Leading X-ray space telescopes XMM-Newton and XRISM have spotted an extraordinary blast from a supermassive black hole. In a matter of hours, the gravitational monster whipped up powerful winds, flinging material out into space at eye-watering speeds of 60 000 km per second.

The Senate Commerce Committee advanced the nomination of Jared Isaacman to be NASA administrator to the full Senate in a Dec.

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

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

An international group of astronomers led by Texas Tech University assistant professor Elias Aydi published a paper titled Multiple outflows and delayed ejections revealed by early imaging of novae in Nature Astronomy on Dec. 5. The team used interferometry with the Center for High Angular Resolution Astronomy (CHARA) Array in California, combining light from multiple telescopes to obtain the hi

For decades, nuclear physicists have known that so called islands of inversion mark regions of the nuclear chart where standard shell structure breaks down and magic numbers vanish in favor of strongly deformed shapes. In earlier work these islands were identified mainly in neutron rich isotopes such as beryllium 12 with N = 8, magnesium 32 with N = 20, and chromium 64 with N = 40, all distant f

The RISTRETTO project at the University of Geneva has reached a key stage, with several core elements of its high-precision spectrograph now prototyped and tested for observations of the nearby exoplanet Proxima b. The instrument is designed to study the faint reflected light of this Earth-sized planet, which orbits Proxima Centauri at a temperature compatible with liquid water but remains outsh

The ongoing review could have implications for space projects
