A deep partial solar eclipse will grace the Southern Hemisphere on Sept. 21, 2025, with the best views from remote seas and New Zealand's dawn skies.
NASA's Psyche Mission launched in October 2023 to rendezvous with the asteroid of the same name. The Psyche asteroid is a metal-rich asteroid that could be the remnant core of a planetesimal that had its outer layers stripped away. It's due to reach the asteroid and begin orbiting it in 2029.
When the James Webb Space Telescope (JWST) commenced operations, it provided the first views of the period known as Cosmic Dawn. This cosmological epoch, which took place between 50 million and one billion years after the Big Bang, was when the first stars and galaxies in the Universe formed. What Webb's observations revealed of this period surprised and intrigued scientists. In addition to spotting numerous "Little Red Dots" (LRDs), particularly bright and red galaxies, it also observed the "seeds" of Supermassive Black Holes (SMBHs).
The Moon, Earth's only natural satellite, is a celestial body that has fascinated humanity for millennia. Its presence in our night sky has inspired myths, legends, and scientific inquiry. This document provides a concise overview of some key facts about the Moon.
If there's one thing astronauts know, it's "practice, practice, practice."
This quiz will explore the science behind the scenery, the facts behind the familiar, and the wonders that make Earth a living planet.
Join us as director Valerie Weiss breaks down this 'Trekiest' episode of the sci-fi series yet.
The U.S. Space Force's X-37B space plane will test a potential alternative to GPS that makes use of quantum science as a tool for navigation: a quantum inertial sensor.
There are things astrophysicists know and things they don't know about brown dwarfs. They know that as they were forming and accreting mass, they failed to gain enough mass to trigger hydrogen fusion and become stars. But they're too massive to be gas giant planets like Jupiter because they do fuse some deuterium. So brown dwarfs are stuck in an astrophysical no-man's-land between star and planet. They're often referred to as 'failed stars'.
The U.S. Department of Defense’s mini-shuttle heads to orbit once again Thursday night.
In May 2027, NASA's Nancy Grace Roman Space Telescope will launch to space. Appropriately named after the "Mother of Hubble," the telescope will use its 2.4-meter (7.9 ft) wide field of view primary mirror and advanced instruments to investigate the deeper mysteries of the cosmos. Roman will spend 75% of its observing time over its five-year primary mission conducting three core community surveys selected by the scientific community. Among them, Roman will conduct a High-Latitude Time-Domain Survey (HLTDS) to detect tens of thousands of type Ia supernovae.
Chappell Roan mentioned Canada's Saskatchewan just days before Cypress Hills Interprovincial Park hosts a "star party" festival in its dark-sky park.

Firefly Aerospace may soon bring its Alpha rockets to the coast of Japan.
Acting NASA Administrator Sean Duffy says it's time for the agency to focus on the moon and Mars, not the "smorgasbord of priorities," like climate science, the agency has been directing its resources.
After five years, Pragmata could have been unambitious, but instead, it's a fascinating and innovative sci-fi game with heaps of potential.
South Korea's K-RadCube satellite has arrived at NASA's Kennedy Space Center in Florida ahead of its launch toward the moon on the Artemis 2 mission next year.
