Want to Get Away? NASA Now Offers More Than 6,000 Alien Worlds to Daydream About Itโ€™s a crowded galaxy, the latest exoplanet tally shows

Nice @sciam.bsky.social article by @sarahexplains.bsky.social on the NASA Exoplanet Archive reaching 6,000 planets!

โ€œYouโ€™re no longer just asking โ€œwhatโ€; youโ€™re asking โ€œwhyโ€โ€”โ€œand thatโ€™s, for me, where it gets exciting.โ€

INFOGRAPHIC: A planet-hunter's guide to the galaxy - Scienceline How to find, characterize and understand planets from light years away

When I first reported on exoplanets in 2014, there were just 1,000 confirmedโ€”and watching the trajectory since then has been fascinating.

We've reached 6,000 confirmed exoplanets! I talked with @aussiastronomer.bsky.social about where things go from here. (A great graphic by @unamandita.bsky.social visualizes the amazing jumps in planet finds since the first ones were confirmed in the 1990s.)

Teen Hannah Cairo's Mathematical Discovery Sends Ripples through Harmonic Analysis When she was just 17 years old, Hannah Cairo disproved the Mizohata-Takeuchi conjecture, breaking a four-decade-old mathematical assumption

Interstellar Meteors Are Probably Hitting Earth All the Time, Scientists Say Astronomers think small space rocks from beyond our solar system routinely strike Earthโ€”but proving it isnโ€™t easy

Now on @sciam.bsky.social, from @philplait.bsky.social:

The sky is fallingโ€”from another star.

There's no "Chicken Little" nonsense here, thoughโ€”this is legit: Some fraction of the meteors that streak thru Earth's skies are from beyond the solar system!

There are weird circle-y volcanic on Venus called coronae, and now scientists think that they're itty bitty baby circular subduction zones! How cool is that? ๐Ÿงช๐Ÿ”ญ
