Major collaboration reveals new insights on binary star systems
Write a comment
Oxford UK (SPX) Mar 06, 2023
Scientists have long been intrigued by X-ray binary star systems, where two stars orbit around each other with one of the two stars being either a black hole or a neutron star. Both black holes and neutron stars are created in supernova explosions and are very dense - giving them a massive gravitational pull. This makes them capable of capturing the outer layers of the normal star that orbits ar

Dark matter halos: the key to understanding galaxies

Buenos Aires, Argentina (SPX) Mar 06, 2023
We have come a long way in understanding the universe around us, thanks to current technological advances, such as the construction of huge telescopes or satellites with increasingly powerful instruments. However, it is disturbing that most of the universe components (matter and energy) are still unknown to us. In the "recipe" to "build" a universe like ours, we have to put two ingredients that

The outburst of a neutron star reveals the nature of phenomena only observed in black holes

La Laguna, Spain (SPX) Mar 06, 2023
X-ray binaries are systems formed by a compact object, a neutron star or a black hole, and a star of a similar size to the Sun. The compact object swallows matter from the companion star through a disk that emits large amounts of light, especially in X-rays. This process in which the compact object attracts matter, known as accretion, usually occurs in violent eruptions during which the system b

Humanity's quest to discover the origins of life in the universe

Zurich, Switzerland (SPX) Mar 06, 2023
"We are living in an extraordinary moment in history," says Didier Queloz, who directs ETH Zurich's Centre for Origin and Prevalence of Life and the Leverhulme Centre for Life in the Universe at Cambridge. While still a doctoral student Queloz was the first to discover an exoplanet - a planet orbiting a solar-type star outside of Earth's solar system. A discovery for which he would later receive

Ozone-measuring Instrument on NOAA-21 Satellite Captures its First Images

Washington DC (SPX) Mar 06, 2023
On February 9, 2023, an ozone-measuring instrument on the recently launched NOAA-21 satellite opened its doors and, over the course of a week, gathered data for its first global image. The Ozone Mapping and Profiler Suite (OMPS) consists of three sensors that monitor Earth's ozone layer and track its recovery.

What we learned from the asteroid-smashing DART mission

Boston MA (SPX) Mar 06, 2023
On Sept. 26, 2022, at precisely 6:14 p.m. ET, a box-shaped spacecraft no bigger than a loveseat smashed directly into an asteroid wider than a football field. The planned impact knocked the space rock off its orbit, showing for the first time that an asteroid can potentially be deflected away from Earth.
The spacecraft was the key part of DART, NASA's Double Asteroid Redirection Test, whic

House hunting on Mars could soon become a thing, and researchers at the University of Arizona are already in the business of scouting real estate that future astronauts could use as habitats. Researchers in the UArizona College of Engineering have developed technology that would allow a flock of robots to explore subsurface environments on other worlds.

NASA delivers hardware for commercial lunar payload mission
Write a comment
Ever wondered how your phone knows exactly where you are? Or how it can provide directions from one place to another?
In the United States, we rely on the Global Positioning System (GPS)—a satellite constellation orbiting Earth that provides precise location and timing information. What a lot of people don't know is that GPS is just one constellation of location and timing satellites. There are currently six GPS-like systems, known as global navigation satellite systems, or GNSS, that provide navigation services to Earthlings traveling the globe.
But what if we could use these Earth-based systems beyond our planet?
In 2024, as part of the NASA Commercial Lunar Payload Services (CLPS) initiative, Firefly Aerospace will land the "Blue Ghost" lander on the lunar surface.

First ever Canadian lunar rover will hunt for water ice on the moon
Write a comment
Edmonton, Canada (SPX) Mar 06, 2023
The first ever Canadian rover to set wheels on the moon is currently under construction for a mission set to launch as early as 2026. The rover will explore the south polar region of the moon in a search for water ice in the lunar soil.
Rovers are simply "mobile robotic vehicles that allow us to explore the surfaces of other planets," explains Chris Herd, a professor in the Department of E

A joint research team led by Dr. Xiaohui Fu and Dr. Zhongchen Wu from Shandong University, China, proposed a new carbonate formation mechanism in Martian dust activities based on simulation experimental studies.
