U.S. Naval Research Laboratory (NRL) researchers have discovered solar-wind hydrogen in lunar samples, which indicates that water on the surface of the Moon may provide a vital resource for future lunar bases and longer-range space exploration.
The CAIRT satellite mission is becoming increasingly likely. The European Space Agency (ESA) has now selected the concept, that was coordinated by Karlsruhe Institute of Technology (KIT), as one of two remaining candidates for an Earth observation mission. The final decision for implementation will be made in 2025.
Astronomers at the University of Leeds have discovered that massive Be stars, thought to exist in double stars, could in fact be "triples". This could revolutionize our understanding of these stars and the formation of black holes and neutron stars
Our own Milky Way galaxy is part of a much larger formation, the local Supercluster structure, which contains several massive galaxy clusters and thousands of individual galaxies.
Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our Local Universe called the Supergalactic Plane.

NASA's Lucy mission discovers a binary asteroid, Dinkinesh, with a small satellite
In 2008 NASA’s Spitzer Space Telescope found a protoplanetary disk unlike any other. The dusty disk of gas surrounding the young Sun-like star SZ Chamaeleontis (SZ Cha) was being pummeled by extreme ultraviolet radiation – something previously seen only in computer models, never in the real universe. Planets in this system would have more time to form than in a disk being evaporated by X-rays, which is the norm. However, when the James Webb Space Telescope followed up on SZ Cha, it found nothing out of the ordinary – no abundance of ultraviolet radiation. In a short space of cosmic time, conditions in SZ Cha’s disk had changed, leaving astronomers to untangle meaning from the mismatched data and its implications for the formation of other solar systems.
The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them.

An international team led by scientists from the University of Liège has observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper atmosphere of the Red Planet and its variations throughout the year.
When two flagship observatories unite, they reveal a wealth of new details only possible through their combined power. Webb and Hubble have joined forces to study the galaxy cluster MACS0416, located about 4.3 billion light-years from Earth. Their combined data yields a prismatic panorama of blues and reds – colors that give clues to the distances of the galaxies.
Un equipo de astrónomos consiguió capturar en imágenes los restos erosionados de más de un centenar de galaxias enanas que se están transformando en galaxias enanas ultra compactas, es decir, en objetos con masas mayores que la de los cúmulos estelares, pero mucho más pequeñas que las galaxias enanas. Los hallazgos fueron realizados utilizando el telescopio de Gemini Norte, la mitad boreal del Observatorio Gemini que opera NOIRLab de NSF y AURA, y confirman que muchas galaxias enanas ultra compactas son probablemente los fósiles de galaxias enanas normales cuyas capas exteriores se desprendieron.

Astronomers using the Gemini North telescope, one half of the International Gemini Observatory operated by NSF’s NOIRLab, have captured the eroding remains of more than 100 dwarf galaxies as they transition into ultra-compact dwarf galaxies, objects with masses much greater than star clusters yet much smaller than dwarf galaxies.

The James Webb Space Telescope has witnessed the planet-forming process in action, revealing a connection between water vapor in the inner disk and the drifting of icy pebbles from the outer disk. This finding opens exciting, new vistas into the study of rocky planet formation.
This blog post celebrates highlights from the brilliant career of astronomer Paul Vanden Bout, who recently received the Karl G. Jansky Lectureship from NRAO. Vanden Bout's vision for millimeter-wavelength astronomy led to the creation of several major radio telescopes around the world.
Quasars can be obscured by dense clouds of gas and dust in their host galaxies, not just by donut-shaped rings of dust in the close vicinity of the black hole.
Disorientation puts astronauts in danger — now scientists have developed wearable vibrotactile devices to keep them on track
New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.
In the 1980s, geophysicists made a startling discovery: two continent-sized blobs of unusual material were found deep near the center of the Earth, one beneath the African continent and one beneath the Pacific Ocean.

Multimode fiber (MMF) lasers can be invaluable for various applications, including high-energy pulse generation, precision measurement, and nonlinear microscopy. They also serve as an outstanding testbed for nonlinear spatiotemporal physics. The generation of ultrashort pulses in nonlinear multimode resonators relies upon spatiotemporal mode-locking (STML), which involves synchronization in both spatial and temporal dimensions. This review focuses on the fundamentals of STML, with a particular emphasis on the dynamics under large intermode dispersion. Recent progresses in spatiotemporal measurement techniques, exotic nonlinear dynamics of spatiotemporal dissipative solitons (STDS), and spatial mode engineering in MMF lasers are covered. We also provide an outlook on future perspectives for STML.

Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars.
Although the Crab Nebula is one of the most well-studied supernova remnants, questions about its progenitor and the nature of the explosion that created it still remain unanswered. NASA’s James Webb Space Telescope is on the case as it sleuths for any clues that remain within the supernova remnant. Webb’s infrared sensitivity and spatial resolution are offering astronomers a more comprehensive understanding of the still-expanding scene.

Gemini South, one half of the International Gemini Observatory operated by NSF’s NOIRLab, captures the billion-year-old aftermath of a spiral galaxy collision. At the heart of this chaotic interaction, entwined and caught in the midst of the chaos, is a pair of supermassive black holes — the nearest pair to Earth ever recorded.
