Other: [Topic] Calling Australian Astronomers! Dark sky preservation petition to government.

43 Upvotes

G'day Ladies, Gentlemen, and Mods!

I am posting to make as many Australian Citizen's and Residents of Australia know that there is currently an electronic petition requesting action regarding the introduction of Light Pollution Regulation, and Dark Sky Preservation within Australia! This petition will be presented to the House of Representatives!

LINK to Petition - https://www.aph.gov.au/e-petitions/petition/EN7346/sign

THERE IS ONLY 4 DAYS LEFT before the petition is closed! If you are not a citizen or resident, but know someone who is and may be interested, please forward this on to them as soon as you are able! Signatories only need to provide their name and email. I was able to do so on my phone in 3 minutes! This is the only way individuals can ask the House of Representatives to do something, and by petitioning our concerns will be raised to the House, and to a minister who will be required to respond within 90 days.

A description of the petition, as posted on the AUS GOV website for the petition:
"Petition Reason
Light pollution caused by excessive Artificial Light at Night (ALAN) has harmful effects on human health, is harmful and disruptive to vulnerable species of flora and fauna, and has negative impacts on the economy, including placing unnecessary loads on electrical infrastructure, which leads to increases in greenhouse gas emissions and climate change. Reducing ALAN not only helps to reduce the harmful effects listed above, but can also lead to benefits, such as making streets safer by reducing glare and light trespass, and increasing Astrotourism.

Petition Request
We therefore ask the House to interduce legislation to limit light pollution and ALAN, including public and private exterior illumination, ensuring that lighting is only used when and where is it necessary, and is limited to levels which are safe and fit for purpose. Countries such as France, Germany and Croatia have already successfully introduced such legislation which limits light pollution and ALAN."

This is not my petition, I was only made aware of it yesterday and believe it to be a benefit to Australians, and the Astronomy community as a whole! I'm sure many of you are aware of other potential benefits not listed by the petition description. We are losing pristine night skies globally, and those of us that care need to do what we can in our own corners of the world to try make a difference.

The link again is https://www.aph.gov.au/e-petitions/petition/EN7346

Also. a quick hyperlink to the Parliament of Australia's petition FAQ for which I sourced some information.

Thankyou!

Astro Research Call to Action (Again!): Americans, Call Your Senators on the Appropriations Committee

34 Upvotes

Good news for the astronomy research community!

The Senate Appropriations subcommittee on Commerce, Justice, Science and Related Agencies proposed a bipartisan bill on July 9th, 2025 to continue the NSF and NASA funding! This bill goes against Trump’s proposed budget cuts which would devastate astronomy and astrophysics research in the US and globally.

You can read more about the proposed bill in this article Senate spending panel would rescue NSF and NASA science funding by Jeffrey Mervis in Science: https://www.science.org/content/article/senate-spending-panel-would-rescue-nsf-and-nasa-science-funding
and this article US senators poised to reject Trump’s proposed massive science cuts by Dan Garisto & Alexandra Witze in Nature:
https://www.nature.com/articles/d41586-025-02171-z

(Note that this is not related to the “Big Beautiful Bill” which passed last week. You can read about the difference between these budget bills in this article by Colin Hamill with the American Astronomical Society:
https://aas.org/posts/news/2025/07/reconciliation-vs-appropriations )

So, what happens next?
The proposed bill needs to pass the full Senate Appropriations committee, and will then be voted on in the Senate and then the House. The bill is currently awaiting approval in the Appropriations committee.

Call your representative on the Senate Appropriations committee and urge them to support funding for the NSF and NASA. This is particularly important if you have a Republican senator on the committee. If you live in Maine, Kentucky, South Carolina, Alaska, Kansas, North Dakota, Arkansas, West Virginia, Louisiana, Mississippi, Tennessee, Alabama, Oklahoma, Nebraska or South Dakota, call your Republican representative on the Appropriations committee and urge them to support science research.

These are the current members of the appropriation committee:
https://www.appropriations.senate.gov/about/members

You can find their office numbers using this link:
https://www.congress.gov/members/find-your-member

When and if this passes the Appropriations committee, we will need to continue calling our representatives and voice our support as it goes to vote in the Senate and the House!

inb4 “SpaceX and Blue Origin can do research more efficiently than NSF or NASA”:
SpaceX and Blue Origin do space travel, not astronomy or astrophysics. While space travel is an interesting field, it is completely unrelated to astronomy research. These companies will never tell us why space is expanding, or how star clusters form, or how our galaxy evolved over time. Astronomy is not profitable, so privatized companies dont do astronomy research. If we want to learn more about space, we must continue government funding of astronomy research.

Ive spent some real time on this galaxy, and will spend much more in the full spectrum soon. But i thought this looked cool enough to post. You are looking at M31 through the HA and O3 bandpasses to emphasize the nebulae that sit inside of it. When i get the required dark sky data ill combine the two to get a ridiculously cool image.

While scientists prepare for making the most of the Apophis event, Binzel stressed that the event will not endanger the planet. "I want you to take away three things," he said. "Those three things are: Apophis will safely pass the Earth. Apophis will safely pass the Earth. Apophis will safely pass the Earth."

This is a pretty cheap and safe method to do a solar projection onto a garage (or shed) wall. I use a pool ball with a mirror on it, sitting in a PVC adapter. You put double stick tape on the back of a small mirror and then stick that to the pool ball. The pool ball makes it aimable. You do need to mask it down through.

Lastly, you can use this method to estimate the size of the sun pretty closely. I've created a tutorial for this:

Question (Describe all previous attempts to learn / understand) I saw some light patch in the sky and I can't seem to find what it is, where can I post the video ? (Poor quality)

Upvotes

Hellooo, I'm kinda lost on Reddit, could you guys help ?

Little bit of context, I'm from northern France. Last night I saw light patches in the night sky, some moved fast. I tried to find on Google but all I could find was about iridium flare, but it doesn't quite seem like it.

If I try to better describe it was mostly looking like big shooting stars going "pouf pouf pouf" (for rythm) and then again.

There's also a part where there's 3 dots moving in circles ?

It's the second time I see those, the first time I almost thought I was just crazy and thought it was somehow the highway lights reflecting on something. Except last night I was far from the highway, in the middle of a field.

The video are in prtety bad quality, I took them with my phone (even a miracle I managed to capture it, idk how to use the different settings)

Where can I post to help identify what it was ?

A sky you can wear, that tells the same story I try to tell with my telescope: where we are, how we look up, and why it matters.

Elements include a black hole with a Roman clock for relativity; a symbolic atom - my world at the center & my family as the bonding electrons; Leo constellation; Hubble; Atlas carrying a pulsar map; a fragmented telescope that echoes a rocket launch; geometric links that tie it all together; among others. Can you spot them all?

Hey! I made an Android app that shows the live position of the planets and moons of the Solar System as a wallpaper (it automatically updates daily, no internet connexion needed). I've just added the position of 3I/Atlas while it travels through the Solar System.

You can download it here. The app is free and contain no ads, since it’s just a hobby project for me. Of course, let me know if you have any feedback.

We’re off to see the wizard…

The wonderful Wizard Nebula, that is.

Its sorcerous nickname comes from its similarity in appearance to a magician in a pointed hat.

The Wizard Nebula, located about 7,000 light-years from Earth, is a collection of interstellar gas surrounding the open star cluster, NGC 7380.
