50 years ago, U.S. Air Force satellites spotted mysterious flashes of X-rays and gamma rays. Scientists determined that they occurred outside our solar system and published the first paper about gamma-ray bursts! How have we studied them in decades since then? 🧵1/10
A process called magnetic reconnection may fuel some of the most rapid and powerful phenomena in the universe. Two recent papers detail the microphysics that may power these cosmic tantrums. @savagitsky reports: https://t.co/9dQrIxmH8l
Friday Feature: Working with NSE's Professor Jack Hare, PhD student Rishabh Datta seeks to further understanding of astrophysical phenomena.

(2/2) This provides an effective easy-to-implement system for diagnosing plasmas, especially in systems with limited diagnostic access, or where other techniques such as Thompson scattering are unavailable.
(1/2) Our RSI paper which describes a new plasma diagnostic technique for velocity and ion sound speed measurements is now available here:

New preprint lead by @ri_datta studying the structure of bow shocks which form around inductive magnetic field probes. Some really detailed comparison of MHD sims with experiments here https://t.co/8lmXEb5OkI
Congratulations to the MechE Class of 2022! We are excited for you take the skills that you’ve have gained during your time at MechE to help make our world a better place.
Scientists estimate there are tens of millions of black holes dotted around our galaxy, but so far we’ve only found a few dozen. Most of those are in orbit with a star, and this video shows 22 systems studied by our missions! More: https://t.co/DI1rVcXTFB #BlackHoleWeek⚫
Investigating the interactions between geomagnetic storms and magnetospheric substorms is one of the most challenging problems in space physics and has crucial impact on any forecasting tool. Find out more: https://t.co/PSbAqzXtGb
In a world first, the National Ignition Facility has generated a “burning plasma,” a fusion reaction on the cusp of being self-sustaining. https://t.co/0TmUPsvlUK
Princeton doing the right thing and removing graduate "tuition" so they can pay PhD students more. Why should a PI mentor pay the school tuition for their student in yr 3+ w/ no classes? What is that money for? Should be research funds!
For years, we’ve been answering the question: When will #NASAWebb launch? This morning, we answered that for the last time! Next up: Where is Webb? We’ve got an answer for that, too!
See where Webb is on its million mile journey to #UnfoldTheUniverse: https://t.co/EZC60K56YN
Happy Black Hole Friday! This simulated black hole movie shows what scientists think an accreting supermassive black hole system would look like up close. Retweet at 100% discount this Black Hole Friday!
