Science: Starfish arms, fighting cells, Black Hole wind

Science commentator Laurie Winkless joins Kathryn with three new studies, including one into how starfish arms can guide and focus light. A team of researchers in Cambridge have looked at how cells can quickly respond to pathogens in the body by forming a membrane around it and sending it to the cell's "recycling bin" and astrophysicists have, for the first time, observed some wind created by a black hole, following five years of compiling and a…

Astronomers find evidence of a wind from Milky Way's black hole

Suddenly, the Milky Way's central black hole is starting to look a little less like a weirdo. Astronomers have discovered a large cone-shaped void in gas surrounding Sagittarius A*, the galaxy's supermassive black hole, that could solve a longstanding mystery. All active black holes should blow winds or jets of material back into space while they're feeding, according to theory. That process is how supermassive black holes shape the galaxies aro…

100 hours of radio observations crack a 50-year black hole mystery

A cone-shaped path away from Sagitarrius A* sights evidence to winds blowing from the black holes.

Milky Way's Missing Black Hole Wind Discovered by Astronomers: Key Findings Revealed

After five decades of extensive research, astronomers have discovered compelling evidence that Sagittarius A*, the supermassive black hole with 4.3 million solar masses at the heart of the Milky Way galaxy, is emitting hot cosmic winds. These winds are shaping a vast cavity close to the galaxy’s center. This image illustrates the winds emanating from [...] The post Milky Way’s Missing Black Hole Wind Discovered by Astronomers: Key Findings Revea…

For more than half a century, theorists insisted that the Milky Way's central black hole had to be exhaling a wind, but the galactic center stubbornly hid the evidence — until a Northwestern team trained ALMA on Sagittarius A* and found a 45-degree cone of missing molecular gas pointing straight back at it

After half a century of waiting, astronomers have caught the Milky Way’s central black hole exhaling. A team led by Northwestern astrophysicists Mark D. Gorski and Lena Murchikova reports evidence of a wind blowing from Sagittarius A* — the four-million-solar-mass object at the galactic center — through a cone-shaped cavity carved into the cold gas surrounding it, a void that can only be explained by hot material streaming outward from the black…

Discovery Of An Active Wind From The Milky Way’s Central Black Hole

One of the fun aspects of astrophysics is that much of it involves phenomena which you cannot exactly study from up close, with the supermassive black hole (SMBH) at the center of this galaxy ̵…
