Tabby Star with Tabby Herself this week on planetary radio.

Welcome, I'm A Kaplan of the Planetary Society with more of the human adventure across our

solar system and beyond. Astronomer and astrophysicist Tabitha Boyagian

is here to talk about the star that has generated so much speculation

in the last couple of years. She'll tell us that the evidence for alien

megastructures has not shown up but the science she is uncovering is still extraordinary.

Bruce Betts and I have not won but two new contests to tell you about in this week's

what's up, even as we prepare for the next total

eclipse. First though we journey back to Mars with our favorite tour guide

Planetary Society senior editor Emily Loch Duwala Emily, another great and comprehensive update on curiosity

as it slowly crawls toward the release of your new book as well,

which I always I don't like to miss a chance to plug that that's coming up in March.

But let's talk about the latest from the rover including its progress on the Red Planet.

Yeah, so it's been almost four months since my last update. I was having trouble finding a good stopping point, but curiosity got to a really interesting place.

So in the last four months, the rover has been crawling sort of

southish perpendicular to Vera Rubin Ridge,

which used to be known as Hematite Ridge,

because from orbit, the chrism instrument

on Mars reconnaissance orbiters saw signatures of the mineral

hematite, which is an iron oxide that generally forms in liquid water.

So they've been eager to get to this ridge for a long time.

The ridge does have very pretty looking rocks.
