comment Accidental or deliberate?
I don't know if the apparent size of the Sun and the Moon have anything to do with this, but this study claimed to have found that total solar eclipses have a positive effect on the microbes studied.

comment Stellar mass database
Sol Station has stellar mass info as well as distance. Look especially under the "Stars within 100 ly" section. Is this to the level of precision you need?

comment What is the next planned mission that can discover life on another planet?
I cannot find any reference to InSight being used for this purpose, though it seems a good candidate. The ExoMars rover will do some shallow digging for this purpose.

comment Stellar mass database
How far out do you need to consider? 50 ly? 100? 1000?

comment Does a week represent something in astronomy?
Sure, I suppose it is on topic since it relates to the planets.

comment Does a week represent something in astronomy?
The duplicate post has some better information in its answer related to the significance of the quarters (they line up roughly with the phases of the lunar cycle).

comment Does a week represent something in astronomy?
Andy, the Wikipedia article Keith Thompson linked says there is no evidence that the connection between the seven days of the week and the seven classical planets goes back to the original Babylonian establishment of the seven-day week.

comment Are space telescopes completely out of the earth's atmosphere?
What do you mean by "every other telescope"? What about this? Or this? The Hubble telescope is roughly in the exosphere which is not a complete lack of atmosphere but is nevertheless exceedingly thin.

comment If nothing can pass the schwarzschild radius, how can black holes even start?
Every mass has a Schwarzschild radius, only black holes have an event horizon.

The Schwarzschild radius and event horizon are not the same thing. That is probably the source of your confusion.

comment What are Wolf - Rayet stars?
Sriram, it would help if you could clarify a little bit what you don't understand about Wolf-Rayet stars. If you're having trouble forming a question, try reading the Wikipedia article or the Simple English Wikipedia article.

@userLTK This should probably be an answer.
