Astrophysicists have discovered two tiny, record-breaking planets that survived millions of years plowing through the broiling interior of a giant star.
Outside our solar system, "these are the smallest planets ever found, they are the least massive, " said University of Montreal astrophysicist Gilles Fontaine, who co-authored the study with an international team led by four of his former Ph.D students.
The planets KOI 55.01 and KOI 55.02 have radii about 0.76 and 0.87 times that of the Earth, the researchers reported online in the journal Nature Wednesday.
That makes them slightly smaller than two planets billed by NASA earlier this week as the smallest ever found.

So, does two tiny planets mean the possibility of several tiny moons, or did the dwarf star maybe just "eat" any moons that might have been with the two tiny planets? :biggrin2:

Chris, it is just stuff like this that "shouts out" how so very little we actually know about anything exo-Earth. We look (into the past) with various types of telescopes! We listen (into the past) with various radio and signal gathering instruments, and we send explorer type craft toward the "near" reaches of our solar system and galaxy. But, we just don't know much, about our own little backyard solar system, much less about the wonders of our universe.

We have only just begun! What the future holds for us, in this regard, remains an interesting contemplation.

"plowing through the broiling interior of a giant star"
I would have thought they'd incinerate. :yikes:
Must be made of tough material!

Chris,

THIS IS DIRECT OBSERVATIONAL VINDICATION OF SNOWBALL SOLAR SYSTEM.

Snowball Solar System (SSS) suggests that our sun formed as a binary star which merged in a luminous red nova (LRN) at 4.567 Ga, and the red giant phase of the LRN enveloped the inner terrestrial planets, resulting in their volatile depletion.

Originally, Venus and Earth may have formed like the ice giants Uranus and Neptune before their complete immersion in solar plasma during the red giant phase of the sun, resulting in the 'planetary volatility trend' and their formation of metallic-iron cores.

SSS is the greatest paradigm shift since the Copernican Revolution of 1543.

... or pulled into the star.

Binary Star Systems must be pretty complex. Just look at our true Solar System's movements.

Thats the simple explaination, now if you have time for some light reading then there is this:

Seems to me that the complexity of solar system development and planetary movement is still a developing science.

The more we understand, the more we realize we don't know it all. And the gap continues to grow.
