===Deep-sky objects===
Of the [[deep-sky object]]s of interest in Vela is a [[planetary nebula]] known as [[NGC 3132]], nicknamed the 'Eight-Burst Nebula' or 'Southern Ring Nebula' (see accompanying photo). It lies on the border of the constellation with Antlia.<ref name="motz"/> [[NGC 2899]] is an unusual red-hued example. This constellation has 32 more planetary nebulae.

The [[Gum Nebula]] is a faint [[emission nebula]], believed to be the remains of a million-year-old supernova. Within it lies the smaller and younger [[Vela Supernova Remnant]]. This is the [[nebula]] of a [[supernova]] explosion that is believed to have been visible from Earth around 10,000 years ago.  The remnant contains the [[Vela Pulsar]], the first [[pulsar]] to be identified optically. Nearby is [[NGC 2736]], also known as the Pencil Nebula.

[[HH-47]] is a [[Herbig-Haro Object]], a young star around 1,400 [[light-year]]s from the Sun that is ejecting material at tremendous speed (up to a million kilometres per hour) into its surrounds. This material glows as it hits surrounding gas.<ref>{{cite web|url=http://www.almaobservatory.org/en/press-room/press-releases/632-alma-takes-close-look-at-drama-of-starbirth|title=ALMA Takes Close Look at Drama of Starbirth|last=Foncea|first=Valeria|author2=Arce|author3=Héctor|date=20 August 2013|work=Atacama Large Millimeter/Submillimeter Array|access-date=11 October 2013|archive-url=https://web.archive.org/web/20130927154903/http://www.almaobservatory.org/en/press-room/press-releases/632-alma-takes-close-look-at-drama-of-starbirth|archive-date=27 September 2013|url-status=dead|df=dmy-all}}</ref>

[[NGC 2670]] is an [[open cluster]] located in Vela. It has an overall magnitude of 7.8 and is 3,200 light-years from Earth. The stars of NGC 2670, a Trumpler class II 2 p and Shapley class-d cluster, are in a conformation suggesting a bow and arrow. Its class indicates that it is a poor, loose cluster, though detached from the star field. It is somewhat concentrated at its center, and its less than 50 stars range moderately in brightness.{{sfn|Levy|2005|p=87}}

Located 2 degrees south of Gamma Velorum, [[NGC 2547]] is an open cluster containing around 50 stars of magnitudes 7 to 15.<ref name="motz">{{cite book|last=Motz|first=Lloyd|author2=Nathanson, Carol |title=The Constellations: An Enthusiast's Guide to the Night Sky|publisher=Aurum Press|location=London, United Kingdom|year=1991|pages=381–83|isbn=978-1-85410-088-7}}</ref>

[[NGC 3201]] is a [[globular cluster]] discovered by [[James Dunlop]] on May 28, 1826. Its stellar population is inhomogeneous, varying with distance from the core. The [[effective temperature]] of the stars shows an increase with greater distance, with the redder and cooler stars tending to be located closer to the core. As of 2010, is one of only two clusters (including [[Messier 4]]) that shows a definite inhomogeneous population.<ref name=aaa512_L6>{{citation | display-authors=1 | last1=Kravtsov | first1=V. | last2=Alcaíno | first2=G. | last3=Marconi | first3=G. | last4=Alvarado | first4=F. | title=Evidence of the inhomogeneity of the stellar population in the differentially reddened globular cluster NGC 3201 | journal=Astronomy and Astrophysics | volume=512 | page=L6 |date=March 2010 | doi=10.1051/0004-6361/200913749 | bibcode=2010A&A...512L...6K | postscript=. |arxiv = 1004.5583 | s2cid=118407774 }}</ref>

[[RCW 36]] is a star-forming region in Vela, and one of the nearest sites of massive star formation. This star-forming region has given rise to a cluster of several hundred young stars that power an HII region.<ref name="Feigelson2013">{{Cite journal | last1 = Feigelson | display-authors = etal | year=2013 | title = Overview of the Massive Young Star-Forming Complex Study in Infrared and X-Ray (MYStIX) Project | journal = The Astrophysical Journal Supplement Series | volume = 209 | issue = 2 | pages = 26 | doi=10.1088/0067-0049/209/2/26 | arxiv=1309.4483 | bibcode=2013ApJS..209...26F| s2cid = 56189137 }}</ref> The star-forming region lies in Clump 6 in the [[Vela Molecular Ridge]] Cloud C.<ref name="Yamaguchi1999">{{Cite journal | last1 = Yamaguchi | display-authors = etal | year=1999 | title = A Study of Dense Molecular Gas and Star Formation toward the Vela Molecular Ridge with NANTEN | journal = Publications of the Astronomical Society of Japan | volume = 51 | issue = 6 | pages = 775–790 | doi=10.1093/pasj/51.6.775 | bibcode=1999PASJ...51..775Y| doi-access = free }}</ref>
