Mobile phone cameras are improving constantly. Here is a good shot of the moon taken a few days ago with a good mobile phone and our handmade 16'' telescope. Enjoy and share!

In this so endearing dates I share with you this photo taken yesterday of our sweet home we call "Milky Way". The trained eye will distinguish other two neighboring galaxies. Our planet is about to complete another turn around its ordinary star. These are about 4 543 000 000 turns so far. Congratulations to all and enjoy the next turn.

Finding Cheap Airport Parking with Parkhero

As there are so many different airport parking options across the UK, it can be quite difficult at times to find the best price. The cost of parking varies depending on the how far ahead you book, the demand for parking when you leave on your holiday and the type of parking you are looking for. However, there is more to consider than price alone! The are three main types of parking at airports across the UK – Park and Ride, Meet and Greet and Park and Walk. You also need to consider whether you want an official service provided by the airport or an off-site provider. These will offer slightly different services, but the main difference is the distance from the terminal.
Using an online parking comparison platform, such as Parkhero, can help you find the best available options. Whether you want parking near Manchester Airport, Leeds Bradford, Gatwick or Bristol, Parkhero provides you with a simple overview to make your choice quick and easy. Best of all you do not get charged a bookin…
Happy to share with you this nice shoots we took during this week:

This one has been taken using a mobile phone and our powerful hand made telescope. The waning moon is rising up the pine trees situated about 15 km away. A few clouds on the horizon give a special interest to this picture.

This one is of our hand made telescope. In the background there are a few pine trees I was lighting with my front headlight during the 30 seconds exposure of the photography. This is a genuine picture. Nevertheless the post treatment of the foreground is slightly different from the post treatment of the background with the starry sky.

This one has been done yesterday. Despite of an apparently clear sky on the picture we actually had troubles with clouds yesterday. We finally had to go up to Roque Nublo (Center of Gran Canaria). The sky was clear there and we enjoyed a very good astronomy observation.

How many micrometeorites are falling in my garden?

Micrometorites are falling constantly everywhere. Their origin is unclear, according to some studies, most of them could come from comet dust. They are the oldest materials of the solar system. They are beautiful.

They are everywhere. On your doorstep, on your home roof, on your car roof. Any step you take outdoor, you step on many of them.

But you cannot see them. They are too small.

A very good question is : How many are they?

This apparently easy question is actually quite hard to answer. It depends on what you call a micrometeorite and what is your source of information. Next we are going to make an attempt answering.

The first definition of micrometeorites was actually only referring to unmelted particles. But in the last 20 years it happens scientist are calling micrometeorites to both melted and unmelted particles. Let us consider as "micrometeorite" any particle less than 1 mm in diameter coming from the space "as it" (not from a bigger body that broke up during…

Micrometeorites pretenders (all impostors)

We have been lastly trying to find more micrometeorites. In the South of Gran Canaria, it is almost raining during the winter only. At this time there are some roads near Mogan where the asphalt has not drained the rains for months. 

GC-605 road in South Gran Canaria
Many micrometeorites fell on this roads during this time. And they are still there.

Using an extremely powerful magnet it might be possible to find them. The magnet we have been using is a dangerous 1000 Kg powerful neodynium magnet.

1000Kg powerful magnet
We enfold the magnet in a plastic bag in an attempt to make easier to unstick metal particles from the magnet in the future.

Then we put the magnet under one of our minivan, separated about 8cm from the asphalt.

The magnet in place
We drove the GC-605 slowly and remove the magnet later. So far so good: it worked !

The harvest
With some difficulties we managed to separate the metal particles from the magnet. The power of the magnet attracting particles was much stronger than the p…

A very tiny one

At astroGCwe are dedicating time and money to find micrometeorites and learn more about this fascinating extraterrestrialspherules.

Micrometeorite hunting and their positive identification as extraterrestrial origin is challenging. Nevertheless micrometeorites are everywhere. Every step you take in an outdoor area, you step on several micrometeorites.

This means it is theoretically possible to find micrometeorites next to the door of your home. This is precisely what we have done.

On Saturday 6 April 2019. After a huge rain, we recollected dust on the sidewalk next to the garage where we are parking one of our vans.

We noticed a neighbor drains rainwater from his roof directly to the public sidewalk. It is not raining very often here. Micrometeorites fell on his roof during months and were moved out to the sidewalk during the strong rain. After analyzing the dust, we finally discovered a strong micrometeorite candidate. In this case we are not 100% sure it is a actually a micrometeorite. …
