Hello new followers! I'm Shishir, and I study all things exoplanets. Below is an artist's rendition of Gliese 12 b, a planet I co-led the discovery of this year. I plan to post more cool things I come across in my research. I also love astrophotography, so stay tuned for pretty space pictures! 🪐🔭

Red planet at the right of the frame illuminated by a reddish host star, with a distant starfield in the background.

Jupiter rotation timelapse with lo (and shadow) transit! Taken Feb 8th from my backyard. Went out at 5 min intervals to capture a video. From each of these, the best 10% were stacked to produce a single frame (lucky imaging).

Do you like binary stars? How about Wolf-Rayet stars? May I introduce you to my new chapter on what happens when you put WR stars in binaries... awesome colliding wind binaries!

Just got back from a trip to Arches National Park. Got a lot of shots that I'm excited to process soon! 🌌🔭

A photo of a reddish landscape with a starry sky and the Milky Way stretching vertically near the center of the sky. In the foreground are several pools of water reflecting the starry sky.

Deeply sad to hear of Prof. Fajan's passing--a deeply inspiring and dedicated educator at Berkeley.

When I took his instrumentation class, COVID switched us to remote mid-semester. He ended up hand soldering Arduino kits and mailing them to us for the final project.

Devastated to learn that Joel Fajans has recently passed away - one of the most inspiring lecturers I ever had as a student. He was so creative and engaging. I think about his lecture on the physics of bikes every week!

C/2023 A3 (Tsuchinshan–ATLAS) and the Moon rising over Brisbane. I took this timelapse on 30th September while it was still in the early morning sky, with @astroryan.bsky.social. Reposting on bluesky for all the new people here!

That curve is caused by projection of the sky onto a flat sensor -- it can be created in a single shot by a fisheye lens. The wide-angle lens I used for this shot is rectilinear, so the Milky Way appears as a line.
