There is a supermassive black hole at the center of our galaxy, and it's not alone. There is also likely a forest of binary black holes, neutron stars, and white dwarfs. All of these emit gravitational waves as they gradually spiral ever closer together. These gravitational waves are too faint for us to detect at the moment, but future observatories will be able to observe them. This poses an interesting astronomical challenge.

Old Soviet Venus lander's fall to Earth will be no ordinary space junk crash. Here's why
The Soviet Union's failed Kosmos 482 Venus probe will fall back to Earth from orbit soon, and it may well make it to the ground in one piece.
Vast to complete Haven-1 primary structure in July 2025, ahead of target May 2026 launch date
A model of the final version of Vast’s Haven-1 space station is shown with a SpaceX Dragon spacecraft docked. The model was on display at the 40th Space Symposium in Colorado Springs, Colorado in April 2025. Image: Will Robinson-Smith/Spaceflight Now
Space habitation company, Vast, is now one year away from being able to stake its claim as the first commercial space station in history.
Mars Has Many Features that Match Earth
Researchers have identified several features on Mars that look surprisingly similar to conditions on Earth. One notable feature is giant wave-like landforms called solifluction lobes, which are in cold, mountainous regions of Earth, like the Arctic or Rocky Mountains. These are slow-moving patterns similar to fluids running downhill, but on Mars, they're 2.6 times larger because of its lower gravity. They can grow much taller before collapsing on Mars.
Sun unleashes jaw-dropping filament eruption — but Earth dodges the blast (photo)
GOES-19 satellite captures breathtaking footage as a towering solar filament erupts over the sun's eastern limb.

Where does the universe's gold come from? Giant flares from extreme magnetic stars offer a clue
Scientists have finally gathered direct proof of how the universe forges its heaviest elements, a process that has remained a mystery for over half a century.
Forest satellite’s big antenna opens up
Just a week after its launch, ESA’s Biomass mission has reached another critical milestone on its path to delivering unprecedented insights into the world’s forests and their vital role in Earth’s carbon cycle – the satellite’s 12-metre-diameter antenna is now fully deployed.
Improving In-Situ Analysis of Planetary Regolith with OptiDrill
What new technologies or methods can be developed for more efficient in-situ planetary subsurface analyses? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers investigated how a novel instrument called OptiDrill could fill existing technological voids regarding the sampling and collection of regolith (top dust layer) and subsurface samples on a myriad of planetary bodies throughout the solar system.
SpaceX Falcon 9 rocket launches 28 Starlink satellites to orbit from Florida (photos)
A SpaceX Falcon 9 rocket lifted off from Florida's Space Coast on Tuesday night (May 6), carrying 28 Starlink broadband satellites into low Earth orbit.
A Single Impact Could Leave a Giant Planet Ringing for Millions of Years
To understand how chaotic the early Solar System was, we need only gaze at the Moon. Its cratered surface bears the scars from multitudes of collisions. The early Solar System was like a debris field where objects smashed into each other in cascades of collisions. The same must be true in all young solar systems, and in a new paper, researchers simulated a collision between two massive planets to see what would happen.
SpaceX gets FAA approval for 25 Starship launches per year
The FAA has approved SpaceX's request to increase the maximum number of Starship launches from its Starbase site in South Texas per year from five to 25.
