Dense stellar environments were common in the early Universe. These environments fostered more numerous stellar collisions, and some of those would've been mergers that formed very massive stars.…

A team of scientists is exploring ways to use dark craters at the lunar poles as sites for ultrastable lasers to aid in surface and near-lunar navigation.…

Building a permanent base on the Moon sounds like an engineering problem. Design the habitat, sort the power supply, figure out life support, and you're most of the way there.…

When it comes to understanding Earth and our changing environment, space is the place. Not only does it give us an overall holistic view of the planet below, but satellite-based imagery can transcend national boundaries and give us an understanding of key…

The Sun has a heartbeat. Every eleven years it swells with magnetic fury, hurling solar flares and charged particles into space, sparking auroral displays and threatening power grids, all before quietening down again.…

A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical puzzles across vastly different environments.

Enigmatic crownlike surface formations on Venus hold keys to understanding our twin planet’s deep interior. Or so says a new paper presented at the recent European Geosciences Union 2026 general assembly in Vienna.

A study of NASA's Black Marble data reveals a pattern of regional volatility in nighttime illumination across the planet.

Earth has a group of cosmic stalkers. Known as “co-orbitals”, these small bits of rock have a 1:1 mean motion resonance with Earth. Basically, they take the exact same amount of time to orbit the Sun as we do.…

Dark matter makes up roughly 85 percent of all the matter in the universe. We have never directly detected a single particle of it. But a new method developed by physicists at MIT and across Europe may have just opened a door we didn't know existed.…

Artemis II has barely left the headlines. On April 1st 2026, four astronauts climbed aboard NASA's Orion spacecraft, rode the most powerful rocket ever to carry humans beyond low Earth orbit, and swung around the far side of the Moon. The world watched.…

For ten years, astronomers at UCLA have been pointing one of the world's most powerful radio telescopes at the stars and listening. Not for pulsars or gas clouds, or the hiss of the cosmic microwave background, but for something far more extraordinary.…

Shalbatana Vallis is a 1300 km water channel on Mars. It was carved out in one cataclysmic flooding event, possibly triggered by a massive impact. It's more evidence that liquid water once flowed on Mars.

University of Cincinnati astrophysicist Paul Smith is part of an international team studying TOI-2031Ab, a gas giant orbiting a star 901 light years from Earth. Smith and his colleagues used the James Webb Space Telescope to study its atmosphere.

One of the core community surveys of NASA’s Nancy Grace Roman Space Telescope, the Galactic Bulge Time-Domain Survey, is expected to locate over a thousand exoplanets that orbit far away from their stars, beyond the orbital distance of Earth from the Sun.…

Perseverance has travelled almost 26 miles, or 42 km. That's just shy of a marathon, which is 26.2 miles or 42.195 kilometers. Along the way, it's abraded and studied 62 rocks and collected 27 rock cores. And it's not done yet.

When a massive star dies, it can leave behind a black hole. That much has been understood for decades. But the most monstrous black holes in the universe, the heavyweights detected by the faint ripples they send through the fabric of space and time aren't…

Hot Jupiters are the bullies of the planetary world. These colossal gas giants orbit impossibly close to their stars and their gravity is so overwhelming that anything nearby gets scattered, swallowed, or flung into oblivion.…

Every time an astronomer points a telescope at a distant supernova, they're trying to measure how far away it is. But the light from these stellar explosions arrives tangled up with interference from dust, the age of the host galaxy and the chemical make…

During the 1970s, pioneering experiments were conducted that are known today as Messaging Extraterrestrial Intelligence (METI). At the same time, NASA launched four spacecraft bound for interstellar space, each carrying
