![]() You are saying 'IF I do this.' - which is the experimental portion- that 'THEN this will happen'- which is the prediction or 'educated guess' portion. However, yes the best way is to write an if/then statement, because it is formatting your prediction in a very testable way. One of the things that we must be careful when writing a hypothesis is that we should not make it a conclusion (an actual 'statement'!) for instance, "Red apples cause pimples." is a conclusion that could be obtained from an experiment, while "Red apples may cause pimples" might be a hypothesis. Yes, an if/then statement is a very safe way to write a hypothesis. There is no accurate way of measuring if people think that red apples are attractive. I think usually non-testable hypothesis are something that are not exactly 'measurable' or 'observable', such as "Many people may think that red apples are attractive". Like the article says, a hypothesis must be testable, meaning we can do experiments with it to see if it is supported or not. "It is a large, luminous galaxy at z = 4.05 involved in a short and massive starburst centered in the stellar nucleus and extended over the entire galaxy, out to radii of 4 kpc, and likely induced by the interaction or merger with a member of the proto-cluster," the researchers explained.I think that there is no definite format to writing a hypothesis, but as you said, yes there is a 'proper' and appropriate way to writing a hypothesis. Summing up the results, the authors of the paper noted that GN20 has all the properties needed to evolve into a massive quiescent galaxy at intermediate redshift. Moreover, the astronomers found that the stellar nucleus appears to have the highest concentration of cold dust but not the largest concentration of molecular gas. This offset may be a result of a recent gravitational encounter or merger.īy analyzing the JWST images, the team also identified additional faint stellar clumps that appear to be associated with some of the ultraviolet and carbon monoxide-clumps. The work combined decades-old data from Voyager 2 with newer observations of other potentially watery moons. The stellar envelope has an effective radius of about 11,740 light years, and its position agrees with that of the carbon monoxide molecular gas, but its centroid is offset by approximately 3,300 light years from the stellar nucleus. The nucleus is less than 2,600 light years in size, carries 9% of the total flux and coincides with the compact, cold dust nuclear emission. This stellar structure is forming new stars at a constant, high rate of about 500 solar masses per year, for a period of 100 million years. The observations found that GN20 has a stellar structure characterized by a luminous (with an absolute magnitude of -22.35) unresolved nucleus and a diffuse extended envelope. "GN20 JWST imaging was obtained on November 23–24, 2022, using the MIRI imager (MIRIM, Bouchet et al, 2015) in the F560W filter as part of the European Consortium MIRI Guaranteed Time (program ID 1264)," the researchers explained. For this purpose they used JWST's Mid-Infrared Instrument (MIRI). ![]() Recently, a group of astronomers led by Luis Colina of the Spanish Astrobiology Center in Madrid, Spain, decided to perform mid-infrared observations of GN20, aiming to shed more light on its properties. The molecular gas distribution in this galaxy shows a clumpy stellar structure with a diameter of approximately 45,600 light years and kinematics consistent with that of a massive rotating disk. GN20 is located in a protocluster or galaxy overdensity, has an infrared luminosity of some 18.6 solar luminosities, and a star formation rate (SFR) of about 1,860 solar masses per year. At a redshift of 4.05, GN20 is one of the most luminous dusty star-forming galaxies (DSFGs) known to date.
