Mars atmosphere shedding charged particles onto Phobos?

New research suggests that particles escaping from Mars’ atmosphere have been accumulating on the surface of the planet’s largest moon Phobos for billions of years. They could provide important new details about the history of both worlds. Source: https://earthsky.org/space/mars-atmosphere-history-phobos-soil…

Astronomers offer possible explanation for elusive dark-matter-free galaxies

A team led by astronomers at the University of California, Riverside, has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the past.

Exchange bias set in a spin-glass phase could arise in a disordered antiferromagnet

A team of researchers from the University of California, Lawrence Berkeley National Laboratory, the Nuclear Research Center—Negev and the National High Magnetic Field Laboratory has developed a way to isolate antiferromagnet (AFM) heterostructures in the absence of a ferromagnet (FM) to study the coupling that occurs between AFM order parameters and spin-glass parameters. In their paper published in the journal Nature…

More Companies Are Joining ‘Tech Exodus’ From California

This week Digital Reality data center services announced it was also relocating its headquarters from the San Francisco Bay Area to Texas, citing factors like a low cost of living and “supportive business climate”. (Though it will still maintain a “significant” presence in the Bay Area.) And Align Technology (makers of the Invisalign orthodontic dental aligners) also announced it had relocated…

New and rare direct image of a brown dwarf

Astronomers have obtained one of the best images yet of a brown dwarf, an object in a mass range midway between stars and planets. This brown dwarf – called HD 33632 Ab – lies 86 light-years from our sun. Source: https://earthsky.org/space/new-brown-dwarf-direct-image-hd-33632-ab…

Dark storm on Neptune changes direction, escapes deadly fate

Astronomers used the Hubble Space Telescope to observe unusual weather on the planet Neptune, not observed until now. They saw a large, dark storm on Neptune unexpectedly changing direction, thereby saving itself from looming destruction and possibly producing a smaller companion storm.
