This strange phenomenon is called “redshift.”

Unless Europe’s Large Hadron Collider coughs up a surprise, the field of particle physics may wheeze to its end.

CELESTA, the first CERN-driven satellite, successfully entered orbit during the maiden flight of Europe’s Vega-C launch vehicle. Launched by the European Space Agency from the French Guiana Space Centre (CSG) at 13.13 UTC on 13 July 2022, the satellite deployed smoothly and transmitted its first signals in the afternoon. Weighing one kilogram and measuring 10 centimetres on each of its sides, CELESTA (CERN latchup and radmon experiment student satellite) is a 1U CubeSat designed to study the effects of cosmic radiation on electronics. The satellite carries a Space RadMon, a miniature version of a well-proven radiation monitoring device deployed in CERN’s Large Hadron Collider (LHC). CELESTA has been sent into an Earth orbit of almost 6,000 kilometres.

July 15 (Reuters) — NASA and Russia’s space agency Roscosmos have signed a long-sought agreement to integrate flights to the International Space Station, allowing Russian cosmonauts to fly on U.S.-made spacecraft in exchange for American astronauts being able to ride on Russia’s Soyuz, the agencies said Friday.

“The agreement is in the interests of Russia and the United States and will promote the development of cooperation within the framework of the ISS program,” Roscosmos said in a statement, adding it will facilitate the “exploration of outer space for peaceful purposes.”

NASA and Roscosmos, the two-decade-old space station’s core partners, have sought for years to renew routine integrated crewed flights as part of the agencies’ long-standing civil alliance, now one of the last links of cooperation between the United States and Russia as tensions flare over the war in Ukraine.

Ahead of the Artemis I flight test, NASA is inviting media to its Johnson Space Center in Houston Friday, Aug. 5, for a detailed mission briefing and a behind-the-scenes look at facilities that will enable a long-term human presence at the Moon.

This intriguing observation from the NASA/ESA Hubble Space Telescope shows a gravitationally lensed galaxy with the long-winded identification SGAS J143845+145407. Gravitational lensing has resulted in a mirror image of the galaxy near the center of this image, creating a captivating centerpiece. A third distorted image of the galaxy appears as a bridge between them.

Gravitational lensing occurs when the mass of an enormous celestial body – such as a galaxy cluster – curves spacetime and causes the path of light from distant objects to visibly bend around it, as if by a lens. Appropriately, the body causing the light to curve is called a gravitational lens, and the distorted background object is referred to as being “lensed.” Gravitational lensing can result in multiple images of the original galaxy, as seen in this image, or in the background object appearing as a distorted arc or even a ring. Another important consequence of this lensing distortion is magnification, allowing astronomers to observe objects that would otherwise be too far away or be too faint to see.

Phase transitions in topologically non-trivial systems are characterized by changes of topological invariants, rather than conventional order parameters. Here, the authors propose a real-space topological phase transition upon pair annihilation of emergent monopoles inherent in chiral magnet MnGe.
