I would imagine that many observatories are underutilized and the funding would allow for increased utilization.

comment Real images (not “artist concept”) by NASA
@ispiro When I googled I looked specifically for "[mission/object name] photo database", for example "New Horizons photo database" or "Mars photo database".

Honestly, I just used google. You can also try googling with "site:nasa.gov" in your search query to get more refined results.

comment Does the Sun move?
This question is not a perfect duplicate of the linked question, but the answer lies either in the linked question or in What is in the center of the universe? that Tildal linked to.

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.

How far out do you need to consider? 50 ly? 100? 1000?

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 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.
