Astronomers discover Andromeda XXXVI, an ultra-faint dwarf satellite galaxy

By analyzing the data from the Pan-Andromeda Archaeological Survey (PandAS), European astronomers have discovered a new satellite of the Andromeda galaxy. The newfound object, which received the designation Andromeda XXXVI, appears to be an ultra-faint dwarf galaxy. The finding is reported in a paper published March 30 on the arXiv preprint server .

Water on the moon? New study narrows down the mostly likely locations

Water likely accumulated on the moon slowly over billions of years, rather than during one big event, according to a new study by an international team of scientists. The researchers, including Paul Hayne, a planetary scientist at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder, have published their findings […]

Artemis astronauts survey lunar surface on flyby, solar eclipse up next

The four astronauts carrying out NASA’s first lunar flyby in more than half-a-century were sending back detailed observations of the moon after traveling farther from Earth than any human before.

If life exists in Venus’s atmosphere, it could have come from Earth

The theory of panspermia holds that life is spread through the cosmos via asteroids, comets, and other objects. When the building blocks of life emerge on one planet, impacts can eject surface material into space, which then carries these seeds to other worlds. For decades, scientists have debated whether this could have occurred between Earth […]

Water-repelling surfaces reveal surprising charging effects

Materials that repel water are used in countless applications, including industrial separation processes, routine laboratory pipetting, and medical devices. When water touches these surfaces, the interface where they meet tends to acquire a small electrical charge—an effect that is ubiquitous, yet poorly understood. KAUST researchers have now studied this in detail and their findings could […]

Experiments refute dark matter claim

The doctoral thesis of Sophia Hollick, Ph.D. ’25, a recent graduate of Yale’s Wright Lab in professor Reina Maruyama’s group, has significantly contributed to answering a decades-long question in her field about whether or not a signal observed in an experiment that has taken data since 1997 was indicative of a direct detection of dark […]

Mechanical inputs boost diamond quantum sensor states as Q factor tops one million

Most people think of diamonds as high-end adornments. Not Ania Bleszynski Jayich. The UC Santa Barbara physicist sees diamonds, which she grows in the UC Quantum Foundry, as a potentially powerful foundation for quantum sensors. Sensors are currently much farther along in their development than other potential quantum applications. Diamond sensors are particularly promising because […]

Quantum ground state of rotation achieved for the first time in two dimensions

Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research team at the University of Vienna, together with colleagues at TU Wien and Ulm University, has now cooled the rotational motion of a levitated silica nanorotor all the way to its quantum ground state—in […]
