Unveiling Our Galaxy's Black Hole
On Thursday, May 12, 2022, the Event Horizon Telescope (EHT) collaboration, including scientists at the CfA, released the first-ever image of the black hole at the center of our Milky Way galaxy.
How is Sgr A* different from M87*, the black hole we first saw in 2019? They differ in size – and this impacted how each black hole was imaged. Learn how the @ehtelescope captures images of these objects that are constantly on the move. #OurBlackHole
M87* and Sgr A*: Comparing Black Holes
How do the black holes M87* and Sgr A* differ in size — and how did this affect imaging each black hole?
A black hole is burping up the remains of a star that it shredded and consumed nearly 3 years ago. “This caught us completely by surprise — no one has ever seen anything like this before," says astronomer Yvette Cendes.

41 light-years away is the small, rocky planet LHS 475 b. At 99% of Earth’s diameter, it’s almost exactly the same size as our home world. This marks the first time researchers have used Webb to confirm an exoplanet. go.nasa.gov/3VY5WK1#AAS241
ALT Graphic titled “Rocky Exoplanet LHS 475 b Transit Light Curve, NIRSpec Bright Object Time-Series Spectroscopy.” Behind the graph is an illustration of the planet and its star. The graph, or spectrum, shows the change in relative brightness of the star-planet system between 3:00 p.m. and 6:00 p.m. in Baltimore, Maryland, on August 31, 2022. The spectrum shows that the brightness of the system remains steady until the planet begins to transit the star. It then decreases, representing when the planet is directly in front of the star. The brightness increases again when the planet is no longer blocking the star, at which point it levels out. The graph shows data in purple circles, which chart measurements before, during, and after the transit. Data form a U-shaped valley of low brightness labeled “Starlight blocked by the planet” at 5 p.m. This dip cuts into a flat plain of high brightness labeled “Starlight,” which starts before the U-shaped dip, and resumes after the dip.
