Mutuals from twitter times will remember my very dark yrs of Long Covid 😵‍💫 I lost so much, but found a wonderful silver lining to the dark cloud: I decided to use all the time in bed to v slowly write a book. It took 3yrs. I can't quite believe that tomorrow is publication day & Fri is book launch! 🥹

Almost 1st thing done in Live Astronomy during @dragoncon.org last Friday night - from SARA 1m Kapteyn telescope at La Palma, series of 30s exposures of Nancy Grace Roman space telescope transiting the faint galaxy KOS 222659.3-215011 in Aquarius. (Range 636,000 km)

A murmuration of starlings above Sardinia, Italy. One of my favorite natural phenomena.

Love this from @sabs.bsky.social (and you can bet I clicked so fast to make sure I wasn't in here 😅) you simply cannot write a triumphant headline every time Musk announces a new Mars timeline

Sabrina Imbler@sabs.bsky.social · 4w ago

inspired by @davelevitan.bsky.social and @astrokatie.com, I looked back at how the mid-aughts headlines promising Mars colonization by 2020-something have aged over the years, and what lessons we might take from this defector.com/lets-remembe...

This is a huge honking deal. The Nancy Grace Roman Space Telescope will launch tomorrow. (Knock on wood.) It will have a field of view of the universe that is one hundred times the width of what the Hubble Space Telescope sees.

NASA's newest telescope launches to space tomorrow morning. Lots of science, behind-the-scenes prep, and, of course, space feels, here: www.nationalgeographic.com/science/arti...

thank you the new yorker and françoise for having me do this cover for the late, great dolly parton

Kennedy Space Center is like a who’s who of US astronomy today

And if you’re all, “why anOTHER space telescope there are so many already,” @popsci.com and I have you covered 🧪🔭

I'm so pleased to have made my debut in @sciencenews.bsky.social with this story about (a taste of) all the cool science NASA's Nancy Grace Roman Space Telescope--launching Sunday!--is due to tackle 🧪 🔭

NASA’s new space telescope will reveal the universe like never before

NASA’s new Nancy Grace Roman space telescope will tackle nearly every aspect of astrophysics, including dark matter, dark energy and alien planets.

NEW: Initially, the glacial collapse in Nepal was thought to have been triggered by an earthquake. It turns out that the magnitude 5.2 quake *was* the explosive force of the landslide itself—involving 400 million tonnes of rock and ice. Me + others @nytimes.com www.nytimes.com/2026/08/27/w...

The Nancy Grace Roman Telescope, scheduled to launch on Sunday, will explore the universe's most enigmatic mysteries, like dark matter and dark energy, and find many new exoplanets. This summer, I spent the day with Roman in a NASA clean room, for Nat Geo: www.nationalgeographic.com/science/arti...

despite the unfortunate happenstance, I was very honored to have been quoted in this article by @marinakoren.bsky.social ! Swift will be dearly missed 🔭☄️🧪

The Swift Observatory is slowly falling toward Earth’s atmosphere. A rescue mission was sent to save the space telescope, but it tumbled out of control. There is no backup mission to save Swift. https://www.sciencenews.org/article/swift-space-telescope-failed-rescue

A space telescope was falling from orbit. Its rescue mission fell apart too

NASA’s attempt to save the falling Swift telescope failed, revealing the realities of the burgeoning field of satellite servicing.

This is a reasonable and pragmatic attitude that will never fly on the internet… But seriously, the important features of Pluto *for me* are that it is a differentiated body with a recognisable geological history. *For me*, that also says “planet”, if other people want to use different boxes, 🤷‍♂️

Even if your area will not have a Total Solar Eclipse (which is worth making an effort for if you are close by!) a partial eclipse is interesting, too. Do NOT look at the Sun! (Unless using eclipse glasses!) It is fun to see the patterns the partially eclipsed Sun makes on the ground under trees.
