Wow, six planets in almost perfect resonance! What a rare find! "Six planets: a super-Earth and five mini-Neptunes. After monitoring it for seven years, astronomers have discovered that all six of those planets are orbiting HD 158259 in almost perfect orbital resonance."

It took them 7 years to figure out the planets orbit?

88 light years away is very far. It has only been in the last 30-40 years that we have started to have the telescopes and instruments able to start to "see" the planets around stars. Using visual, x-ray telescopes, ultraviolet telescopes and more, scientist are pealing back space bit by bit. There is a new space telescope that will come on line that will be much more powerful than Hubble was. Stay tuned for more big announcements in the next few years.

I thought the concept of gravity was obsolete now and we were to understand the pull as planets going through space curves. If that's true, I think it must be the nature of the curves rather than a symmetry in gravity.

. . . to clarify . . .

The (Newtonian) idea that gravity is a force is obsolete. Einstein convinces us that gravity is a curvature of spacetime.

The "nature of the curves" is caused by the mass(es) of the object(s)

Interesting!

Cool read. I'll leave it up to the scientists.
