In this series of blogs I have been exploring the different types of waves in the electromagnetic spectrum. I have written about radio, infrared, ultraviolet, gamma waves and x-rays. This blog finishes this topic with microwaves. The Cosmic Microwave Background (CMB) is radiation from around 400,000 years after the start of the Universe and thought … Continue reading Cosmic microwaves
We all know what gamma rays are don't we? They are the radiation that turned Bruce Banner into the Hulk. Ok so not strictly factual but gamma rays are radiation, part of the electromagnetic spectrum along with radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. French chemist Paul Villard was investigating radiation from radium in … Continue reading Gamma rays
One problem with traveling with multiple health issues is just getting comfortable. It's harder than you think. By way of explanation, I am a member of Blue Knights Law Enforcement Motorcade Club, and the European convention is taking place here in Rome. I am currently sat all alone in my room, while everyone else is … Continue reading This Roman holiday is agony
I have finally had enough! Enough of a job I never wanted. Enough of constant criticism. Enough of doing my best for the same people who drop you in the blink of an eye. When I took early retirement from the Police in 2014, I naively thought I could earn a little extra to top … Continue reading De-stressing art
Continuing in the theme of the electromagnetic spectrum from my last blog, what exactly is infrared and ultraviolet? The above picture was taken from the Nasa website and illustrates the different wavelengths of the electromagnetic spectrum. Infrared (IR) British astronomer William Herschel discovered infrared light in 1800, in an experiment to measure the difference in … Continue reading Infrared and ultraviolet
I don’t usually paint animals in watercolour, it’s the texture of the fur I struggle with. So this week I got my head down for a couple of hours and painted this fox. Overall it’s not too bad but a bit more practice is needed.
In my last blog I wrote about solar flares and how they can be deadly to unfortunate astronauts caught in their path. In order to predict these flares we use a superSID monitor, or rather lots of superSIDs working together. Solar flares occur when the suns magnetic fields cross paths and twist to the point … Continue reading X-ray classifications
A first look at todays offering. I am repainting a popular picture with a few changes. It is in 3 sizes 1/2 & 1/4 imperial and ACEO 3.5" x 2.5".
Previously I said that we could use our SuperSID monitor to detect changes in our sun by measuring the effects of intense X-ray bursts on the ionosphere. For millions of years, ever since the sun started its nuclear core, it has been emitting charged particles known as the solar wind. Our sun has settled into … Continue reading Danger danger Will Robinson
When I first started looking at radio astronomy I kept hearing about Super Sid. I had heard of Superman but not Super Sid, so who is he? Turns out superSID is a way of monitoring solar activity. SID stands for Sudden Ionospheric Disturbances, and a superSID monitor is used to look for these disturbances as … Continue reading Has anyone seen Super Sid?
A visit to Mansfield and Sutton Astronomical Society gave me opportunity to test out the portable radio telescope, pictured below. As you can see the arial is of a dish design mounted on a sturdy tripod. An equatorial mount allows the telescope to follow the arc of the target as the earth rotates. There is a … Continue reading A very basic test
There has been a slight gap between my last blog and this one. The purpose of this blog is to take me, as a total radio astronomy novice on a journey into the wonders I have been told exist out in the far depths of space. So why have I suddenly come to a juddering … Continue reading Yay I can see a blip on my monitor
