The moons of planets that have no parent star can possess an atmosphere and retain liquid water. Astrophysicists at LMU have calculated that such systems could harbor sufficient water to make life possible - and sustain it.
At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region around the center of the galaxy. Even though these objects are thousands of millions of times smaller than their host galaxies our current view is that the universe can be understood only if the evolution of galaxies is regulated by the activity of these black holes, because without them the observed properties of the galaxies cannot be explained.
In a decade-long quest, scientists at Berkeley Lab, the University of Hawaii, and Florida International University uncover new clues to the origins of the universe - and land new chemistry for cleaner combustion engines.
The large radio telescope CHIME has detected more than 500 mysterious fast radio bursts in its first year of operation, MIT researchers report. The observations quadruple the number of known radio bursts and reveal two types of FRBs: one-offs and repeaters.
Astronomers have taken a big step forward in understanding the dark and violent places where stars are born. Over the past five years, an international team of researchers has conducted the first systematic survey of 'stellar nurseries' across our part of the universe, charting the more than 100,000 of these nurseries across more than 90 nearby galaxies and providing new insights into the origins of stars.
A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has completed the first census of molecular clouds in the nearby Universe. The study produced the first images of nearby galaxies with the same sharpness and quality as optical imaging and revealed that stellar nurseries do not all look and act the same. In fact, they're as diverse as the people, homes, neighborhoods, and regions that make up our own world.
Astrophysicists from the University of Bath in the UK have developed a new method for pinpointing the whereabouts of extremely rare extragalactic objects. They hope their technique for finding 'changing-look quasars' will take scientists one step closer to unravelling one of greatest mysteries of the universe - how supermassive black holes grow. Quasars are believed to be responsible for regulating the growth of supermassive black holes and their host galaxies.
Scientists have developed a new neural network capable of detecting coronal holes based on data from space observations. The new application opens up opportunities for improving the accuracy of space weather forecasting and provides valuable information for studying solar cycles.
A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR), Pune, and the Raman Research Institute, Bangalore, used the Giant Metrewave Radio Telescope to measure the atomic hydrogen gas content of galaxies 9 billion years ago. The new result is a confirmation of the group's earlier result, where they had measured the atomic hydrogen content of galaxies 8 billion years ago, and pushes our understanding of galaxies to even earlier in the universe.
No one knows what happened in the universe for its first 400,000 years, but a new paper suggests discovering the hypothetical particle axion could shed light on the early history of the universe. What's more, current dark matter experiments may have already detected it in its data.
