Parallax Microlensing Free-Floating Stars in the Milky Way’s Bulge
The path of a light beam is bent by the presence of mass, as explained by General Relativity. A massive body can therefore act like…
Violent Neutron Star Collision Sends Gravitational Waves Shuddering Through the Fabric of Space and Time
A new collaborative study with the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) reveals a possible collision of two neutron stars earlier in…
Quasar Tsunamis Discovered – Highest Energy Outflows Ever Witnessed in the Universe
Using the unique capabilities of NASA’s Hubble Space Telescope, a team of astronomers led by Virginia Tech’s Nahum Arav has discovered the most energetic outflows…
Cosmic Bombs and Controversy: A New Theory of Magnetar Formation
Magnetars are neutron stars endowed with the strongest magnetic fields observed in the Universe, but their origin remains controversial. In a study published in Science…
Dark Matter Decay Ruled Out as Source of Mysterious Electromagnetic Signals Detected From Nearby Galaxies
Eighty-five percent of the universe is composed of dark matter, but we don’t know what, exactly, it is. A new study from the University of…
First High Sensitivity Dark Matter Axion Hunting Results From CAPP-8TB Haloscope
IBS Researchers Raising Their Flag in the Axion Dark Matter Field Researchers at the Center for Axion and Precision Physics Research (CAPP), within the Institute…
Cataclysmic Binaries: Observable Novae Are Just “Tip of the Iceberg”
New simulation-based study on sleeping cataclysmic binaries supports contested 35-year-old predictions, shows that observable novae are just “tip of the iceberg.” Almost 35 years ago,…
Mystery of Supermassive Black Holes Shortly After the Big Bang – Explanation Discovered
These space giants would not have had the time to develop in the young Universe. Yet, observations say they were already present; a new study…
Gravitational-Waves and Nuclear Physics Used to Obtain Best Measurement of Neutron Star Size
International team uses a novel approach combining gravitational-wave observations, multi-messenger astronomy, and nuclear physics to obtain the best measurement of neutron star size to date….
Colossal Dark Matter Halos Surround Massive Galaxies
About eighty-five percent of the matter in the universe is in the form of dark matter, whose nature remains a mystery, and the rest is…
Merger Between Two Stars Formed a Blue Supergiant, Led to Iconic Supernova Explosion
Simulations suggest that two stars came together to form a blue supergiant, which subsequently exploded. A supernova in a nearby galaxy may have originated from…
Astrophysicists Reveal a New Model of Our Solar System’s Protective Bubble, the Heliosphere
Boston University astrophysicist and collaborators reveal a new model of our heliosphere that’s shaped somewhere between a croissant and a beach ball. The heliosphere is…
Strange Orbits of ‘Tatooine’ Planetary Disks – Striking Orbital Geometries Around Binary Stars
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary…
Quasar Tsunamis Tear Across Interstellar Space Wreaking Havoc on Galaxies
Using the unique capabilities of NASA’s Hubble Space Telescope, a team of astronomers has discovered the most energetic outflows ever witnessed in the universe. They…
“Theory of Everything” Tested – NASA’s Chandra X-Ray Observatory Probes String Theory
Astronomers used Chandra to perform a test of string theory, a possible “theory of everything” that would tie all of known physics together. One of…
Path to Razor-Sharp Black Hole Images Discovered – Striking and Intricate Substructure
Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole. Today, a team of researchers…
