Editor’s Note: A version of this story appeared in CNN’s Wonder Theory science newsletter. CNN —The universe is filled with infinite mysteries, and scientists are tackling them, one celestial puzzle at a time. Across the universeAn artist's illustration depicts the Milky Way seen through a neutrino lens, which is shown in blue. National Science FoundationThere is no shortage of scintillating imagery of the Milky Way galaxy — but we’ve never seen it from this perspective. Astronomers used a detector sunk deep into the thick ice of Antarctica to trace “ghost particles” that created a new portrait of the Milky Way.

☆ With neutrinos, scientists observe our galaxy in a whole new way

[1/2] An artist's composition of the Milky Way seen with a neutrino lens (blue) is shown in this undated handout image. Scientists said on Thursday they have produced an image of the Milky Way not based on electromagnetic radiation - light - but on ghostly subatomic particles called neutrinos. Neutrinos are produced by the same sources as cosmic rays, the highest-energy particles ever observed, but differ in a key respect. They released an illustration of their findings with neutrinos from the Milky Way represented by light, with a heavy concentration at the galaxy's core. "The most likely source of neutrinos and cosmic rays in our galaxy," Taboada added, "are the remains of past supernova explosions.

☆ ‘Galactic Panorama’ of Milky Way Details 3.3 Billion Celestial Objects

Astronomers have identified 3.32 billion celestial objects in the Milky Way in unprecedented detail. The galactic panorama of stars, gas, dust and a supermassive black hole known as Sagittarius A* was captured by the U.S. National Science Foundation’s Dark Energy Camera on a 4-meter telescope. It’s housed at the Cerro Tololo Inter-American Observatory in northern Chile, which sits at an altitude of 7,200 feet, allowing for one of the clearest views of the night sky.

A Covid outbreak at an American scientific research station in Antarctica has forced U.S. officials to temporarily halt all travel to the remote outpost. The agency confirmed that 10% of the research station’s population have tested positive for Covid during this recent outbreak. There are 885 people currently living and working at McMurdo Station. Though the station operates year-round, many scientists typically travel to McMurdo in November for field research during Antarctica’s summer season. It’s not yet clear what, if any, impact the outbreak could have on research and operations at the outpost.
