The four spacecraft of NASA's PUNCH mission have successfully locked in place in Earth orbit.
The James Webb Space Telescope has revealed many wonders of the early universe, but few discoveries have puzzled astronomers more than some mysterious "little red dots." These tiny, brilliant galaxies appear scattered across deep space images like cosmic breadcrumbs, challenging everything scientists thought they knew about how galaxies formed in the early universe.
When global events set our minds to wondering if humanity has what it takes to persist, it's natural to wonder about other worlds, other life, other intelligent species, and if those others might be better suited to survive whatever Great Filters they face. Those are fanciful thoughts, but there's an underpinning of nuts-and-bolts thinking to them. It starts with identifying which planets in habitable zones around other stars might actually be habitable.
As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.
The U.S. Space Force's powerful new military radar system designed to detect and track objects in distant orbits above Earth has passed an initial key test.
Only a fraction of the size of the Milky Way, these galaxies have thus far been too faint for most telescopes to spot.
Blue Origin has used its Blue Ring spacecraft platform to develop the Mars Telecommunications Orbiter, which the company says could aid future NASA missions to the Red Planet.
The executive order directs multiple federal agencies to streamline launch licensing, fast-track spaceport construction and better support emerging in-space industries.

Europe’s first MetOp Second Generation, MetOp-SG-A1, weather satellite – which hosts the Copernicus Sentinel-5 mission – has launched aboard an Ariane 6 rocket from the European spaceport in French Guiana. The rocket lifted off on 13 August at 02:37 CEST (12 August 21:37 Kourou time).
A SpaceX Falcon 9 rocket lifted off from Florida on Thursday morning (Aug. 14), carrying 28 Starlink broadband satellites into low Earth orbit.
As 'Alien: Earth' hits screens, the night sky delivers a cameo from the franchise's iconic villain.
The future captain of the Enterprise eclipses his co-stars every time he appears in "Strange New Worlds."
The moon will drift towards the Pleiades and Uranus in the early hours of Aug. 16-17.
SpaceX's Crew-11 mission delivered four astronauts to the International Space Station for NASA, aboard a Crew Dragon spacecraft.
Mars still holds the promise of being one of the first places in the solar system humanity will colonize. However, if there was evolutionarily distinct, extant life on the planet, it might sway the heart of even the most ardent Mars colonization fans. So astrobiologists are in a race against time to try to determine whether or not such life exists, before the entire planet becomes an analogue of the Earth’s biosphere, if only unintentionally, and only a shadow of the ones that exists here. A new paper from the Christopher Temby and Jan Spacek of the Agnostic Life Finder (ALF) team discusses one of the most promising ways to prove definitively that life exists on the Red Planet - finding polyelectrolyte polymers - in other words, DNA.
Advanced satellite and lidar mapping has uncovered signs that the Tintina fault in Canada's Yukon may be primed for a powerful earthquake.

SpaceX is preparing to launch a batch of 28 of its Starlink V2 Mini satellites into low Earth orbit minutes before sunrise on Thursday morning.
Astronomers are confident that the Milky Way and Andromeda galaxies will collide, merge, or at least interact with one another in the next few billion years. What will that merger look like? Both galaxies have dwarf galaxies, and astronomers want to know if their behaviour can predict the future of the merger.
Black holes appear stranger and more bewildering the more deeply scientists study them. They display complex characteristics that defy simple explanations. One such characteristic is the vibrations they emit when perturbed.
