SUMMARY:Jupiter The Giant Planet
DESCRIPTION:On these dark starry nights\, we are treated to a planetary delight as this celestial heavyweight lines up for our telescopes.\nJupiter is the largest planet in our solar system and could swallow ~1300 earths\, this gas giant planet is a turbulent environment as it spins on its axis once every 9.5 hours – this makes it the fastest rotating object in our solar system. Due to this exceptional rotational period\, Jupiter has a very turbulent surface with high-speed winds whipping its surface up into a visual drama on a cosmic scale. With bands and belts transition regions and big red spots\, Jupiter has it all\, and we have the kit to bring it alive for you all – see this amazing planet for yourself!\nTerms and conditions of booking\nSafety is our first priority – you must adhere to all instructions of the team leading the astronomy session and You must not do anything to compromise the health and safety of yourself or others and must report any concerns or risks to the onsite team immediately. Should you put yourself or others at risk this may mean that you are politely asked to leave the site.\nYour booking is non-refundable. Should we cancel the event for any reason we will however make a full refund or give the option of a transfer to another date. If you are unable to undertake dark sky observing because of cloud cover then we will offer you a 20% discount on a future booking made and taken within 8 weeks of the event.\nYou should bring appropriate clothing to keep you warm.\nYou should arrive at Grassholme no later than 15 minutes before the start of your session.\nGrassholme is set within the quiet upper Tees Valley and we ask that you drive safely and do not disturb residents with loud music\, or other disturbance late at night.\nYou should not do anything to disturb or destroy the visitor experience for other attendees and failure to do so may mean that you are politely asked to leave the site.\n.\nBy booking this event you are signing up to these terms and conditions.  \nhttps://bookwhen.com/grassholmeobservatory/e/ev-sw8u-20260201200000

SUMMARY:Aurora Night
DESCRIPTION:The event will begin with a personal welcome from our astronomer\, Gary Fildes.  Gary is a very experienced science communicator and astronomer\, and founder of the Kielder Observatory\, where he was Director and CEO for over 11 years.\nAfter the welcome\, Gary and the team will escort you into our new state-of-the-art classroom\, which has a cosy feel\, and a high definition (HD) projection system.  Gary will take you on a whistle-stop tour of the Universe.  Following this\, we will split into groups and\, weather depending\, start observing the sky\, with our array of telescopes and cameras.\nA fun-filled night\, with stunning graphics handouts\, experiments\, and stargazing\, with our advanced array of instruments.  Expert tuition from Gary and his team of astronomers\, as we take you on a journey of the heart and soul.\nOn certain nights throughout the year\, we may even see the Aurora Borealis from Grassholme.  It’s visible in these skies\, but the conditions have to be right to see them and those conditions can be very rare indeed.  Whilst we cannot guarantee you will see them\, and to be honest\, you probably won’t\, we can guarantee that you will leave well equipped on how you can spot them in future\, and what exactly they are.\nOn summer evening\, from June to early August onwards\, we may even glimpse other atmospheric phenomena\, such as noctilucent or night shining clouds.  During this time of year\, our northerly latitude prohibits the true dark skies\, as a twilight gives the sky a beautiful hue.\nTerms and conditions of booking\nSafety is our first priority – you must adhere to all instructions of the team leading the astronomy session and You must not do anything to compromise the health and safety of yourself or others and must report any concerns or risks to the onsite team immediately. Should you put yourself or others at risk this may mean that you are politely asked to leave the site.\nYour booking is non-refundable.

SUMMARY:Dark Sky Astronomy and Stargazing
DESCRIPTION:Tonight’s event promises to be a spectacular evening of astronomy.\nThe event will begin with a personal welcome from our astronomer\, Gary Fildes.  Gary is a very experienced science communicator and astronomer\, and founder of the Kielder Observatory\, where he was Director and CEO for over 11 years.\nAfter the welcome\, Gary and the team will escort you into our new state-of-the-art classroom\, which has a cosy feel\, and high definition (HD) projection system.  Gary will take you on a whistle-stop tour of the Universe.  Following this\, we will split into groups and\, weather depending\, start observing the sky\, with our array of telescopes and cameras.\nWith no Moon in the sky\, we will look out for the Milky Way\, and many deep sky objects like Galaxies nebulae\, and star clusters\, then use our robotic telescope to scour the skies for other jewels of the cosmos\, for us to ponder.\nThen it’s back into the classroom for a hot drink\, more astronomy photography questions\, and boundless knowledge and inspiration.\nWe’ve planned quite a night!\nTerms and conditions of booking\nSafety is our first priority – you must adhere to all instructions of the team leading the astronomy session and You must not do anything to compromise the health and safety of yourself or others and must report any concerns or risks to the onsite team immediately.

Expert tuition from Gary and his team of astronomers\, as we take you on a journey of the heart and soul.\nOn certain nights throughout the year\, we may even see the Aurora Borealis from Grassholme.  It’s visible in these skies\, but the conditions have to be right to see them and those conditions can be very rare indeed.
