Examining the delicate balance of lepton flavors

In a talk at the ongoing Rencontres de Moriond conference, the ATLAS collaboration presented the result of its latest test of a key principle of the Standard Model of particle physics known as lepton flavor universality. The precision of the result is the best yet achieved by a single experiment in decays of the W […]

Europe space telescope’s sight restored after de-icing procedure

The vision of the Euclid space telescope has been restored following a delicate operation that successfully melted a thin layer of ice that had been clouding its sight, the European Space Agency announced on Tuesday.

New NASA software simulates science missions for observing terrestrial freshwater

From radar instruments smaller than a shoebox to radiometers the size of a milk carton, there are more tools available to scientists today for observing complex Earth systems than ever before. But this abundance of available sensors creates its own unique challenge: how can researchers organize these diverse instruments in the most efficient way for […]

First observation of photons-to-taus in proton–proton collisions

In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which was made possible by using the precise tracking capabilities of the CMS detector. It is also the most precise measurement of […]

‘Unbelievable’: Video shows Ga. officers using front-end loader in pursuit of another front-end loader

A disgruntled employee stole the piece of equipment and used it to flee; after seeing the dangers of pursuing it in cruisers, an officer took over the chase in an identical piece of equipment

Euclid’s sight has been restored

A newly devised procedure to de-ice Euclid’s optics has performed significantly better than hoped. Light coming in to the visible “VIS” instrument from distant stars was gradually decreasing due small amounts of water ice building up on its optics. Mission teams spent months devising a procedure to heat up individual mirrors in the instrument’s complex […]

Saturn’s moon Enceladus top target for ESA

A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyzes them for hints of life.

SMOS and Swarm team up to spot huge solar storm

The sun erupted over the weekend, flinging electromagnetic radiation towards Earth, even illuminating skies with spectacular aurora borealis. For the first time, ESA’s unlikely space weather duo of SMOS and Swarm tracked the severe solar storm—which warped Earth’s magnetic field.

Testing begins on sensitive neutrino detector for nonproliferation and fundamental physics

Neutrinos and antineutrinos are nearly massless particles produced in many nuclear reactions, including the fission of uranium in nuclear power plants on Earth and the fusion reactions at the core of the sun.
