Heritage ERS-2 satellite returns to Earth

Launched in 1995, ERS-2 was a pioneering Earth observation satellite that greatly influenced our understanding of our planet and climate change. Despite an intended operational life of only three years, the satellite had a 16-year operational lifetime, and together with the almost identical ERS-1 satellite left an important legacy for the future of Earth observation.

Astronomers find first strong evidence of neutron star remnant of exploding star

An international team of astronomers including UCL’s (University College London’s) Professor Mike Barlow has discovered the first conclusive evidence that a neutron star exists at the center of Supernova 1987A, a star explosion observed 37 years ago.

New measurement of cosmic distances in the dark energy survey gives clues about the nature of dark energy

We now have a standard model of cosmology, the current version of the Big Bang theory. Although it has proved very successful, its consequences are staggering. We know only 5% of the content of the universe, which is normal matter. The remaining 95% is made up of two exotic entities that have never been produced […]

A new beginning: Astronomers search for more temperate ‘Tatooines’

Star Wars protagonist Luke Skywalker’s childhood might have been slightly less harsh if he’d grown up on a more temperate Tatooine—like the ones identified in a new study.

Enhanced 3D chemical imaging with phase-modulation

Understanding complex biological and biomedical systems is greatly aided by 3D imaging, which provides much more detailed information than traditional two-dimensional methods. However, live cell and tissue imaging remain challenging due to factors like limited imaging speed and significant scattering in turbid environments.

Experiment paves the way for new set of antimatter studies by laser-cooling positronium

AEgIS is one of several experiments at CERN’s Antimatter Factory producing and studying antihydrogen atoms with the goal of testing with high precision whether antimatter and matter fall to Earth in the same way.

A new chapter for all-attosecond spectroscopy: Researchers achieve 1 kilohertz repetition rate

A team of researchers from the Max Born Institute in Berlin has, for the first time, demonstrated attosecond-pump attosecond-probe spectroscopy (APAPS) at a repetition rate of 1 kilohertz. This became possible by the development of a compact, intense attosecond source using an out-of-focus generation geometry. The approach opens new avenues for the investigation of extremely […]

Commercial US spaceship hours from attempted Moon landing

A Houston-based company is set Thursday to land America’s first spaceship on the Moon in more than 50 years, part of a new fleet of NASA-funded, uncrewed, commercial robots meant to pave the way for astronaut missions this decade.

Little groundwater recharge in ancient Mars aquifer, according to new models

Mars was once a wet world. The geological record of the Red Planet shows evidence for water flowing on the surface—from river deltas to valleys carved by massive flash floods.

LHAASO discovers giant ultra-high-energy gamma-ray bubble, identifying the first super PeVatron

The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin of cosmic rays with energy higher than 10 Peta-Electronvolt (PeV) has been discovered. This achievement was published in the form of a cover article in Science […]

Photon upconversion: Steering light with supercritical coupling

National University of Singapore researchers and their collaborators have unveiled a novel concept termed “supercritical coupling” that enables a several-fold increase in photon upconversion efficiency. This discovery not only challenges existing paradigms, but also opens a new direction in the control of light emission.

Astronomers observe the effect of dark matter on the evolution of the galaxies

Dark matter comprises around 85% of all the matter in the universe. Although ordinary matter absorbs, reflects and emits light, dark matter cannot be seen directly, which makes its detection difficult. Its existence is inferred from its gravitational effects on visible matter, the material that forms stars, planets, and other objects in the cosmos.
