I wanted to see the definition to find out what the values were for Venus and Mars:
https://en.wikipedia.org/wiki/Earth_Similarity_Index
Turns out Venus is at 0.444 and Mars is at 0.697 so 0.98 is really close.

#13Here are some other planets we've found with comparable similarity. Note that earth-like similarity does not imply that it is habitable.

#15As of now, the content linked says nothing more than the PR announcement from yesterday -- so either the title is misleading, or the OP comes from the future. (I'm aware he might have other sources for the title, but it's still misleading)
I think the announcement is live at noon today (EST).
You probably mean EDT, just FYI.

Thanks for sharing that. I've been looking for something like this. Traveling and juggling meetings in multiple timezones is a big source of anxiety for me. I'm always wondering if I did the math wrong or if there is a daylight savings I haven't accounted for.

#18Searching google news for "earth similarity index" gives me no indication that NASA will make this specific announcement.
Is there a source? If not, it makes sense to change this title to "NASA to make announcement that 'astronomers are on the cusp' of finding 'another earth.'"

#19It's crazy to think that there may be life everywhere in space and incredible things we haven't seen yet, that our mind can't even conceive.

Indeed, "earth similarity" should not be taken as "potential habitability", if Earth's unique geological history (the Theia collision) means that it is at the lower bound of mass for a habitable planet. Already there are super-Earths discovered.
