AI Thread Summary
The discussion focuses on the classification and naming conventions of NGC and IC objects, detailing types such as G, GiP, GiG, and PN, with examples provided for clarity. Users seek databases that list common names for these objects, with links to resources like the NGC/IC Project and SEDS mentioned as useful. The conversation highlights the distinction between Otype and Mtype classifications, referencing Hubble's classification system. A participant notes their long-term ownership of a printed NGC catalog, emphasizing the depth of the subject. Overall, the thread serves as a resource for identifying and understanding NGC/IC object classifications and names.

How o you find the Names of the types of NGC/IC objects:

Classifications: G, GiP, GiG, PN, EmG, ISM, Sy2, rG, IG, etc.

ex. PN = Planetary Nebula

Also is there a database that contains the Common Names of these NGC/IC objects:

ex. Pinwheel Galaxy or Blue Snowball Planetary Nebula.

These give some galaxies but do not explain Otype and Mtype. Otype classifications are G, GiG,GiP,EmB,etc. Mtype classifications are Hubble's classes: Sa,Sab,SB,SAB,E,etc.
 

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?'

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...
