IceCube Traces High-Energy Neutrino to Distant Starburst Galaxy
Scientists have identified the source of a high-energy neutrino detected by IceCube in 2021. The particle originated from a distant starburst galaxy known as Shadow Blaster, suggesting that intensely star-forming galaxies can act as powerful cosmic accelerators without relying on active black holes.

Astronomers Discover Why Massive Galaxies Died Early in the Universe
Astronomers have discovered a powerful galactic wind in the merging galaxy system CRISTAL-02. The outflow is removing star-forming gas faster than it can be replenished, providing the first direct evidence for a mechanism that may have shut down star formation in massive early galaxies.

Astronomers Detect Star-Forming Fuel in a Galaxy 13 Billion Light-Years Away
Using ALMA and the Very Large Array, astronomers directly detected a massive reservoir of molecular gas in REBELS-25, a galaxy from just 700 million years after the Big Bang. The finding provides the clearest evidence yet that some early galaxies were already loaded with the fuel needed for rapid star formation.

SETI Scientists Searched Interstellar Comet 3I/ATLAS for Alien Signals
SETI researchers used the Allen Telescope Array to scan interstellar comet 3I/ATLAS for artificial radio signals. No techno-signatures were detected, but the observations improved methods for future searches.

A Visitor from Another Star: Interstellar Comet Reveals Alien Origins
Observations of 3I/ATLAS reveal high levels of heavy water, suggesting it formed in an extremely cold star system. The discovery offers new insights into how planets form beyond our solar system.

Astronomers Detect Exceptionally High "Alcohol" Levels In Interstellar Comet 3I/ATLAS
The comet contains higher levels of this simple alcohol than almost all known comets from our solar system.

New ALMA Images Reveal Complex Rings Left Behind by Planet Formation
Astronomers used ALMA to capture unprecedented images of young exoplanetary systems. The ARKS survey mapped 24 debris disks, revealing rings, gaps and collisions that trace planetary evolution. These snapshots expose chaotic transitional stages, helping scientists understand how newborn planets mature into stable systems like our own Solar System t...

A Massive Black Hole Starved Pablo’s Galaxy, Ending Its Star Formation
Astronomers using the James Webb Space Telescope and ALMA have uncovered how a massive black hole shut down star formation in Pablo’s Galaxy. Powerful winds expelled gas at hundreds of kilometres per second, leaving almost no cold fuel behind. The findings suggest many early galaxies did not die explosively, but were slowly starved by their centr...

Astronomers Discover Shockingly Hot Young Galaxy Cluster That Defies Theory
Astronomers have identified an exceptionally hot galaxy cluster forming just 1.4 billion years after the Big Bang. Observations reveal gas temperatures far exceeding theoretical limits, suggesting an unexpectedly violent early formation. The discovery challenges standard models of galaxy cluster evolution and points to intense activity from starbur...

Extreme Star Factory: ALMA Detects Galaxy Y1 Forming Stars 180 Times Faster Than the Milky Way
Using ALMA’s ultra-sensitive Band 9 observations, astronomers identified galaxy Y1 as an extreme star-forming system in the early universe. Producing stars at 180 solar masses per year, Y1 reveals how intense, short-lived starbursts helped shape young galaxies and may have been more common than previously believed.

How Hot Was the Universe 7 Billion Years Ago? Scientists Now Have an Answer
Japanese astronomers using ALMA data have found the universe was about twice as hot 7 billion years ago, with a temperature of 5.13 K compared to today’s 2.7 K. The finding aligns perfectly with Big Bang predictions that the Universe cools as it expands, providing the most precise mid-epoch measurement yet and reinforcing confidence in standard c...

Keio University Team Measures Ancient Cosmic Temperature, Confirming Big Bang Prediction
Using ALMA, Keio University scientists measured a 5.13 K cosmic background temperature from 7 billion years ago—matching Big Bang predictions of universal cooling. This precise reading, based on quasar absorption data, is the most accurate at that epoch and offers strong confirmation of how the Universe’s temperature decreases over time.

James Webb Telescope Spots Evidence of a Black Hole Carving a Massive Scar Through a Galaxy
Astronomers using JWST and ALMA discovered a 20,000-light-year-long contrail in galaxy NGC 3627. Scientists believe it was carved by a massive black hole traveling through the galactic disk, leaving behind a turbulent scar of dust and gas that may offer new clues to galaxy evolution.

"Only Perseverance Is Required": What Shubhanshu Shukla Said To Students In Lucknow
"The entire landscape is changing, and I think the future is extremely bright," said astronaut and Indian Air Force Group Captain Shubhanshu Shukla here on Monday, while stressing that it was only perseverance that has defined his success.

Devil Comet’s Water Matches Earth, Strengthening Theory of Cosmic Origins
Astronomers discovered that the water in Comet 12P/Pons-Brooks, known as the “Devil Comet,” is nearly identical to Earth’s. Using ALMA and IRTF data, they mapped cometary water for the first time. The findings bolster the theory that comets delivered water to Earth, enabling life’s emergence.
