Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years away, according to a study led by Yongda Zhu, a postdoctoral researcher at the University of Arizona Department of Astronomy […] NASA began another practice launch countdown Tuesday for its first moonshot in decades with astronauts after making repairs to fix dangerous fuel leaks that already have bumped the flight into March. Go to Source A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of dusty, star-forming galaxies at the far edges of the universe that formed only a billion years after the Big Bang, believed to have occurred 13.7 billion years ago. The galaxies may represent a snapshot in […] Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams that trail behind them. They move quickly through their hot, dense galaxy cluster, and the gas within the cluster acts like a strong wind pushing […] Dark energy is one of those cosmological features that we are still learning about. While we can’t see it directly, we can most famously observe its effects on the universe—primarily how it is causing the expansion of the universe to speed up. But recently, physicists have begun to question even that narrative, pointing to results […] Scientists have produced the first global map and analysis of small mare ridges (SMRs) on the moon, a characteristic geological feature of tectonic activity. Published in The Planetary Science Journal Dec. 24, 2025, the analysis performed by scientists at the National Air and Space Museum’s Center for Earth and Planetary Studies and colleagues reveals for […] The United Arab Emirates announced on Tuesday that it would extend its Mars probe mission, now in its fifth year, for an additional three, underlining the oil-rich state’s space ambitions. Go to Source Using the Very Large Telescope (VLT), astronomers have discovered a compact binary system consisting of two white dwarfs in the center of a nearby globular cluster designated NGC 6397. The finding was presented in a paper published February 9 on the arXiv preprint server . Go to Source In the eastern Utah desert, carbon-dioxide-saturated water bubbles, sprays and foams from the ground. These cold-water geysers, sometimes called soda pop geysers, are a new and reliable Earth-based analog for scientists studying plume eruptions of ocean worlds in the outer solar system, according to new research led by Planetary Science Institute Senior Scientist Morgan Cable […] Researchers at The University of Manchester have developed a new way to design Earth-observation satellite missions that could help protect the space environment while continuing to deliver vital data for tackling global challenges, such as climate change, food production, supply chain vulnerabilities and environmental degradation. Go to Source A recent study showed that Mars was warm and wet billions of years ago. The finding contrasts with another theory that this era was mainly cold and icy. The result has implications for the idea that life could have developed on the planet at this time. Go to Source For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically expect to detect today? Go to Source Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver important information regarding the nature of this system. Go to Source The arrival of 3I/ATLAS in our solar system spawned multiple proposals for a rendezvous mission to study it up close. As the third interstellar object (ISO) ever detected, the wealth of information direct studies could provide would be groundbreaking in many respects. However, the mission architecture for intercepting an interstellar comet poses numerous significant challenges […] Southern Californians out on Saturday night for Valentine’s Day took a break from staring longingly into each other’s eyes to gaze at something else: a SpaceX rocket blazing across the early evening Southern California sky.
