I find very interesting resources on astronomy and I would like to comment some of them.

"BHMS" provides students information step by step process of studying the stellar mass black hole candidates.
Using Stellarium directs them to plan observations and Faulkes Telescope provide them free access to robotic telescopes. Salsa J software that allows you to analyze and process astronomical images. Students must be familiar with SalsaJ.
This resource allows students using this hands on activities to feel researchers.

I was impressed by "Craters on Earth and other planets" and "Meteorites and their impact on the earth". This Inquiry Learning Space usе Down 2 Earth Calculator Impact that can simulate the impact of a certain size and density meteorite, which moves at a certain speed and trajectory under given angle. This program can then simulate the effects that follow. Students have the opportunity to work with very easy software to improve their knowledge of physics, astronomy, geography, as well as and the environment.

Very interesting is also "Galaxy classification and formation" resource. Students can investigate using of "Faulkes telescopes", SalsaJ and "Galaxy Crash" simulation.

Thank you for opening a thread about "Astronomy" and your contribution Tsetsa. 

Talking about Astronomy: Has anybody seen the planet alignment it is taking place from 20th January to 20th February 2016?

Have you talked about it in your classroom?

Do you think any of the ILS can help explaining this phenomena?

Dear Victor,

We started observations of the alignment of the planets in astronomical club two weeks ago. Students used Stellarium to determine the exact location of the planets.

By ILS in Go Lab can be used "Planetary Orbit Simulator", to explore how to get the arrangement of planets by studying with "NAAP planetary orbits Lab":
Another resource that can simulate the position of the planets is ILS "Planets". According to the pictures of this resource, you can see the position of the planets, using different dates. Unfortunately I cannot open the link:

Hello, thanks for this interesting discussion.

My students are very interested in astronomy, and I could notice it better when I asked them to choose their favourite contents to learn about using GO-LAB.

In my school we also have Stellarium to simulate astronomical observations from Earth, but I like better Celestia because it can explore space starting from anywere.

I prepared some activities for students with Celestia, but unfortunately my students can't read much english and all they can do is in italian.

After the gravitational waves discovery, I asked a friend (who is an astronomer) for some links for students and he gave me the following:

Last year I made the italian ILS "Meteoriti" using the Down 2 Earth Impact Calculator, that has been used by my students and others.

In the last weeks, I tried to re-use it with a new students group and I made a copy of it in order to get new files apart from them made last year by the former users.

When I tried to check what new students have done, I found several .txt files that should contain observations, data, graphs, but I'm not able to read them.

I hope someone can help me with this, please let me know.

Thank you and best regards.

 Dear Daniela,

Thank you for sharing your experiance. I also use Celestia, but not so often.

I also created last year leson at ILS : Explorations of solar activity and sunspots. You can find here:

Maybe for you and your students will be interesting to have experiance with SalsaJ. You can find a lot of information at "BHMS" , but also at ODS portal:

1. Measurements with Salsa J:

2. Image properties with Salsa J:

3. Setting scales with Salsa J

You can learn about SalsaJ with moodle course in   Scientix portal :

This is my moodle course: How to use SalsaJ for measuring the dimensions of astronomical objects. You can find it at Italian language.

Look also for more information about IBSE at EU-HOU project: (

I think Victor can help you, but maybe you must send the link and scrinshot of web page.

Kind regards,

Tsetsa Hristova

Very interesting resourse related to Graviational wave you can find in Inspiring Science Education. Check it out here:

You can clone this scenario and  use it (don’t forget to login first) . Here is the link:

Hope this was helpful.

Kind regards,

Very interesting posts!!!


Even if my students have 9-10 years old, when we discuss about Sun, Earth and other planets of our solar system, thay become very enthusiastics and opened to stories about stars. Stellarium it was used for those lessons, but next we'll try Celestia, too.

Also, we appreciated the ILS about planets and about our Solar system: "Movement of planets and planetary configurations" by Tsetsa. Hristova. Also, very interesting and easy to use in primary grades, is the lab "Sun 4 all". Students could investigate the changes in the nature produced by movements of our planet.

Using the remote telescope they could get deeper in the space, exploring other space objects... Thank you, GO-LABs!

Dear Tsetsa,

Two great ILS that you are mentioned are great to use in a cooperation with planetarium activity.

Its great to do it in school or out of school activities (unformal education).

Unfortunetly, in Israel we dont have a lot astronomy classes in curriculum, so most of activities are out of achool activities in labs, science it great to involve GO-LABS activities in it.


Best regards,
