For anyone disappointed by 2024 YR4's disappearing threat please remember that even at its peak of ~3% chance it still had a negative rating on the Palermo scale. 1/

📢 Te Matatini - the national kapa haka championships - kick off in New Plymouth tomorrow, the first time the event has been held in Taranaki for more than 30 years.

Meanwhile, it's my turn on Asteroid Patrol this morning, so I'm posting in one window while controlling the IRTF from 3 other windows, all while sitting in my bathrobe and eating @jagrier.bsky.social's experimental waffles. Currently we're looking at 2021 PS2 to determine what it's made of. 🔭 1/

Looking forward to seeing how this simulation reconciles with our he awa whiria tidal streams of interstellar objects, which start a bit further out 🔭

We're currently advertising for our second UC Ursula Bethell Writer in Residence for 2025, co-funded by Creative NZ. 6 months, late July 25 - late Jan 26, $82Kpa pro-rated, a nice office up with me with some of the best views in the city. Happy to answer qs. jobs.canterbury.ac.nz/jobdetails/a...

#2024YR4 New observations will continue.

Via #NASA - New observations of #2024YR4 have enabled planetary defense experts to refine the asteroid's chance of impact in 2032. As nightly observations continue, the impact probability will continue to be updated. New data reduced the impact probability to 1.5%. blogs.nasa.gov/planetarydef...

First grad student in our group defends today and I am Proud Advisor

Just in case you thought DEI was some new-fangled idea at NASA, I found this Equal Opportunity Award trophy at NASA HQ today which was first awarded to Goddard Space Flight Center in ***1980***, which was 45 years ago for people who are too afraid to count.

Very glad that the Australian government has announced they will extend funding of the Anglo-Australian Telescope until at least 2027. So many surveys depend on this facility - which for so long has been a vehicle for bringing wonderful astronomers to Australia to use it and growing our community.

Here's the story with more information on NASA's reprieve from cutting more than 1,000 employees today.

“There is no route from our current state of the research system... to any part of the new state of the research system.”

The best dark sky in the world - the Atacama Desert in Chile, which hosts many @eso.org telescopes - is under threat from an industrial project. 🔭 Astronomers can sign a petition in favour of moving the planned industrial project: docs.google.com/forms/d/e/1F...

It is very good to think about interstellar objects for an entire morning even if I still need a nap after thinking for slightly too long

A new round of the Lise Meitner Excellence Program for #tenuretrack group leaders opened today - please consider applying! The program aims to recruit and promote exceptionally qualified female scientists. www.mpg.de/lise-meitner... #LiseMeitnerGroups #WomeninScience #ScienceCareer

Up in my veggie garden there’s an old seat settled amongst a profusion of wild mombretia irises and a jumble of summer flowers. Intentionally chaotic, it’s my favourite thinking place. #AotearoaGardens 🇳🇿🌱

If you follow the accounts of planetary scientists here, you may have heard about the suspension of the Here to Observe program. I'd like to take a few minutes of story time to tell you about it, if you're interested. (1/n)

Non-specialists may ask "how is it no impact threat but also potentially hazardous?" This is an unfortunately named definition--anything > 140 meters that could come within 7.5 million km of earth is just called a "potentially hazardous asteroid", even if we know it can't hit the Earth. (1/2) 🔭🧪

Well, that makes five years as faculty

The day before the start of classes. I do like the annual tradition of handing out bags of mini donuts to everyone on the way in

Sweet pea doing well this year

Well, so much for giving a talk in two weeks; postponed. The turmoil in the US sure has some strange ripples

PAPER SUBMITTED this was a big piece of work and it is led by two students in our group. Very happy it gets to go out into the world

Tidal tails are beautiful examples of what happens when you let gravity play with sparkling sand that isn’t held together by anything more than gravity.

Walking in to NASA’s JPL today as a woman in science leadership felt almost like a protest. They can take us off the webpages and the walls, but we will still be here, absolutely crushing it, and supporting our community while we do it. Happy International Day of Women in Science, everyone.

It's a good feeling to work with solid people who care about creating a robust process with respect and thoughtfulness

NASA senior review reports from 2022 (the PDFs linked on this page) have been scrubbed from NASA websites. I am grateful to archive.org who retains these and other important reports for our field. 🔭🧪⚛️ science.nasa.gov/astrophysics...

New paper, by Leicester PhD student @simintong.bsky.social. Simin presents a new set of models which show that compact protoplanetary discs are a natural consequence of so-called ``dead zones'': regions where disc turbulence is low. 🔭 arxiv.org/abs/2502.04452

Here is the infamous near-Earth asteroid 2024 YR4 from Gemini S acquired with a joint proposal from Catalina Sky Survey (Dr. Wierzchos) and Bryce Bolin. It's currently very faint and approaching magnitude 24. Really pops out with the 8m glass. 🔭🧪

Garden friend 🌱🇳🇿

Put some cherry tomatoes in the back behind the roses, where there was room on the wall. Tomatoes went a bit feral. #garden folks: do I try and thin them out? Lots of flowers but not as much fruit yet 🇳🇿🌱

Taranaki gardeners say growing a tonne-and-a-half of potatoes for Te Matatini was inspired by their forebears feeding war refugees who flocked to Parihaka 150 years ago.
