Five Dwarf Galaxies Found in a Rare Alignment, Challenges Current Cosmic Models
A rare alignment of five dwarf galaxies, positioned around 117 million light-years away, has been discovered by astronomers. This grouping, which challenges existing models of galaxy formation, shows active star formation despite their small sizes. The galaxies, labelled D1 to D5, exhibit unique characteristics, including shared rotational motion a...

Astronomers Seek Binary Supermassive Black Holes in Galactic Centers
Astronomers have detected possible binary black holes at the centres of galaxies, using light patterns from active galactic nuclei as key indicators. The study of PG 1553+153, in particular, shows evidence of a 20-year variation, pointing to a system of two supermassive black holes. If confirmed, this could provide new insights into galaxy formatio...

MeerKAT Detects Gravitational Wave Background, Uncovering Cosmic Activity
Scientists using the MeerKAT Pulsar Timing Array have made a groundbreaking discovery, confirming the presence of a gravitational wave background in the universe. This unexpected phenomenon, detected with unprecedented precision, suggests that supermassive black hole collisions may occur more frequently than previously thought. By observing the sig...

New Study Challenges Presence of Intermediate-Mass Black Hole in Omega Centauri
Research published in Astronomy & Astrophysics revises earlier claims of an intermediate-mass black hole in Omega Centauri. Observed stellar velocities in the dense star cluster are now attributed to stellar-mass black holes. Pulsar data enabled scientists to refine their methods for detecting gravitational fields, offering deeper insights into the...

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...

Binary Star System D9 Found Orbiting Sagittarius A* Near Milky Way’s Core
Astronomers have detected a young binary star system, D9, orbiting Sagittarius A*, the supermassive black hole at the Milky Way's centre. This challenges previous assumptions about star survival near intense gravitational forces. The discovery was made using the European Southern Observatory's Very Large Telescope. Future research with advanced tel...

NASA’s Webb Telescope Reveals Firefly Sparkle, a Milky Way-Like Galaxy
The James Webb Space Telescope has captured the Firefly Sparkle galaxy, existing 600 million years after the Big Bang. This rare discovery showcases a galaxy similar in mass to the Milky Way during its early years. Unprecedented details were revealed using gravitational lensing and infrared imaging, highlighting 10 distinct star clusters within Fir...

Jupiter’s Moon Io Shows No Magma Ocean as New Findings Explain Volcanic Eruptions
NASA's latest findings indicate that Jupiter's volcanic moon Io does not have a global magma ocean beneath its surface, debunking previous theories. This conclusion comes from analysis of data from NASA's Juno spacecraft and archival observations from the Galileo mission. The study suggests that Io's interior is more solid than expected, with volca...

New Theory Suggests Gravitational Waves Could Solve Black Hole Information Paradox
A new study proposes a potential solution to the long-standing black hole information paradox, suggesting that black holes might leak information through gravitational waves. Researchers at the California Institute of Technology have explored how quantum nonlocality could connect the interior of a black hole with its exterior. This connection would...

Arecibo Observatory Data Helps SETI Uncover Secrets of Pulsar Signals and Cosmic Distortions
Data from the now-collapsed Arecibo Observatory continues to drive major discoveries in space science. Sofia Sheikh and her team from the SETI Institute utilised archived data to investigate the signals of pulsars—dense neutron stars emitting radiation like cosmic lighthouses. Their study focused on how these signals are distorted by interstellar...

Ancient Galaxy Collisions May Explain Formation of Massive Early Star Systems
Research published in Nature reveals that ancient galaxy collisions may have led to the creation of the universe’s largest star systems. Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), scientists studied over 100 galaxies undergoing intense star formation. These collisions are believed to have occurred 8 to 12 billion yea...

James Webb Telescope Breaks Record with Discovery of Early Galaxies Dating 200 Million Years After Big Bang
The James Webb Space Telescope has spotted five galaxy candidates dating back to 200 million years after the Big Bang. These findings could transform our understanding of early cosmic evolution. Discovered via gravitational lensing, these galaxies, if confirmed, predate known formations and offer vital insights into the universe’s infancy. Scient...

Dark Matter Could Be Linked to a ‘Dark Big Bang’, New Study Suggests
New research suggests that dark matter may have originated from a "Dark Big Bang," a cosmic event distinct from the standard Big Bang. Proposed by scientists at Colgate University, the theory explores scenarios where dark matter could have been introduced into the universe up to a year after the initial Big Bang. Unlike regular matter, dark matter ...
