It's all about error correction according to this news. They're betting on their new qLDPC error-correction codes being significantly more efficient than other approaches. Starling is planned to be built in 2029. Is this a genuine

What caught my eye about this article is the claim that they're achieving this with a more accessible setup. Using an algorithm to interpret and reconstruct a view based on light coming off a surface is quite brilliant I think! What ar

There has always been a huge problem for SETI in my opinion, the size of the area to scan. The sky is huge and so much is out there! It never really occurred to me that we might have already recorded something interesting and just missed it

"The interpretation of dolphin communication, alongside the vocalizations of humpback whales and broader aspects of non-human communication, is increasingly garnering attention from SETI researchers and astrobiologists." Do you th

You are completely right mcdeltat. The problem with writing content is that without feedback it is easy to forget or miss something, even if it appears to be very obvious to you sometimes it is just too easy to miss. A webpage needs to be c

I am a real person and some of those comments sting! believe it or not I will try to improve and am doing my best documenting my journey and all that have learnt in astrophotography.

Instead of using the more expensive software such as Pixinsight which costs at least 300 Euros, I try to use free software where possible. I do use Photoshop a little which is not free but not expensive either. I have used many techniques i

What are the leading theories for how these early galaxies achieved this so efficiently? Is it purely down to the sheer number of UV photons from the first massive stars, or are more exotic mechanisms (like early quasars or dark matter inte

Just read up about the airy disk. That's quite interesting. Seeing can be such a complicated subject and so much maths is involved in astronomy. When I deal with the subject, I always try to simplify things and get away from the maths.

Most people think better telescopes or cameras are the key to sharper astrophotography, but there’s a hidden culprit that often matters more: “seeing.” I always wondered why, on some nights, even the best gear produced blurry, shimmering im
