Super Earths are Quite Common Outside the Solar System, New Study Reveals
Using the microlensing technique, KMTNet studied the exoplanet, which is twice as big as Earth, yet smaller than Neptune. It is believed that there are more such super-Earths outside our solar system. It is common to have such planets orbiting their stars.

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...

Astronomers Detect Methane in the Atmosphere of the Nearest T Dwarf Star to Earth
Astronomers have detected methane in the nearest known T dwarf, offering new insight into its atmospheric composition. The study further highlights that the carbon abundance in the planet is estimated to be -1.5 dex, while the effective temperature could be around 1,000 K. The author of the paper further revealed that the low metallicity of the T ...

First Future Type 1a Supernova Detected: White Dwarf Pair to Collide in 23 Billion Years
Astronomers have discovered a pair of white dwarf stars located about 150 light-years from Earth that are on course to collide and produce a Type 1a supernova in approximately 23 billion years. This is the first such system identified near our region of the galaxy. With a combined mass of 1.56 solar masses, the stars are slowly spiralling toward ea...

Wolf-Rayet 104's Orbit Tilt Reduces Gamma-Ray Burst Threat, Study Finds
New research using Keck Observatory’s instruments confirms that the orbit of Wolf-Rayet 104 is tilted 30-40 degrees away from Earth, lowering concerns about a possible gamma-ray burst. Previously, it was believed that the system’s alignment could pose a risk. However, spectroscopy data now challenges these assumptions, raising new questions abo...

Hubble Telescope Captures NGC 4536, a Starburst Galaxy with Intense Star Formation
NASA’s Hubble Space Telescope has captured a striking image of NGC 4536, a starburst galaxy 50 million light-years away in the Virgo constellation. The galaxy’s sweeping spiral arms are filled with young blue star clusters and ionized hydrogen gas, indicating rapid star formation. Astronomers believe its bar-like structure channels gas toward t...

James Webb Space Telescope Captures Hourglass Nebula LBN 483 in Stunning Detail
The James Webb Space Telescope has captured unprecedented details of LBN 483, a nebula located 650 light-years away. The striking hourglass-shaped structure results from outflows driven by a forming binary star system. JWST’s infrared imaging and ALMA’s radio observations reveal how stellar winds, jets, and magnetic fields sculpt the nebula ove...

Smallest Galaxy Ever Found: Andromeda XXXV Defies Cosmic Evolution Models
Astronomers have discovered Andromeda XXXV, the smallest and faintest known galaxy, located 3 million light-years away. It challenges existing models of galaxy formation, as similar small galaxies were thought to be destroyed in the early universe. Researchers are studying how it retained conditions for star formation despite harsh cosmic environme...

Hubble Captures Stunning Infrared Image of Sh2-284, a Massive Stellar Nursery
Hubble’s latest image of the massive Sh2-284 nebula reveals young stars concealed within thick clouds of gas and dust. Using infrared imaging, astronomers have captured details previously obscured in optical wavelengths. The nebula’s low-metallicity composition provides a glimpse into the conditions of the early universe, shedding light on how ...

Supermassive Black Hole May Be Hiding in Large Magellanic Cloud, Scientists Suggest
A potential supermassive black hole may exist in the Large Magellanic Cloud, as per recent scientific findings. Researchers analysed hypervelocity stars moving at extreme speeds and found many could have been ejected from this neighbouring galaxy. The black hole is estimated to be around 600,000 times the mass of the Sun. If confirmed, this discove...

Study Reveals Evidence of Supermassive Black Hole Inside Nearby Galaxy
A study based on the trajectory of nine fast-moving stars observed at the fringes of the Milky Way provides strong evidence for the existence of a supermassive black hole inside the Large Magellanic Cloud.

Alpha Centauri May Have Sent Millions of Asteroids into the Solar System
A study proposes that Alpha Centauri could be contributing a significant number of asteroids to the solar system. Simulations indicate that around 50 objects from the neighboring star system may enter the Oort Cloud annually. While most pass through due to their high velocity, a few could travel inward. The frequency of such occurrences is expected...

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...

NASA’s SPHEREx Telescope Launching Aboard SpaceX Falcon 9 to Explore Cosmic Evolution
NASA’s SPHEREx telescope, launching on Feb 28 aboard a SpaceX Falcon 9, will map the entire sky in infrared, observing 450 million galaxies and 100 million Milky Way stars. The mission aims to uncover the large-scale structure of the universe, track icy molecules in interstellar space, and study cosmic inflation. Equipped with a spectrophotometer...

Hubble Captures Stunning Tarantula Nebula Image, Revealing Cosmic Dust and Star Formation
A new image from the Hubble Space Telescope highlights the Tarantula Nebula’s complex structure, featuring dense cosmic dust clouds and vibrant star-forming regions. This nebula, located 160,000 light-years away, plays a vital role in understanding stellar evolution. The captured details offer insights into how cosmic dust contributes to star and...
