“Of all the sciences cultivated by mankind, Astronomy is acknowledged to be, and undoubtedly is, the most sublime, the most interesting, and the most useful. For, by knowledge derived from this science, not only the bulk of the Earth is discovered …; but our very faculties are enlarged with the grandeur of the ideas it conveys, our minds exalted above [their] low contracted prejudices.” –James Ferguson, “Astronomy Explained Upon Sir Isaac Newtons Principles, And Made Easy To Those Who Have Not Studied Mathematics” (1757) — Subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com — The Cosmic Perspective Long before anyone knew that the universe had a beginning, before we knew that the nearest large galaxy lies two and a half million light-years from Earth, before we knew how stars work or whether atoms exist, James Ferguson’s enthusiastic introduction to his favorite science rang true. Yet his words, apart from their eighteenth-century flourish, could have been written yesterday. But who gets to think that way? Who gets to celebrate this cosmic view of life? Not the migrant farmworker. Not the sweatshop worker. Certainly not the homeless person rummaging through the trash for food. You need the luxury of time not spent on mere survival. You need to live in a nation whose government values the search to understand humanity’s place in the universe. You need a society in which intellectual pursuit can take you to the frontiers of discovery …

Hubblecast 01: ‘Comet Galaxy’ Being Ripped Apart By Galaxy Cluster. The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster’s gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com • www.YouTube.com — Credit: • ESA/Hubble (M.

Hubblecast 31: Sky merger yields sparkling dividends. A recent NASA/ESA Hubble Space Telescope image captures what appears to be one very bright and bizarre galaxy, but is actually the result of a pair of spiral galaxies, like our own Milky Way smashing together at breakneck speeds. The product of this dramatic collision, called NGC 2623, or Arp 243, is about 250 million light-years away in the constellation of Cancer (the Crab). This object was a target of Hubble’s and a handful of its “sibling” spacecraft as part of a massive comprehensive sky survey called GOALS. — • www.youtube.com • www.youtube.com — Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. The object in the image, NGC 2623, is in the late stages of the merging process with the centres of the original galaxy pair now merged into one nucleus. However, stretching out from the centre are two tidal tails of young stars showing that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. The prominent lower tail is richly populated with bright star clusters — 100 of them have been found in these observations. The large star clusters that the team have observed in the merged galaxy are brighter …

Hubblecast 25: What’s Next? Amazing Telescopes Of The Future. The telescope has been mankind’s window on the Universe for four hundred years. It has provided scientists with unprecedented views of planets, stars and galaxies from our cosmic doorstep to the very depths of space and time. But despite their incredible performance, even the newest and most powerful telescopes leave room for improvement. Astronomers always want to venture beyond their current horizons. In this final chapter we take a look at things to come – the revolutionary ground-based telescopes and space observatories of the future. One thing is certain: there is much left to discover. — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com • www.YouTube.com — Welcome to the Hubblecast!

Science@ESA (Episode 4): Following The Redshift (Part 1) – The Earliest Stars and Galaxies In The Universe. From HST (Hubble Space Telescope) to JWST (James Webb Space Telescope). In this fourth episode of the Science@ESA vodcast series Rebecca Barnes will identify some of the key discoveries achieved with the famous Hubble Space Telescope, look at the concept of redshift, and meet a new telescope that will be used to uncover the early Universe. — • www.youtube.com • www.youtube.com — ‘Redshift’ is a key concept for astronomers. The term can be understood literally – the wavelength of the light is stretched, so the light is seen as ‘shifted’ towards the red part of the spectrum. Something similar happens to sound waves when a source of sound moves relative to an observer. This effect is called the ‘Doppler effect’ after Christian Andreas Doppler, an Austrian mathematician who discovered that the frequency of sound waves changes if the source of sound and the observer are moving relative to each other. If the two are approaching, then the frequency heard by the observer is higher; if they move away from each other, the frequency heard is lower. There are many everyday examples of the Doppler effect – the changing pitch of police and ambulance sirens, or train whistles and racing car engines as they pass by. In every case, there is an audible change in pitch as the source approaches and then passes an observer. Everyone has heard the increased pitch of an approaching …

Hubblecast 24: Beyond Earth – Telescopes In Space. There’s no better place for a telescope than space itself. Above the Earth’s atmosphere observations are no longer hampered by air turbulence, so telescopic images of distant stars and galaxies are razor-sharp. Unlike a ground-based telescope, an instrument in Earth orbit can operate twenty-four hours a day and reach every part of the sky. Observing from space also makes it possible to study types of radiation that are otherwise absorbed by the atmosphere. Little wonder that the Hubble Space Telescope has made so many contributions to astronomy. And Hubble is not alone – more than 100 space observatories have been launched since the 1960s.

Hail Science!! Celebrating 400 years since Galileo first peered into the milky dark with the 2009 International Year of Astronomy. With images from the Hubble and Spitzer Space Telescopes. Find free space images at nasaimages.org The Chromatics’ “Shoulders of Giants” free download and lyrics available at: www.astrocappella.com Music and Lyrics by Padi Boyd © 2008, The Johannes Kepler Project It was a calm and cloudless night but it was all still a blur A shaking of our Universe was just about to occur It was Summertime… 1609 when Galileo used his telescope for the very first time and he saw mountains and craters on the moon and a Milky Way with thousands of stars and he saw Jupiter, with four tiny moons he was the only man on Earth that night who knew That Copernicus was right come outside with me tonight and I can show you wonders of the world to surprise and delight I’ve got my telescope with me just wait until you see that on the Shoulders of Giants…. … we’ll see beyond! The world turns round and round now around 400 years have flown since Galileo’s telescope first focused the unknown Now we use bigger glass to peer into the past And we’re discovering the Universe’s secrets at last And there are geysers on Saturn’s icy moon and planets circling hundreds of stars while all the Universe expands like a balloon from Galileo’s tiny scope we’ve come so far Galileo was right when he looked out in the night and he discovered wonders of the world to surprise and delight I …
