Today Curiosity is doing a little bit of everything: some contact science, some targeted science, and a little driving. When we started planning this morning, we had a beautiful view of the small ledge in front of us, named "The Prow," which shows some amazing layering. We also can see some disturbances in the sand that may be sliding caused by our approach.

Planets like Earth, Jupiter, and Saturn with global magnetic fields of their own are surrounded by so-called radiation belts: Trapped in the magnetic field, fast moving charged particles such as electrons, protons, and heavier ions whiz around thus forming the invisible, torus-shaped radiation belts. With their high velocities reaching almost the speed of light, the particles can ionize other mo

An international team of researchers, led by postgraduate student Alexis Andres, has found that the black hole at the centre of our galaxy, Sagittarius A*, not only flares irregularly from day to day but also in the long term. The team analysed 15 years' worth of data to come to this conclusion. The research was initiated by Andres in 2019 when he was a summer student at the University of Amster

The days of the U.S.-Soviet Space Race are over, and the domain of space exploration is expanding daily to include more countries than ever before. With the advent of private companies such as Elon Musk's SpaceX, which aim to reduce the costs of space transportation, expeditions into our extraterrestrial surroundings are no longer limited to just two contenders.

Every living thing requires energy. This is also true of microorganisms. This energy is frequently generated in the cells by respiration, that is by the combustion of organic compounds, in other words: food. During this process, electrons are released which the microorganisms then need to get rid of. In the absence of oxygen, microorganisms can use other methods to do so, including transporting

An international team of astronomers has discovered what could be the early sign of a background signal arising from supermassive black holes, observed through low-frequency gravitational waves. These scientists are comparing data collected from several instruments, including the National Science Foundation's Green Bank Telescope (GBT.)

Webb has begun the detailed process of fine-tuning its individual optics into one huge, precise telescope.
Engineers first commanded actuators - 126 devices that will move and shape the primary mirror segments, and six devices that will position the secondary mirror - to verify that all are working as expected after launch. The team also commanded actuators that guide Webb's fine steering

A solar eclipse over the Arctic created changes in auroras in both of Earth's hemispheres due to connections through the planet's magnetic field, according to a new study. The new work could help scientists predict changes in the near-Earth environment that can interfere with satellite communication.
