Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion years after the Big Bang, lies beside a 12,000-parsec-long filament containing multiple galaxies that are expected to merge within a few hundred million years.
Millions of people across the UK marveled at the spectacular northern lights that lit up the night sky in May 2024. But while the display captivated skywatchers, the geomagnetic storm behind it also served as the biggest test in a generation of the UK's preparedness for severe space weather. So did it pass?
The moon is 384,000 kilometers (239,000 miles) away from Earth, but one of the best places to study its surface is much closer to home. Western planetary scientist Catherine Neish and PhD candidate Sashank Vanga traveled to Hawai'i Volcanoes National Park in June to investigate lava flows that could reveal new clues about the moon's volcanic past.
NASA MAVEN (Mars Atmosphere and Volatile Evolution) mission scientists have uncovered a key puzzle piece in understanding certain types of auroras on Mars, finding that they form in a similar way to Earth–based auroras.
NASA is about to launch a space observatory that could help settle some of the biggest mysteries in modern astronomy. The Nancy Grace Roman Space Telescope will study how the universe began, what it is made of and how it has evolved over time.
Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio spectrum that has not recently been explored.
Venus is an inhospitable place, with temperatures soaring to several hundred degrees Celsius (hundreds of degrees Fahrenheit) and no oceans like those on Earth. Planetary scientists long believed Venus was geologically dormant. However, recent research indicates that Venus remains geologically "alive" and even hosts active volcanoes.
The worlds of the solar system are exciting and, so far, mostly pristine places for planetary scientists to study. As space missions continue to travel to Mars, Europa, asteroids and other worlds, questions arise about keeping them safe for continued exploration and observation.
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the findings was submitted to the arXiv preprint server on July 13.
UK astronomers are a step closer to playing a leading role in NASA's search for alien life in the coming decades as they continue developing one of the core instruments of the Habitable Worlds Observatory (HWO). The exciting mission—the U.S. space agency's next flagship space telescope after the Nancy Grace Roman Space Telescope—is expected to launch in the 2040s.
A careful statistical comparison of observations recorded by NASA's Juno mission and the Planetary Science Institute's Io Input Output observatory (IoIO) shows that IoIO observations reliably predict the density of Jupiter's plasma disk, an important part of Jupiter's magnetosphere, according to a new Geophysical Research Letters paper co-authored by Planetary Science Institute Senior Scientist Jeff Morgenthaler. Jian-Zhao Wang of the University of Colorado Boulder is the paper's lead author.
Europa, one of Jupiter's icy moons, has long fascinated scientists because of what may lie beneath its frozen shell: a global ocean of liquid water. That hidden ocean has made Europa one of the most compelling places in the solar system to study the conditions that might support life. But new research led by Rutgers scientist Lujendra Ojha suggests one of the most promising shortcuts to Europa's ocean may be far more complicated than previously thought.
Ancient samples from the moon's far side are helping scientists uncover how asteroid impacts shaped the early solar system. The findings challenge decades of thinking about when those impacts occurred and offer new insights into the conditions that influenced Earth's evolution.
Chinese astronomers report the detection of a peculiar optical transient event that occurred in the center of a dwarf galaxy. The newly discovered event, designated AT2019ijn, is a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission. The finding was detailed in a paper published July 6 in The Astrophysical Journal Letters.
SpaceX's mammoth Starship rocket blasted off Friday on another test flight stretching halfway around the world, this time releasing 20 of the most advanced Starlinks.
