SpaceX Starship launch aborted on the pad at the last moment

SpaceX’s mega Starship rocket came within a second or so from blasting off on a test flight Thursday, but some of the engines failed to ignite, triggering a launch abort amid billowing clouds of smoke and vapor.

The starry night redux: Dark energy camera captures stars, nebulae, clusters, and more in a rich, van Gogh-esque scene

The 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam) captures a vibrant scene filled with swirls and stars reminiscent of Van Gogh’s The Starry Night. This new cosmic masterpiece features the glowing nebula NGC 6729 on the left and the globular star cluster NGC 6723 on the right. DECam is mounted on the U.S. National […]

In search of life beyond our solar system: Atmosphere detected on a habitable-zone rocky world

In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star. The finding provides the strongest evidence yet that worlds with conditions similar to Earth in composition and temperature, with the potential […]

Nearby rocky planet may be replenishing helium from atmosphere, study finds

Nearly a decade after the discovery of LHS 1140b, a rocky exoplanet in the habitable zone of a nearby low-mass star, a new study reveals that the object may have its own atmosphere.

Listening to ‘ringing’ black holes unlocks future gravitational-wave astronomy

Listening to the “ringing” produced by black holes after they collide and merge could allow scientists to test Einstein’s theory of general relativity under the most extreme conditions in the universe while unlocking the secrets of these mysterious objects.

Webb telescope discovers hidden planet in famous star system

Astronomers using NASA’s James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in the Milky Way galaxy.

How NASA’s Artemis III lander test will pave way for moon landings

Before Artemis astronauts land on the moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the moon, […]

To measure a black hole’s ultimate spin, we have to go to space

Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding how they affect their immediate vicinity and the galaxies that surround them. A new paper by Tegan Thomas of the University of […]

Spiral arms and bars are galactic fuel pumps for star formation

Peak star formation took place during cosmic noon, between 2–3 billion years after the Big Bang. The star formation rate (SFR) back then was up to 100 times greater than it is today. For the SFR to be so high, gas had to move through galaxies efficiently.

After traveling a billion kilometers, China’s asteroid hunter finally arrives

What does it take to catch up with a small, tumbling rock hundreds of thousands of kilometers from Earth? For China’s Tianwen-2 mission, the answer was a 400-day chase covering roughly 1 billion kilometers (621 million miles) of deep space—one that has just ended in success. The China National Space Administration has confirmed that the […]

Astronomers find nearby planets to be small, strange, and utterly uninhabitable

Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard’s Star—the sun’s closest neighbor after Alpha Centauri, just under six light-years from Earth.

What if disabled astronauts are just better suited to space?

The UK Space Agency and space startup Vast just signed an agreement to send Paralympic sprinter and below-knee amputee John McFall into orbit as early as 2027. Most coverage framed it as a victory for inclusion. As a space health researcher, I think something far more interesting happened.

Asteroid breakup may explain inner solar system bombardment 800 million years ago

A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological consequences on Earth. The research suggests that the catastrophic breakup of the Eulalia parent body could be linked to an impact shower that struck […]

NASA’s Perseverance rover reads record of ancient Mars impacts

NASA’s Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the “Broom Point member” by the rover’s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among […]
