Cathartic

Weird I know. I like the idea that I’m helping these scientists. Looking at 3 static images over and over also helps my mind not race. I have no idea if I’ll ever get feedback on if I correctly identified a black hole but it’s not a big deal for me. You guys are busy unlocking the secrets of the universe and this app probably isn’t top priority XD

Anyway! Thanks for letting me be a part of this

Response from developer

Thanks for the nice review! Yes, the people behind this app are quite busy, that is why they asked for your help. Every classification is a valuable piece of information that potentially could lead to discoveries.

Love These Citizen Science Things

Nemo ... has some excellent points. I just fired the app up this evening and it says there's nothing to analyze right now. Are we still engaged, or is my analyzing so bad that they don't want my help anymore? Anyway, hope there's more work in the future.

Response from developer

New transients are coming in again. Sometimes weather or technical issues from telescopes are a factor.

I'm an astronomer now!

This is my dream, I'm an astronomer now.

Being able to take part in this study to identify neutron star mergers is just amazing. This is the process where the gold in my wedding ring was created.

The app receives constant updates and using the app allows me to be a bit more productive in my idle time. It makes me feel like I'm aiding in discovering something new about our universe.

Needs Feedback

This app is a good idea: enlist people to help find kilanova in sky surveys by excluding non-astrophysical light sources. They train you with samples, BUT there is no feedback when you assess transients, and no sense what proportion are likely to be ‘real’.

I think when you mark ‘real’, you are just saying, ‘yeah, this is an astrophysical light-source,’ not ‘this is a kilanova.’ That would mean the ratio of real to bogus is much higher. But the app doesn’t make that very clear, so I select unknown quite a bit.

What would b great would be a quiz against a vetted set of transients. That way you could guess then see the correct answer. New quizzes every so often between actual assessments would be great. I don’t want to me incorrectly training the algorithm!!

Also, does the app need a certain number of ‘real’ selections on a given sample to be added to the real set, or is it just my assessment? Yikes!

I love the idea of supporting the effort; it feels meaningful. But a community, message board, quizzes, etc would go a long way in making me feel I am doing more good than harm.

Works as advertised

Not real exciting until you realize you’re looking at actual stars undergoing massive mind blowing changes.

FAQ

What is the main goal of Black Hole Finder?

The main goal of Black Hole Finder is to enable citizen scientists to help discover black holes, particularly those formed from the fusion of two neutron stars, by analyzing real-time telescope images.

How does Black Hole Finder contribute to scientific discovery?

Users analyze images from BlackGEM telescopes to spot fleeting light signals from cosmic events. This helps identify potential new black holes and contributes to research on gravitational waves and the formation of rare elements.

Can I get credit for my contributions to Black Hole Finder?

Yes, participants who make significant discoveries may be offered co-authorship on scientific publications resulting from their findings, recognizing their valuable contributions to the project.

What kind of training does Black Hole Finder offer?

The app provides training and guidance to enrich users' understanding of the cosmos and the processes involved in black hole formation. This helps users become more effective in their analysis and potential telescope direction.

What devices are supported by Black Hole Finder?

Black Hole Finder is available on iPhones, iPads, and iPods, allowing a wide range of users to participate in this citizen science project.

Is Black Hole Finder suitable for children?

Yes, Black Hole Finder has an age rating of 4+, making it suitable for younger users interested in learning about space and contributing to science.

How often is Black Hole Finder updated?

The latest version of Black Hole Finder is 4.3, and it was last updated on February 2, 2026. This indicates a commitment to ongoing development and improvements.

Does Black Hole Finder have ads?

No, Black Hole Finder is ad-free, allowing users to focus on the scientific analysis without any interruptions from advertisements.
