Welcome news, called it months ago on my piece for the @Openthemag@twitter.com!
https://openthemagazine.com/feature/the-anatomy-of-chandrayaan-2/

Though radio silence on the #Chandrayaan2 landing failure remains a bummer. Not releasing images or a description of #VikramLander after claims of finding it is total disappointment.

there’s only ONE MONTH left in the decade. what have you accomplished?

RT @thewire_in@twitter.com

Do you care about science? We do.

That's why we're bringing out a brand new website devoted to the best science reportage in the country.

But we need your help.

We want to raise 30 lakhs in 30 days.

Can you pitch in?

#Voyager1 and #Voyager2 results brief from entry into interstellar space (IS).
V1
a. Saw galactic magnetic field pockets in the solar bubble!
b. Saw a 10 AU wide plasma transition region in IS.
V2
c. Saw a magnetic barrier before IS.
d. Saw charged particles leaking out to IS.

Alright #space peeps, here's Voyager Interstellar 101, with pretty graphs from the research papers and comparison of results between both @NASAVoyager@twitter.com spacecraft.

Here we go! (1/n)

Here's my detailed article for @thewire_in@twitter.com @TheWireScience@twitter.com on the #Voyager1 and #Voyager2 results with simple explanations.

(13/13)

Perhaps when a future species of ours visit the nearest star, they'll remember @NASAVoyager@twitter.com for laying out a foundation for mapping and characterizing the heliopause and beyond, to enable safe interstellar voyages.
(12/n)

The @NASAVoyager@twitter.com crafts have given us our first glimpse of what the outermost solar structure and the interstellar neigbhorhood is like. 42 years after their launch, the Voyagers just keep on giving! The world has acquired an entire generation of scientists in this time.
(11/n)

Armed with @NASAVoyager@twitter.com data, scientists now know that the heliopause changes in shape and size at different times and places, as the solar and galactic magnetic fields dance around each other.
(10/n)

Before the heliopause, #Voyager2 saw spikes in the plasma density and temperatures. This spanned the Sun-Mars distance. #Voyager1, however, saw no such spikes and only noted a gradual decline.
(9/n)

#Voyager1 saw a transition region between the heliopause (dotted vertical line) and interstellar space, which had increased plasma density. And spanned a distance as large as that between the Sun and Saturn, confirming a 25 year old prediction!
(8/n)

More strikingly, before #Voyager1 crossed the heliopause (HP in the graph), it saw two ‘pocket’ regions (humps in the graph) in the Sun’s bubble where the galactic magnetic field had moved in, bringing energetic cosmic radiation with it. #Voyager2 saw no such thing.
(7/n)

But for #Voyager2, the change wasn't abrupt. Many solar charged particles were found to be leaking out of the heliopause to interstellar space for about about half the Sun-Earth distance, puzzling scientists.
(6/n)

Both #Voyager1 and #Voyager2 saw a drop in amount of charged particles from the Sun as they entered interstellar space and likewise an increase in galactic cosmic radiation.
(5/n)

On to the intriguing results from the interstellar passage.
#Voyager1 found the galactic magnetic field to be weaker than #Voyager2. But Voyager 2 observed something before the heliopause that 1 didn't - A strong "magnetic barrier" spanning the Sun-Venus distance!
(4/n)

#Voyager1 crossed the heliopause in Aug 2012 to enter interstellar space. #Voyager2 did the same in Nov 2018. They are the only spacecraft to have entered the space between the stars and are STILL communicating, 42 years after launch!
