Around 800 trees in the ground for today's Trees for Canterbury planting day! A big group of students from UC there helping reclaim another part of Ōtautahi for nature.

Nice to see Kepler/K2 and TESS leaving their marks on MAST!

Think of what we have learned and have yet to learn from investing in these missions and making their data open and available to everyone.

700 new native trees in the ground from today's Trees for Canterbury planting at Orton Bradley Park. Another small patch of Aotearoa returning to what it was.

It's always nice to check in on my thesis when visiting Mt Stromlo 🔥

Fantastic presentation on Timescape by @ryanridden.bsky.social yesterday at the South Island Stardate. Exciting times in cosmology! He also gave an awesome presentation on Cosmic Cataclysms and how we can get involved in it through zooniverse. Wow! Some great research going on at UC!

New paper up on arXiv! We present the TESSELLATE pipeline to conduct a general transient search of all TESS data. This is a massive goal that I've been working towards for years which was made possible by my incredible students and co-authors!

We have more data going up now! Keep an eye out for a comet that is photobombing TESS ☄️

I'm amazed at how fast the citizen scientists tore through the dataset. It's made something that seemed like a insurmountable task suddenly feel very achievable!
Over 26000 classification in less than a day blasting through out initial dataset!
Thank you everyone for your help, but don't worry there will be more data to search and discover new Cosmic Cataclysms very soon!

Just a few hours in and a lot of cool discoveries already!
Here's a newly observed outburst from the cataclysmic variable ASASSN -14je.

A nice spot for writing a paper on exploring the dynamic universe.

Our beta test has just been running a few hours and we're already halfway through the test set!
