New Gravity Theory Challenges Big Bang Singularity Problem
A new theory called Quadratic Quantum Gravity extends General Relativity to extreme energies, removing the Big Bang singularity and predicting testable gravitational wave signals from the early universe.

Jupiter Was Once Twice Its Size - And Its Magnetic Field Could Fry Spacecraft
Jupiter's early evolution and gravitational influence played a crucial role in shaping the solar system's structure and planetary orbits, earning it the title of the solar system's "architect."

Magnetic Fields Could Significantly Influence Oscillations in Merging Neutron Stars, Study Finds
Magnetic fields may play a bigger role in neutron star mergers than previously thought. A new study using advanced simulations shows that these fields can shift or suppress oscillation frequencies, altering gravitational wave signatures. This discovery could change how astronomers decode post-merger signals and refine models of neutron star interio...

New Polar Cataclysmic Variable Identified by Astronomers: What You Need to Know
Astronomers have detected ZTF J0112+5827, a newly identified polar cataclysmic variable. This binary system, composed of a white dwarf and a low-mass donor star, features an 80.9-minute orbital period and a strong magnetic field of 38.7 MG. It lacks an accretion disk, with emissions mainly from its accretion stream and magnetic field lines. The sys...

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...

NASA Citizen Scientists Discover Mysterious Object Moving out of Milky Way at an Extremely High Speed
On August 15, 2024, NASA’s Backyard Worlds: Planet 9 project, featuring the contributions of dedicated citizen scientists, made a groundbreaking discovery: an object moving at an astonishing speed of 1 million miles per hour, which will soon escape the gravitational pull of the Milky Way. This hypervelocity object, catalogued as CWISE J124909.08+...

Nearly Perfect Einstein Ring 12 Billion Light-Years Away Spotted by NASA’s Webb Space Telescope
NASA's James Webb Space Telescope, the world's biggest and most powerful space science telescope, captured an Einstein ring, which is located nearly 12 billion light-years away, is the result of the gravitational lensing phenomena caused by the gravitational field from a massive object wraps space and deflects light from a distant galaxy behind it.

Juno's Study Provides Insight on Jupiter's Composition, Gravitational Field
A new study has researched about Jupiter's metal concentration and distribution, suggesting that the planet ate a lot of rocky planetesimals when it was young. The authors sought to use Juno's Gravity Science experiment to investigate the metals in the planet's atmosphere. Jupiter's atmosphere isn't as homogeneous as originally imagined, according ...

NASA's Hubble Captures a Pair of Interacting Galaxies Forming the Number '10' in Space
In its more than 30 years of service, NASA's Hubble Space Telescope has made over 1.3 million observations of intriguing cosmic events and bodies. It once captured a pair of gravitationally interacting galaxies called Arp 147, using its prime working camera – the Wide Field Planetary Camera 2 (WFPC2). The “Hubble Classic” image has been again...
