• 16:3816:38, 26 April 2021 diff hist +218 Industrial gas →Gas production technology: Hydrogen production is by no means carbon-free. Its production requires tremendous amount of energy compared to energy coming from hydrogen itself. By far it's just a hype. Tag: Visual edit

• 23:2223:22, 23 March 2021 diff hist +11 Advection Added the notion of a fluid to make it easier to quickly understand the nature of advection. Tag: Visual edit

• 22:2222:22, 9 January 2021 diff hist +18 Europa (moon) →Surface features: Changes to avoid confusion with Earth Day Tag: Visual edit
• 14:5414:54, 9 January 2021 diff hist +342 Europa (moon) →Surface features: Added clarification. Radiation exposure is calculated for Earth day which may be somehow misleading as one may think that by "day" we mean Europan day which isn't the case. Tag: Visual edit

• 08:4008:40, 3 January 2021 diff hist +266 Iron →Cosmogenesis: I've just added one more source - it's Ia, not II that produce and scatters iron. Tag: Visual edit
• 08:1908:19, 3 January 2021 diff hist −110 Iron →Cosmogenesis: Even further refined this section. Type II crushes iron into neutron star or a black hole. It is Ia that violently unbinds itself with all heavy elements
• 08:0408:04, 3 January 2021 diff hist −85 Iron →Cosmogenesis: Please do not revert to type II supernova. It's a type Ia supernova that scatters iron in space, not type II. Please read the source provided. Tag: Visual edit: Switched
• 07:3807:38, 3 January 2021 diff hist +19 Venus →Physical characteristics: Added surface temperatures conversions to °C and °F from kelvins Tag: Visual edit
• 07:3507:35, 3 January 2021 diff hist +69 Venus →Atmosphere and climate: More on supercritical atmosphere Tag: Visual edit
• 03:2103:21, 3 January 2021 diff hist +229 Venus →Physical characteristics: To my surprise supercriticality of Venusian atmosphere was not mentioned Tag: Visual edit

• 08:2508:25, 15 November 2020 diff hist −1 m List of police-related slang terms →F: "Slide" instead of "slot" - dictionary...
• 08:1908:19, 15 November 2020 diff hist +130 m List of police-related slang terms →F: Someone outside the U.S. recently asked my what the Five-O is, so I decided to expand the description a bit. Tag: Visual edit

2 October 2020

• 03:2403:24, 2 October 2020 diff hist +280 Iron →Cosmogenesis: Added source to cosmogenesis Tag: Visual edit
• 03:1303:13, 2 October 2020 diff hist +110 Iron →Cosmogenesis: Only type Ia contributes because it physically unbinds the star. Type II, as it was previously in this article, collapse directly into the neutron star or a black hole, crushing the vast amount of iron into degenerate matter. Tag: Visual edit
• 02:1602:16, 2 October 2020 diff hist +45 m Iron Added possibly a useful link to elements abundance Tag: Visual edit
• 02:1002:10, 2 October 2020 diff hist +62 m Iron Minor change, just to give folks an idea how much oxygen there is on Earth Tag: Visual edit

• 20:2920:29, 29 July 2020 diff hist +183 Triple-alpha process →Reaction rate and stellar evolution: Added source Tag: Visual edit
• 20:1720:17, 29 July 2020 diff hist +25 Triple-alpha process →Reaction rate and stellar evolution: Fixing a typo and rephrasing
• 20:1320:13, 29 July 2020 diff hist +359 Triple-alpha process →Reaction rate and stellar evolution: Added helium-burning stage. Luminosity also drops dramatically
• 19:5619:56, 29 July 2020 diff hist +46 Triple-alpha process →Reaction rate and stellar evolution: Helium flash's energy is by no means attenuated by overlying layers. The whole energy goes to lift up the core to dense but gaseous state, that's why from our perspective it's a dud to watch

• 14:5114:51, 26 July 2020 diff hist +204 m B-type main-sequence star The depiction of a typical B V star was somewhat misleading, with the primary being heavily evolved giant. Added a clarification, so folks would probably find the proper, B main sequence star easier
• 14:3014:30, 26 July 2020 diff hist +18 m B-type main-sequence star →See also: To make life a bit easier

15 July 2020

• 04:1904:19, 15 July 2020 diff hist +69 GW170817 →Scientific importance: To elaborate what Edo Berger said, r-process was attributed exclusively to SN explosions prior to that event
• 03:3003:30, 15 July 2020 diff hist +20 Chandrasekhar limit →Tolman–Oppenheimer–Volkoff limit: Added link to stellar remnant
• 03:1903:19, 15 July 2020 diff hist +77 Chandrasekhar limit →Tolman–Oppenheimer–Volkoff limit: N/A to aftermath of Ia explosion

• 21:5821:58, 17 June 2020 diff hist +7 Strontium →Applications: I think using a past tense is now closer to the reality since CRTs are being phased out even from industry applications
