Year in Science: Revisit a black hole and other seldom-seen sights – GeekWire

Year in Science: Revisit a black hole and other seldom-seen sights – GeekWire

What will people remember about the year 2019 in the year 3019? Just as they're likely to recall 1969 as the year humans first walked on the moon , they might well hold up the first portrait of a black hole as this year's most memorable achievement.

By that measure, there's little question that the Event Horizon Telescope's radio view of M87's supermassive black hole , 55 million light-years from Earth, ranks as the year's top science story. "These are just singular moments in history," White House science adviser Kelvin Droegemeier told me in April when the image was unveiled in Washington, D.C. "We as humans need this."

This may worth something:

Photos of Black Holes Will Blow Our Minds Again in 2020

(Bloomberg Opinion) -- The seemingly impossible, paradoxical news that astronomers had taken a picture of a supermassive black hole captured our imaginations in 2019 for good reason. What they actually showed us was a sort of shadow — a spherical blackness surrounded by a cosmic hurricane of matter and energy — but that was enough to qualify as a sign of real human progress.

Getting that now-iconic image relied on technology that did not exist at the turn of the millennium. The leaders of the project said they counted on Moore's Law to bring the electronic advances they needed. The image was constructed from radio waves picked up at eight far-flung telescopes — from France to Hawaii to the South Pole.

NASA shock: Hubble telescope reveals a behemoth black hole spewing radiation into space | Science

In this case, Hubble’s astronomers estimate a supermassive black hole hundreds of thousands to millions of times heavier than our Sun rests at ESO 021-G004's heart.

Supermassive black holes are the biggest known type of black hole and together with stellar-mass black holes are the most common type seen in the cosmos.

And thanks to the galaxy’s black hole, astronomers consider ESO 021-G004 to have an active nucleus.

Galaxy hunter: Finding a 'monster' black hole - CGTN

"But LAMOST has 4,000 eyes. It greatly improves the observation efficiency and increases our sample size, so the chances of discovering black holes have been greatly increased," Bai said. 

With the advanced features of an instrument like LAMOST, the painstaking job of looking up at the same area of night sky with its patch of the same stars, at the same time, every single day is made a bit easier. And one little abnormal move is enough to get the astronomer's attention.
