Peggy is something along the edge of Saturn’s ring, a glitch whose source we’ve never seen. Cassini took a last peek at Peggy during its Grand Finale destructive plunge, adding a final piece to the puzzle for future researchers to pour over when trying to understand this mysterious disturbance. 27-year Cassini project veteran Carl Murray of Queen Mary University of London recalls his first sighting of the ring glitch, in early 2013.
Yesterday morning, NASA’s Cassini spacecraft slammed into the day side of Saturn, the brief flash of its vaporization marking the end of a 13-year mission. But it took people to turn this hunk of aluminum and silicon into an extension of our curiosity. For the past three days, I’ve chatted with engineers and scientists at the wooden tables dotting Jet Propulsion Laboratory’s pedestrian mall, and in the sage-scented gardens surrounding Caltech.
In its final look around the Saturn system, the Cassini spacecraft captured one last image of the propellers nestled in the outermost part of the main rings. These beautiful patterns show up when tiny moonlets disturb the material of the rings. But they’re not just nice to look at – they also offer clues to how planets form. In these images, “the moon is as small as a pixel, so we don’t really see it”, says Matthew Tiscareno at the SETI Institute.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Obama AND Romney or Obama + Romney.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used.) For example, search for democrat OR republican to find results that refer to
Democrats and/or Republicans.
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
