    Supernova System
AI Thread Summary
Reliable supernova alert systems are limited, particularly for distant supernovae, as SNEWS primarily detects those in our galaxy using neutrino signals. While SNEWS provides early detection, its range is restricted due to the nature of neutrinos. Users are seeking comprehensive alert systems that notify them of all supernova events, but current options like CBAT come with costs and cover various transient phenomena. The effectiveness of a 20-inch telescope for observing supernovae can also be impacted by light pollution and location, making it crucial to consider these factors. Overall, there is a demand for a more universal alert system for supernovae that caters to both amateur astronomers and researchers.

I was wondering if there are any reliable Supernova alert systems, where they notify me as soon as a supernova happens. I have a 20 inch telescope, and I have SNEWS installed. However, since SNEWS is only a detection for nearby galaxies, I was wondering if there is any alert system for supernovae that applies to everything. I just want an alert system that tells me to jump on my telescope as soon as a supernova occurs. I'm actually a student doing a research project, and I'm looking to run to observatory as soon as a supernova happens. I'm trying to make a light curve for it and make it as complete as possible. I know that there's lists of recent supernovae that update once in a while, is there anyway to keep updated on all supernovae?

I hadn't heard of SNEWS, but according to the site it is only for supernovae in our galaxy. I don't think early detection is reliably available for more distant ones.

The entire point of SNEWS is to use the neutrino signal to pinpoint the supernova before it is visible in the electromagnetic spectrum. This of course has a limited range because of how sensitive neutrino detectors are.

Edit: Or rather, how non-interactive neutrinos are...

thanks guys! Understood!
 
There's CBAT, but a) it costs money and b) publishes all sorts of transient phenomena.

Also, a 20" may not be useful, depending on where you are located. You'll get a magnitude 15 event every few weeks. Depending on the light polution, this could be tough.
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
