Here is a galaxy that seems like a beautiful flower, in honor of June Bride—a galaxy pair, Arp 273, shot by Hubble Space Telescope. Fine features of distortion and tails that inspire us to a rose are thought to be formed in the interaction of two galaxies. (T.K.) #ScenicGalaxy

✨ TMT: Where the Universe Comes into Focus ✨ On May 30th, TMT’s Fengchuan Liu and Dave Andersen hosted a webinar diving deep into the science and engineering behind the Thirty Meter Telescope. They discussed how TMT’s design has been optimized to deliver groundbreaking science

[Q.209] A galaxy quiz of today is related to the current rainy season. This spiral galaxy is distinctive with narrow arms stretched straight from both ends of the disk, and the faint arc-like spreads at the tips of those. What is the nickname of this galaxy? (SS) #GCQA

🎥Orion Nebula Captured by the #SubaruTelescope At the heart of the Orion Nebula (M42) lies the Trapezium Cluster—massive newborn stars whose UV light ionizes surrounding hydrogen gas, creating that iconic red glow. Enjoy the M42 movie: youtube.com/watch?v=yripnw…

Orion Nebula M42, taken with #SubaruTelescope’s Hyper Suprime-Cam (HSC), is included in #GALAXY_CRUISE classification site. The color tone is different from the newly processed image, but it is an advantage that we can zoom and scroll as we like in #GALAXY_CRUISE.

[Q.210] Today, I introduce a galaxy “LEDA 1313424” in the direction of Pisces. This galaxy has a certain nickname based on its appearance. What is the origin of the nickname? (JA) #GCQA

The ALMA Board approved the development of a new spectrometer for the Morita Array designed and developed by Japan. The development will be undertaken by a joint team of researchers and engineers from KASI and NAOJ.alma-telescope.jp/en/news/tpgs-2…

[Q.211] The first images were released from the Rubin Observatory “LSST Camera”, which may be said to be the next generation of Subaru-HSC. HSC has a characteristic wide field of view equivalent to nine full moons. What wide area is LSST capable of observing at once? #GCQA (MA)

(Choose an answer from below.) In terms of the full moon area,
