Earth's Spin Is Speeding Up, Making Your Days Shorter: Report
In the coming weeks, Earth will experience slightly shorter days due to changes in the moon's position.

Very Massive Stars Blow Away Outer Layers in Powerful Winds Before Black Hole Collapse
Massive stars may lose much more mass than expected before collapsing into black holes. A new study reveals that their powerful stellar winds strip outer layers early, reshaping theories of star evolution, black hole formation, and gravitational wave events. This research challenges previous models and helps explain observed features of stars like ...

New Theory Challenges Black Hole Singularities, But Critics Raise Red Flags
A new black hole theory proposes a fix to the long-standing singularity paradox by modifying gravity equations. But scientists like Nikodem Poplawski argue that the model lacks observational support and rests on speculative assumptions. He suggests future data from gravitational waves or the cosmic microwave background may one day help us uncover t...

Two Galaxy Clusters That Collided Previously Are All Set To Smash Again
Despite their enormous distance, the galaxy clusters are gravitationally bound and slowly turning back for another high-speed impact.

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."

Polaris Wasn’t Always the North Star: How Earth’s Wobble Shifts the Celestial Pole
Earth’s 26,000-year axial precession gradually shifts the celestial pole, replacing Polaris with new North Stars over millennia. Stars like Thuban, Kochab, Errai, and Vega have taken turns guiding humanity, and more will follow. According to NASA, gravitational forces cause this cosmic wobble, reminding us that even the seemingly constant night s...

China Uses Gravitational Slingshots to Rescue Two Satellites Stuck in Orbit for 123 Days
After a rocket malfunction left two satellites spiralling in the wrong orbit, Chinese engineers turned to gravitational slingshot manoeuvres for a 123-day rescue mission—successfully restoring them and advancing China's ambitions in space autonomy.

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...

James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus
A striking new image from the James Webb Space Telescope reveals an Einstein ring in the Hydrus constellation. The phenomenon occurs when a massive foreground galaxy bends light from a hidden background galaxy, forming a near-perfect ring. This effect, predicted by Einstein’s theory of general relativity, helps astronomers study galaxies from the...

ESA’s Euclid Telescope Releases First Data, Mapping 26 Million Galaxies
ESA’s Euclid telescope has released its first dataset, mapping 26 million galaxies within a week. The observations include deep-field images, a survey of 380,000 galaxies, and 500 new gravitational lens candidates. Scientists will continue tracking cosmic evolution over six years. The dataset, currently 35 terabytes, is expected to grow to 2 peta...

New Dark Matter Hypothesis Suggests Ionisation Clue in Milky Way’s Core
Researchers propose that an overlooked dark matter candidate may explain unusual ionisation levels in the Milky Way’s Central Molecular Zone (CMZ). This theory suggests that lightweight, self-annihilating dark matter particles could be producing electrons and positrons, influencing cosmic chemistry. The findings challenge conventional views, offe...

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...

Black Hole Singularities May Not Exist, Say Scientists
A new study questions the existence of black hole singularities, suggesting refinements to Einstein’s equations using quantum gravity concepts. Researchers argue that infinite density points may not be real, replacing them with highly curved but finite regions of space-time. While direct observation remains difficult, gravitational waves and earl...

X-ray Signal from Helix Nebula Suggests Planet Was Destroyed by White Dwarf
Astronomers have traced decades-old X-ray emissions from the Helix Nebula to a white dwarf possibly consuming planetary debris. Reports suggest a Jupiter-like planet may have been torn apart by the star’s intense gravitational forces. Data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton indicate that remnants of the destroyed plane...
