☆ Scientists a step closer to unraveling mystery of sun’s magnetic field
  + stars: | 2024-05-22 | by ( Katie Hunt | ) edition.cnn.com   time to read: +5 min
In contrast to previous research that assumed the sun’s magnetic field originates from deep within the celestial body, they suspect the the source is much closer to the surface. This view of the sun's magnetic field was generated by NASA's Solar Dynamics Observatory. NASA/GSFC/Solar Dynamics ObservaModeling the sun’s magnetic fieldIt’s difficult to see the sun’s magnetic field lines, which loop through the solar atmosphere to form a complicated web of magnetic structures far more complex than Earth’s magnetic field. To better grasp how the sun’s magnetic field works, scientists turn to mathematical models. Like the 11-year solar magnetic cycle, torsional oscillations also experience an 11-year cycle.

☆ Ancient galaxy reveals a surprising way to annihilate a star
  + stars: | 2023-06-22 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +6 min
The explosion lasted just over a minute — considered long, like any gamma-ray burst, or GRB, that lasts more than two seconds. These violent, destructive bursts can leave behind dense remnants like neutron stars or result in the creation of black holes. Why ancient galaxies could hide star deathsDuring their search for the origin of the gamma-ray burst, astronomers used the Gemini South telescope located in Chile to observe the afterglow of the cosmic explosion. Compared with younger, more typical galaxies, ancient galaxies can have up to a million or more stars densely packed into their cores. But they had no evidence for any long gamma-ray bursts originating from ancient galaxies — until now.

☆ Structures newly discovered in the Milky Way
  + stars: | 2023-06-02 | by ( Kristen Rogers | ) edition.cnn.com   time to read: +5 min
CNN —An international team of astrophysicists has discovered hundreds of mysterious structures in the center of the Milky Way galaxy. Sagittarius A* “is the closest supermassive black hole to us, but it’s relatively quiet and therefore somewhat difficult to really study,” Hamden added. The vertical filaments surround the nucleus of the Milky Way, but the horizontal ones appear to spread out to one side toward the black hole. The vertical filaments, on the other hand, are magnetic and hold cosmic ray electrons moving nearly as fast as the speed of light. “One way to confirm that the (filament) structure is created by something like a jet is to find both sides of it.”This would add “to the complex, active picture of our own Milky Way,” she said.

☆ Messy eating habits might reveal elusive black hole
  + stars: | 2023-04-25 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +3 min
The clues uncovered in the experiment might help astronomers find intermediate-mass black holes by searching for evidence of their behaviors. During the simulations, the intermediate-mass black hole snagged the star in its orbit, and each time the star made another lap, the black hole took another bite out of it. Each flare is brighter than the last, creating a signature that might help astronomers find them.”The search for elusive black holesAstrophysicists are still trying to prove if intermediate-mass black holes exist in the first place. The mass of a medium-mass black hole is thought to be between that of a supermassive black hole and a much lower-mass black hole. For example, what appears to be an intermediate-mass black hole might actually be the accumulation of stellar-mass black holes.”During the 3D modeling experiment, stars were able to complete as many as five orbits around an intermediate-mass black hole before being kicked away.
