Astronomers are testing a new way to measure how fast the universe is expanding by using time delays in gravitationally lensed images of distant quasars, in an effort to clarify the long-standing tension between different measurements of the Hubble constant. The expansion rate of the universe, known as the Hubble constant, describes how quickly galaxies recede as a function of distance, wi

Gamma ray bursts rank among the most energetic explosions known, usually flashing and fading within seconds or minutes, but on 2 July 2025 astronomers detected GRB 250702B, a source that produced repeated bursts for over seven hours and now stands as the longest gamma ray burst yet observed. Space based observatories, including NASAs Fermi Gamma ray Space Telescope, first recorded the gamma rays

Rocket Lab Corporation has qualified the captive Hungry Hippo fairing for its Neutron launch vehicle and is sending the structure to Virginia for integration ahead of the rocket's debut mission. The fairing halves remain attached to Neutron's first stage from liftoff through landing, rather than separating and being discarded or recovered at sea. In flight, the halves open to release the second

A structural model of the upcoming Copernicus Radar Observing System for Europe at L-band satellite, or ROSE-L for short, has recently been put through a series of demanding tests – including intense vibration – to demonstrate that the satellite will be able to withstand the stresses of launch and operations in orbit.

Once in orbit, ROSE-L’s data will support a wide range of applications, from soil moisture and crop monitoring to forest mapping, maritime surveillance, and the detection of natural and human-induced hazards.

Spire Global has been selected by GIST Research to supply satellite-derived Soil Moisture Insights for a project that links climate conditions to pastoralist movements and conflict risks in Ethiopias Somali Region. The work feeds into the International Organization for Migrations Transhumance Tracking Tool, which monitors herder routes and is used to anticipate tensions around scarce resources.
