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.

Sub: Comprehension

One needs to understand Cosmic function of the Universe -through origins-Cosmology Vedas interlinks. Concentration, meditation and Dedication are the keys for progress Index. otherwise it boils down t wild-goose chase of terminology-Undefined Universe in search of chaos or justification. This psychology is not a good trend for scientific community-Vidyardhi Nanduri

I have grasped. Girl with big... red flowers talks about their xxx-rays.

@zargone9

She is a useless presenter. Find someone who can act naturally in front of a camera. Im sure she is a great scientist, but this is about presentation for an audience. I am into acting, and therefore notify small nuances in her behaviour.

@askjiir : Rebecca Barnes is an accredited working member of the High Energy team at ESA. What the hell are you doing right now?

[brian4480]

@askjiir why?

[askjiir]

I recomend Spacerip channel if you want profound quality, astronomy documentaries. Not sugarcandy ones like these, that get likes because you want to fuck the purposely placed, sexy woman that read her lines from text on the camera screen.

@brian4480

Disagreed.

[askjiir]

She is distracting. GTFO woman, im trying to focus on science here, not your cutsie face.
