Exploring The High Energy Universe

Science@ESA Vodcast (Episode 5, Part 1): The Untamed, Violent Universe - Exploring The High Energy Universe.



The Science@ESA vodcasts explore the extraordinary Universe in which we live as it is seen through the "eyes" of ESA's fleet of science spacecraft.

In this fifth episode of the Science@ESA vodcast series Rebecca Barnes will give us a glimpse of the hot, energetic and often violent

Universe revealed through X-ray and gamma-ray astronomy, look at ESA missions that detect this hidden light and find out how the science that these missions perform is meticulously planned.

What is a gamma-ray? And how does an X-ray in space work?

X-rays and gamma-rays are like the light we can see with our eyes and the radio waves we can detect with radio and TV sets. The only difference is how fast they vibrate.

Radio waves vibrate the most slowly, then microwaves and infra-red (heat) waves, then the colors red to violet, then ultra-violet radiation (which causes sun-burn among other things) then X-rays, and finally (vibrating the most quickly) gamma-rays.

ESA's INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) is detecting some of the most energetic radiation that comes from space. It is the most sensitive gamma-ray observatory ever launched. INTEGRAL is an ESA mission in cooperation with Russia and the United States.

Why do people laugh at creationists? part 1-10

Why do people laugh at creationists?

The only people so stupid as to not understand the answer are the creationists themselves.

Brought to you from Thunderf00t, this superb series explores the unproven beliefs that are treated as factual by many religions and the extremes to which some followers have taken them. Case studies in this series include various creationists like VenomFangX, Kent Hovind, Ken Ham and just the fundamentalist Christian population in general.

(part 1)







CORRECTION Stars in galaxy in half a trillion, not half a billion.


correction, the thickness of the Hovind ice sheet should actually be 400 km rather than 1000km. However this approximation does not change the core of the argument that no light can penetrate beyond at best the first one km, or the fact that it would cooked the Earth on falling down, and drowned in permanently.

VISTA - The World's Most Powerful Survey Telescope

ESOcast 12: VISTA - A Pioneering New Survey Telescope Starts Work.

VISTA (the Visible and Infrared Survey Telescope for Astronomy) is a new telescope that has just started work at ESOs Paranal Observatory in Chile and has made its first release of pictures.

VISTA is a survey telescope working at infrared wavelengths and is the worlds largest survey telescope. Its large mirror, wide field of view and very sensitive detectors will reveal a completely new view of the southern sky.

Spectacular pictures of the Flame Nebula, the Centre of the Milky Way and the Fornax Galaxy Cluster show that it is working very well.



VISTA is the latest telescope to be added to ESOs Paranal Observatory in the Atacama Desert of northern Chile. It is housed on the peak adjacent to the one hosting the ESO Very Large Telescope (VLT) and shares the same exceptional observing conditions.

VISTA's main mirror is 4.1 metres across and is the most highly curved mirror of this size and quality ever made — its deviations from a perfect surface are less than a few thousandths of the thickness of a human hair — and its construction and polishing presented formidable challenges.

VISTA was conceived and developed by a consortium of 18 universities in the United Kingdom led by Queen Mary, University of London and became an in-kind contribution to ESO as part of the UK's accession agreement. The telescope design and construction were project-managed by the Science and Technology Facilities Council's UK Astronomy Technology Centre (STFC, UK ATC).

Provisional acceptance of VISTA was formally granted by ESO at a ceremony at ESO's Headquarters in Garching, Germany, attended by representatives of Queen Mary, University of London and STFC, on 10 December 2009 and the telescope will now be operated by ESO.

Born In Beauty: New Planetary Systems In The Orion Nebula

Hubblecast 32: Born in Beauty - Proplyds in the Orion Nebula.

Visible to the naked eye, only 1500 light-years from Earth, the great Orion Nebula has been known and revered since ancient times.

A popular target of Hubble, researchers have now identified 42 new discs within it that could be the beginnings of new planetary systems like our own.



14-Dec-2009: A collection of 30 never-before-released images of embryonic planetary systems in the Orion Nebula are the highlight of the longest single Hubble Space Telescope project ever dedicated to the topic of star and planet formation.

Also known as proplyds, or protoplanetary discs, these modest blobs surrounding baby stars are shedding light on the mechanism behind planet formation. Only the NASA/ESA Hubble Space Telescope, with its high resolution and sensitivity, can take such detailed pictures of circumstellar discs at optical wavelengths.

Looking like a graceful watercolour painting, the Orion Nebula is one of the most photogenic objects in space and one of the Hubble Space Telescope's favourite targets. As newborn stars emerge from the nebula's mixture of gas and dust, protoplanetary discs, also known as proplyds, form around them: the centre of the spinning disc heats up and becomes a new star, but remnants around the outskirts of the disc attract other bits of dust and clump together.

Proplyds are thought to be young planetary systems in the making. In an ambitious survey of the familiar nebula using Hubble's Advanced Camera for Surveys (ACS), researchers have discovered 42 protoplanetary discs.

Visible to the naked eye, the Orion Nebula has been known since ancient times, but was first described in the early 17th century by the French astronomer Nicolas-Claude Fabri de Peiresc — who is given credit for discovering it. At 1500 light-years away, the nebula, also known as Messier 42, is the closest star-forming region to Earth with stars massive enough to heat up the surrounding gas, setting it ablaze with colour, and making the region stand out to stargazers.

Hubblecast features news and Images from the Hubble Space Telescope (HST).

The space-based observatory is a collaboration between NASA and ESA. The observations are carried out in visible, infrared and ultraviolet light. In many ways Hubble has revolutionised modern astronomy.

The Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy. From its vantage point 600 km above the Earth, Hubble can detect light with "eyes" five times sharper than the best ground-based telescopes and looks deep into space where some of the most profound mysteries are still buried in the mists of time.

The 2003 BBC documentary "The World's First Time Machine", directed by Ben Bowie and featuring Ronald Mallett, premiered in the USA on The Learning Channel on December 3, 2003. This documentary features some of Dr. Mallett's current time travel research. It has since been shown numerous times on The Science Channel.

Ronald L. Mallett, PhD is a professor of theoretical physics at the University of Connecticut. He discovered a possible way to travel in time by applying Einstein's theory of relativity to laser light moving in a circle. The program uses CGI to illustrate his theories. Mallett was one of the first African-Americans to obtain a PhD in theoretical physics. He was inspired to do so because he wished to travel back in time to visit his dead father, who died when Mallett was ten.

HG Wells did it by means of an armchair and a cut lead crystal handle. The Starship Enterprise does it by unfeasibly powerful engines. And Doctor Who managed it in a 1960s police box, of all things. But just what is the truth behind time travel -- does modern day physics allow such a venture?
