German astronomers have measured the magnetic field in the vicinity of a supermassive black hole. A bright and compact feature of only 2 light-days in size was directly observed by a world-wide ensemble of millimeter-wave radio telescopes in the heart of the active galaxy NGC 1052.
In the last century, humans realized that space is filled with types of light we can't see - from infrared signals released by hot stars and galaxies, to the cosmic microwave background that comes from every corner of the universe. Some of this invisible light that fills space takes the form of X-rays, the source of which has been hotly contended over the past few decades.
Supermassive black holes, millions to billions of times the mass of our Sun, are found at the centers of galaxies.
Why the universe is dominated by matter today, instead of being comprised of equal parts matter and antimatter, is one of the most intriguing questions in all of science.
International teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to explore the distant corner of the Universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF).
An experiment to explore the aftermath of cosmic dawn, when stars and galaxies first lit up the universe, has received nearly $10 million in funding from the National Science Foundation to expand its detector array in South Africa.
Using ESO's Very Large Telescope and other telescopes a fossilised remnant of the early Milky Way harboring stars of hugely different ages has been revealed by an international team of astronomers.
In research published today, Australian scientists have taken a critical step towards understanding why different types of galaxies exist throughout the universe.
An international team using ALMA, along with ESO's Very Large Telescope and other telescopes, has discovered the true nature of a rare object in the distant universe called a Lyman-alpha blob.
Researchers have detected two massive holes which have been 'punched' through a stream of stars just outside the Milky Way, and found that they were likely caused by clumps of dark matter, the invisible substance which holds galaxies together and makes up a quarter of all matter and energy in the universe.
The mystery of a rare change in the behaviour of a supermassive black hole at the centre of a distant galaxy has been solved by an international team of astronomers using ESO's Very Large Telescope along with the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory.
Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects.
The first catalogue of more than a billion stars from ESA's Gaia satellite was published today - the largest all-sky survey of celestial objects to date.
An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed.
Two papers published by an assistant professor at the University of California, Riverside and several collaborators explain why the universe has enough energy to become transparent.
Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter.
This NASA/ESA Hubble Space Telescope has given us this stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right), shining like huge cosmic headlamps in the dark.
