The cloud then re-emits this energy as microwaves.[4] These emissions were used to help redefine the Hubble constant.[5] References1. ^1 2 3 4 {{cite simbad|title=NGC 5765|accessdate=25 November 2017}} 2. ^{{Cite web|url=http://spider.seds.org/ngc/ngc.cgi?CatalogNumber=5765|title=NGC 5765|last=Frommert|first=Hartmut|website=spider.seds.org|access-date=2017-11-25}} 3. ^{{Cite news|url=https://scitechdaily.com/hubble-image-of-the-week-mcg01-38-004-and-mcg01-38-005/|title=Hubble Image of the Week - MCG+01-38-004 and MCG+01-38-005|date=2017-08-28|work=SciTech Daily|access-date=2017-11-25|language=en-US}} 4. ^{{Cite news|url=https://www.nasa.gov/image-feature/goddard/2017/hubbles-megamaser-galaxy|title=Hubble's Megamaser Galaxy|last=Hille|first=Karl|date=2017-09-01|work=NASA|access-date=2017-11-25|language=en}} 5. ^{{Cite web|url=https://www.spacetelescope.org/images/potw1735a/|title=From microwaves to megamasers|last=information@eso.org|website=www.spacetelescope.org|language=en-GB|access-date=2017-11-25}} External links{{WikiSky}}{{Sky|14|50|50.4|+|05|06|57|400000000}}{{Astronomical catalogs|NGC=5765}}{{Galaxy-stub}} 4 : Virgo (constellation)|Interacting galaxies|NGC objects|UGC objects |
