A team of scientists has discovered a hungry black hole swallowing a star at the centre of a nearby galaxy. The discovery confirms their theories about the nature of black holes and reveals faint jets of material shooting out from the supermassive black hole.
A recent study published in Monthly Notices of the Royal Astronomical Society found that trained volunteers can identify jets shooting from massive black holes and match them to their host galaxies with high accuracy. The project, Radio Galaxy Zoo, uses online tutorials to teach volunteers how to spot black holes and other objects emit...

Researchers found that galaxies in the Coma Cluster could have as much as 100 times more dark matter than visible matter, allowing them to survive and thrive. The study used computer simulations to model how these 'dead' galaxies evolved into their current state.
A study of over 20,000 merging galaxies found that when two galaxies collide, the larger one can stop the smaller one from forming new stars. However, when two galaxies of similar mass collide, they both increase their stellar birth rate.
A team of astronomers discovered a spiral galaxy devouring a nearby compact dwarf galaxy and found remnants of previous galactic snacks. The study used ground and space-based telescopes to measure chemical enrichment in the gas across the entire face of NGC 1512.
A study suggests some galaxies may shoot out gas early, causing them to redden and die prematurely. Researchers found that four galaxies approaching the end of star formation had expelled most of their gas.
Researchers have used radio telescopes in Australia and Chile to observe the remnant of Supernova 1987A, providing insights into the explosion's aftermath. The team has also developed a three-dimensional simulation that reproduces observed features, including the persistent one-sidedness in radio images.
Astronomers discovered a black hole named P13 that is consuming gas from a nearby star 10 times faster than previously thought possible. The black hole is ingesting a weight equivalent to 100 billion billion hot dogs every minute.
Research by Australian scientists reveals massive galaxies are eating smaller ones to gain weight, but their star-formation process is inefficient. Dr. Aaron Robotham explains that gravity allows larger galaxies to pull in smaller neighbors, and the Milky Way will follow suit, eventually merging with Andromeda.
Astronomers have discovered that ALESS65 galaxy is running out of gas at an alarming rate, with only tens of millions of years left, much faster than the Milky Way's 5 billion years. The team found similar characteristics to nearby 'starbursting' galaxies in terms of UV radiation, suggesting a unique star formation process.
Researchers used the interstellar medium as a lens to magnify and observe radio wave emission from a small rotating neutron star, achieving highest resolution ever measured. This technique allowed them to study pulsars, which emit pulsed radio waves, and potentially unlock new insights into their physics.
Researchers measured circular polarisation in the bright flash of light from a dying star collapsing to a black hole, giving insight into an event that occurred 11 billion years ago. This discovery challenges current understanding of Gamma-ray Bursts and suggests a more complex mechanism for their formation.
Researchers found delicate strings of galaxies in previously thought-empty voids, revealing a new type of structure called 'tendrils'. This discovery suggests that voids might be smaller than initially believed, challenging our understanding of the universe's organization.
Astronomers have found a new superpowered small black hole named MQ1 in galaxy M83, which is classed as a microquasar with jets that heat and sweep away surrounding gas. The discovery sheds light on early universe evolution and provides insight into the growth of quasars.
A team of astronomers discovered that black hole jets contain ordinary atoms, including nickel and iron, which provide the positive charge. The jets are accelerated to high speeds, with some moving at 66% of the speed of light, revealing new insights into their formation.
Researchers used gravitational wave data to test models of supermassive black hole growth, ruling out one model and leaving three others as possibilities. The study provides new insights into the growth of massive black holes, shedding light on a long-standing astronomical question.
