Gaia - what a telescope!

It's clear to me that ESA's Gaia spacecraft is going to be one of the most productive scientific missions ever.
In the 4 years it's been 'in service' it's measured the position in 3 dimensions of 1.7 Billion stars, equivalent to over 14 per second.
The motions of stars has been measured as well, including stars out as far as the Magellanic Clouds.

The most recent S@N TV programme gave a superb overview of the ...

Star Disk

While taking a short break in the Peak District National Park, I came across this 'star disk' or planisphere high on a hill overlooking the town of Wirksworth.

Each of the seats represent a viewing date and time as on a conventional planisphere. The weather wasn't so good, with rain threatening, but well worth the hike up to the top of the hill. I very quickly spotted a mistake! Actually I rather like the ...

I was looking through some old Sky at Night stuff and found my sons and I at the 50th Anniversary do at Patricks of the LIVE Sky at Night.

When I was nine years old my Mother

When I was nine years old my Mother dragged me to Gurnsey for a week to visit friends that I had never seen before or since ?

However, whilst there she bought me my first telescope, I remember it to this day, with a terrible telescopic tripod that extended all of 3 feet. I, and the rest later went into the garden to look at the Moon.

Amazing, found a MINT one last week for ...

Back with a new scope!

It's been a while since I was here, but I'm coming back into Astronomy with a new scope (a very early Father's Day pressie)
I can't accommodate a big scope, and there's no way I'm leaving a big expensive scope out in the garden round here. So I decided on a little spotter, an Orion GoScope III 70mm. I currently have a 75mm spotter but its a birding scope and only has a 27x eyepiece. ...

The Space Elevator and Sun's gravity

I was wondering if the space elevator ever was constructed would it be able lift very heavy objects off the earth.

As far as I know there comes a point far away from the earth where the earth's gravity is too weak to hold onto objects and the sun's gravity kicks in and begins to pull the object towards itself. If the space elevator cable was super long, could it be extended so far that ...

Mars images from Spirit, Opportunity and Curiosity

I am reaching out as part of a citizen science project sponsored by ESA called LabelMars.

Thousands of images of Mars taken by Spirit, Opportunity and Curiosity Rovers have been made available to the project.

We're looking for help from the community to label geological features within the images taken from these past missions. This will be used to form the basis future robotic exploration missions to Mars and also enable large-scale analysis of the ...
