Her latest book, "Why Am I Taller?", is co-written with astronaut Dave Williams. Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, working inside a spacesuit, and participating in a simulated Mars mission.

You might want to read Stephen Hawking's most far-out ideas about black holes to see how strange they really are. We've also taken a look at white holes, the opposite of black holes, and how black holes have impacted video games. To learn more about black holes, check out our black holes reference guide and this look at where black holes lead to. More distance in theory could mean better resolution, allowing for even more detailed images of black holes in the future. It works by expanding the available distance between individual radio telescopes to beyond what the Earth's surface could provide. Their concept is called the Event Horizon Imager. In 2019, astronomers at Radboud University in the Netherlands said they, the European Space Agency and others would eventually like to place two to three satellites in orbit around our planet. While the EHT has produced stunning black hole imagery from the ground, the next generation of such work could be produced in space.

"Here, we're fitting for the average image structure, along with an extra source of variability noise that's sitting on top of that average," Johnson said.
The second model sought to fit all the data in at the same time. This was combined into a single, averaged-out model. The first was to divide the data by time and to fit them to snapshots of the black hole in action, to make sure the measurements weren't "contaminated" by variability in its environment. There were two ways they worked with the models.
"It gives us a different perspective, and it lets us understand the systematic biases of both methods because these simple models are easier to constrain with very limited data." "This is a different approach than imaging," Johnson said. They also developed more simplified models "that we can fit directly to the EHT data," Harvard and Smithsonian astrophysicist Michael Johnson told reporters after the black hole's imaging was announced on May 12, 2022. To understand the bizarre physics of the environment of Sgr A*, the imaging team used tools and models to measure the properties that were observed.
