    Galaxy Supernova
AI Thread Summary
The recent supernova in the Pinwheel Galaxy has sparked interest among amateur astronomers, particularly those experimenting with imaging techniques. One participant shared their efforts to capture the galaxy, noting challenges with weather and color balance in their photos. They expressed excitement about the possibility of discovering a supernova, indicating that unusual color patterns in stars could signal its presence. Additionally, a mention of an amateur astronomer who unknowingly recorded the supernova highlights the significance of such discoveries in the field. Overall, the discussion emphasizes the blend of amateur astronomy and significant cosmic events.

Holy cow, I've been working on imaging that galaxy while experimenting with my equipment. Weather didn't cooperate last night, bit I was planning to try again tonight. Discovering a supernova would be awesome, but I'm not sure I would notice, lol.

On second thought, there's a decent chance I would have noticed. One of the issues I was working on/experimenting with is color balance/exposures. My result is below (similar orientation as the discovery photo), which has some weird color artifacts in overexposed stars. Since I was working on that and since I shot different colors on different days, I likely would have noticed an oddly colored star, showing up in red and green but not blue, for example.

And here's a clip of a single subframe I just took with a different scope, with the supernova still visible/circled:

So, are you going to measure the light curve?
 

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...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
