The talk schedule can be found at http://www.ast.cam.ac.uk/IOA/public/0607timetable.html. This week’s talk : Steve Wilkins will be telling us Why the future isn’t so bright – the history and future of star formation Next week’s talk : Derek Jones will be revealing A National Scandal: how we didn’t discover Neptune We have a selection of activities coming up for the Cambridge Science Festival: . Junior School Art Competition : Create a poster/picture that expresses Your View of the Universe. The prize is a half-day visit to your school by the Stardome Planetarium; but hurry! – the entry deadline is this coming Friday, 9th March. Do you know anyone who might enjoy an afternoon of activities about Astronomy for the Visually Impaired ? Sunday 18th March, 2-6pm, prior booking is essential. Open Afternoon : The IoA opens up its doors to everyone on Saturday 24th March, 4-8pm (followed by observing if the weather is clear). Full details of all these activities can be found at: http://www.ast.cam.ac.uk/public/csf/2007/ The Society for Popular Astronomy is holding their annual convention here at the IoA this coming Saturday, 10th March, 10am – 5.30pm. Admission to the event is free, and open to everyone. If you want more information, please look at http://www.popastro.com/convention07.htm. Astroblast is returning to the IoA! This year it is planned to be bigger and better; it will be held on Saturday 21st April. Further details can be found at http://www.astroblast.org.uk/ Astronomical object of the week : NGC 2362 is a beautiful open cluster of about 60 stars, all loosely bound to each other by gravity. These stars formed from the same gas cloud somewhere between 10 and 20 million years ago, the remnants of which are still present as faint wisps of nebulosity. The cluster is dominated by the very bright star, tau canis majoris, which is really a double system. The cluster appears as a faint haze around this star when seen through binoculars, and it requires a telescope to properly resolve individual stars. Iridium flares in the early evening are few and far between this coming week, Day start time altitude & direction 11 Mar 19:13:17 41° N 13 Mar 18:36:53 53° N However, to make up for it, both of these flares are expected to be particularly bright. For more details or the exact timing from somewhere other than Cambridge, look at www.heavens- above.com Tonight we intend to show you the following astronomical objects (weather permitting, of course): Saturn : and some of its brighter moons Beta Camelopardalis : a supergiant star that has a luminosity of over 3000 times that of our Sun Tau Canis Major : the brightest member of the bright open cluster of stars called NGC 2362. Algol :a star that periodically varies in brightness as it is eclipsed by a companion star Mizar : a star that has an easily-seen companion, Alcor NGC 1502 :an open cluster of stars, many of which are double stars M1 : the ‘crab nebula’ which is a remnant from a supernova explosion M42 : the ‘great’ nebula in Orion, a region of intense star formation M41 : an open cluster of stars The constellations of Camelopardalis, Canis Major and the Plough Chart of the night sky from Cambridge for 8pm on Wednesday 7th March (taken from www.heavens-above.com) You can see Venus to the West every evening after sunset until just after 8.30pm – it appears as a really bright ‘star’ above the horizon. Saturn is now easily visible in the night sky, bright and high in the constellation of Leo towards the south-east. If you are an early riser, you can catch Jupiter bright towards the south-east in the morning twilight. It rises at 2:14am. And finally, a site map to help you find your way back to the car in the dark if we are observing tonight.

  • NGC-2362 – (Caldwell 64) Open Cluster (Tau Canis Majoris Cluster) Introduction the Purpose of the Observer’S Challenge Is to Encourage the Pursuit of Visual Observing
    MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada March 2012 NGC-2362 – (Caldwell 64) Open Cluster (Tau Canis Majoris Cluster) Introduction The purpose of the observer’s challenge is to encourage the pursuit of visual observing. It is open to everyone that is interested, and if you are able to contribute notes, drawings, or photographs, we will be happy to include them in our monthly summary. Observing is not only a pleasure, but an art. With the main focus of amateur astronomy on astrophotography, many times people tend to forget how it was in the days before cameras, clock drives, and GOTO. Astronomy depended on what was seen through the eyepiece. Not only did it satisfy an innate curiosity, but it allowed the first astronomers to discover the beauty and the wonderment of the night sky. Before photography, all observations depended on what the astronomer saw in the eyepiece, and how they recorded their observations. This was done through notes and drawings and that is the tradition we are stressing in the observers challenge. By combining our visual observations with our drawings, and sometimes, astrophotography (from those with the equipment and talent to do so), we get a unique understanding of what it is like to look through an eyepiece, and to see what is really there. The hope is that you will read through these notes and become inspired to take more time at the eyepiece studying each object, and looking for those subtle details that you might never have noticed before.

(To see how big the universe is, check Maps on Page 7). There are probably at least 100 billion galaxies known to man in the universe, and about 300 sextillion stars. The diameter of the known universe is at least 93 billion light years (1 light year = 9.46×1012 kilometers or 9.46×1015 meters) or 8.80×1026 meters. According to General Theory of Relativity, space expands faster than the speed of light. Due to this rapid expansion, it is not brief whether the size of the universe is finite or infinite. The expansion of the Universe is due to presence of dark energy, which is found to be 73% and dark matter (23%). There is only 4% matter found. However, even though the universe is huge and massive, it has a very small density of 9.9 ×10-30 gm per cubic centimeters (excluding stars, planets and any other celestial body).

  • Central Coast Astronomy Virtual Star Party February 13Th 7Pm Pacific
    Central Coast Astronomy Virtual Star Party February 13th 7pm Pacific Welcome to our Virtual Star Gazing session! We’ll be focusing on objects you can see with binoculars or a small telescope, so after our session, you can simply walk outside, look up, and understand what you’re looking at. CCAS President Aurora Lipper and astronomer Kent Wallace will bring you a virtual “tour of the night sky” where you can discover, learn, and ask questions as we go along! All you need is an internet connection. You can use an iPad, laptop, computer or cell phone. When 7pm on Saturday night rolls around, click the link on our website to join our class. CentralCoastAstronomy.org/stargaze Before our session starts: Step 1: Download your free map of the night sky: SkyMaps.com They have it available for Northern and Southern hemispheres. Step 2: Print out this document and use it to take notes during our time on Saturday. This document highlights the objects we will focus on in our session together. Celestial Objects: Moon: The moon is 2 days past new, which is really good for star gazing. Be sure to look at the moon tonight with your naked eyes and/or binoculars! Mercury is rising right before the sun and may be a good target near the end of the month. Mars is up high but is shrinking in size as the weeks progress. *Image credit: all astrophotography images are courtesy of NASA unless otherwise noted.
