Space weather will delay your trains
Fluctuations in space weather are disrupting train signals and causing significant delays. A project investigating the effect of solar storms on railway signals will be presented this week at the National Astronomy Meeting (NAM 2022) by Cameron Patterson, a Ph.D. student at Lancaster University.
The sun's tendency to affect technology on Earth, as well as in space, is known as space weather. In railways, electric currents caused to flow in the Earth by solar activity can interfere with the normal operation of signals, turning green signals to red even when there is no train nearby.
Patterson says: "Most of us have at one point heard the dreaded words: 'your train is delayed due to a signaling failure,' and while we usually connect these faults to rain, snow and leaves on the line, you may not have considered that the sun can also cause railway signals to malfunction.

ESA’s newest launch system has faced its first full validation test, carrying LARES-2, a scientific mission of the Italian space agency ASI, and a secondary payload package of French, Italian and Slovenian research CubeSats.
Vega-C successfully completes inaugural flight
ESA’s new Vega-C rocket has completed its inaugural flight, placing main payload LARES-2 – a scientific mission of the Italian Space Agency ASI – into its planned orbit. Six research CubeSats from France, Italy and Slovenia flew as secondary payloads. The launch caps a multi-year effort by ESA, prime contractor Avio and industrial partners in 13 ESA member states to build on the heritage of its predecessor, Vega.
Vega-C: watch the launch

Undead planets: the unusual conditions of the first exoplanet detection
The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare. The new work will be presented tomorrow (Tuesday 12 July) at the National Astronomy Meeting (NAM 2022) by Iuliana Ni?u, a PhD student at the University of Manchester.

NASA on Tuesday unveiled its first full collection of images taken by the James Webb Space Telescope - showcasing the type photos that engineers had in mind when they first conceived of the telescope in the 1990s.
The space agency unveiled the collection of five images from the $10 billion telescope during an event late Tuesday morning at the Goddard Space Flight Center in Greenbelt, M Cosmic cliffs and dancing galaxies: Webb begins era of discovery
The cosmic cliffs of a stellar nursery and a quintet of galaxies bound in a celestial dance: NASA released the next wave of images from the James Webb Space Telescope Tuesday, heralding a new era of astronomy.
"Every image is a new discovery," said NASA administrator Bill Nelson. "Each will give humanity a view of the universe that we've never seen before."
