A paper published in the journal Monthly Notices of the Royal Astronomical Society hints at the existence of several black holes in the Hyades cluster — the closest open cluster to our solar system — which would make them the closest black holes to Earth ever detected.
Researchers at the Center for Functional Nanomaterials (CFN), a U.S. Department of Energy (DOE) Office of Science User Facility at DOE’s Brookhaven National Laboratory, and Northrop Grumman, a multinational aerospace and defense technology company, have found a way to maintain valley polarization at room temperature using novel materials and techniques.
Russian scientists have modelled atmosphere of the well-known “hot Jupiter” HD 189733b and found out what hindered from stable finding of hydrogen in the atmosphere of the planet. They also defined physico-chemical properties of this planetary system.
New research has revealed the distribution of dark matter in never before seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints on the nature of dark matter.

Using the Gemini North telescope, one half of the International Gemini Observatory, operated by NSF’s NOIRLab, astronomers have detected for the first time evidence of the presence of an accretion disk within the active galactic nucleus of galaxy III Zw 002. Using two rare and peculiar near-infrared emission lines, these observations place firm limits on the size of the galaxy’s accretion disk and shed new light on its geometry and behavior.

A team of researchers, including NOIRLab astronomer André-Nicolas Chené, has found a highly unusual star that has the most powerful magnetic field ever found in a massive star — and that may become one of the most magnetic objects in the Universe: a variant of a neutron star known as a magnetar. This finding marks the discovery of a new type of astronomical object — a massive magnetic helium star — and sheds light on the origin of magnetars.

After appearing in the Bond film, “GoldenEye,” the Arecibo Observatory was the world’s largest radio telescope until December 2020, when its cable wires slipped causing the platform to collapse. Neutron imaging on failed cable sockets was performed at Oak Ridge National Laboratory.
Among the many hazards encountered by space probes, exposure to radiation and huge temperature swings pose particular challenges for their electronic circuits. Now KAUST researchers have invented the first ever flash memory device made from gallium oxide, a material that can withstand these harsh conditions far better than conventional electronics.
In a new study, researchers have taken an important step toward understanding how exploding stars can help reveal how neutrinos, mysterious subatomic particles, secretly interact with themselves. One of the less well-understood elementary particles, neutrinos rarely interact with normal matter, and instead travel invisibly through it at almost the speed of light.
The University of Adelaide’s Plants for Space program has attracted international investment from the UK Space Agency, through industry partner Vertical Future (VF).
Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are in the journal Nature.
The largest storm in the solar system, a 10,000-mile-wide anticyclone called the Great Red Spot, has decorated Jupiter's surface for hundreds of years. A new study now shows that Saturn — though much blander and less colorful than Jupiter — also has long-lasting megastorms with impacts deep in the atmosphere that persist for centuries.
A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred to as wide binaries in astronomy and astrophysics.
A study of rare megastorms on Saturn using data from the National Science Foundation’s Karl G. Jansky Very Large Array has revealed disruptions in the distribution of ammonia gas in the planet’s deep atmosphere. The findings raise questions about just how different gas giants can be from each other, and challenge scientists’ understanding of how megastorms may form on planets other than Earth. The results of the study appear in Science Advances.
Many as-yet-undiscovered interstellar objects exist throughout our Milky Way Galaxy: comets and asteroids that have been ejected from their home star systems. Some of these objects pass through our Solar System, bringing valuable information about how planetary systems form and evolve. Currently, only two such interstellar visitors have been discovered: 1I/ʻOumuamua and comet 2I/Borisov. Rubin’s upcoming Legacy Survey of Space and Time will show us many more.

Muchos objetos interestelares aún no descubiertos existen en nuestra Vía Láctea. Se trata de cometas y asteroides que fueron expulsados de sus sistemas estelares de origen y que vagan por el espacio entre las estrellas. Algunos de estos objetos atraviesan nuestro Sistema Solar y aportan valiosa información sobre la formación y evolución de los sistemas planetarios. Actualmente, sólo se han descubierto dos visitantes interestelares de este tipo, ʻOumuamua y el cometa Borisov. La próxima Investigación del Espacio-Tiempo como Legado para la posteridad de Rubin revelará muchos otros objetos de este tipo.

The surface of Mars, unlike the Earth's, is not constantly renewed by plate tectonics. This has resulted in the preservation of huge areas of terrain remarkable for their abundance in fossil rivers and lakes dating back billions of years.
New observations of mud cracks made by the Curiosity Rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments, indicating that the red planet may have once seen seasonal weather patterns or even flash floods.
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star yet. This star, nicknamed Earendel, emitted its light within the universe’s first billion years.
Dr. John Bennewitz, an assistant professor in the Department of Mechanical and Aerospace Engineering at The University of Alabama in Huntsville (UAH), has been awarded a $650,000, 45-month Air Force Office of Scientific Research (AFOSR) grant to develop an advanced propulsion system that will facilitate surveillance of space between the Earth and the Moon by the United States Space Force.

Mehr Un Nisa, a postdoctoral research associate at Michigan State University, who will soon be joining MSU’s faculty, is the corresponding author of a new paper in the journal Physical Review Letters that details the discovery of the highest-energy light ever observed from the sun.
During a dive through archival data, astronomers unearth an unusual tidal disruption event that occurred in a nearby star-forming galaxy. Obscured by the interstellar medium, this incredibly close and luminous event went unnoticed for seven years. The SOAR telescope’s integral role in pinpointing its uncommon location illustrates how future searches for tidal disruption events will be conducted.

The Fishhook. The Thin One. These are just two of the striking targets revealed in new detail by NASA’s James Webb Space Telescope. In July 2022 Webb observed El Gordo, a galaxy cluster that existed 6.2 billion years after the big bang. It was selected as the most massive galaxy cluster known at that time in cosmic history.
In May, a newly visible supernova dotted one of the spiral arms of Messier 101, also known as the Pinwheel Galaxy. Dubbed SN 2023ixf by NASA, it’s the closest supernova spotted in five years. An explosion of a dying star, the supernova was visible through amateur telescopes and had both hobbyist astronomers and experts abuzz over catching a glimpse, sharing tips for getting it in sight, and taking long-exposure photographs.
An asteroid discovery algorithm — designed to uncover near-Earth asteroids for the Vera C. Rubin Observatory’s upcoming 10-year survey of the night sky — has identified its first “potentially hazardous” asteroid, a term for space rocks in Earth’s vicinity that scientists like to keep an eye on.
