causes them? Noctilucent clouds are at altitudes of around 50 miles and normally too faint to be seen, they are only visible when lit by sunlight from below the horizon, while lower layers of the atmosphere are in the Earth's shadow. Ice crystals in clouds grow on dust nuclii: Water gathers on dust forming droplets or ice crystals. This happens all the time in clouds, at altitudes up to about 9.5 miles. It is unlikely that wind-blown dust reaches 50 miles high. So scientists think that dust causing noctilucent clouds may originate from space? Each day, Earth encounters millions of meteoroids ramming into our atmosphere to produce ‘shooting stars’.Tiny particles remain suspended as they break up. Water vapour carried upwards from moist lower atmosphere toward the mesosphere produces clouds at a high altitude.

Before 1998 Jays never visited gardens. They began visiting possibly to search for food. Magpies once chased them, but nowadays, Magpies rarely bother Jays in the garden. Jays often visit in pairs, but if three or four birds appear, rivalry starts - one or more birds of an assumed pair chasing the others. The Jay is intelligent and can extract peanuts from peanut bags to be eaten immediately or carried off in their crop for later. This is one of a pair which have appeared regularly in our garden this month(April)-so Imanaged to grab a quick shot or two
Rock Samphire (Crithmum maritimum) belongs to the carrot family and is commonly found on coastal rocks.It is edible and aromatic  The plant has fleshy, bright-green leaflets and umbels of tiny, yellowish-green flowers between June and September. This is a treat for foragers and the young leaves sprinkled with salt (after removing stalks and flowers) boiled and covered with vinegar make a tasty pickle. Samphire has been used for thousands of years. It was cultivated and sold on London streets. The name 'samphire' comes from 'herbe de St Pierre' .
What is it? 36 Oxford Ragwort still grows in the old railway yard in Cookstown-it has persisted since the railway closed. Oxford Ragwort was spread by the transport system-mainly railways.
The plant began in UK began with a specimen from Mount Etna, replanted in Oxford University's gardens. Seeds reached Oxford Railway Station railway station and the plant spread from there. The slipstream caused by trains carried the fluffy seeds far and wide along. railway lines and beyond -Tthe railway carried the plant to Cookstown.
