Off-center stellar death points to wandering supermassive black hole stripped of its own g

Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at the center of a visible galaxy. The paper outlining this re

Shining blue light on gold-graphene nanodots achieves wound healing trifecta

Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, one to clean the wound and one to support recovery.

Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole

A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" was simply doing something ordinary that many stars do

Giant exoplanet may hold a magnetic grip on its host star

Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.

Decline in plankton across Northeast Atlantic sends stark warning for ocean health

Microscopic plankton are among the most important organisms on Earth. Phytoplankton produce around half of the oxygen we breathe, while plankton as a whole underpin marine food webs, support fisheries, help regulate carbon and sustain life across the ocean.

A good idea is not enough: Experts explain what helps digital health start-ups succeed

A new study by researchers at Kaunas University of Technology (KTU) in Lithuania has shown that a good idea alone is not enough for health startups to succeed. What matters most is access to data, health care institutions and funding.

Nearby 'Super Earth' may be a better candidate for life than previously thought

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years

A cataclysmic collision in space provides new clues on astronomy's biggest stalemate

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

Webb reveals merger scars in galaxies that stopped forming stars 9 billion years ago

Research has shed new light on why some distant galaxies suddenly stop forming stars. An international team led by astronomers at the University of Nottingham has used the James Webb Space Telescope to study a large sample of recently "quenched" galaxies in the distant universe,
