Comet C/2023 A3 (Tsuchinshan-ATLAS) could soon shine very bright in Earth's skies

A decade ago, on Sept. 21, 2014, NASA's MAVEN (Mars Atmospheric and Volatile EvolutioN) spacecraft entered orbit around Mars, beginning its ongoing exploration of the Red Planet's upper atmosphere. The mission has produced a wealth of data about how Mars' atmosphere

Two new studies provide two new answers to the mystery of where Mars's water disappeared to.

Imagine a thin film, just nanometers thick, that could store gigabytes of data—enough for movies, video games, and videos. This is the exciting potential of ferroelectric materials for memory storage. These materials have a unique arrangement of ions, resulting in two distinct polarization states analogous to 0 and 1 in binary code, which can be used for digital memory storage.

There is a global water crisis, and it is not only about the dwindling supply of clean water. Contaminated drinking water exposes hundreds of millions of people worldwide to toxins, such as bacteria, heavy metals, pesticides and coronaviruses. This contamination imperils public health and can cause serious illnesses.

After our first run through the site of the first recognized interstellar meteor, IM1, we found plenty of volcanic dust on our magnetic sled, containing tiny particles less than a tenth of a…

Scientists detected a fast radio burst and gravitational waves from colliding neutron stars, becoming a black hole.

To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride bolometers are used as the detectors, despite their low operating temperature of 4 Kelvin (-269° Celsius).

The Perseverance rover has found strong evidence of organic material on Mars in what was once an ancient lake.

Internet of things (IoT) sensors can collect, store and communicate large volumes of information, which require effective security measures. Here, the authors report the realization of low-power edge sensors based on photosensitive and programmable 2D memtransistors, integrating sensing, storage and encryption functionalities.

As a result of corrosion, copper and silver release positively charged ions into their environment, which are harmful to bacteria in several ways and prevent their growth or kill them completely. This effect has long been exploited, for example by coating implants with these metals to prevent bacterial infections. There are some tricks that can be employed to release even more ions and intensify this effect. For…

Saturday France connected a new nuclear reactor to its grid "for the first time in a quarter century..." reports Bloomberg, "adding low-carbon electricity supply at a time when a sputtering economy has made demand sluggish." The Flamanville-3 reactor — the first such addition since Civaux 2 wa...

The alliance brings together several key players, including German firm Manz AG, Taiwan's Scientech for wet etching, Hyawei Optronics for AOI inspection, as well as Lincotec, STK...

Scientists have identified the main process, called impact vaporization, that formed the moon's atmosphere and continues to sustain it today.

How a cosmic dust storm is helping New Horizons to redraw the map of the outer solar system.

New research illuminates the strange evolution of Be stars, which spin like maniacs and form discs like Saturn

A cosmologist gives us a blow-by-blow account of the hellishly hot—and ultimately chilling—end.

Describes how windows can be made transparent or opaque at the flick of a switch.

Casimir forces are normally attractive and cause stiction, that is, static friction preventing surfaces in contact from starting to move. Now, a system exhibiting tunable repulsive critical Casimir forces, relevant for the development of micro- and nanodevices, is demonstrated.

A scientist in Ukraine warns that the reactor at Europe's largest nuclear power station is designed to protect against some threats, but not shelling
