A million new SpaceX satellites will destroy the night sky—for everyone on Earth

More than 10,000 Starlink satellites currently orbit Earth. We see them crawling across dark skies, no matter how remote our location, and streaking through images from research telescopes.

The JWST finds more overmassive black holes. This time in dwarf galaxies

One of the things astronomers find when they look around at galaxies is a correlation between a galaxy’s mass and the mass of its supermassive black hole. Contrary to popular belief, these SMBH don’t anchor their galaxies; they make up only a small portion of a galaxy’s mass. In local galaxies, the ratio of SMBH […]

Black hole mergers test the limits of general relativity

General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from rotational frame dragging to the radiation of gravitational waves. But there is reason to believe that it is not the final say on the nature […]

Scientists detect magnetic waves deep within the sun, helping predict solar activity

Researchers at NYU Abu Dhabi have discovered new large-scale waves moving deep inside the sun, driven by magnetic fields far below the surface. These waves provide a window into parts of the sun that are otherwise inaccessible, giving scientists a new tool to study how its magnetic field is formed and evolves over time.

Giant craters may reveal if Psyche is a lost planetary core

When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in “The Empire Strikes Back,” and we often hear how they are remnants from the birth of the solar system. While the asteroids that comprise the Main Asteroid Belt of our solar system are not only […]

Artemis II astronauts arrive at Florida launch site for first moon trip in 53 years

The astronauts set to become the first lunar visitors in more than half a century arrived at their launch site Friday, joining the towering rocket that stands poised to blast off next week and send them around the moon.

He suddenly couldn’t speak in space. NASA astronaut says his medical scare remains a mystery

The astronaut who prompted NASA’s first medical evacuation earlier this year said Friday that doctors still don’t know why he suddenly fell sick at the International Space Station.

JWST solves decades-long mystery about why Saturn appears to change its spin

Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending on how you measure it? The findings, published in the Journal of Geophysical Research: Space Physics, reveal for the first time the […]

Hubble image: IC 486—where spiral arms and star formation meet

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA/ESA Hubble Space Telescope Picture of the Month image. IC 486 lies right on the edge of the constellation Gemini (the Twins), about 380 million light-years from Earth. Classified as […]

The northern lights’ dark twin is a wild card for the power grid

Scientists are working to understand how magnetic currents from the sun spread beneath Earth’s crust when the northern lights dance across the sky. Their goal is to tame its “dark twin” and prevent damage to our power grid.

NASA’s Artemis II mission will take an astronaut crew around the Moon: The long road to launch

NASA is once again shooting for the moon, for the first time since the 1970s. As soon as April 2026, NASA will launch its Artemis II mission, using the Space Launch System heavy lift rocket to send a crewed spacecraft, called Orion, into orbit. From there, the crew will circle around the moon over 10 […]

Direct confirmation of two baby planets forming around a young, sun-like star

As the number of exoplanet detections has breached 6,000 and continues to grow, scientists are finding a wide variety of different solar system architectures. Critical to understanding how these architectures take shape is finding young planets forming around very young stars. In 2025, a team of astronomers announced the discovery of a planet about five […]

Hubble detects first-ever spin reversal of tiny comet

Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence […]

Earth’s magnetic field creates a previously undetected pocket of protection from radiation on the moon

High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective shell around the planet that can deflect dangerous charged particles, like GCRs.

How did Venus become a hellscape? 234,000 simulations reveal four possible paths

Venus is increasingly becoming a touch point for our studies of exoplanets, as missions like the James Webb Space Telescope (JWST) and the upcoming Habitable Worlds Observatory (HWO) begin to characterize rocky exoplanets around other stars. Understanding the difference between the evolutions of Venus and Earth, which ended up with such different results, is a […]
