The Solar System Exists Inside a Giant, Mysterious Void, And We Finally Know Why

 <https://www.sciencealert.com/michelle-starr> MICHELLE STARR

12 JANUARY 2022

The Solar System floats in the middle of a peculiarly empty region of space.

This region of low-density, high-temperature plasma, about 1,000 light-years across, is surrounded by a shell of cooler, denser neutral gas and dust. It's called the Local Bubble, and precisely how and why it came to exist, with the Solar System floating in the middle, has been a challenge to explain.

A team of astronomers led by the Harvard & Smithsonian Center for Astrophysics (CfA) has now mapped the Local Bubble with the highest precision yet – and found that the Local Bubble was likely carved out of the interstellar medium by a series of supernova explosions millions of years ago.

If this email wasn't addressed to you and you would like to join the group, or if you have a friend or colleague who might also be interested in joining, it's easy.  Ask them to go to the group's wiki page at  <http://LCTG.toku.us> http://LCTG.toku.us and follow the simple instructions under "Join the Email List".  By being a member of the group you'll get reminders of upcoming meetings and infrequent related messages. No advertising.  The list is tightly managed.

Membership is free and given that all meetings are using Zoom you only need to be connected to the Internet to join. It's ok to join from anywhere you can get a decent Internet connection.

We, the Lexington Computer and Technology Group, will meet Wednesday at the usual 10AM Eastern Time, BUT ONLINE, using the Zoom Video Conferencing Application, facilitated by Steve Isenberg. 

There is an instruction page at https://toku.us/zoomish but note that the URL and phone number shown are examples.

 

To join our meeting, sometime after 9:45 AM on Wednesday, choose one of the following options:

*	If you have the Zoom application installed, start it and join meeting with ID 972 6146 0830
*	From your browser, go to: https://zoom.us/j/97261460830
*	From your smartphone, tap this: +16468769923,,97261460830
*	From a “dumb” telephone, call 1 646 876 9923 and enter meeting ID: 972 6146 0830 

Once the connection is established, you may need to locate and use the on-screen controls that turn on the sound and the video. You should be able to see and hear others and they should be able to see and hear you, if you have a camera and microphone (each of which you can unmute selectively).
