Distant quasar J0439+1634 explored in X-rays
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on the arXiv pre-print server,.....»»
Image: Earth through a 2-mm lens
A distant, partly shadowed Earth, as viewed from a 6,000-km-altitude orbit. This unusual image was acquired using an extremely miniaturized camera about the size of the edge of a 20 cent coin—a miniscule technology experiment aboard ESA's shoebox-s.....»»
X-rays reveal all the differences between authentic AirPods and counterfeits
Counterfeit Apple products are a real problem. Earlier this year we saw US officials seize over a thousand fake AirPods and Apple Watches. And Apple has a dedicated team for dealing with illegal knockoffs. While good counterfeits may look very convin.....»»

How close is too close to a kilonova?
Cataclysmic events happen in the universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to us. But there are a few that could affect life on.....»»

Realizing vertical ultraviolet-B semiconductor laser diodes for high optical output
Ultraviolet (UV) rays are electromagnetic waves with wavelengths ranging from 100 to 380 nanometers (nm). These wavelengths can be classified into three regions: UV-A (315–380 nm), UV-B (280–315 nm), and UV-C (100–280 nm), with the latter two c.....»»
Astronomers detect most distant fast radio burst to date
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Larg.....»»
