Scientists observe Z-boson production with two associated photons

Posted by in category: particle physics

Circa 2016 o,.o.

An international group of physicists has observed Z-boson production with two associated photons with later Z decay to electrons, muons or neutrinos at the ATLAS experiment at the Large Hadron Collider (LHC) in CERN.

Observation of this extremely rare physics process, predicted theoretically in 1960s, further validates the Standard Model ℠, according to ATLAS experiment contributor Dimitrii Krasnopevtsev.

Analysis of a Martian meteorite reveals evidence of water 4.4 billion years ago

Posted by in category: space

A meteorite that originated on Mars billions of years ago reveals details of ancient impact events on the red planet. Certain minerals from the Martian crust in the meteorite are oxidized, suggesting the presence of water during the impact that created the meteorite. The finding helps to fill some gaps in knowledge about the role of water in planet formation.

There’s a longstanding question in about the origin of on Earth, Mars and other large bodies such as the moon. One hypothesis says that it came from asteroids and comets post-formation. But some think that water might just be one of many substances that occur naturally during the formation of planets. A new analysis of an ancient Martian adds support for this second hypothesis.

Several years ago, a pair of dark meteorites were discovered in the Sahara Desert. They were dubbed NWA 7034 and NWA 7533, where NWA stands for North West Africa and the number is the order in which meteorites are officially approved by the Meteoritical Society, an international planetary science organization. Analysis showed these meteorites are new types of Martian meteorites and are mixtures of different rock fragments.

World’s longest laser — 270 km long — created

Posted by in categories: engineering, internet

Circa 2009.

A 270-kilometre optical fiber has been transformed into the world’s longest laser, a feat its inventors believe will lead to a radical new outlook on information transmission and secure communications.

Engineering academics at Aston University, UK, are leading research into ultralong fiber lasers, to create a platform capable of delivering ‘next generation’ information transmission, including telecommunications and broadband.

Longest laser ranging experiment

Posted by in category: space

The McDonald Laser Ranging Station, near Fort Davis, Texas, USA, uses a laser to measure the distance between the Earth and the Moon to an accuracy of 1 cm (0.39 inches). It bounces a laser off reflective targets left on the lunar surface by three US Apollo missions and two Soviet Lunokhod missions. The distance between the centres of the Earth and the Moon is 385,000 km (239,000 miles), and the laser ranging has shown that the Moon is receding from the Earth at a rate of 3.8 cm (1.5 inches) per year. This is one of the most accurate distance measurements ever made.

New Research: Closest Exoplanet to Earth Could Host Life

Posted by in category: alien life

But there’s some bad news: Proxima Centauri tends to bombard any planets in its vicinity with a ferocious amount of X rays — Proxima b receives about 400 times the amount as Earth receives from its Sun.

That leads to the question: “Is there an atmosphere that protects the planet from these deadly rays?” asked co-author Christophe Lovis, a researcher who worked on ESPRESSO, in the statement. Lovis hopes that the next generation of spectrographs — ESPRESSO’s successor, “RISTRETTO,” is already in the works — could help us find the answer.

For us to get a closer look at Proxima b however, Proxima Centauri is “only” 4.2 light-years from the Sun — meaning it would still take several thousand years to get there using today’s propulsion technology.
