Solar orbiter solves magnetic switch puzzle

science and exploration 12/09/2022 444 opinions 11 Likes With data from the Sun’s closest path to date, the ESA/NASA Solar Orbiter spacecraft has found compelling evidence about the origin of magnetic switches, and suggests how its physical formation mechanism could help accelerate the solar wind. The Solar Orbiter has made the first remote sensing observations … Read more

We made a map of dark matter but we still don’t know what it is, and that’s okay

In early August, astronomers announced that they had created a map of dark matter — the mysterious and invisible matter that astronomers say underlies all structures in the universe — linked to some of the oldest galaxies in the universe. Articles reporting on the achievement described an innovative observing technique: searching for tiny distortions of … Read more

Astronomers find spiral stars at the center of a star cluster

NASA’s Hubble has discovered young stars rising to the center of a massive group of stars in the Small Magellanic Cloud. The outer arm of the spiral in this massive, oddly shaped stellar nursery called NGC 346 may be fueling star formation in a river-like motion of gas and stars. The chemical composition of the … Read more

The LICIA Cube will witness the collision of DART with the asteroid Dimorphos in real time

When NASA’s DART spacecraft smashes into the asteroid Demorphos on Sept. 26, it will have a silent witness: an Italian cube called LICIACube will witness the ground-breaking real-time experiment of excited scientists on Earth. LICIACubeor the Italian Light Asteroid Imaging Cube, is a small 31-pound (14 kg) satellite that has been able to ride Arrow … Read more

Microscope control automation for imaging biological events

Fluorescence microscopy seeks to collect data on specific biological events. However, the event-specific content that can be collected from a sample is limited, especially for rare or random processes. This is due in part to photobleaching and phototoxicity, which limit imaging speed and duration. EPFL Biophysicists have already found a way to automate microscopic control … Read more

The land could be more habitable. We’ll just need to change the orbit of Jupiter: ScienceAlert

We have exactly one world, in all the universe, that we know for a fact to be hospitable to life: our world. So when we search for habitable planets in other planetary systems, outside our own corner of the galaxy, we often use Earth as an ideal. But a new study has revealed that Earth … Read more

The Internet was asked to name a probe for Uranus. Here’s how it ended: ScienceAlert

Requiring the Internet to name a scientific mission has become something of a tradition, but we think even the bravest might ask in a recent Twitter request. An unofficial Twitter account promoting future missions of ice giants in our solar system, Giant Ice Missionsasked for suggestions for a so-called probe sent to Uranus. Given the … Read more

How massive stars steal planets

Our Sun has a fairly lonely existence in the Milky Way. It sits on its own, four light-years away from the nearest star, with only the company’s planetary system. But it wasn’t always this way. We observe almost exclusively young stars in groups, the so-called stellar nurseries, brushing their shoulders with stellar siblings. Our Sun … Read more
