@venkatessh Awesome!

[Geoff Bower @gbower314]

Get out your eclipse glasses and take a look at that sunspot!

[Geoff Bower @gbower314]

This makes me want to have a martini (or three or ten) with @Shteyngart.

#OTD 5 years ago, the @ehtelescope (EHT) shared the first image ever of a #BlackHole!

The black hole was M87*, and since then, the EHT also imaged Sgr A* (the black hole at the heart of our galaxy) and both objects in polarised light.

Can you say which image matches each? 1/

[Event Horizon 'Scope @ehtelescope]

Breaking news: the Event Horizon Telescope team unveils strong magnetic fields spiraling at the edge of Milky Way’s central black hole, Sagittarius A*. This new image suggests that strong magnetic fields may be common to all black holes.

New EHT image in ApJL: Strong magnetic fields spiral around SgrA*, seen in polarised light for the 1st time. Similarity to M87 suggests strong magnetic fields may be common to all black holes. @someJIVE says new tools were essential for this result: https://t.co/Z94gTmpkwc

@iaavlbi @ehtelescope @iaa_csic On my way!

[Geoff Bower @gbower314]

Exciting new results on M87 from the @ehtelescope!

[JIVE @jivevlbi]

Out now in A&A: new images of M87* from @ehtelescope's 2018 observations reveal the same BH shadow size since 2017—as GTR predicts—and a shift in the bright region's location. Greenland Telescope joined for the first time. More results expected. Full info: https://t.co/wKVhT5aJFf

[Event Horizon 'Scope @ehtelescope]

The EHT has revealed the strong magnetic fields of the M87* black hole in a new light! An analysis of light in circular polarization supports earlier findings that the magnetic field near M87* is strong enough to occasionally stop the black hole from swallowing up nearby matter.

@smith_randallk @eilatg @JustTheLetterU I'd take one, if available

[Event Horizon 'Scope @ehtelescope]

#OnThisDay 4 years ago, we unveiled the very first image of a black hole!

[Geoff Bower @gbower314]

@joey_neilsen Very sorry to hear this, Joey.

[Geoff Bower @gbower314]

@ProfSeraMarkoff I met him once. He came to Berkeley because he was working on a song that would only be played when a SETI signal had been discovered.

[Geoff Bower @gbower314]

@whereisyvette Thanks. I hadn't seen this before.

[Geoff Bower @gbower314]

@whereisyvette Interesting, Yvette. Are you able to flag out starlink channels and make a good image from the rest of the band?

[Geoff Bower @gbower314]

@Astro_Wright @sciam Thanks for this, Jason. Elimination of a proprietary period will be a race towards the bottom.
