This Tuesday's Twitter recommendations share the day, because they are similar type accounts.
@astrotweeps has a different astronomer/planetary scientist tweeting each week about their area of research and what they find interesting. I end up following many of the guest tweeters.
@realscientists is curated by a different scientist/writer/artist/clinician some still working on achieving their PhD's. Warning, I did mute them the week that the entomologist was showing all kinds of freaky pictures.
Check them out - you may learn something and find new interesting people to follow!
