Since the 1960s, astronomers have theorized that the Universe may be filled with a mysterious mass that only interacts with “normal matter” via gravity. This mass, nicknamed Dark Matter (DM), is essential to resolving issues between astronomical observations and General Relativity. In recent years, scientists have considered that DM may be composed of axions, a class of hypothetical elementary particles with low mass within a specific range. First proposed in the 1970s to resolve problems in the Standard Model of particle physics, these particles have emerged as a leading candidate for DM.

Live coverage: NASA, SpaceX to undock Crew-8 following weeks of weather-related delays, scheduling conflicts
The three astronauts and cosmonaut of the SpaceX Crew-8 mission finally have a return date to Earth following more than seven months in space.
Mini '2001' monoliths fly into space on first flight of Blue Origin's 2nd crew ship
A number of black slabs modeled after the monoliths in "2001: A Space Odyssey" have made the trip into space and back on the first flight of Blue Origin's second human-rated launch vehicle.
Spooky fireball blazes across Lake Erie a week before Halloween (video)
A fireball lit up the skies over Lake Erie on Monday (Oct. 21) evening, eliciting hundreds of witness reports to the American Meteor Society.
NASA is Building Telescopes for the LISA Mission
Some of the most cataclysmic and mysterious events in the cosmos only reveal themselves by their gravitational waves. We’ve detected some of them with our ground-based detectors, but the size of these detectors is limited. The next step forward in gravitational wave (GW) astronomy is a space-based detector: LISA, the Laser Interferometer Space Antenna.
Boeing-built communications satellite breaks up in orbit. 'Total loss,' operator says
The Intelsat-33e satellite is in pieces following some kind of problem in geostationary orbit, according to the company and US Space Force. An investigation is ongoing.

Watch SpaceX Crew-8 astronauts undock from ISS today after weather delays
SpaceX's Crew-8 astronaut mission for NASA will undock from the International Space Station Oct. 23 after several weather delays, then splash down. Watch both events live.
There's a Particle Accelerator at the Center of the Milky Way
Nestled on the slopes of Cerro La Negra at an elevation of 13,000 feet is an unusual-looking observatory. Known as the High-Altitude Water Cherenkov (HAWC) observatory, it looks like a tightly packed collection of grain silos, which is essentially what it is. But rather than holding grain, the silos are each filled with 188,000 liters of water and four photomultiplier tubes. While it’s an unusual setup, it’s what you need to observe high-energy gamma rays from deep space.
Tom Hardy says farewell to the alien symbiote at NYCC's 'Venom: The Last Dance' panel
Tom Hardy talked about the third and final Venom movie, "Venom: The Last Dance," last weekend during a panel discussion at New York Comic Con.
1st triple black hole system discovered in 'happy accident'
The first "black hole triple" system, consisting of a black hole hungrily feeding on a companion star orbited by a more distant star, hints at a gentle formation process without supernova explosions.
First young brown dwarfs found outside the Milky Way?
An international team of astronomers has used the NASA/ESA/CSA James Webb Space Telescope to detect the first brown dwarf candidates outside the Milky Way in the star cluster NGC 602.
ULA begins stacking Vulcan rocket in anticipation of first national security mission
United Launch Alliance (ULA) hoists its Vulcan first stage booster into the Vertical Integration Facility-G (VIF-G) adjacent to Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida. The rocket will launch the USSF-106 mission for the U.S. Space Force’s Space Systems Command, Vulcan’s first national security flight. Image: United Launch Alliance
Less than a month after the second of two planned certification launches, United Launch Alliance is getting a Vulcan rocket ready for its first national security mission: United States Space Force 106 (USSF-106).
James Webb Space Telescope sees lonely supermassive black hole-powered quasars in the early universe
The James Webb Space Telescope has discovered lonely quasars in the early universe, with "empty larders" that defy theories surrounding their growth to monster sizes.
SpaceX's Starlink internet flies on a Boeing 777 jet for the 1st time
SpaceX's Starlink satellites provided internet service on a Boeing 777 jet for the first time today (Oct. 22), during a Qatar Airways flight from Doha to London.
New Research Reveals Provides Insight into Mysterious Features on Airless Worlds
Between 2011 and 2018, NASA’s Dawn mission conducted extended observations of Ceres and Vesta, the largest bodies in the Main Asteroid Belt. The mission’s purpose was to address questions about the formation of the Solar System since asteroids are leftover material from the process, which began roughly 4.5 billion years ago. Ceres and Vesta were chosen because Ceres is largely composed of ice, while Vesta is largely composed of rock. During the years it orbited these bodies, Dawn revealed several interesting features on their surfaces.
SpaceX to launch 23 Starlink broadband satellites from Florida on Oct. 23
SpaceX plans to launch 23 more of its Starlink internet satellites from Florida's Space Coast on Wednesday evening (Oct. 23).
Fall back to Earth with Falcon 9 payload fairings in stunning new SpaceX video
A recent SpaceX Starlink launch featured an extra video treat: a view of the Internet satellites being revealed for future Internet service. But Starlink's effects on astronomy still causes concern.
Testing Heat Shields for Different Atmospheres
Testing is one of the unsung steps in the engineering process. Talk to any product development engineer, and they will tell you how big of a milestone passing “V&V” – or verification and validation – testing is. Testing is even more critical when you work on equipment meant for the harsh space environment. It is also more challenging to mimic those harsh environments on Earth. Luckily for some of NASA’s more critical upcoming missions, another government agency has a unique test lab to help V&V with some of its most critical components – their heat shields.
