Chandra resolves NGC 6540’s mysterious X-ray flare into three separate sources
Using NASA’s Chandra X-ray spacecraft, astronomers have performed deep X-ray observations of a galactic globular cluster known as NGC 6540. The new observational campaign, described June 1 on the preprint server arXiv, focused on disentangling the nature of a peculiar X-ray flare emitted by the cluster about two decades ago.

June 13, 1983: Pioneer 10 leaves solar system
Pioneer 10 holds the titles for many “firsts”: It was NASA’s first mission to the outer planets, the first spacecraft to fly beyond Mars, the first to traverse the asteroid belt, and the first to fly past Jupiter. It was also the first spacecraft placed on a trajectory to escape the solar system into interstellarContinue reading “June 13, 1983: Pioneer 10 leaves solar system” The post June 13, 1983: Pioneer 10 leaves solar system appeared Continue ReadingJune 13, 1983: Pioneer 10 leaves solar system

Threads of underground fungal networks are long enough to reach beyond the Solar System
Hidden underground around the world lie 110 quadrillion kilometers of arbuscular mycorrhizal fungal networks—webs of ultra-thin threads that, if connected in a single line, would stretch almost a billion times the distance between the Earth and the sun, according to new research published in Science on Thursday. These fungal communities form intimate relationships with the roots of plants, which they provide with nutrients like phosphorus and nitrogen in exchange for carbon, 1 billion tons of which the networks sequester underground annually, previous research has found. If the fungal network wasn’t storing it, that carbon would be warming the atmosphere. But Continue ReadingThreads of underground fungal networks are long enough to reach beyond the Solar System

NASA Study Challenges Theories on Where the Ingredients for Life Came From
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution of these elements throughout the young solar system. The study, published in Science Advances, examines this history by looking at the ratio of phosphorus to nitrogen in iron meteorites and in younger objects known as chondrites.

Prominent filaments
📷 Mark Johnston from Scottsdale, Arizona A line of filaments march toward the limb of the Sun, which itself is bedecked with multiple prominences in this Hα image. Both phenomena are made of loops and tendrils of plasma that arch off the surface of the Sun; their varying appearance depends on the viewing geometry.

Scientist creates ‘mini‑universe’ to measure time without a clock
A University of Birmingham scientist has built a “mini-universe” that takes a step toward answering one of science’s biggest questions: “What is time?” Publishing his findings in Physical Review Research, Professor Giovanni Barontini shows how it is possible to measure the flow of time without using a clock at all. The new findings provide a scientific model in which a version of time emerges from the experiment itself.

The Smallest Window on the Sun
Every so often, the Sun hurls billions of tonnes of charged particles toward Earth in what are called coronal mass ejections and if a big one hits at the wrong moment, the consequences for satellites, power grids, and communications systems could be catastrophic. Our best defence is to predict them before they happen, and that means watching the Sun’s magnetic fields constantly and precisely. Now, a component smaller than a shirt button could transform how we do exactly that.
