NASA is canceling the AXIS X-ray space telescope mission concept, saying it failed to meet key requirements. But the project leader thinks there's another reason.
In its earliest moments, the Universe was hot and dense. A plasma sea of quarks and gluons out of which hydrogen, helium, and humans eventually formed. This early cosmic state is sometimes called the primordial soup, and thanks to new research, we now know just how fitting the term is.
The Yachance Night Light star projector is a geared firmly towards children.
Here's how to clean your camera sensor to get a crisp picture every time.
Asteroid 2026 EG1 was discovered on March 8, less than one week ago.
The impetus for establishing a "Lunar Surface Moon Base" is that America is in a space race with China.
Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.
The DJI Mini 5 Pro is the best sub-250g drone ever made and now $500 off at Amazon; this Fly More Combo bundle packs in extra batteries, an LCD remote and more!
NASA will give an update about its Artemis 2 moon launch plans today (March 12), and you can watch it live.
Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.
Firefly Aerospace's Alpha rocket launched for the seventh time ever today (March 11), bouncing back from two explosive mishaps in 2025.
The Kuiper Belt, sometimes referred to as the Edgeworth-Kuiper Belt, is a circumsolar disk in the outer Solar System, extending from the orbit of Neptune at approximately 30 astronomical units (AU) out to about 50 AU from the Sun. It is similar to the asteroid belt but is much larger—20 times wider and 20 to 200 times more massive. Like the asteroid belt, it primarily consists of small bodies, but unlike the asteroid belt's rocky and metallic composition, Kuiper Belt Objects (KBOs) are primarily composed of frozen volatiles, often referred to as "ices," such as methane, ammonia, and water.
Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of physics.
In addition to being a staple of science fiction, the concept of megastructures has long been the subject of serious scientific studies. As famed physicist Freeman Dyson originally proposed in 1960, "Malthusian pressures will ultimately drive an intelligent species" to occupy an "artificial biosphere which completely surrounds its parent star." In short, he theorized that advanced civilizations would disassemble their planet (or planets) to create a structure (which has since come to be called a "Dyson Sphere" that would harness all the energy from their star and provide immense living space.
Our first satellites were little more than repeater stations that propagated our radio and tv signals around the world. But now we live in an age where a fleet of orbiting space telescopes and satellites seeks out and examines light from across the cosmos. When a powerful burst of energy flashes elsewhere in the Universe, satellites detect it, record it, and then scientists analyze it in excruciating detail.
Northrop Grumman's first "Cygnus XL" cargo ship will depart the International Space Station Thursday morning (March 12), and you can watch the action live.
Voyager Technologies is backing lunar habitat developer Max Space with a new multi-million-dollar investment aimed at accelerating development of expandable modules for future missions to the moon.
This is Part 2 of a series on interstellar comets. Read Part 1.
The disk of gas that spirals onto a newborn magnetar wobbles, creating "bumps" in the brightness of the supernova that accompanied this object's birth.
'The scope of 'Starfleet Academy' in terms of design, art direction, visual effects, practical effects, and graphics is massive.'
Astronomers have used 40 years’ worth of data to peer inside the Sun, revealing that the solar cycle can leave a distinct fingerprint beneath the visible surface.
