NASA’s Perseverance Captures Dust-Filled Martian Whirlwind
The six-wheeled geologist spotted the twister as part of an atmospheric exploration of Jezero Crater. The lower portion of a Martian dust devil was captured moving along the western rim of Mars' Jezero Crater by NASA's Perseverance rover on Aug. 30, 2023, the 899th Martian day, or sol, of the mission.

Scientists observe the influence of gravity on antimatter for the first time
Scientists have demonstrated the existence of gravity between antimatter and Earth, reaffirming Albert Einstein's General Theory of Relativity. It is thought that Isaac Newton's historic work on gravity was inspired by watching an apple fall to Earth from a tree. But for decades, scientists have wondered what would happen to an "anti-apple" made of antimatter - would it fall in the same way if it existed? Until now, the question has left scientists with an incomplete picture of the Universe's gravitating content.

Cosmic Web Lights Up in the Darkness of Space
Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While astronomers have known about the cosmic web for decades, and even glimpsed the glow of its filaments around bright cosmic objects called quasars, they have not directly Galaxies in our universe condense out of swirling clouds of gas.

X-rays may tell us more about the origins of visiting space rocks
A research team led by a Yale astronomer has some advice for our next close encounter with a wandering, interstellar object. Check its X-rays on the way out. Since 2017, when a mysterious space rock known as -Oumuamua was spotted passing through Earth's solar system, researchers have become increasingly aware of the likelihood that interstellar objects cross through the solar system with some regularity.

NASA-Led Study Pinpoints Areas of New York City Sinking, Rising
Scientists using space-based radar found that land in New York City is sinking at varying rates from human and natural factors. A few spots are rising. Parts of the New York City metropolitan area are sinking and rising at different rates due to factors ranging from land-use practices to long-lost glaciers, scientists have found.

Listening to the Radio on the Far Side of the Moon
Key Takeaways Researchers can use the radio-quiet far side of the moon to listen for a never-before-heard signal from the "Dark Ages" of the universe. The LuSEE-Night experiment will act as a pathfinder for future experiments, testing equipment and techniques in the harsh lunar environment. The Berkeley Lab team is now building the experiment's antenna, which will head to the moon and hunt for radio waves.

Methane and carbon dioxide found in atmosphere of habitable zone exoplanet
Astronomers have for the first time discovered carbon-based molecules in the atmosphere of an exoplanet in the habitable zone. The international team, which includes Cardiff University astrophysicist Dr Subi Sarkar, used data from the James Webb Space Telescope (JWST) to detect methane and carbon dioxide in the atmosphere of K2-18 b. Orbiting a red-dwarf star 124 light years away in the constellation of Leo, K2-18 b is a 'sub-Neptune' exoplanet 2.6 times the size of Earth and 8.6 times the mass of Earth.

Statistics of the invisible
In order to obtain information about dark matter and dark energy from the huge amounts of data to be generated by the new ESA probe Euclid, Innsbruck astrophysicist Laila Linke and her team are using novel statistical methods. As soon as Euclid sends its first data to Earth, the researchers intend to have a tool ready to gain new Astronomical measurements revealed that an unknown world lies hidden among all the pretty stars, nebulae and galaxies.

Study of Exoplanet TRAPPIST-1 b reveals new insights into its atmosphere and star
Complex interplay between stellar activity and exoplanet characteristics revealed in study co-authored by McGill Professor Nicolas Cowan A team of astronomers has made a leap forward in our understanding of the intriguing TRAPPIST-1 exoplanetary system. Not only has their research shed light on the nature of TRAPPIST-1 b, the exoplanet orbiting closest to the system's star, but it has also shown the importance of parent stars when studying exoplanets.

JWST’s first spectrum of a TRAPPIST-1 planet
U-M astronomer played key role in study of exoplanet that reveals new insights into its atmosphere and star This artistic representation of the TRAPPIST-1 red dwarf star showcases its very active nature. The star appears to have many stellar spots (colder regions of its surface, similar to sunspots) and flares.

Abundance of Milky Way-like galaxies in early Universe, rewriting cosmic evolution theories
Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research published today. Using the James Webb Space Telescope (JWST), an international team of researchers including those at The University of Manchester and University of Victoria in Canada discovered that galaxies like our own Milky Way dominate throughout the universe and are surprisingly common.

NASA Releases Independent Review’s Mars Sample Return Report
The agency established the board in May 2023 to evaluate the technical, cost, and schedule plans prior to confirmation of the mission's design. An Independent Review Board (IRB) looked at NASA's current plans and goals of the first mission to return samples from Mars, and NASA is establishing a team to respond.

Using machine learning to close Canada’s digital divide
Researchers use AI to detect potential problems with satellites before they happen Rural and remote communities in Canada often rely on satellites to access the internet, but those connections are fraught - with many glitches and service interruptions because the technology can be unreliable. The inequity in internet access between these communities and those who live in cities is an ongoing problem with myriad consequences for Canada's economic productivity.

Hiccups in the starry nursery
Before the light comes on and a new star shines, enough gas and dust must accumulate in a very small space for a star's energy source, nuclear fusion, to ignite. This by no means happens at rest. Matter swirls around, and before the star sees the light of day, violent birth labour is not uncommon. The new James Webb Space Telescope has turned its lens on such a spectacle, which reveals itself in unprecedented detail.

Venus on Earth: NASA’s VERITAS Science Team Studies Volcanic Iceland
The JPL-led international team used the island as a stand-in for Venus to test radar technologies that will help uncover the planet's ground truth. With its crushing atmospheric pressure, clouds of sulfuric acid, and searing surface temperature, Venus is an especially challenging place to study. But scientists know that observing its surface can provide key insights into the habitability and evolution of rocky planets like our own.

New recipes for origin of life may point way to distant, inhabited planets
Life on a faraway planet - if it's out there - might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. A team led by scientists at the University of Wisconsin-Madison has exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life.

New project to monitor satellites over Canada
As satellite count surges, Western team uses meteor tracking camera tech to track where they are in Earth's orbit As predicted by Captain Kirk, space is indeed the final frontier. But imagine if Starfleet couldn't launch the U.S.S. Enterprise because there was a traffic jam in Earth's orbit causing congestion or, worse, gridlock.

Physicist Looks to AI for New Answers to Universal Questions
The magical mystery of quantum mechanics thrills Beka Modrekiladze. The Carnegie Mellon University physics doctoral candidate sees artificial intelligence as the way to unlock its secrets. "I want to understand what space-time is made of," he said. "Is it fundamental, or is it something else? One of the most important goals in my life is to understand the universe on a deeper level." Quantum gravity is one way that Modrekiladze studies space-time, a model that joins the two concepts into a single idea.
