(To be clear, we also spruced up a bunch of other content and functionality on the overview pages, the first of a series of rolling updates, so do check them out!) Updates are summarized here: exoplanetarchive.ipac.caltech.edu/docs/exonews...

Brown. Dwarfs. Are. Purple. Fixing what really matters (to me) on the NASA #Exoplanet Archive since December 2024. 🤣 🔭

Little kids are quite clever at naming things for which they do not know the word. 3 yo recovering from a 24 hr stomach bug: "Mommy, I want to keep my diaper on. I have melty poop." 🫠💩

So I’m reviewing *post doc applications* and so far I’ve seen multiple applications with 30-80 papers. Astronomy what are you doing.

The culture of "you must first-author publication(s) as an undergrad in order to succeed/get into grad school" is toxic and favors privileged students. It needs to stop. 🔭🧪

Halloween observations this year: kids prefer fruity candy over chocolate by at least 2:1. Also, nobody ever has, or ever will, like Almond Joy. 🎃

Awesome, another paper of mine has reached 100 citations! 📜

Thank you Colorado State University! Congrats on 60 years of the Madison-Macdonald Observatory! 🔭

Happening tomorrow!

The NASA #Exoplanet Archive now has Gaia DR3 IDs! This should hopefully make your work and planning observations easier! exoplanetarchive.ipac.caltech.edu

It has been a while since I just got to "play" with a telescope! 🔭

How do giant planets influence the type of #exoplanets that form in the habitable zone? A thread 1/🧵

Hey, that narrator sounds familiar! Check out our new NASA #Exoplanet Archive homepage overview! 🔭 youtu.be/RHbvnodAX3g

Now I want a statistical survey of astronomers' favorite planets. But at least K2-138 made this article's list. 🤣

Do you even lift?

The Arecibo sky bridge, as seen from the secondary support structure in 2013. Sadly, this bridge no longer exists. 😞

Join me at Colorado State University's Madison-Macdonald Observatory 60th anniversary celebration on October 17th from 3-8:30 pm! 🔭 There will be solar observing, physics demos, and stargazing, and I will be presenting a public lecture about #exoplanets! www.physics.colostate.edu/about/astron...

I'm hiring at Haverford - a 2 year NASA funded postdoc to work on Galaxy Zoo with Roman Space Telescope Data: www.haverford.edu/human-resour... 👩‍🔬🔭

I gave a talk about my paper last month with this as the title slide. Can you tell I recently watched #Murderbot? 🔭 #Exoplanets

You can access parameters for all 6,007 planets on the NASA Exoplanet Archive at exoplanetarchive.ipac.caltech.edu!

Sometimes 2025 just feels like a lot, and you need an excuse to celebrate your fabulous team (and the whole exoplanet community!) reaching a new milestone… Happy 6,000 Confirmed Exoplanets Day, everybody!!!! (You may recognize the narrator of the video at the link! 🫣) www.nasa.gov/universe/exo...

On the way to daycare, my 3 year old saw me bringing my Hot Wheels Mars Rovers to work today. 3 yo: I want to go to Mars... with you. We go on rocket ship to Mars. Me: 🥹

Extra observing time tonight because I got bad weather last month? I'll take it! 🔭

The advertisement for Carnegie EPL's 2026 postdoctoral fellowship is out! aas.org/jobregister/... We are also happy to host external fellowships like NHFP, NSF, and 51 Peg b (the latter is due Oct 3rd, one month away!). Please feel free to reach out if you have questions. (1/2)

Hey #exoplaneteers (and other early career folks) - applications for the 2026 NASA Hubble Fellowship Program are open! www.stsci.edu/stsci-resear...

This has been stuck in my head ever since the WISPIT #exoplanet announcements yesterday. 🫠 youtu.be/j_QLzthSkfM

The press release from @stewardobservatory.bsky.social is online now: news.arizona.edu/news/growing... #exoplanets ☄️🧪🔭

Our now published paper can be found here! iopscience.iop.org/article/10.3... #exoplanets

My first press coverage 🥹 protect.checkpoint.com/v2/r01/___ht...

Quite astonishing that we can be observing right now ~50 km from where this volcano is spewing its guts. This is our last night of August IRTF observations with @sakhee-space.bsky.social! 🌋 🔭

Completely unrelated, yet surprisingly relevant to our Scaling K2 #exoplanet paper series. See all 8 papers on ADS: bit.ly/41VnRGO

I recently did an interview on the origins of life that is 100% alien-spaceship free. You can read about it here: open.substack.com/pub/storiesf... 🧪🔭

Kepler mission: smaller stars have more short-period, small #exoplanets. Theory: the smallest stars won’t have enough disk material to make small planets so there must be a turnover. Kepler+K2: We have found a turnover! Check out our newest Scaling K2 paper: arxiv.org/abs/2508.05734 🧵 1/9 🔭🧪☄️

WELCOME TO THE FAMILY, ALPHA CEN A b!!! First hinted at in Wagner+21, now Chas Beichman, Aniket Sanghi and team have published new JWST images of alpha Cen A showing another hint of this Saturn-sized planet candidate! exoplanetarchive.ipac.caltech.edu/overview/alp...

I timed it perfectly to the second! New paper coming soon to the top of the Sunday evening/Monday morning arXiv post!

My 3 year old has probably spent more time observing than some astronomers I know. 🔭

In case you were curious, or for some reason need to prove this, The Magic School Bus and Billy Nye the Science Guy were funded by the U.S. Department of Energy. They were also funded by the National Science Foundation, but that was shown in the credits. 🧪

Everybody studying #exoplanets needs to be aware of this incredibly important point! 🔭

If you're unsure about masking on planes, the medication I'm on for Graves' disease can decrease white blood cell count and ability to fight infection. My seat-mate sat down, also masked, and said she was getting over a virus (and has coughed a lot). You help people you don't even know by masking!

My website (kevinkhu.com) is back up and running after a brief hiatus (okay, it's been down since I moved, but I've been busy)!

The law of super glue: no matter how hard you try to avoid it, you will always get it on your fingers.

In case you needed some good news this week: We now have OVER A THOUSAND spectra of PLANETS AROUND OTHER STARS. This is our training ground for modeling extreme weather. For understanding the diversity of planets across our Galaxy. For searching for biosignatures. This is very, very cool.
