Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a study led by the University of Warwick that peers into its future.
Astronomers have spotted a giant 'blinking' star towards the centre of the Milky Way, more than 25,000 light years away.
An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics--tiny flecks that can ride currents hundreds or thousands of miles from their point of entry
China's Chang'e-4 probe marked the first soft-landing of a spacecraft on the far side of the Moon, which always faces away from Earth. To communicate with ground stations, Chang'e-4 relies on Queqiao, a relay communication satellite that orbits a point behind the Moon and bridges Earth and Chang'e-4. In a recent review, researchers explain the design of Queqiao and depict the future of lunar relay communication systems.
Curtin University researchers have helped uncover the four billion year old story of a lunar sample brought from the Moon to Earth, by the manned Apollo 17 mission more than 50 years ago.
The Uttarakhand region of India experienced a humanitarian tragedy on Feb. 7, 2021, when a wall of debris and water barreled down the Ronti Gad, Rishiganga and Dhauliganga river valleys. This debris flow destroyed two hydropower facilities and left more than 200 people dead or missing. A self-organized coalition of 53 scientists, including researchers from the University of Washington, came together in the days following the disaster to investigate the cause, scope and impacts.
In the decade following their discovery in 2007, only 140 FRBs had been seen. Now, thanks to the launch of a large stationary telescope in the interior of British Columbia in 2018, the number of new FRBs detected has almost quadrupled -- for a total of 535. A McGill-led inter-university collaboration, has now put together the first CHIME/FRB catalogue.
New research in AGU's journal Geophysical Research Letters used a system for monitoring nuclear tests to track the infrasound from 1,001 rocket launches, identifying the distinctive sounds from seven different types of rockets. In some cases, like the Space Shuttle and the Falcon 9, the researchers were also able to identify the various stages of the rockets' journey (audio available).
New UArizona research finds that the target asteroid of NASA's Psyche mission may not be as metallic or dense as previously predicted, hinting that it might not be an exposed planetary core after all.
The moons of planets that have no parent star can possess an atmosphere and retain liquid water. Astrophysicists at LMU have calculated that such systems could harbor sufficient water to make life possible - and sustain it.
