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.

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

In analysing just a few sectors we already have an extraordinary number of objects to study across all areas of astronomy! If you like grb afterglows, stellar flares, dwarf novae, variable stars, asteroids, and even exoplanets, then we've got lightcurves for you!

A series of TESS lightcurves extracted by TESSELLATE which include example events of GRB afterglow, dwarf nova, flare star, variable star, asteroid detections, and an exoplanet candidate.

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

Never thought I would hold a piece of Hubble. Today was a good day.
