Jodrell Bank Observatory's Meteor Detector

Expand (144kb, 900 x 692)

One of the first experiments carried out by physicists at Jodrell Bank in 1945 was the detection of echoes from meteors by the reflection of radio waves. Lovell and his colleagues used ex-Army radar equipment working at a wavelength of about 4-m to detect the reflections from the ionised trails left over in the upper atmosphere by these little particles of rock.
The current meteor detector was constructed in April 2007 and picks up reflections from a television transmitter in Spain (which transmits at 48.25 MHz), far enough away that normally we can't receive the signal at all. When one of these ionised trails is created in the upper atmosphere, it can reflect the signal in our direction and we hear an echo.

Oranges Are Not The Only Fruit

The youngsters find a mysterious old glass bottle which leads them on a strange and magical adventure, while the nearby Jodrell Bank telescope picks up curious signs and leads the children and a local author to suspect a dragon could be at large.
The drama has been made by Lime Pictures, the makers of Channel 4 soap Hollyoaks, and will be shown on BBC1 later in the year.

Veteran British scientist Sir Bernard Lovell has revealed that the Russians tried to kill him during the Cold War of the 1960s.
Professor Lovell led the construction of the Jodrell Bank Radio Telescope which tracked the USSR's Sputnik satellite - the first in the world - when it was launched in 1959.
In a TV interview Sir Bernard confirmed that the Jodrell Bank was then used as the first "early warning device" of a Soviet nuclear attack.

The first stage of the switch-on of one of the world's most powerful stargazing systems has got under way.
Seven radio telescopes around the UK have been linked with optical fibres, allowing scientists to probe deeper into the Universe than ever before.
The new data-link upgrade has replaced the older microwave technology that once connected the telescopes.
