Last yearโ€™s financial experts turned into last monthโ€™s political experts turned into last weekโ€™s crowd management experts turned into yesterdayโ€™s aviation experts. Stay away from these experts. Save your intellect. Save your sanity.

My last stop in Switzerland was at FHNW Astroinformatics+Heliophysics located within the FHNW (University of Applied Sciences and Arts), Brugg-Windisch. I gave a seminar on space weather induced geomagnetic storms and satellite orbital decay and met up with Sam Krucker and his group. Sam is a pioneer

Our computer vision textbook is now available for free online here: visionbook.mit.edu We are working on adding some interactive components like search and (beta) integration with LLMs. Hope this is useful and feel free to submit Github issues to help us improve the text!

Plasmonic catalysis moved from TRL 1 to 8 (SYZYGY Plasmonics). Our BLACK GOLD based catalyst, far superior in activity, selectivity & simplicity. But we stuck at TRL 3. Why? Institution STOPS startups. Who benefits? Not the country-science or scientist. PMO India DAE India

The #monsoon rains have arrived and it feels good to be back home in Kolkata. The grass is familiar here. But I am full of enduring memories of Switzerland, where I was the gypsy scientist...on the tracks connecting one academic institution to another.

Scientists can now observe dynamic temperature changes precisely in the Sun's outer atmosphere thanks to new technology introduced by NASAโ€™s CODEX instrument. This animated, color-coded heat map shows temperature changes over the course of a couple days, where red indicates

This region is exhibiting signs of increasing magnetic complexity, and further M/X-class flares are anticipated. In addition, AR 14110 and AR 14105 are also identified as flare-productive, indicating a sustained risk of flare-induced ionospheric disturbances in the coming days. +

A Coronal Mass Ejection (CME) associated with the M8.4 flare was detected; however, current analysis suggests it is unlikely to be Earth-directed, and thus the chances of geomagnetic impact remain low. +

Several small to medium-sized filament structures are visible on the Earth-facing side of the Sun, which could launch Earth-directed CMEs if they erupt. +

The solar wind speed is currently around 400 km/s. A large coronal hole located in the southern hemisphere of the visible solar disk is expected to contribute to a slight increase in solar wind speed in the coming days due to high-speed solar wind streams.

Proba-3 achieves its first โ€˜artificial total solar eclipseโ€™ in orbit! The mission can create such eclipses once every 19.6-hour orbit & make them last up to 6 hours. Using these observations, scientists will be able to answer long-lasting questions about our home star ๐Ÿ‘‡

We were there to witness the European Space Agency #Proba3 mission take off on a ISRO PSLV rocket from India's famed launch site at Sriharikota on the Bay of Bengal. You see the contrails of the rocket just after launch and today you see the first light eclipse! So happy for team Proba-3.
