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...

   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...

   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...

   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...

   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.

   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 .

   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...

   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...

   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?

   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.

   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.

   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...

   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.

   NASA has let Axiom Space make four visits to the International Space Station and in January 2026 awarded it the right for the fifth visit next year, but on Feb. 12, the agency announced a new company would be allowed a private mission as well.

   The atmospheres of exoplanets have been a focal point of the field lately, with the James Webb Space Telescope taking a look at as many as it can manage. But time on the world’s most powerful space telescope is valuable, and getting a complete picture of any such atmosphere is difficult without...

   Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination between instruments. The teams that run the James Webb Space Telescope (JWST) and the upcoming Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) missions...

   Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. Recently, researchers at McGill University and ETH Zurich have described...

   It’s well established that the universe is expanding, but there’s serious disagreement among scientists over how fast it’s happening.

   The International Space Station returned to full strength with Saturday’s arrival of four new astronauts to replace colleagues who bailed early because of health concerns.

   In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around three years before fading dramatically and disappearing, leaving behind a shell of dust. Although a...

   Going to space is harsh on the human body, and as a new study from our research team finds, the brain shifts upward and backward and deforms inside the skull after spaceflight.

   A major theme in communist governments is the idea of central planning. Every five years, the central authorities in communist countries lay out their goals for the country over the course of the next five years, which can range from limiting infant mortality to increasing agricultural yield. China...

   When she was growing up, Sophie Adenot plastered her childhood bedroom with posters of rockets launching from Cape Canaveral.

   The next-generation spacesuit for NASA’s Artemis III mission continues to advance by passing a contractor-led technical review, as the agency prepares to send humans to the moon’s South Pole for the first time. Testing is also underway for the new suits, built by Axiom Space, with NASA astronauts...

   Hypothetical dark matter stars known as boson stars could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a strange event was observed in the depths of space. Called GW190521, the event sent out gravitational...

   A new crew rocketed toward the International Space Station on Friday to replace the astronauts who returned to Earth early in NASA’s first medical evacuation.

   The first solar eclipse of the year will grace Antarctica, and only a lucky few will get to bask or waddle in its glow.

   NASA’s Carbothermal Reduction Demonstration (CaRD) project has completed an important step toward using local resources to support human exploration on the moon. The CaRD team performed integrated prototype testing that used concentrated solar energy to extract oxygen from simulated lunar soil,...

   An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered supernova designated SN 2024abfl. Results of the observational campaign, presented February 4 on the preprint server arXiv, yield important insights into the properties of this...

   The Space Coast’s first human spaceflight of the year is on tap for early Friday morning as NASA and SpaceX aim to send up a mission to the International Space Station, and also bring back the rocket’s booster that could bring with it a sonic boom across Central Florida.
