Hubblecast Episode 40: Wide Field Camera 3 (WFC3) – Hubble’s New Miracle Camera In early 2009, a team of astronauts visited Hubble to repair the wear and tear of twenty years of operating in a hostile environment – and to install two new instruments, the Cosmic Origins Spectrograph, and Wide Field Camera 3 – better known as WFC3. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — Wide Field Camera 3 (WFC3) is a combined ultraviolet, visible and infrared camera that dramatically extends Hubble’s ability to image astronomical objects. With these new capabilities, Hubble is still pushing the boundaries of science after two decades in orbit. In episode 30 of the Hubblecast, we saw some of the very first pictures to come back from Wide Field Camera 3, Hubble’s newest and most advanced instrument. Today we’re going to look at some of the science behind these pictures. We’ll find out how this remarkable new camera is helping Hubble to see the invisible, look far back in time and spot objects further away from us than ever before. WFC3 was installed on Hubble in place of WFPC2, the Wide Field and Planetary Camera 2, which for many years had been the main workhorse instrument on Hubble. Not only do the two instruments have very similar names, and look virtually identical, the capabilities of WFC3 are also in some respects just a tweaked version of those of its predecessor — although with sharper pictures and more …

One of the Universe’s open questions maybe a step closer to be answered thanks to over 30 atoms of antihydrogen that have been trapped and stored by scientists at the European Organization for Nuclear Research, Cern. According to a written statement, this opens the path to new ways of making detailed measurements of antihydrogen, which will allow scientists to compare matter and antimatter, the latter being what annihilates ordinary matter in a single explosive flash of energy.

Astronomers believe they’ve found the oldest thing they’ve ever seen in the universe: It’s a galaxy far, far away from a time long, long ago. Hidden in a Hubble Space Telescope photo released earlier this year is a small smudge of light that European astronomers now calculate is a galaxy from 13.1 billion years ago. That’s a time when the universe was very young, just shy of 600 million years old. That would make it the earliest and most distant galaxy seen so far. Source: AP/ESO

This montage was created to demonstrate that it is the scientific method alone that has elevated the standard of living of many populations to soaring heights and can do so for all the world’s people. Science is not an ideology, but a method. A method which can free us from the shackles of destructive, divisive, superstitious thinking and create a peaceful, sustainable world where the united human race harmonises with the laws of nature, rather than arrogantly ignores them. —————————— You as a human being have evolved to respond to the world around you on impulse. You will instinctively jump out of the way if, say, a bus comes careening towards you. You know it would have a fatal effect if you didn’t. Even if you had never seen such a thing happen to a person before, you can instinctively calculate the weight of the bus, its size, its speed, and you will know that your frail body does not stand a chance. You know this because your very perception is built to comprehend the world in which you live. Defy it, and you will perish. As soon as you realise that this is a certain fact of life, you can apply that mentality to everything that you do. As the old Stoic saying goes: ‘Virtue exists in a will which is in agreement with nature’. This means that if what you choose to do is done without resistance to what you cannot control, then you will not encounter suffering as much. It is a certainty that you cannot break the laws of nature. They are firmly stuck …
