Dark Matter May Experience Forces Beyond Gravity
Write a comment
The mystery of dark matter continues to challenge scientists, and new findings from the Instituto de Astrofisica de Canarias (IAC) suggest that dark matter may not behave according to previous assumptions. While it is commonly believed that dark matter only interacts via gravity, a recent study indicates that dark matter experiences additional forces that may reshape our understanding of the Uni DECam Study Reveals Dense Galactic Clusters Around Early Universe Quasars

Astronomers using the Dark Energy Camera (DECam) have confirmed that early-Universe quasars are surrounded by densely packed galaxies, solving a long-standing debate. DECam's wide field of view and unique filters allowed astronomers to gain new insights into the quasar neighborhoods, explaining why previous studies have produced inconsistent results.
Quasars are extremely bright celestial Astronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet

Astronomers from the University of Arizona, along with an international group of researchers, observed the atmosphere of a hot and uniquely inflated exoplanet using NASA's James Webb Space Telescope. The exoplanet, which is the size of Jupiter but only a tenth of its mass, is found to have east-west asymmetry in its atmosphere, meaning that there is a significant difference between the two edges Nuclear strategies tested at Sandia could avert asteroid disaster

Sandia National Laboratories is exploring a coordinated nuclear response to deflect potentially catastrophic asteroids, according to physicist Nathan Moore. His team is using Sandia's Z machine-the world's most powerful pulsed-power facility-to simulate asteroid deflection scenarios and gather critical data on how asteroids of different compositions respond to such methods.
"To most people A Striped Surprise

Last week, team scientists and the internet alike were amazed when Perseverance spotted a black-and-white striped rock unlike any seen on Mars before. Is this a sign of exciting discoveries to come?
It has now nearly been a month since the rover began its climb up the steep slopes leading to the crater rim, on the hunt for ancient rocks that could teach us about early Martian history. Whil New Glenn second stage completes successful hotfire test ahead of November launch

Blue Origin's New Glenn second stage (GS2) successfully completed a critical hotfire test Tuesday, marking a key step toward its first flight, set for November from Cape Canaveral's Launch Complex 36. The NG-1 mission will carry Blue Ring technology as its first payload.
The 15-second hotfire test was the first time the vehicle operated as a fully integrated system. This test was conducted China launches eight satellites using Smart Dragon 3 rocket

On Tuesday morning, China launched a Smart Dragon 3 carrier rocket from the coast of Haiyang in Shandong province, successfully deploying eight satellites into space. According to the China Academy of Launch Vehicle Technology, the satellites were placed into their designated orbital positions shortly after the rocket's launch at 10:31 am from a launch service ship. This marks the fourth sea-bas Draco mission made for destruction

Over the nearly 70 years of spaceflight, about 10 000 intact satellites and rocket bodies have reentered the atmosphere with many more to follow. Yet for such a ubiquitous event, we still lack a clear view on what actually happens to a satellite during its fiery last moments.
ESA is preparing the Destructive Reentry Assessment Container Object (Draco) mission that will collect unique measurements during an actual reentry and breakup of a satellite from the inside. A capsule especially designed to survive the destruction will transmit the valuable telemetry shortly after.

Research abounds at the International Space Station

At the International Space station, researchers are making strides in everything from Earth science to chemical properties. Here's what they're up to and why it matters.
Recently, researchers have found that eddies, or swirling wind patterns, increased moisture evaporation in an alfalfa field. A better understanding of the complex exchange of water and heat between the ground and atmosphere could improve remote sensing products and their use in agricultural water management.
The station's ECOSTRESS instrument takes high-resolution thermal infrared measurements of Earth's surface that provide data on changes in water availability, vegetation water stress, and agricultural water use. Researchers use observations from the USGS Landsat 8 and 9 satellites and ECOSTRESS to validate climate models and update data on Earth's surface energy (the amount of energy absorbed from the sun and radiated back into the atmosphere).
