Did Black Hole Radiation Shape the Universe?
A study suggests that Hawking radiation, first proposed by Stephen Hawking, may have influenced the universe’s structure. According to reports, primordial black holes that existed in the early universe could have evaporated through Hawking radiation, impacting matter distribution. The research explores how these black holes might have shaped gala...

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...

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...

Water May Have Formed in the Universe 100 Million Years After Big Bang
A new study suggests water formed in the universe just 100–200 million years after the Big Bang, much earlier than previously estimated. Researchers examined ancient supernovas to understand how oxygen combined with hydrogen to create water. If confirmed, these findings could change perspectives on when the conditions for life first emerged. The ...

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...

JWST Identifies Cooling Gas in Phoenix Cluster, Unlocking Star Formation Process
The James Webb Space Telescope has detected the missing cooling gas in the Phoenix Cluster, a galaxy cluster located 5.8 billion light-years away. Researchers used the Mid-Infrared Instrument (MIRI) to identify gas at around 540,000 degrees Fahrenheit trapped in cavities within the cluster. This discovery resolves a long-standing mystery of how sta...

Webb Telescope Unveils Hidden Process Behind Star Formation in Phoenix Cluster
NASA’s James Webb Space Telescope has uncovered the missing link in star formation within the Phoenix galaxy cluster. By mapping intermediate-temperature gas, researchers identified a crucial phase of cooling that was previously undetected. This discovery explains why the cluster’s supermassive black hole does not fully prevent star formation, ...

SPHEREx Space Telescope to Map Cosmos in Infrared Light, Launching in February 2025
Set to launch in February 2025, NASA’s SPHEREx mission will provide a comprehensive map of the universe in infrared light. The telescope will examine 450 million galaxies and 100 million stars, shedding light on the universe’s formation, early conditions after the Big Bang, and the presence of water in planetary systems. SPHEREx will survey the...

JWST Detects Unexpectedly Massive Black Holes in the Early Universe
A new study led by Jorryt Matthee of ISTA reveals that black holes in early galaxies were significantly more massive than expected. Using JWST data, researchers found that some black holes accounted for nearly 10% of their galaxy's stellar mass—far exceeding the 0.01% ratio seen in modern galaxies. The findings challenge existing growth models, s...

Researchers Spot Unusual, Overmassive Globular Clusters in Ultra-Diffuse Galaxy FCC 224
A new study has uncovered an unexpected globular cluster system in FCC 224, an ultra-diffuse galaxy located in the Fornax cluster. Using data from the Hubble Space Telescope and the Keck Cosmic Web Imager, researchers found that FCC 224 hosts luminous, overmassive globular clusters with unusual properties. The galaxy’s star clusters exhibit narro...

NASA SPHEREx Telescope to Map the Universe and Search for Life’s Ingredients
NASA’s SPHEREx mission, set to launch aboard a SpaceX Falcon 9 rocket on February 27, aims to explore the origins of the universe and the formation of galaxies. Using near-infrared light, the telescope will study over 450 million galaxies and 100 million stars in the Milky Way. It will also search for water and organic molecules in regions where ...

Astronomers Capture Supermassive Black Hole Plasma Jets at Birth
For the first time, plasma jets from a supermassive black hole have been observed in real time. Located 270 million light-years away in galaxy 1ES 1927+654, the jets traveled at one-third the speed of light. Emerging in 2024 after a radio flare in 2023, the jets broke through dense gas near the black hole, which has a mass 1.4 billion times that of...

Early Supernovas Could Have Created Water in the Universe, Paving the Way for Life 100 Million Years Post-Big Bang
A recent study suggests that supernova explosions, triggered by the death of early stars, could have created significant amounts of water just 100 million years after the Big Bang. Simulations of these early, massive stars show that their explosive deaths may have resulted in the formation of water molecules within the dense hydrogen and oxygen clo...

Astronomers Spot Hundreds of Hidden Supermassive Black Holes Using Infrared
Hundreds of hidden supermassive black holes have been identified using infrared observations, offering fresh insights into their role in galaxy formation. Researchers relied on data from NASA's Infrared Astronomical Satellite (IRAS) and the Nuclear Spectroscopic Telescope Array (NuSTAR) to detect emissions from black holes obscured by thick clouds ...
