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...

Unexpected Rotational Motion Detected in Ultra-Diffuse Galaxies of Hydra Cluster
Astronomers studying ultra-diffuse galaxies (UDGs) in the Hydra cluster have observed unexpected rotational movement in nearly half of the 30 galaxies examined. Spectroscopic data from the LEWIS programme, using the MUSE instrument on the Very Large Telescope, suggests that gravitational interactions with larger galaxies may influence their formati...

New Study Reveals How Pulsars Help Measure Dark Matter in the Milky Way
A breakthrough study has used pulsar acceleration data to measure dark matter density in the Milky Way. Previously, binary pulsars were the primary source of data, but now solitary pulsars have been included, doubling the dataset. The research also provides evidence of the Milky Way’s "wobble" due to interactions with dwarf galaxies. By mapping t...

Astronomers Spot Galaxy NGC 3640 With a Past of Consuming Smaller Galaxies
Recent observations of NGC 3640 reveal a history of merging with smaller galaxies. Located 88 million light-years away, the elliptical galaxy is suspected to be on a collision course with NGC 3641. The Very Large Telescope captured structural distortions, hinting at previous mergers. Researchers have identified ancient stars acting as fossil marker...

A Neptune-Like Exoplanet Is Racing Through Space at Record Speed
Scientists have detected an exoplanet racing through space at 1.2 million mph, making it the fastest known planet. The Neptune-sized world orbits a hypervelocity star, first hinted at in 2011 via gravitational microlensing. Astronomers, using Keck Observatory and Gaia data, have confirmed the system’s extreme speed, suggesting it may even leave t...

Physicists Discover Singularities-Free Black Holes Using Pure Gravity
Physicists at ICCUB have mathematically proven that black holes can form without singularities, eliminating the need for exotic matter. The study, published in Physics Letters B, demonstrates that higher-order gravitational corrections alone can generate regular black holes. This breakthrough challenges previous models and provides new insights int...

Scientists Discover Two New Supernova Remnants in a Surprising Location
Two previously unknown supernova remnants, J0624-6948 and J0614-7251, have been detected in the outskirts of the Large Magellanic Cloud. Their unexpected location suggests a higher-than-expected concentration of ionised gas, raising new questions about galactic evolution. Scientists propose that gravitational interactions between the Milky Way and ...

Weak Gravitational Lensing Examines Universe’s Structure: What You Need to Know
The universe's large-scale uniformity is under scrutiny through weak gravitational lensing. Researchers are analysing data from the Euclid Space Telescope to detect potential anisotropies in cosmic expansion. If confirmed, these findings could challenge the fundamental Cosmological Principle, which assumes the universe has no preferred direction. T...

Euclid Space Telescope Discovers Rare Einstein Ring, Revealing Dark Matter Secrets
The Euclid space telescope has detected a rare Einstein ring around galaxy NGC 6505, located approximately 590 million light-years from Earth. This phenomenon, resulting from gravitational lensing, allows scientists to study the distribution of dark matter within the lensing galaxy. The discovery aligns with Euclid's mission to map cosmic structure...

NASA's Juno Detects Io's Most Powerful Volcanic Eruption Yet
NASA’s Juno spacecraft has recorded the most powerful volcanic eruption on Io, Jupiter’s most volcanic moon. The eruption site, detected on 27 December 2024, is fueled by a massive magma chamber spanning 105,000 square kilometers. The heat energy released is estimated at 80 trillion watts, exceeding Earth’s total power output. The volcanic ac...
