An international team of astronomers has used NASA’s James Webb Space Telescope to study the disk of gas and dust around a young, very low-mass star. The results reveal the largest number of carbon-containing molecules seen to date in such a disk. These findings have implications for the potential composition of any planets that might form around this star.
Machine learning revolutionizes distance measurement in astronomy, providing precise estimates for gamma-ray bursts and aiding in cosmic exploration.
The advent of artificial intelligence (AI) has been hailed by many as a societal game-changer, as it opens a universe of possibilities to improve nearly every aspect of our lives.
Astronomers are now using AI, quite literally, to measure the expansion of our universe.

A super smart or “learned” controller that leverages data-intensive artificial intelligence (AI) and computer simulations to train portable, robotic exoskeletons.
The Expedition 71 crew at the International Space Station is gearing up for a spacewalk focused on scientific and maintenance tasks, including the installation of a spare pump and the retrieval of faulty communications hardware. Additionally, Commercial Crew astronauts have extended their stay to facilitate further systems checks on the Starliner spacecraft. Amidst these preparations, the crew continues to engage in routine health checks and scientific experiments across various modules of the station.
Aboard the International Space Station (ISS), the Expedition 71 crew is getting ready for a spacewalk this week while two Commercial Crew astronauts will spend a few extra days. In addition, the orbital residents continued their advanced space research and conducted eye and ear exams on Monday.
University of Missouri scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago.
In a new study, the Mizzou researchers have discovered that spiral galaxies were more common in the early universe than previously thought. The work appears in The Astrophysical Journal Letters.
“Scientists formerly believed most spiral galaxies developed around 6 to 7 billion years after the universe formed,” said Yicheng Guo, an associate professor in Mizzou’s Department of Physics and Astronomy and co-author on the study. “However, our study shows spiral galaxies were already prevalent as early as 2 billion years afterward. This means galaxy formation happened more rapidly than we previously thought.”
In a study published in The Astrophysical Journal, Prof. Zhou Xia from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences and collaborators have, for the first time, derived the dispersion relation for photons with nonzero mass propagating in plasma, and established a stringent upper limit for the photon mass at 9.52 × 10–46 kg (5.34 × 10–10 eV c-2) using data collected by ultra-wideband (UWB) receivers from pulsar timing and fast radio bursts (FRBs).
A study analyzing the properties of polarized light from 128 non-repeating FRBs reveals mysterious cosmic explosions originate in far-away galaxies like our own Milky Way.
New research from the University of Toronto utilizing data from the Canadian Hydrogen Intensity Mapping Experiment reveals that the majority of Fast Radio Bursts (FRBs) likely originate from environments similar to our Milky Way, with modest densities and magnetic fields. This finding contrasts with earlier studies which suggested that repeating FRBs come from highly magnetized areas.

Astronomers are expecting a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA.
“It’s a once-in-a-lifetime event that will create a lot of new astronomers out there, giving young people a cosmic event they can observe for themselves, ask their own questions, and collect their own data,” said Dr. Rebekah Hounsell, an assistant research scientist specializing in nova events at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement. “It’ll fuel the next generation of scientists.”
The expected brightening event, known as a nova, will occur in the Milky Way’s Corona Borealis, or Northern Crown constellation, which is located between the Boötes and Hercules constellations.
Dr. Adomas Valantinas: “What we’re seeing may be a remnant of an ancient climate cycle on modern Mars, where you had precipitation and maybe even snowfall on these volcanoes in the past.”
How unique is the climate of Mars compared to Earth? This is what a recent study published in Nature Geoscience hopes to address as a team of international researchers investigated how frost could form on the summits of volcanoes that comprise the Tharsis volcanic province on Mars. This study holds the potential to help researchers better understand the present-day water cycle on the Red Planet and could have implications for harnessing some of it for future human exploration, as well.
For the study, the researchers used more than 30,000 images from the European Space Agency’s Trace Gas orbiter and the European Space Agency’s Mars Express orbiter to analyze morning frost on the summits of Olympus Mons (Mars’ tallest volcano and the tallest planetary mountain in the solar system), Arsia and Ascraeus Montes, and Ceraunius Tholus. Additionally, the researchers used climate model simulations to ascertain if water could condense and form at these summits, as well.
